MANUAL VERSION 11.0 – May 2008
T1, T1/PRI, or E1/PRI Card Configuration and Programming
* Currently, the overlap sending/receiving protocols are supported with PRI Net 5 and BRI Net 3 switch
types, which are prevalent in the Europe and Mexico markets.
Call Type
3.87 (T1/PRI Only) All Primary rate ISDN calls have a specific number type (International,
National, Network, or Local/Subscriber) and numbering plan field (ISDN, Telephony, or Pri-
vate) indicated in the call setup message to the public network peer. In certain cases, front end
equipment interfacing with the ISDN user (CPE) peer requires a specific number type and/or
numbering plan. The number type and numbering plan are programmable per call type for each
equipped primary rate card. The operation of this feature is transparent to the user. After the
number type and numbering plan are programmed, the Primary rate call setup message will
include this information for each call. To set the Primary Rate Call Type for a T1/PRI card,
select
System and Cabinets, then double-click on the card (or right-click and select Explore
Card). Then select
Call Type.
Description
3.88 You can enter a description for the card. Select its current Value and enter the descrip-
tion in the text box. Then press
ENTER or click on another field to save the change.
Release (T308) 4 1-255
seconds
If the appropriate Release response (Release Complete) is not
received before this timer expires, the requesting system sends
another Release or releases the B-channel and Call Reference
value.
Restart

120 1-255
seconds
The system initiates this timer when a Channel Restart message
is sent. The timer is terminated when the Restart Acknowledge is
received from the public network. If the Restart Acknowledge is
not received before this timer expires, the system sends a sec-
ond Restart message to the public network. If the timer expires a
second time and a Restart Acknowledge has not been received
from the public network, the system idles the respective channel.
Resume Acknowl-
edge (T318)
9
seconds
1-255

Acknowledge or Resume Reject) is not received before this timer
expires, the requesting system sends a Release Request.

This timer controls the amount of time the ISDN Data Link layer
will wait for an acknowledgment from the network before it trans-
mits a frame again.
