Defining Signaling Timers
You can change the default values for signaling timers. Table 4-1 provides the
BCC name, Site Manager name, default value, range, and description for each
timer.
Caution:
Nortel Networks strongly recommends that you use default timer
values. These values work properly under most ATM network conditions.
However, if you do change any of the timer values, you must also change the
values at the other end of the UNI (that is, at the local ATM switch).

alert-rx-timer T301 180 180 to

Specifies the Alert Received timer value (in
seconds). This timer begins when the circuit
initiates a call/connection request by receiving an
ALERT message over the signaling VC.
The Alert Received timer stops when the circuit
receives a CONNECT message (indicating
connection) from the network.
If the circuit does not receive a CONNECT
message within the allotted time, it clears the
connection.
This timer can be used with UNI Version 4.0 and
later.
