queued call

While  a caller waits for a UCD group  member  to answer (in queue),  several  queued call operations are possible.   These  include the  following. •   No Answer – Member  advancement.  Each UCD  group has a No  Answer  Timer.   You can set this timer to  advance the call from one UCD group member to the next when the ringing  member does not answer  the call  within the  time allotted. •   Overflow  1 Destination programming.  Each  UCD  group has  an overflow 1 timer and destination.   You can set this timer  to determine how long calls  will  remain in queue,  before being routed  to the  overflow 1 destination.  The destination can  be an extension  responsible for handling  calls that  remain in  queue too long, or a voice  announcement device.  You  can use recorded announcement devices  to  play recorded messages  to callers  waiting in queue, for example, “All agents are still  busy  - please continue to hold.”   The system  plays the overflow  1  destination only once.   For high  traffic  scenarios,  you can  use  a  recorded voice announcement UCD group to play the  same  message to multiple callers. •   Overflow  2 Destination programming.  Each  UCD  group has  an overflow 2 timer and destination.   You can set this timer  to determine how long calls  will  remain  in queue, following  the overflow 1 timer, before being routed  to the overflow  2  destination (overflow 1  timer + overflow  1 destination recorded message time + overflow 2  timer.)   The destination can be  an  extension responsible for handling calls that remain in queue too long or a voice announcement device.   You can use  recorded announcement devices to  play  recorded  messages to  callers waiting in queue, for example, “Please continue  to hold to  reserve  your place in  queue.”   For high  traffic scenarios, you can use a recorded voice  announcement UCD  group to play  the same message to multiple callers. •   Overflow Count  programming.  Each UCD group has an overflow  count that is  associated with the  overflow 2 timer.   You can set  this timer to  allow a specific number  of times  that the  system may repeat the  overflow  2 timer.  For each cycle  of  the overflow 2 timer, the  system plays the overflow 2 destination  recording.   If a call  remains in queue so  long that the overflow count counter expires,  the system routes  this  call to the programmed  reroute  destination. •   Reroute Destination programming.   Each  UCD  Group has a reroute  destination.   You can program this  with an  extension number the system uses  to remove  the call from UCD  group queue.   The system  then routes the  call for immediate handling. Other features whose  programming may affect  UCD programming  includes the following. •   CO Line Ring  Assignment •   UCD Reroute  Destination •   UCD Voice Announce Group •   UCD Agent Log On/Log  Off •   Voice Mail -  Digital Integration •   Recorded  Announcement Devices (RADs)

Remote connection

Remote connection to  the  DX-80 system is possible via  modem.   The optional modem may be  purchased allowing remote administration of the  DX-80 system database  and maintenance operations.  The  default directory  number of  the  modem is  199.   Some  working  knowledge of  modem operation and connection is useful. 3.5.4.11  F10-RS232C This  function key is used to  setup  the PC  COM port.  To  successfully setup the PC COM  port you  must know  how the PC hardware is configured.   In this utility  you must select  the COM Port number (PCDBA supports COM 1 or 2 only) and the baud rate that  will be used for the connection.  At default PCDBA  is setup to  use COM Port  1  at 9600  bps.  (9600  bps matches the  default  baud rate set for  the  DX80 CPM – PC-DBA Port.) While using a modem connection, it  is  best to  set the  COM port baud  rate at 2400  bps since this is the speed of the  DX-80 optional modem; setting this speed can expedite the modem negotiation  process since compression  link choices will not  be attempted.

system Maintenance

System Maintenance Maintaining the  Comdial DX-80 digital telephone system is a combination of customer database changes,  facilities and apparatus moves, adds  and  changes.  These requirements are accomplished by practicing the  techniques, illustrations  and step-by-step instructions listed in the previous sections of this manual. When properly installed,   the  Comdial DX-80  is relatively maintenance-free.   From time to time the digital  telephone instruments may  become  dirty or dusty  and require cleaning.   We  suggest the use  of  a clean,  dry cotton (or other  soft,  absorbent) cloth  to  wipe the instrument  clean.  The use  of  chemicals to clean the telephone  plastics  is NOT recommended  since  some  chemicals  can cause permanent  damage to the telephone finish.  If deep  soiling conditions exist, many specialized telephone cleaning solutions  will provide satisfactory results.    When trying  any cleaner for  the first time, apply  the cleaner  to a small  sample area on  the underside of the instrument.   If the expected  results  are  achieved, proceed with cleaning  the remainder of  the telephone.

Serial Cable for SMDR SMDR (Station Message Detail Recording)

Connecting a Serial Cable for SMDR SMDR (Station Message  Detail Recording)  can be output from  the DX-80  system  for use with serial printers of  collection in call accounting devices. Connection  of the SMDR  device to  the DX-80 is accomplished  through the  serial data port on  the CPM  labeled “SMDR.” Connection  to  serial printers may  require customization  of  the  serial cable used  to make the  connection. CPM“SMDR” serial port connector (straight- (Dedicated means that this AC outlet has no other equipment connected on this circuit breaker.  Whenever a  call accounting system  (third-party device) is deployed,  connection is often  no  more  complicated than  using  a straight-through, 9-pin, female  to  male,  serial  cable. (Use Radio Shack model 26117B for good  results.) Connection to the PC/call accounting system is  made via an  available 9-pin serial port connector that is designated as COM1 or COM2  in the PC configuration. Once the cable is linked between  the collection device and the DX-80 CPM-SMDR port, the collection device  must  be  programmed  for compatible  link protocol (baud rate). At default the SMDR  port baud rate is set  at 9600  bps.

