Installing ESI handsets

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.

T1/PRI

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.

Group listen

Group listen enable/disable With  this  feature  disabled:  if  a station  user  presses  SPEAKER  while on  a  call,  the Feature Phone immediately  turns off  the  handset  and switches  to  hands-free mode. If  enabled,  the group listen  feature is  available  system-wide.  If  disabled,  it  is  no  longer  available. Default:  Disabled. Field  2:  Privacy  release  enable/disable With  this  feature  enabled:  if  a  station user  presses a  CO  line  key that  is  in  use (lit  red),  the user  will  be immediately  conferenced with  the  call  in  progress  on that  line.  With  this  feature  disabled:  pressing  an  in-use CO line  key has  no  effect. Default:  Disabled.

Grounding instructions

Grounding instructions System grounding (supplemental ground) is as follows: • The conductor wires can be no smaller than the ungrounded branch-circuit supply conductors (usually 16-gauge or higher). • Acceptable wire: bare or covered with green (or green-and-yellow-striped) jacket. • Conductors (and power receptacles) shall connect to earth ground at the service equipment (usually a cold water pipe or copper ground rod). • The supplemental ground must: be used regardless of power cord ground, be connected to the ground lug on the bottom of the cabinet, and retain ground connection when the power supply module is unplugged. • Connect the grounding lugs of all units to system ground 

Mirroring

Mirroring operation On system  power-up  —  e.g.,  at  initial  installation or  whenever  a  drive  is  replaced  —  the  M3  will  first  verify  that each  drive is  an  ESI-formatted  drive.  If  so,  it  then  will  transfer  all  data  from  the primary  drive to  the mirroring drive.  This  process  can take  anywhere from  a few minutes to  one  hour,  depending  on  system  activity,  amount of  voice message  storage,  and  configuration.  System  operation  won’t  be affected during  the  data  transfer, because  this  transfer  will  occur only  when  call-processing  is  making  no  disk  drive  access  requests. If a  primary  drive  is  replaced, data  will be  copied  in  the  same  fashion  from  the  mirror  drive  to  the  new  primary drive.  Again,  the replacement  drive must  be  a new,  unprogrammed ESI  drive.  If it’s  not, the  system  may copy  all  data in  the wrong  direction  —  i.e.,  from  the  new (mostly empty)  primary  drive to  the mirror  drive! Therefore,  ESI  recommends that  the  mirror  drive be  moved  to  the  primary  drive  mounting position and  the new drive be  mounted on  the  mirror  drive mounting position.

CO line telephone numbers,

Registration The CO  line  telephone  numbers,  FCC registration  number,  and ringer  equivalence  number  (REN)  of  this equipment  must  be  provided  to  the telephone  company  before  installation.  (See  below for  FCC registration number and ringer equivalence number.) FCC Part  15 This  equipment  has  been  tested  and  found  to  comply  with  the  limits  for  a  Class  A  digital device, pursuant  to Part  15  of  the FCC Rules.  These limits  are  designed to  provide  reasonable  protection  against  harmful interference  when  the  equipment  is  operated  in  a  commercial  environment.  This  equipment  generates,  uses and can radiate radio frequency energy  and  —  if  not  installed  and  used  in  accordance  with  the instruction manual  — may cause harmful  interference  to  radio  communications  (in  which case,  the  user  will  be  required to correct the interference at his/her own expense). FCC Part  68 This  equipment  complies  with  Part 68  of  the  FCC  Rules.  On  the  bottom  of  this  equipment is  a  label that contains,  among  other  information,  the FCC Registration Number  and  Ringer  Equivalence Number  (REN)  for this  equipment.  You must,  upon request,  provide this  information to  your  telephone  company.  The  REN  is  helpful to  determine  the  quantity  of  devices  you  say  connect  to  your  telephone  line  and  still  have all  of  those devices ring  when  your  telephone  number  is  called.  In  most,  but  not  all,  areas,  the  sum  of  the RENs  of  all  devices  connected to  one line  should  not  exceed  five (5.0).  To  be certain of  the  number  of devices you may  connect  to  your  line,  as  determined by  the  REN,  you  should  contact  your  local  telephone company to  determine the  maximum  REN for  your  calling area. If  your  telephone  equipment  causes  harm  to  the telephone  network,  the telephone  company  may discontinue your  service temporarily.  If  possible,  the telephone  company  will  notify  you in  advance but,  if  advance  notice is  not practical,  you  will  be  notified  as  soon  as  possible.  You  will be  informed  of  your  right  to  file  a  complaint with  the  FCC. Your  telephone  company  may  make  changes  to  its  facilities,  equipment,  operations  or  procedures  that  could affect  the  proper  functioning  of  your  equipment. If  so,  you  will be  notified  in  advance,  to  give  you  an opportunity  to  maintain  uninterrupted  telephone  service. If  you experience trouble with  this  telephone  equipment,  the telephone  company may ask that  you  disconnect  this  equipment  from  the network  until  the problem  has  been  corrected  or  until  you are  sure  that  the equipment is  not  malfunctioning. This  equipment  may not  be  used  on  coin  service provided  by the telephone  company.  Connection to  party lines  is  subject to  state  tariffs. Installation:  The  device  is  equipped  with  a  USOC  connector. Registration Number:   1T1MF08B33727. Ringer equivalence number (REN):  0.8 Hearing-aid  compatibility This  equipment,  utilizing telephone  station equipment  manufactured  by  ESI,  meets all  FCC requirements for  hearing-aid compatibility.

Repeater

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.
