ISDN Configuration Commands 283
Description
Using the isdn spid auto_trigger command, you can enable SPID auto-negotiation
once on the BRI interface running the NI protocol.
On a BRI interface compliant with the North American ISDN protocol, the router
can place a call only after SPID negotiation or initialization. SPID information can
be obtained via static configuration or dynamic negotiation. You may manually
trigger a new SPID negotiation request by executing this command if the SPID
negotiation in dynamic negotiation fails or just for the purpose of testing.
By default, a BRI interface does not originate a SPID negotiation request unless
triggered by a call.
This command applies only on the BRI interface running the NI protocol.
Example
Manually trigger a new SPID negotiation request on the interface bri0/0/0.

Description
Using the isdn spid nit command, you can set the SPID processing mode to NIT
(Not Initial Terminal) on an NI-compliant BRI interface. Using the undo isdn spid nit
command, you can disable the NIT mode on the BRI interface.
By default, NIT mode does not apply on BRI interfaces. Instead, static SPID or
dynamic SPID negotiation is applied.
On an NI-compliant BRI interface, calls can be placed only after the SPID
negotiation or initialization is finished. When the router is communicating with an
NI-compliant exchange that does not support SPID negotiation, you can use this
command to set the SPID processing mode on the router to NIT and the ISDN will
ignore ISPID negotiation and initialization.
This command applies only on NI-compliant BRI interfaces.