Assigning a password

Assigning a Password  to the Extension All extensions of the DX-80 system have an  associated user password.   Passwords  are required to use  Phone  Lock,  Call  Forward  Remote, and Attendant features.   Note:   Extension passwords  can be changed  at  the extension  only by using  the Phone Lock  feature. Passwords can be  from four  to  eight characters  in length.   You  may  want to program the overall system password length before programming individual  extension  passwords.   See  Section 4.4,  Setting User Password  Lengths, Setting Passwords for System Directory  Numbers  101, 102,  and  108  for more details. Changes to  the length of the  user  password affect existing passwords—the system adds or  subtracts one default character  to  the end of  the  password.  That is,  if you extend the length  of  the password, the system increases all passwords by adding a 0 in the  right-most  position.   If you  reduce the  length of the password, the system truncates all passwords  by one  character in  the right-most position.

Press Y to save your changes

The  system prompts “Save Current Setting?”   Press  Y  to  save  your changes. 9. The  system  then  prompts “File Exists, Override?”   Press  Y  to  continue with the save operation. 10. Press  Esc  to return to the  Uniform Call Distribution: Parameter Processing: Hunt  Group 24 menu.  Press  Esc  three times more to return to  the Database Programming  menu. 11. Next,  program the voice mail  hunt  group.   Highlight  Voice Mail  Table, and  press  Enter.  Choose the tenant  group  you want  to program, and press Enter.   The  system  displays the  Extension Application—Voice Mail  Table: Tenant  x  menu.

KSU1

You can add one AAM to the KSU1.  The  AA  Module  adds  automated attendant  functionality to the DX-80 system with 10 integrated  announcements.   The  AAM does  not  provide voice mail functions. For details on how to program the AAM  and its announcements, refer to the  DX-80 Technical  Manual, Volume  II,  Programming. Install  the AAM onto designated  connectors located on the CPM. To  install the AAM perform the  following steps. 1. Be sure  that the  entire system is turned off. 2. Remove the  KSU  cover (four screws at each corner). 3. Connect  a static discharge  wrist  strap to a  suitable  earth  ground.   Be sure  that the strap  is touching bare skin.

Third Party VM, Analog Ports You can connect the DX-80

Programming Third  Party VM, Analog Ports You can  connect the DX-80 system  to  a third-party voice mail system using spare analog  ports.  Doing so  occupies these ports and therefore reduces the  number  of system ports that  you can use for the telephones, FAX machines, modems, etc. Comdial recommends  using the  DX-80 DX-SO  voice  mail  system, because  it is a digital  integration and therefore does not occupy valuable analog port space of the DX-80  system.  For further details,  see Section 9.2,  Programming Optional Internal VM,  Digital. Using voice mail greatly enhances  the  use  of the  DX-80 system.  Features  accessible  when voice  mail is installed  vary  depending  upon  the  third-party  product connected.   Features  that the  DX-80 system accommodates include the following. •   Automated Attendant •   Extension unique voice  mailboxes •   Call  Forward to extension voice mailboxes •   Answering Machine Emulation •   UCD Queue  Announcements •   Menu Routing •   Voice Record •   Automatic Voice  Record •   Specific  CO  Line  Greetings on  Automated Attendant The following  conditions apply to analog voice  mail. •   Voice mail  feature  operation is limited  only by the ancillary voice mail  system. •   When voice mail ports are used  heavily (high call  traffic), the  system  updates message indications  notably slower than usual. •   When VM  messages are waiting, the  system flashes the auxiliary lamp green.

COM4

Adding a COM4 You can add one COM4  to KSU1  and  one COM4  to  the KSU2.   These modules  expand  the  DX-80 system  CO  line  interface  capacity to a  maximum of eight  CO line  ports in each KSU  (16 total CO line ports when used in KSU 1 &  2). When  adding  a COM4 to  either KSU,  connect to  the  408M/E  via the COM4  module ribbon  cable.  This ribbon cable has the logical system  address  of SLOT 5  in both cabinet 1 (KSU1-408M) and cabinet  2 (KSU2-408E).   COM4 modules are  installed using  four  1.5 cm brass-color standoffs.   Always install  the COM4  module beneath the  CPM  module (in KSU1) by first  removing the CPM, installing the  COM4,  and then re-installing the CPM.  This is required whenever  you install  the InSkin Voice  Processor.

equipped with a heartbeat LED

The  408M is equipped with a heartbeat LED that  indicates processing  activity  on  the PCB.  (The 408M peripheral processor  is  operating when  the heartbeat LED  is flashing.)  The KSU1 operation LED (located  next  to the power switch) is  tied to the  408M heartbeat LED.   Therefore,  when  the  LED next to the power switch is flashing,  the 408M is active. The  KSU1-408M  has three ribbon cables: •   located at the upper  right and oriented  in a horizontal  position, the J1  cable is used to interface a COM4  if required to expand  the system CO line  capacity. •   located at  the  upper center  and oriented  in  a  vertical position,  the J4  cable  is  used to interface the DX-80 CPM. •   located at the upper  center  and oriented  in a vertical position,  the J5 cable  connects to  the standard APM4 installed  in KSU1. Each CO line circuit  incorporates  over-voltage  protection, ring  detector, loop  detector, loop/pulse-dial relay,  current sink circuit, coupling/isolation transformer (impedance  600:600), hybrid  circuit, CODEC & filter,  polarity guard  circuit  and Radio  Frequency noise filter. The  fourth CO line port is equipped with  CNG Fax  Tone  Detection circuitry.   When  programmed  as  a “FAX” line, this circuit will automatically engage the FAX Tone detector.  If FAX tone is detected, the system routes  the call  to the analog port  designated as the destination for  fax calls.

