Parameter
seconds: Duration of the SPID timer, which is in the range of 1 to 255 seconds,
and defaults to 30 seconds.
Description
Using the isdn spid timer command, you can set the duration of the timer TSPID
for an NI-compliant BRI interface to timer_length. Using the undo isdn spid timer
command, you can restore the default duration of the timer TSPID for the
NI-compliant BRI interface.
On a BRI interface compliant with the ISDN protocol in North America, calls can be
placed only after the SPID negotiation or initialization is finished. SPID information
can be obtained via static configuration or dynamic negotiation. The timer TSPID is
started when the terminal originates a negotiation or initialization request by
sending the INFORMATION message. You can use this command to modify the
duration of TSPID.
This command applies only on NI-compliant BRI interfaces.
Example
Set the duration of TSPID on the interface bri0/0/0 to 50 seconds.
