Configuring Demand Routing for Primary ISDN Modules
Using Demand Routing for ISDN Connections
N o t e
You can set LDNs using the isdn ldn1, isdn ldn2, isdn spid1, or isdn spid2
commands. The router uses whatever LDN1 or LDN2 value that was most
recently entered using one of these commands.
Configuring an LDN for BRI S/T Modules
The LDN is the PTT or PSTN number that the remote peer calls to reach the
BRI interface and establish the WAN link. You must set the LDN in order for
the interface to answer calls.
Setting the LDN. Enter the LDN with the isdn ldn1 command:
Syntax: isdn ldn1 <LDN>
For example, you might enter:
ProCurve(config-bri 1/2)# isdn ldn1 5555551111
You can also set a secondary LDN using the isdn ldn2 command:
ProCurve(config-bri 1/1)# isdn ldn2 5555552222
If you are configuring an ISDN line that uses SPIDs (typically a North American
ISDN line), you can set the SPID at the same time that you set the LDN.
Activating the Interface
The BRI interface must be manually activated. From the BRI interface
configuration mode context, enter:
Syntax: no shutdown
Caller ID Options
If you configure the ProCurve Secure Router to accept ISDN calls from certain
numbers, the router checks each incoming call's caller ID to ensure it matches
your list of acceptable numbers. You can override an incoming call's caller ID
using the caller-id override option. Enter:
Syntax: caller-id override [always <number> | if-no-cid <number>]
Replace <number> with the phone number that you want to use to override
the incoming caller id number. The always option replaces the caller ID for
all incoming calls with the number you specify. The if-no-cid option uses the
specified number only when an incoming call does not have a caller ID.