CPM

CPM (Central Processor Module) The  CPM module is equipped  standard  in  KSU1.   This board contains  all circuitry required to control the  fully  equipped  DX-80.   The  system  uses  the CPM to  perform all digital  voice switching and call processing  data switching. The  CPM has one ribbon  cable connector for connection  to the KSU1  408M and five  (5) connector sockets for connection of the system built-in modem,  voice processor,  and second  cabinet (KSU2).  Since  the CPM comes installed inside of KSU1 the CPM ribbon cable is already  in place and connected  to the KSU1-408M J5 socket.   Assuming the orientation of the  KSU1 cabinet is  installed on the wall; the  two horizontal connector  sockets in the upper  right corner  of the CPM are for  the MDM (Modem  Module).   The  connector socket labeled “2nd  Cabinet”  is for connection  to the KSU2-408E if that  expansion is  required.   The  remaining two connector sockets on the  CPM, one at the  left side, the other at  the right  side are for  the  voice processor  solution.   Note:   The  voice processor solution can be any of  three possible choices:  AAM,  7271C,  or 7270C.

Memory Module installation or replacement

Memory Module installation or replacement
Note: The Memory Module has a proprietary formatting scheme — do not attempt to install a non-ESI drive.
Contact ESI for a replacement Memory Module, if needed.
Adding or replacing the Memory Module will require that the ESI-100 be taken out of service.
All of the ESI-100’s configuration data and customer recordings are stored in the Memory Module.
Replacing it, therefore, requires re-programming and re-recording, unless you have previously performed a backup
using ESI System Programmer software. (Prompts stay intact, however.)
Note: Be sure to observe all proper procedures regarding the prevention of electrostatic discharge (ESD) when
performing the following procedures; otherwise, circuit boards may suffer damage.
Install the CompactFlash Memory Module
1. Open the lid of the cabinet (you must remove
the screw on the top that secures the lid).
2. Power down the system.
3. Plug the Memory Module into the J14 connector
on the main board (see diagram, right).
4. Secure the lid to the KSU

service code

: Service Code Setup (for System Administrator)  to customize the Service Codes for the System Administrator. You can customize additional Service Codes in Programs 11-11 ~ 11-16. The following chart shows: • The number of each code (01 ~ 50). • The function of the Service Code. • The type of telephones that can use the Service Code. • The default entry. For example, dialing item 26 allows users to force a trunk line to disconnect.

system numbering plan

System Numbering  to set the system numbering plan. The numbering plan assigns the first and second digits dialed and affects the digits an extension user must dial to access other extensions and features, such as service codes and trunk codes. If the default numbering plan does not meet the site requirements, use this program to tailor the system numbering to the site. Caution! Improperly programming this option can adversely affect system operation. Make sure you thoroughly understand the default numbering plan before proceeding. If you must change the standard numbering, use the chart for Table 2-1 System Numbering Default Settings on page  2-57  to keep careful and accurate records of your changes. Before changing your numbering plan, use PC Pro to make a backup copy of your system data. Changing the numbering plan consists of three steps: Step 1 : Enter the digit (s) you want to change You can make either single or two digit entries. In the Dialed Number column in the  Table 2-1 System Numbering Default Settings on page  2-57, the nX rows (e.g., 1X) are for single digit codes. The remaining rows (e.g., 11, 12, etc.) are for two digit codes. • Entering a single digit affects all the Dialed Number entries beginning with that digit. For example, entering 6 affects all number plan entries beginning with 6. The entries you make in step 2 and step 3 below affect the entire range of numbers beginning with 6. (For example, if you enter 3 in step 2 the entries affected are 600 ~ 699. If you enter 4 in step 2 below, the entries affected are 6000 ~ 6999.) • Entering two digits lets you define codes based on the first two digits a user dials. For example, entering 60 allows you to define the function of all codes beginning with 60. In the default program, only *  and # use 2-digit codes. All the other codes are single digit. If you enter a two digit code between 0 and 9, be sure to make separate entries for all the other two digit codes within the range as well. This is because in the default program all the two digit codes between 0 and 9 are undefined.

