Cordless handset

ESI  Cordless Handset II Repeater The  optional  ESI  Cordless Handset  II  Repeater  extends the  coverage  area  of  the ESI  Cordless  Handset  II  in all  directions,  including up and down. If  Repeaters  are installed  so their  coverage  area  overlaps  that  of  the base  station,  the base  station  can  hand off  calls to  the  Repeaters  as the  user  moves from  one  coverage  area to  another.  When it’s  connected to  a Repeater,  the ESI  Cordless  Handset  II  operates  exactly  as  it  does  when  connected to  its base  station,  and the  handoff  from  the base  station to  the  Repeater  occurs  seamlessly  without  disturbing the  end  user,  even during an active  call. Each ESI  Cordless Handset  II  base  station supports  up  to  six  repeaters,  regardless  of  configuration. •  Each  Repeater  supports  up  to  two  direct  connections  to  other  Repeaters. •  No  Repeater  can  be  more  than  three  connections  —  or  hops  —  from  the base  station. All  Repeaters,  regardless  of  configuration,  must  be registered  to  the base  station. Repeaters  that  are registered  directly  to  a  base station  (left),  do  not  require  use  of  the optional Repeater  Configurator  Kit. These  Repeaters can be  installed  using automatic configuration. However,  Repeaters registered to  the base station  through  another  Repeater  (one example shown,  right)  do  require use of  the Repeater  Configurator  Kit. For  detailed information  on installing  Repeaters,  refer  to  the  ESI  Cordless  Handset II Repeater  Installation  Manual  (ESI  # 0450-1248).

call on a PRI

Every  call  on  a  PRI  span  is  sent  with  the  called  number  in  the setup message.  This  means you can  determine whether  to  use a  number  as  a pilot  number  or  as  a DID  number.  Pilot  numbers  are  a means  of  routing  a company’s primary  published phone  number  differently  from  a  DID.  Each  ESI  Communications  Server  has  a different  capacity  for  pilot  entries,  each  with  its  own answer  ring  assignment;  see “Translation tables”  in “System  capacities”  (page  B.1).  This  is  important,  because the  dynamic  channel  allocation  prevents  you from routing based on channel. Pilot  numbers can  be  routed  to  an  ID  branch,  department,  extension or  mailbox.  This  varies  from  DIDs  in  that, when a  DID number  is  routed  to  an  extension,  it  is  considered answered and  follows  the  busy/ no-answer routing  of  the  extension;  but,  with  pilot numbers,  the  call  will be  routed  to  the  extensions  for  live  answer  for  the designated  number  of  rings,  then can  be  routed  to  an  ID  branch  in  the  event  of busy/no-answer.  If  the  PRI  span is  used  for  outgoing calls,  pilot  table entry  1  is  used  for  outgoing  Caller  ID,  as  well.  Because of  this,  pilot number  entry  1 should  always be  programmed  with  10 digits.

PBX using standard loop-start lines

CO  lines An  ESI  Communications Server  can operate either  on  a station-by-station  basis as a  PBX or  as  a combined key/PBX  using standard loop-start  lines.  If  a  station has  line  keys  programmed,  the  user  accesses  the lines  by pressing  one  of  these  keys  or  by dialing  the  line group number  9  (or  8  or  71–76).  If  a  station does  not  have line keys  programmed,  the  user  always  accesses  CO  lines by dialing  9  (or  8  or  71–76).  Since the  system  handles call  transfer  and  auto  attendant  functions  efficiently,  operating  in  the PBX mode  provides  more  programmable feature keys  for  other  uses and  the opportunity  for  glare is  greatly  reduced.  Notes:  When  a  port  card  is  added  to  or  removed  from  the  system  —  i.e., thus  changing  the  number  and configuration  of  cards  in  the system  —  you must  reprogram the CO  lines.  However, if  a  port  card  is replaced by  the  same  type of  port  card  (e.g.,  when you replace a faulty  684 card  with  a new  684 card1), you don’t  have  to  reprogram the CO  lines. As  a  visual indication of  CO  line usage,  the phone’s  display will  show  on/off-hook  line status. All phone programmable keys  default  to  being unprogrammed (except  on extension 100,  where the first  key defaults  as a day/night  key).  Use  extension button mapping  (Function 35;  see page  G.36)  to  assign line keys  system-wide.  An  individual station’s  keys  can be reassigned using  either  PROGRAM  2  or  “radio-key programming”  at  that  station.

