Configuring the fast-idle Option

You can assign BRI interfaces to more than one resource pool. For example,
you might want to assign backup interfaces to more than one resource pool
because it would be unlikely that two primary interfaces would go down at
the same time. If at all possible, however, ProCurve Networking recommends
that you design resource pools and the connect sequences to avoid contention
for BRI interfaces—especially for primary BRI interfaces.
If all the BRI interfaces in a resource pool are in use and the ProCurve Secure
Router needs to establish another connection, the fast-idle option determines
the number of seconds that the existing ISDN connections will remain up in
the absence of interesting traffic. Because BRI interfaces are in contention,
the fast-idle option drastically reduces the time the demand remains up when
it is not in use.
To configure this setting, enter the following command from the demand
interface configuration mode context:
Syntax: fast-idle <seconds>
Replace <seconds> with a number between 1 and 2147483. (The range is 1
second to more than 596 hours.)
The default setting is 20 seconds.
To return the option to the default setting, enter:
ProCurve(config-demand 1)# no fast-idle

Defining the caller-number Option

When an ISDN call is established, the calling party supplies a Calling Line ID
(CLID). If you configure a caller-number, the demand interface will check
the CLID when it receives calls. If the CLID matches one of the numbers that
you have specified, the demand interface will answer the call. If the number
does not match a number, the interface will not answer the call.
You can enter multiple caller-number commands, allowing the BRI interface
to accept calls from different remote offices or devices.
From the demand interface configuration mode context, enter:
Syntax: caller-number <CLID>