ACD departments

ACD department  programming ACD departments can be programmed  to  route calls based on several  optional  parameters.  Each  ACD station can  be  logged  onto  as  many as  two  ACD departments  at  the same  time.  Also,  each  ACD station  can be a  member  of  up  to  20  ACD departments  (i.e.,  up  to  20  log-on  keys may be  assigned  to  each  ACD  station.) Each  ACD agent  must  have  a Digital  Feature  Phone1, IP  Feature  Phone  II,  Digital Cordless  Handset, or VIP Softphone.  Agent log-on  keys  will  be  automatically  assigned  to  the  lower left  programmable  feature keys  for  the  stations listed in  ACD departments (with wrap  keys  automatically  assigned  above them;  see “Feature  keys,”  page  G.37).  Note:  Line keys  can’t  be used  to  answer  calls  ringing  Attend departments  set  in the live-ring list  (in Functions  211,  2121,  and 2131). ACD overflow Incoming calls  that  are holding  (queued)  for  an  available  agent  can be  automatically  forwarded  to  a new destination  if  ACD  overflow  is  assigned.  ACD  overflow  can be  initiated by  exceeding  a  maximum  number  of queued  calls  or  by  an individual  exit  timer  set  for  each  ACD department.  If  ACD overflow  parameters aren’t assigned,  the  default action  will be  to  overflow  calls  based  on  the  system  default  ACD  exit timer  only.   ACD overflow  parameters  are: •  Queue  exit  threshold  —  If  the number  of  calls  in  queue  matches a  predetermined queue exit threshold,  all  subsequent calls  to  that  ACD  department  will  immediately  follow  that  department’s   call-forward  destination. •  ACD exit  timer  —  When  a call  has been  held in  queue for  a  predetermined  duration  specified for  that ACD department, the  call will follow  the  department  call-forward  destination.  If the  department’s  ACD exit  timer  isn’t assigned,  the  system-wide  default  (for  the  current  operation)  will be  used. ACD agent  priority ACD  agents  who  are simultaneously  logged into  two  departments  can  have  calls  to  one department  take precedence  over  the  other  department’s  calls.  When  the  ACD station  is  assigned to  each  ACD department,  the “baseline”  priority  is  set  for  calls that  are directed to  that  station from  that  department. ACD call  escalation  (priority  override) An incoming  call  that  has  been  in  an  ACD department  queue the longest  can  be  forced  to  ring  at  the  next available agent,  regardless  of  the priority  setting  of  that  agent’s  station  department  log-in.  A timer  that’s  set  in  ACD department  programming (see  page  G.27)  triggers  this  ACD escalation.

Network Keep Alive Setup

Network Keep Alive Setup  to set the interval and retry count of the AspireNet networking keep alive message. The keep alive is used for ISDN and IP networking. The keep alive message is automatically responded to by the destination system, if the response is not received the retry count will start. If a response is not received within the number of retries, the networking link will be taken out of service. When the link is taken out of service: • Any calls that are in progress will be released. • Park Hold orbits will be released. • No further Park Hold information will be sent until the link is active. The link will automatically become active when the next keep alive response is received.

sip server

SIP Server Information Setup  to define the SIP Proxy setup for outbound/ inbound. The 10-29 commands are not used in non-registration mode.If entries are made in Program 10-29-xx for a SIP Server and the SIP Server is then removed or not used, the entries in Program 10-29-xx must be set back to their default settings. Even if 10-29-01 is set to 0 (off), the system still checks the settings in the remaining 10-29 programs.

Daylight Savings Setup

Daylight Savings Setup  to set the options for daylight savings. As the telephone system is used globally, these settings define when the system should automatically adjust for daylight savings as it applies to the region in which the system is installed

Pre-ringing

Pre-Ringing Setup  to enable or disable pre-ringing for trunk calls. This sets how a trunk initially rings a telephone. With pre-ringing, a burst of ringing occurs as soon as the trunk LED flashes. The call then continues ringing with the normal ring cadence cycle. Without pre-ringing, the call starts ringing only when the normal ring cadence cycle occurs. This may cause a ring delay, depending on when call detection occurs in reference to the ring cycle.

To enter programming mode

To enter programming mode : 1. Go to any working display telephone.In a newly installed system, use extension (port 1). 2. Do not lift the handset. 3. Press  Speaker. 4. # *  # *. 5. Dial the system password +  Hold. Refer to the following table for the default system passwords. To change the passwords,

PRI applications

T1/PRI For  T1 or  PRI  applications  (only  PRI on  the  ESI-50; it doesn’t support  T1),  an  ESI  Communications  Server can use a  compatible  digital  line  card  (DLC)1: •  ESI-1000,  ESI-600,  ESI-200,  ESI-100 —  DLC  and  DLC12,  each  for  either  T1  or  PRI. •  ESI-50  —  DLC82  for  only  PRI. Depending  on  how  you configure it,  each  supports  either  (a.)  a  single  T1 circuit  at  24  DS0 channels or  (b.)  a PRI  circuit  supporting  23  “B”  (bearer)  channels  and  one “D”  (data link)  channel.  The DLC12 and  DLC82 each also  support  12  digital  stations.  The  T1 or  PRI  line is  connected  via the  last  two pairs  of  the industry-standard 50-pin  amphenol  cable  connector  on  the front  of  the  DLC. Each  ESI  Communications  Server  has  a  different  maximum  number  of  system-wide  DLCs  (see  “Port  card options,”  page  A.4).  Partial  T1  or  PRI  applications  are supported  through  line  programming. Each DLC has built-in  CSU  functionality.  The  integrated  CSU  can be enabled  or  disabled  via system programming2.  The following functionality is  provided:  line,  payload,  DTE  and none  (normal  operation) loopback  modes  with  the  ability  to  respond  back  controlled  via  system  programming;  alarm  conditions,  and both  ANSI  T1.403  and  TR  54016  performance messages  for  ESF only.  Important:  On  the ESI-50,  the DLC82 may be installed in  only  slot  2. If  you’re  installing more  than one  T1  or  PRI,  the  DLC  in the lowest  number  slot  will synchronize (“slave”) the system  with  the public  network.  The system will  synchronize  to  only one clock  source.  Therefore,  ESI strongly  recommends  that  the first  DLC  in the  system be connected to  the  T1  or  PRI  that’s connected either  to  the local  CO  or  the nationwide long-distance provider,  either  of  which typically will provide  veryhigh-accuracy  clocking (Strata 3).  The DLC  doesn’t  provide master  or  sub-master  clocking for  privatenetwork  T1  spans.

