8. PBX, Centrex & ISDN
8.1 Access PBX or Centrex
The iPECS has been designed to operate with a host
PBX system or Centrex services from your service
provider. The iPECS 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 iPECS 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.
8.2 Access the ISDN Network
8.2.1 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. Once active, dial
into the ISDN for services; however, actions other than
dialing will deactivate the Keypad Facility operation.
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:
• Press the FLASH button
• After receiving new dial tone, dial PBX/Centrex feature code.
To activate Keypad Facility operation:
• Press the KEYPAD FACILITY button to switch to keypad mode,
• Dial as desired.
