590 CHAPTER 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.

[Sysname-Bri1/0] isdn spid1 012345
# Assign the SPID 012345 and the LDN 54321 to the B1 channel on the BRI 1/0
interface.