system structure

manual provides  information for completely programming  a  new  DX-80 system  from  scratch.  Comdial  also provides  you with  some  tools you can use to reduce your  programming time.   These tools include: •   a  series of worksheets for  you to plan your system structure,  and record the programming for future reference if  necessary.   For more details,  see Appendix A,  Worksheets. •   copying  a  base  CO line or  extension’s setups  to several  other  CO  line or extensions thereby eliminating the  need to program them individually,  and •  using one of four standard database programming templates provided  with the DX-80 on CD part number DX80UTILCD.   You can  choose the template that most  closely matches your  new customer’s  site  needs,  and then add  whatever custom  changes  you need to make.   This  approach saves you the time  of programming the entire system from scratch. For  more  information on these and  other aids  the DX-80  provides  to allow you to program  a  system efficiently,  see  Section 3.1,  Shortcuts to  Help  You  Work Faster. When  you  are programming  a  new system from  scratch, perform the following basic tasks: 1.  Set  up  the system  features. 2.  Set  up  the CO lines. 3.  Set  up  call handling. 4.  Set  up  the toll restrictions. 5.  Set  up  the UCD groups. 6.  Set  up  Voice Mail  (if applicable).

fifo

Use this option to enable or disable themailbox. An extension mailbox is not ac-cessible when it is disabled (even thoughits stored messages and configuration areretained in memory.) If disabled, a userpressing Message initiates a remote logonand is asked to enter their mailbox num-ber. A voice prompt then announces: “Thatmailbox does not exist.”To make programming easier, considerassociating a mailbox number with a sta-tion port. For example, mailbox 1 couldcorrespond to port 1, which in turn corre-sponds to extension 101.Mailbox 1 ~ 64 :1Mailbox 65 ~ : 002Mailbox NumberUp to eight digitsUse this option to select the extensionnumber associated with the mailbox youare programming. Normally, mailbox 1should use Mailbox Number 101, mailbox2 should use Mailbox Number 201, 101etc.To make programming easier, considerassociating a mailbox number with a sta-tion port.

repeater installation

Repeater  installation  notes 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. In case of trouble If  you have  followed  the  guidelines  described herein  and  still  encounter  problems with  ESI  Cordless  Handsets, please  call  ESI  Technical  Support  at  800 491-3609  or  e-mail to  techsupp@esi-estech.com.  When  contacting ESI  Technical  Support,  be  sure  to  have  as  much  of  the following site  and  usage  information as  possible: •  Square footage  of  the  building. •  Layout  of  building/offices,  and locations  of  base  stations  and repeaters.  This  can  be  a  hand-drawn diagram  with  locations  of  base  stations (you  can fax it  to  ESI  at  972 422-9705; be  sure  to  indicate  that  it goes to  Technical  Support).  The  objective is  to  give the  ESI  technician  an idea  of  the site’s  layout. •  Number of  Cordless  Handsets,  whether  they  are  Cordless  Handsets  II  or  original  Cordless  Handsets,  and how  many  are  of  each type (digital,  Local  IP,  or  Remote  IP). •  How the troublesome Cordless  Handset  is  being  used.  For  example,  is  it  used  by  a  supervisor  who travels the  entire area  of  the  building many times per  day,  or  by an  administrative  assistant  to  go  a  short  distance from  an  office  to  a  copy  room? •  Where the problem  occurs  —  e.g.,  if  a  Cordless Handset  cuts  in  and out  when used  in  a certain area  of the building.

External DT

If this option is set to  0, the F-Route table selected is determined only by the digits dialed without any relation to the day or time of the call. If this option is set to  1, the system first refers to PRG 44-10. If there is a match, the pattern defined in that program is used. If not, the F-Route pattern in PRG 44-09 and time setting in 44-08 are used. 02 03 Dial Tone Simulation (V2.0 Added) Tone Kind  (V2.0 Added) Conditions None 1 digit (0 ~ 9) *, # cant be used 0 = Internal DT 1 = External DT When first dialed digit matches with the data set in this Program, system send simulated DT to calling party after receiving first digit. Numbering plan for the dial needs to configure as F-Route at PRG 11-01. Set simulated DT kind which can change the tone used at PRG 44-01-02 and PRG 44-02-04.

PRI local number

PRI  local  number  digit  length Tells  the  system  whether  there is  seven- or  10-digit  local  dialing in  the  system’s  area.  If  the local  calling area  uses  only  seven-digit  dialing,  set  this  value to  7  (this tells  the  system  not  to  wait  for  additional  digits when  a local  seven-digit  number  is  dialed). Range: 7 or  10.  Default:  10  (supports  both 10- and  seven-digit  dialing). Field 8:  Dialing off-hold Enables  or  disables  outside  callers’  ability  to  dial  off-hold  only  when  MOH  590  (external  source) is selected.  When this  is  enabled, CO  callers  will  be  able  to  dial  extension,  department,  and  mailbox numbers while on  hold.  When this  is  disabled, the  system  will ignore  digits  dialed  by  CO  callers.  To enable  or  disable outside callers’  ability  to  dial  off-hold,  press a  scroll  key to  make the desired selection and then  press  #  to  confirm. Default:  Enabled. Field  9:  Re-sending  of  Caller  ID  in  Intelligent  Call Forwarding This  parameter  “turns  off”  the repeat  Caller  ID  (re-sending)  component  of  Intelligent  Call  Forwarding. Some  service providers  —  local  exchange  carriers  or  inter-exchange  carriers  —  don’t  allow repeating the caller’s  CID  data when making  an  outgoing  call. If re-sending  of  Caller ID  is  disabled, the  PRI  pilot number  of  the  station’s  tenant will  be  sent  instead. If re-sending  of  Caller ID  is  enabled,  CO  calls that  are forwarded to  an  off-premises  number  over  a  PRI channel will  send  the  original  caller’s  CID  data  to  the  called  person.  To  enable or  disable this  parameter, press a scroll  key  to  make  the  desired selection and  then  press  #  to  confirm. Default:  Enabled.

