590CHAPTER 37: ISDN CONFIGURATION COMMANDS

undo isdn spid1

View ISDN BRI interface view

Parameter spid: String of 1 to 20 digits.

LDN: Local dialing number, a string of 1 to 30 digits.

Description Use the isdn spid1 command to configure SPID information for the B1 channel on the NI-compliant BRI interface.

Use the undo isdn spid1 command to remove the SPID information of the B1 channel on the interface.

On a BRI interface compliant with the ISDN protocol (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. By default, dynamic negotiation. Only after SPID information is configured for the B1 channel on the BRI interface can the system makes the L3 initialization to place calls normally.

In addition, when the router works with an ISDN NI compliant switch (the DMS100 for example) in North America, you must use this command to configure a unique SPID and LDN for each B channel to ensure a successful MP channel call. Otherwise, only one B channel can be brought up. Also note that both SPID and LDN are provided by your service provider and the configuration of LDN voids the configuration of the isdn calling command.

By default, Both SPID and LDN for the B1 channel on the BRI interface are null.

This command applies only on NI-compliant BRI interfaces.

Example # Set SPID to “012345” for the B1 channel on the interface BRI 1/0.
