Programming The System For ISDN–PRI Application
To arrange the DXP Plus system for ISDN–PRI operation, you must take the following programming actions:
•
Use Board Configuration programming to program the ISDN service features.
•
Use Line programming to make every ISDN line a PRI B Channel line type and make the DID/DNIS
programming choices.
•
Use Line Group programming to group together the lines that correspond to the T1/PRI channels.
•
Use Station programming menu to program the specific ISDN requirements in addition to the other station
programming needs.
•
Use Button Mapping programming to map a restrict button on the ISDN station.
•
Use Features Numbering to add dialing codes for two ISDN-specific features.
Board Configuration
When you add a T1/PRI board in a common equipment cabinet board slot, that slot becomes programmable, and
you can make several programming choices that affect ISDN–PRI service.
Protocol—With the Protocol feature, match the software to the central office (CO) switch type. The switch types
that the software supports include the following items:
4ESS (AT&T* 4ESS switch protocol)
5ESS (AT&T* 5ESS switch protocol)
DMS100 (Northern Telecom** DMS100 switch protocol)
* Lucent Technologies, Murray Hill, NJ 07974
**Northern Telecom Limited, Richardson TX 75082
Default Number—This feature allows you to select a default value for the Calling Number ID. The system uses
this number to identify the calling party in the following cases: when you use the Calling Number ID Mode
feature to specify board level identification, when you do not program a calling number identification for a station
(see Station Programming for details), and when the call is a line-to-line call through the system.
Calling Number ID Mode—This feature allows you to set calling number identification at either a board level or
a station level. The selections include the following choices:
Default Number (selects board level identification such as the company’s main number)
Station Number (selects station level identification—requires that you program the Outbound
Calling Number ID and Station ID features in Station Programming)
Default With Station ID (future feature—selects board level identification for the calling
number ID plus the station ID if available.)
NFAS Membership Mode—Use this feature to specify a board’s role in a NFAS group.
Non-Member (specifies independent, stand-alone DXPT1–PRI board)
Member (specifies DXPT1–NFAS board with D-channel signalling provided by another board)
Primary (specifies DXPT1–PRI board that provides D-channel signalling for the NFAS group)
NOTE: When you are using Visual Man-Machine Interface (VMMI) to program, the system automatically applies
the Member setting where appropriate.