Installation overview

Installation Overview The  following  steps provide  an  overview  of the  installation process.   Details  on each of these  steps  are contained in  the  following  sections of  this chapter.   Be sure to read  the detailed instructions  before installing the  DX-80. 1. Plan the  installation, including  the KSU1 or  KSU1  and KSU2 and  Main Distribution Frame (MDF) location, station  locations,  cable runs,  and optional equipment. 2. Assemble  the correct tools  and supplies: UTP  telephony grade cable/wiring, miscellaneous telephony  hardware,  66  blocks, modular wall jacks, etc.) 3. Run the  wiring  for speakerphones, DSS consoles and analog devices (FAX  machines, modems, etc.)  from the MDF  to  each location.   Wiring  topology  is referred  to  as  “star-wiring”  configuration; no  cable should loop  from  one telephone location to another. 4. Run cable/wiring to any  optional  equipment, such as external  paging  equipment,  loud  bell signaling devices, music sources, etc. 5. Mount the  MDF backboard and attach the  terminal  blocks  on the backboard.  Use a  dedicated MDF with  66 block wiring field to  promote full serviceability of  the system  and connections using  proven  techniques.   If you  route  extension  cables into the  KSU, you  have to terminate one cable  pair into standard crimping  modular connectors for  each cable.

RAD devices individually

Setting Up UCD Voice Announce (VA) Groups The  DX-80 system provides UCD groups  to  allow you  to  handle  high  traffic using third-party ancillary RADs.  Whenever the overflow destinations  of a  UCD group  require you to use more than  one RAD to handle the volume of call traffic, you can pool the  RADs  in a  group (available UCD  group) for  access.  If you do this, any of the available devices can handle  waiting calls with the same announcement. The following  conditions apply. •   You must  assign all voice announce  UCD group members to port type V.A. •   You  must  record all ancillary  RAD  devices  individually  for the same announcement. These conditions do not  apply when  using the DX-80 VP system  for  UCD Overflow announcements. 8.4.1  PROGRAMMING USING THE DET Note:  chg,  bksp,  save,  one,  always,  del,  and  ack  are interactive LCD button  operations.  Use  the three buttons below the LCD display  to  actuate  the associated  operation. 1. Enter Database Administration  using  the feature code  Feature # *  and then enter  the DB  Admin password. 2. Press  show.   The system displays the DB Item Select  screen. 3. First, program  the analog extension ports as type  V.A. 4. Enter  01-nnn-21, then press  save  (where “nnn” is the extension  number  of the  analog  port connected to  an ancillary RAD Device).  This advances you  to the selected  extension Port Type field. 5. Press  chg  to  select VA.

DSS

DSS (Direct Station Selection) Console The DSS console is a digitally interfaced component  of the DX-80.   It  connects to the  system via any available digital  port  (408M/E  or DPM8  digital  port).  The  DSS is equipped  with 60 programmable buttons.   Twelve  of these buttons  are  intended  for features  code  storage  only  and do  not have LED indications  associated  with them.   Forty  eight buttons  are equipped with dual  color (red /  green) LEDs and may be assigned any  system  feature code  or directory number; these buttons may be  assigned  for either  system  features  operations or CO  line access operations. You can  mount  the  DSS  console in one  of  two positions:  lower profile  desk  position and  wall mounted position.   DSS consoles  are programmed to  operate with  an associated  speakerphone.  You  can assign up  to four  DSS  consoles  per  speakerphone.  The maximum  number of DSS consoles supported by  the DX-80  is  12.   Each  equipped  DSS  console  requires  one digital  port, therefore  the total  number (system capacity) of speakerphones  possible is reduced by one for  each DSS console

CO line connection Note:  For  greatest  simplicity,  this  section mentions  each  port  card  without  the use of  an “ESI,”  “E2-,“  or  “CS-“ prefix,  as  cards  otherwise  are  functionally  identical  —  e.g.,  we  refer  to  an  E2-684  or  CS-684  as  just  a  “684.” Local  loop An ESI  Communication  Server’s  advanced  CO  line  circuitry provides  for open loop  detection  and the system’s  built-in  Caller  ID  interface.  Loop  start  lines  are  connected via  the  last  6  pairs  on each  66  block  on  the 612 and 684  cards.  Note:  Observe  correct  order  of  connection to  preserve  proper  rotary  hunting  of  the CO  lines. 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.