ESI System Programmer

The  ESI  Communications  Server  supports  the  48-Key  IP  Feature  Phone  II,  ESI  IP  Cordless  Handsets,  VIP Softphone,  and  SIP  phones.  (See “System  capacities,”  page  B.1,  for  the maximum  number  of  IP  phones that your  specific  ESI Communications  Server  will  support.) The ESI-50 has  a built-in IVC12.  It  can  support  up to  12 IP  channels,  which can  be  a  combination of  local  IP, remote  IP,  and Esi-Link  channels.  The channels  are  activated in  blocks  of  four  for  local  IP,  singles for  remote IP,  and four  or  twelve  for  Esi-Link.  Here  is  an  example of  some  possible  ESI-50  IVC12 channel  combinations: •  12 all  Esi-Link. •  12  all local IP. •  Eight Esi-Link, four  local IP. •  Four  Esi-Link, four  local IP, four  remote  IP. When  two  or  more  Intelligent  VoIP  Cards  (IVCs)1  and the  necessary licensing are installed in  an  ESI Communications  Server, the  first IVC  (lowest-numbered  slot) will be  designated  as  the  primary  IVC,  which acts  as  a “go-between”  to  associate a  station to  its IVC.  To  each IVC,  the  system  automatically  allocates  24 sequential  extension  numbers,  as  defined  in  the  dial  plan selected  in  Function 169.2  Therefore,  the  primary  IVC must be connected  to  the  same  network  as  all  of  the  other  IVC  station cards. If  an IVC  supports  12  IP  stations,  only  the first  12  extension  numbers  can be  assigned to  IP  stations. Programming  IP  stations  is  similar  to  programming  digital  stations,  except  that  additional,  IP  networking parameters are required for  the former. There  are three ways  IP  networking parameters can  be assigned to  IP  stations in  an  ESI  Communications Server: •  Via  Function  31, as  described  in  the  following  pages. •  Using  ESI  System  Programmer. • Via “setup mode” at an ESI IP Feature Phone II.

Centrex

Centrex/PBX  access code If the  system  is  to  be  used  behind  Centrex  or  another PBX,  you  must  list  the  dial  access  code  used  to  gain access  to  a CO  line from  Centrex  or  the PBX,  so that  toll  restriction  can ignore  the  access  code  digit(s).  Users must  dial  the access  code  after  accessing  a line  by  either: (a.) Dialing 9, 8, 71, 72, 73, 74, 75, or 76.  or (b.)  Pressing  a  line key (if  programmed). The access  code can be one or  two digits  —  e.  g.,  9,  81,  etc.  —  and must  be programmed for  each line group. Default:  0.  Note:  You must  set  the flash duration in Function 151 (page  E.3)  for  the requirements  of  the host  switch. Function  222: Toll restriction exception tables The  system’s  toll  restriction  is  based  on  outbound  calls  being  defined  as  either  toll calls  (i.e.,  calls  in  the  deny table) or non-toll calls (calls in the allow table). Four tables exist for this purpose: 1.  Allow exception  table  (programmable).  Up to  100 entries;  no  entry  can exceed  26  digits. Default: No entries. 2.  Deny exception  table  (programmable).  Up to  100  entries;  no  entry  can exceed  26  digits. Default:  No  entries. A number listed  in  the  allow  exception  table  —  e.g.,  a  branch  office  or  vendor’s  location  —  will  be  allowed  to all  stations,  regardless  of  how they’re  set  in  Function  32  (see  page  G.19).  Conversely,  a number  listed  in  the deny exception table (e.g., a “1-900” number) will be denied to all stations. 3.  Fixed allow  table  (not  programmable). Default:  1800,  1888,  1877,  1866,  1855,  1844,  1833  and  1822.  4.  Fixed  deny  table (not  programmable). Default:  976,  1976,  1xxx976,  900,  1900,  1xxx900,  555,  1555,  1xxx555,  0,  10,  411,  1411  and   11+-digit  restriction. In  extension feature  authorization (Function  321;  see page  G.19),  each  extension is  set  to  be  toll-restricted one of  two  ways:  TOLL  CALLS = Y  (yes) or  TOLL  CALLS  = N  (no).

Background Music Description Background Music (BGM)

Background Music Description Background Music (BGM) sends music from a customer-provided music source to the Speakers of the Multiline Terminal when the station is idle.  Each 084M-B1 unit has 2 Audio In jacks on board and J431 (BGM) is used for BGM. As system can have 1 BGM input, effective BGM port needs to be determined at PRG 10-60-01. B Conditions • Background Music stops while the Multiline Terminal is in use. • Originating a call, answering a voice announcement, a ringing call, or internal paging interrupts Background Music. • Background Music is not available on Single Line Terminals. • Refer to Analog Communication Interface (ACI) for detail settings.

Repeat Redial

Sets how many times a Repeat Redial automatically repeats if the call does not go through. Default 3 02 03 04 Repeat Redial Interval Time Repeat Dial Calling Timer Time for Send Busy Tone for ISDN Trunk Conditions None 0 ~ 64800 seconds 0 ~ 64800 seconds 0 ~ 64800 seconds Set the time between Repeat Redial attempts. After dialing the trunk call, Repeat Redial maintains the call after this time. After this time, the system terminates the call, waits the Repeat Redial Time (Timer 02) and tries again. Sets the time (sec) to send out Busy Tone with an ISDN line, when called party is busy.

