9. PBX, CENTREX & ISDN FEATURES
9.1 Access PBX or Centrex features
The iPECS system has been designed to operate with a host
PBX system or Centrex services from your service provider. The
iPECS system connects to a host with analog CO lines.
When accessing a CO line, the phone will act as an extension of
the host, allowing access to the host system features using the
host dial codes. While on a call, use the Flash feature to
transfer calls to other host extensions or access features of the
host. The Flash feature may be used on other CO lines to regain
dial tone from the CO line without relinquishing control of the CO
line to place another call.
To access PBX or Centrex features while idle:
• Lift the handset,
• Select/dial access a PBX/Centrex CO
line,
• Dial PBX/Centrex feature code.
To access PBX/Centrex features while on a PBX/Centrex
CO line:
• Select the Flash soft button or the FLASH button, in case of
LDP-9208D, make {Flash} as Flexible button (Code is 94),
• After receiving new dial tone, dial the PBX/Centrex feature
code.
9.2 Access the ISDN Network
9.2.1 Using the Keypad facility to access ISDN features
Access to certain features of your ISDN services requires that
dialed digits be sent to the ISDN as data and not tones. In this
case, dialed digits are sent as ‘Keypad messages’.
A Keypad Facility button must be assigned using the Flex
Button program procedures (the code is 89). Once active,
dial into the ISDN for services; however, actions other than
dialing will deactivate the Keypad Facility operation.
To activate Keypad Facility operation:
• Press the KEYPAD FACILITY button to switch to keypad mode,
• Dial as desired.
