Command Reference Guide
isdn ldn
Use the isdn ldn command to specify the local directory numbers (LDNs) for the basic rate interface
(BRI). This information should be supplied by your service provider. Use the no form of this command to
remove a configured LDN. Variations of this command include:
isdn ldn1 <ldn number>
isdn ldn2 <ldn number>
The BRI module requires all incoming calls to be directed to the LDN associated with the
service profile identifier (SPID ) programmed using the isdn spid1 command. All calls to
the LDN associated with SPID 2 will be rejected (unless part of a bonding call).
Syntax Description
ldn1
ldn2
<ldn number>
Default Values
By default, there are no configured LDNs.
Command History
Release 12.1
Functional Notes
Inbound calls are not accepted on interfaces without programmed LDNs. LDNs can also be entered using
the isdn spid command. The isdn spid and isdn ldn commands overwrite the existing programmed LDN;
therefore, the latest LDN programmed takes precedence.
Usage Examples
The following example defines an LDN of 555-1111:
(config)#interface bri 1/2
(config-bri 1/2)#isdn ldn1 5551111
60000CRG0-35E
Specifies the LDN associated with the SPID entered as spid1.
Specifies the LDN associated with the SPID entered as spid2.
Specifies the LDN assigned to the circuit by the service provider. The LDN
is the number used by remote callers to dial into the integrated services
digital network (ISDN) circuit.
Command was introduced.