Connects up to six analog loop-start

CS-684, E2-684 — Connects up to six analog loop-start CO lines, eight Digital Feature Phones and four analog station ports. The CO line ports support standard CO and Centrex loop-start lines (but not ground-start CO lines). The analog ports provide a standard 24-volt, two-wire connection to fax machines, courtesy phones, modems, etc. Only one device can be connected to each analog station port. This card uses 12 station ports and six CO ports. • CS-612, E2-612 — Provides circuits to connect up to six analog loop-start CO lines and 12 Digital Feature Phones. Ground-start CO lines are not supported. This card uses 12 station ports and six CO ports. • CS-6ALC, ESI-6ALC — Similar to the CS-612 and E2-612, but connects only up to six analog loop-start CO lines (and no stations). • E2-A41 — Connects up to four analog devices (only), such as fax machines and cordless phones. This card uses four station ports and no CO ports. Each port provides a standard 24-volt, two-wire phone connection. Only one analog device can be connected to each port. • CS-A12, E2-A12 — Connects up to 12 analog devices (only), such as fax machines and cordless phones. This card uses 12 station ports and no CO ports. Each port provides a standard 24-volt, two-wire phone connection. Only one analog device can be connected to each port. • CS-D12, E2-D12 — Connects up to 12 Digital Feature Phones (only). This card uses 12 station ports and no CO ports. • CS-DLC12, E2-DLC12 (Digital Line Card) — Provides either a T1 interface supporting 24 DS0 channels and 12 digital stations or an ISDN PRI interface supporting 23 B (bearer) channels, one D (datalink) channel, and 12 digital stations.  A jumper on this card must be plugged onto pins 7 and 8 of J3 to enable ISDN PRI functions. Any (or all) of the available channels of the T1/PRI span (24 on T1, 23 on PRI) can be assigned, and the card supports loop-start, ground-start, E&M and DNIS/DID trunk types with immediate, wink-start or dial-tone-start signaling. This card is equipped with a built-in CSU that can be connected directly to a network interface unit, SmartJack, or ISDN PRI. Up to 12 Digital Feature Phones can be connected to the card.  All 24 CO ports are allocated (regardless of whether they are assigned or used). • CS-DLC, ESI-DLC — Similar to the CS-DLC12 and E2-DLC12, but supports only a T1 or PRI circuit (and  no phones). • CS-IVC, IVC (Intelligent VoIP Card) — Supports standards-compliant IP telephony service and features, including VoIP to the desktop and Esi-Link. It features highly configurable DSP technology that manages the flow of traffic among the port cards and converts IP packets into PCM (pulse-code modulation) traffic for transmission over the PSTN. The physical connection is a 10/100Base-T, RJ-45 Ethernet® interface that allows the system to connect to an IP-based local area network (LAN).  The IVC is offered in three versions:  •  IVC 24R — Provides 24 IP stations (local or remote).2  •  IVC 24EL — Provides 24 channels for Esi-Link.  •  IVC 12R12EL — Provides 12 IP stations (local or remote) and 12 Esi-Link channels; does not      support SIP phones.  Each ESI Communications Server model has a specific maximum of each type of IVC (see the table on page A.4). The system automatically designates the first IVC station card (lowest-numbered slot) as the primary IVC — which acts as the “master” that, when an IP Phone first comes on line, identifies the IVC station card to which the IP Phone connects (IVC Esi-Link cards are excluded from this operation). Licensing is required to support each IP Feature Phone or SIP phone. The following table shows the maximum number of IP Phones and Esi-Link channels for each system.

Toll Restriction enabled

Deny Restriction Table This option lets you program the Restrict Code Tables. If the system has Toll Restriction enabled, users cannot dial numbers listed in these tables. There are four Restrict Code Tables, with up to 60 entries in each table. The system restricts calls exactly as you enter the code. PBX Access Code Use this option to enter the PBX Access Code. When the system is behind a PBX, this is the code users dial to access a PBX trunk. Toll Restriction begins after the PBX access code. For PBX trunks (Program 14-04) the system only Toll Restricts calls that contain the access code. Always program this option when the system is behind a PBX, even if you don’t want to use Toll Restriction. PBX Access Codes can have up to two digits, using 0-9, #, *  and LINE KEY 1 (don’t care). When using Account Codes, do not use an asterisk in a PBX access code. Otherwise, after the Tables 1 ~ 4 = No Setting [caption: table] 1 ~ 4 (table) 1 ~ 60 (Entry) [caption: table] 1 ~ 4 Dial (Up to 12 digits) Dial (Up to two digits) Tables 1 ~ 4 = No Setting *, the trunk stops sending digits to the central office. Entries 1~4 correspond to the 4 PBX Access Codes. Each code can have up to two digits.

transfer calls

Use this option to prevent or allow extensions to Transfer calls to busy extensions. If disabled, calls transferred to busy extensions recall immediately. Use this option to enable or disable MOH on Transfer. If enabled (0), a transferred caller hears MOH while their call rings the destination extension. If disabled (1), a transferred caller hears ringback while their call rings the destination extension. Default 1 Related Program 1 (V1.5 Changed) 03 04 05 07 08 Delayed Call Forwarding Time Transfer Recall Time Message Wait Ring Interval Time Trunk-to-Trunk Transfer Release Warning Tone Delayed Transfer Time for all Department Groups 0 ~ 64800 seconds 0 ~ 64800 seconds 0 ~ 64800 seconds 0 ~ 64800 seconds 0 ~ 64800 seconds If activated at an extension, Delayed Call Forwarding occurs after this time. This also sets how long a Transferred call waits at an extension forwarded to Voice Mail before routing to the called extension mailbox. An unanswered transferred call recalls to the extension that initially transferred it after this time. For Single Line Telephones (SLTs) without message waiting lamps, this is the time between intermittent ringing. If this value is set to 0, the system rings once. Time starts when a trunk begins talking with another trunk (for example : trunk-to-trunk transfer, outgoing from trunk, Tandem Trunking). When this time expires, a warning tone is heard. If Program 24-02-10 is set, the conversation disconnects after time expires. This time is set again when the external digit timer expires. One of the trunks used must be an analog trunk (or leased line).

