Chapter 3. System Features
Centrex/PBX Compatibility
(CPC-A Version 3.2 or higher, CPC-AII, and CPC-B Version 2.1 or higher)
Description
Centrex/PBX Compatibility allows the DBS to be connected to centrex or
PBX lines.
The DBS supports up to 8 access codes for dialing centrex or a PBX. These
access codes allow the DBS SMDR output to exclude the number dialed to
reach a centrex or PBX line.
The DBS also supports transmission of a flash signal over the centrex or PBX
link.

• FF2 (Trunks): Trunk Type
• FF8 (Least Cost Routing): LCR Add Tables
Considerations
• The LCR Add Table can be used to prefix digits for outgoing calls through
Direct Inward Dialing (DID)
(CPC-B Version 2.0 or higher)
Description
The Direct Inward Dialing (DID) feature allows an extension to have a
dedicated direct number. The dedicated number allows calls to be made
directly to the extension, without the caller going through the attendant.
Prior to CPC-B Version 3.1, only one DID number could be assigned to an
extension. Beginning with CPC-B Version 3.1, one DID number can be
assigned to several extensions, and one extension can have more than one
DID number; this is also true of CPC-AII.
If a DID number is assigned to more than one extension, incoming calls to the
DID number ring at all the assigned extensions simultaneously.
