PBX / Centrex Compatibility

Description

The DSX provides unique features when connected to a PBX or Centrex.

PBX/Centrex Access Codes

PBX Access Codes are the digits PBX extension users must dial to obtain outside lines. When the DSX is installed behind a PBX, users must dial these codes before the digits for their outside call. For example, if the PBX access code is 98, and the DSX user wants to reach 203-926-5400, they must dial 98-1-203-926- 5400. Normally, DSX Toll Restriction and Forced Account Codes are applied to the digits dialed after the PBX Access Code. This is because any call dialed without the PBX access code is an internal PBX call, and usually won’t require the restrictions imposed by Forced Account Codes and Toll Restriction.

To keep track of valid PBX Access Codes, DSX allows you to enter up to 10 PBX access codes in the PBX Access Codes Table. Each code is either 1 or 2 digits long, using the digits 0-9 and #. You can use the * char- acter as a wild card, which can be entered in any position in the PBX Access Codes Table. A wild card allows the user to dial any digit in that position. For example, the entry 7* represents entries 70, 71, 72, etc.

In addition to entering codes in the PBX Access Codes Table, you must also indicate in programming which DSX lines are PBX lines (i.e., connected to the PBX - not the Central Office).

PBX/Centrex Access Codes and Toll Restriction

The following occurs if a DSX line is programmed as a PBX line and access codes are properly entered in the PBX Access Codes Table (see Programming below):

❥If an extension user seizes the line and dials a number without a valid PBX access code, DSX assumes the call is an internal PBX call and allows it without restriction.

❥If an extension user seizes the line and dials a number preceded by a valid PBX access code, DSX enforces Toll Restriction based on the digits following the PBX access code.

PBX/Centrex Access Codes and Account Codes

Forced Account Codes for All Calls

If Forced Account Codes for All Calls is enabled, and Forced Account Codes are enabled for the line, the system always requires Account Code entry on PBX lines.

Forced Account Codes for Toll Calls Only

If Forced Account Codes for Toll Calls Only is enabled, the line is programmed as a PBX line, access codes are properly entered in the PBX Access Codes Table, and Forced Account Codes are enabled for the line:

❥If an extension user:

-Seizes the line.

-Dials a number without a valid PBX access code.

DSX assumes the call is an internal PBX call and does not require the user to enter an Account Code for the call.

If 1551-04: Account Code Toll Restriction Level = 1-7

❥If an extension user:

-Seizes the line,

-Dials a valid PBX Access Code,

-Dials a number restricted by the Toll Level specified, DSX requires the user to enter an Account Code for the call.