Mounting the cabinet(s) If wall-mounted

Mounting the cabinet(s) If  wall-mounted,  the  system  and  supporting  components  should  be  mounted to  a half-inch (or  thicker)   plywood  backboard.  To  wall-mount  a Base  Cabinet  or  Expansion Cabinet,  use the five  tabs  located at  the rear  of the cabinet.  The  center  tab has an enlarged  hole  and slot,  to  allow you  to  fix  the screw on  the  wall  before hanging the cabinet  onto  the  screw.  Once  you’ve  done  so,  fasten the  other  screws into  the four  remaining  holes to  finish  securing the  cabinet  onto  the wall. To  rack-mount  a Base  Cabinet  or  Expansion Cabinet,  use the forward-facing  screw  holes on  the  sides  of  the cabinet.  Only  two  screws  are  needed  per  side  (in  fact,  on  most  server  racks,  you  can’t  use  all  four  screws  on each side). Allow room  for  installation  of  the Expansion  Cabinet  either  now  or  in  the future;  the Expansion Cabinet  must  be installed  directly  below the Base  Cabinet.  Allow about  two inches  of  clearance  between the  units,  for  cabling.   Attach the  power  transformer  to  the wall  or  rack,  allowing  sufficient  length  in  both  cords to  reach the  power connector  on the front  side  of  the  cabinet  and to  reach a UPS  or  a dedicated  110  VAC outlet.

VRS/DISA

VRS/DISA One-Digit Code Attendant Setup  to set up single digit dialing through the VRS. This gives VRS callers single key access to extensions, the company operator, Department Calling Groups and Voice Mail. For each VRS message set to answer outside calls (refer to Programs 25-04 and 25-05), you specify: • The digit the VRS caller dials (0 ~ 9, *, #). Keep in mind that if you assign destinations to digits, outside callers cannot dial system extensions. • The destination reached (Maximum eight digits  ) when the caller dials the specified digit. The destination can be an extension, a Department Calling pilot number or the Voice Mail master number. A one-digit code can be assigned for each Automated Attendant message. Example: Message Number = 01, Destination = 2, Next Message Number = 0, Dial = 399 In this example, when 2 is dialed by an outside caller, the system transfers the call to 399. This means that extension 200~299 cannot receive calls from VRS/DISA users during/after VRS

transferred caller hears MOH

Use this option to prevent or allow extensions to Transfer calls to busy extensions. If disabled, calls transferred to busy extensions recall immediately. Use this option to enable or disable MOH on Transfer. If enabled (0), a transferred caller hears MOH while their call rings the destination extension. If disabled (1), a transferred caller hears ringback while their call rings the destination extension.

Universal answer

Universal Answer/Auto Answer  to assign trunk routes (set in Program 14-06) to extensions for Universal Answer. If the call ringing the paging system is in an extension assigned route, the user can dial the Universal Answer code (#0) to pick up the call. You can also use this program to let an extension user automatically answer trunk calls that ring other extensions (not their own). When the user lifts the handset, they automatically answer the ringing calls based on Trunk Group Routing programming (defined in Program 14-06). The extension user ringing calls, however, always have priority over calls ringing other co-worker extensions. Refer to the Line Preference feature in the  SL1100  Features and Specifications Manual for more information.

DID Translation Number Conversion

DID Translation Number Conversion  to specify for each Translation Table entry (800). • The digits received by the system (eight maximum) • The extension the system dials after translation (36 digits maximum) • The name that should show on the dialed extension display when it rings (12 characters maximum) • The Transfer Target - 1 and 2If the Transfer Targets are busy or receive no answer, those calls are transferred to the final transfer destination (Program 22-10). • Operation Mode Use the following chart when entering and editing text for names. Press the key once for the first character, twice for the second character, etc. For example, to enter a C, press 2 three times.

ISDN trunk

Enter the number of digits the table expects to receive from the Telco. Use this program to make the system compatible with 3- and 4-digit DID service. If ISDN trunks, we analyze the last digits that are set here. If it is T-1 or analog DID, it analyzes the first digits that are assigned here.

T1 service type

When connecting to T1 trunks, after changing Program 22-02-01 to match the Telco connected T1 service type, the T1 cable or the T1 unit must be unplugged and then reconnected for the T1 unit to sync. • When the trunk type is set to 3 (DID), the DID Transfer to Destination in 22-11-04 for each DID feature is not supported. This feature is supported only for DID trunks when assigned as VRS. • When the trunk type is set to 3 (DID), the DID Intercept Destination feature for each DID is not supported. This feature is supported only for DID trunks assigned as VRS.

