Call Type
(Applies only to T1/PRI-equipped modules.) All Primary rate ISDN calls have a specific number
type (International, National, Network, or Local/Subscriber) and numbering plan field (ISDN,
Telephony, or Private) 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 module. The operation of this feature is transparent
to the user. Once 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 module:
1. Click System, and then click Communication Server.
2. Double-click the module (or right-click and select Explore Module).
3. Select Call Type.
Release (T308) 4 1–255
sec
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
Acknowledge (T316)
120 1–255
sec
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 second 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 Acknowledge
(T318)
9
seconds
1–255
sec
(E1/PRI Only) If the appropriate Resume response (Resume
Acknowledge or Resume Reject) is not received before this
timer expires, the requesting system sends a Release Request.
Re-Transmission

10 1–65535
tenths
This timer controls the amount of time the ISDN Data Link layer
will wait for an acknowledgment from the network before it
transmits a frame again.

This timer controls how long the ISDN Link Data layer will wait
for an XID response from the network before transmitting the
XID Request again. (XID parameter negotiation is not
supported.)
