BRI Facilities
The procedures in this section provide the steps for programming the following options for Basic Rate Interface (BRI) facilities connected to a 800 NI-BRI module:
■
■
Service Profile Identifier (SPID) and Directory Number (DN)
Timers
NOTES:
1.
The 800 NI-BRI module is only available in Release 4.0 and later.
2.
If you are adding BRI facilities to an existing system, clock synchronization
must be set correctly. To inspect or change these values, see “Clock
Synchronization” in “Lines and Trunks.”
Service Profile Identifier (SPID) and
Directory Number (DN)
Use this procedure to program the Service Profile Identifier (SPID) and Directory
Number (DN) for each BRI line in the system. Until these values are programmed for each line, the system will consider the BRI line inactive and the line will not initialize.
NOTE:
The system will not be forced idle when SPIDs are entered. However, if for some reason a SPID changes, the line must be idle (no active call on the line) in order to change the SPID.

Timers
Use this procedure to set timer thresholds.
!
CAUTION:
The factory settings for these thresholds are standard and rarely need to be changed. If you are not sure of the correct timer and threshold settings for your BRI lines and trunks, check with your AT&T representative before you make a change. Incorrect settings can cause your BRI lines and trunks to malfunction.
If the network does not respond before the programmed time, the system takes the appropriate corrective action.
Programming Procedures 4–187

The timers are listed below.
■ T200 Timer.
acknowledgement of a message sent from the communication system to the network.
Minimum time that the link layer waits for an
■ T203 Timer.
Maximum time that the link layer can remain inactive.
■ T303 Timer.
Times the delay in network response when the communication system sends a setup message to initiate an outgoing call.
■ T305 Timer.
Times the delay in network response when the communication system sends a disconnect message to clear a call.
■ T308 Timer.
Times the delay in network response when the communication system sends a release message to clear a call.
NOTE:
If you enter an invalid timer value, you will hear an error beep and the value that was previously stored will be displayed on the screen.
Table 4–4 shows the factory setting for each timer and the valid range for each
threshold.