Restriction

Use this option to set how the system Toll Restricts calls over PBX trunks. If you enable PBX Toll Restriction, the system begins Toll Restriction after the PBX access code. The user cannot dial a PBX extension. If you disable PBX Toll Restriction, the system only restricts calls that contain the PBX access code. The system does not restrict calls to PBX extensions. Refer to the PBX compatibility feature. Make sure Program 21-05-04 (Maximum Number of Digits Table Assignment) allows for PBX Toll Call Dialing (normally 12 digits). It chooses w

Trunk rout priority

Select the trunk based off the Trunk Route Priority (0) or based off the trunk that has not been used in the longest time (1). Default 0 Related Program 14-05 14-06 02 03 04 05 06 07 08 09 Intercom Interdigit Time Trunk Interdigit Time (External) Dial Tone Detection Time Disconnect Time when Dial Tone not Detected Dial Pause at First Digit Toll Restriction Override Time Preset Dial Display Hold Time Ringdown Extension Timer (Hotline Start) 0 ~ 64800 seconds 0 ~ 64800 seconds 0 ~ 64800 seconds 0 ~ 64800 seconds 0 ~ 64800 seconds 0 ~ 64800 seconds 0 ~ 64800 seconds 0 ~ 64800 seconds When placing Intercom calls, extension users must dial each digit in this time. The system waits for this time to expire before placing the call in a talk state (Call Timer starts after time expires, Voice Over and Barge-In is not allowed until after time expires). If dial tone detection is enabled, the system waits this time for the Telco to return dial tone. When the time expires, the system assumes dial tone is not present. To disable this time (and have the system wait continuously), enter 0. If 14-02-11 is enabled, the system skips over a trunk if dial tone is not detected. This option pertains to calls placed using Speed Dial, ARS, Last Number Redial or Save Number dialed. It does not pertain to line key or Direct Trunk Access calls. After dialing the Toll Restriction Override codes, the system removes Toll Restriction from the extension for this time. A Ringdown extension automatically calls its programmed destination after this time.

ESI Cordless Handset

To  achieve  optimum  operation  from  your  ESI  Cordless  Handset  II Repeater: •  Place  the  Repeater  at  least  six feet  off  the ground so it  has a clear  line-of-sight. •  Make sure  the Repeater  has  good  reception from  the  base  station (or  Repeater  to  which it  is   daisy-chained). •  Make sure  the Repeater  location  is  close to  a  standard 120  VAC power  outlet. •  Never install  electrical  cords across  traffic  areas  where they  can cause a tripping  hazard  (additionally, such cords,  if  damaged,  may create  fire  or  electrical  hazards). •  Allow  at  least  35  feet  between Repeaters. If you  install Repeaters  across  multiple  floors, be  sure  to  allow  35 feet  vertically, too. •  Install  the Repeater  away from  sources of  electrical  interference.  Examples include  audio systems, office equipment,  and microwave ovens. •  Install  the Repeater  away from  heat  sources  and  direct  sunlight. •  Install  the Repeater  away from  items that  can interfere with  radio signals.  Examples  include  metal doors,  thick walls,  niches,  and cupboards.

base station

Installing ESI’s Cordless Handsets Note:  Except  where noted,  this  section applies  to  both the  ESI  Cordless  Handset  II  and original ESI  Cordless Handset  models. Each ESI  Cordless Handset  comes with: • A charger/cradle  to  charge the  Handset. • An  AC  adapter  for  use  with  only  the  charger. • A base station  to  provide  a  digital  interface between  the  ESI  phone system  and  ESI  Cordless Handset.  This  base  station  needs  no  AC  power: if the  Cordless  Handset  is  digital,  the  base  station is  line-powered;  if the  Cordless  Handset is  IP,  the  base  station  uses  Power  over  Ethernet  (PoE). •  Wall-mount(s),  a  belt clip,  and a  Quick Reference  Guide. Each  ESI  Cordless  Handset  is  keyed to  only  one  base  station  and takes  up  one  port  (digital  or  IP)  on  a  port  card. Base station  installation Due  to  each  site’s  unique  characteristics,  the  range  and  distance  information  we’ll provide  herein  is   only approximate. Characteristics that  positively  affect  performance: •  The base  station  should  be  installed so  it  has a  clear  line-of-sight  with  the Cordless  Handset. •  The  base  station antenna should  always  be  pointed  in  its uppermost  vertical  position. Characteristics that  negatively  affect  performance: •  Large amounts  of  metal  shelving  (such as  in  manufacturing or  warehouse areas). •  Close  proximity to  (within  one mile  of)  a radio tower. •  Concrete  walls that  divide  spaces  where  Cordless  Handsets  are used  (assuming the base  stations  are in one location). Don’t  install  the  base  station: •  Close  to  a wall  with  metal  studs. •  On  a  metal wall. •  Next  to  a  device  that  emits  RFI  or  EMI1  —  e.g.,  a television,  radio,  computer,  computer  printer,   fluorescent  light  fixture,  or  fax machine. •  Next  to  any other  900 MHz  device  —  e.g.,  a  hand-held inventory control  device. •  In  a  ceiling  that  has  foil-backed  insulation. •  Behind  doors that  typically are closed,  tinted  windows,  one-way glass,  or  other  areas  that  limit  or   cut  off transmission  to  the  Cordless  Handset. Base  stations must  be  installed  at  least  10  feet  apart,  regardless  of  whether  the base  station is  for  the  small-model  or  large-model  Cordless  Handset.  Don’t  install  more  than  six base  stations  in  one  area   (such  as  a  network  room).  Choose  a location  at  least  30  feet  away  if  more  than  six  base  stations  are needed in a building.
