GCA40–112 DXP General Description
46 – Understanding The Features
6.2 Defining The Features
The following section defines all of the DXP features. Read through all of these definitions before
programming the DXP to ensure that you are programming the desired feature.
Abandoned Hold Release
If a distant on-hold party hangs up, it may cause an interruption in the line current. The DXP system then
drops the line from the hold condition and returns it to service. You can program the time interval
between hang-up and line-drop with choices of either 50 milliseconds or 350 milliseconds. The central
office makes the arrangement for the time choice. Also refer to the discussion titled, Disconnect
Access Denied

Comdial DXP

If you have programmed the system to do so, it can deny access to particular lines and group intercoms at
certain telephones. A user cannot select a line for use if it is access denied at his or her telephone.
Account Code Button
As part of the button mapping, the system installer can assign a special button that the user may use to
apply an account code to a call. Refer to the discussion titled Account Codes With Positive Verification.
Account Codes With Positive Verification
Station users can assign account codes to specific calls. The system uses the account codes to identify
calls by category, or special grouping, for call accounting purposes. All calls with the same account code
are reported together by the station message detail accounting (SMDA) feature. The system attendant can
obtain a separate printout of calls assigned to one account without causing any other calls to print or be
deleted. The programmer can arrange for the system to verify that the user entered an account code and
to sound an error tone if an invalid account code is entered. If the programmer arranges it, attendants can
use account codes as a basis for SMDA print-outs. He or she may program the system to prompt station
users to enter account codes for incoming calls and/or out-going calls if desired. The prompt can be with
or without system verification of the entry. Alternately, account code prompting can be turned off
completely. Depending upon the type of call, different users are associated with the call accounting
record. The following list explains to whom the call record is associated:
• On out-going calls, the user who enters the account code
• On transferred calls, the transferee
• On incoming calls, the last user active on a call.
Account codes may be from three to 16 digits in length as set by class of service programming. The
system will verify all digits. Also refer to the discussion titled Account Codes With Positive
