Re: ISDN BRI INTERFACE

Hello Jabbar,

this looks like a cisco BCRAN question, here it goes:

the backup delay 10 60 , means that it will take 10 seconds before the secondary link comes up, after the primary goes down, and it will take 60 seconds after the primary goes back up, before the secondary goes down.

dialer idle-timeout 900:

this command indicates how long the call can stay idle before it is disconnected.

from cisco:

"This command is used on lines for which there is no contention. When contention occurs, the dialer fast-idle command is activated. For example, when a busy line is requested to send another packet to a different destination than it is currently connected to, line contention occurs and the dialer fast-idle command is activated.

By default, this command applies to inbound and outbound calls. For example, if a receiving system needs to make outgoing calls, you might configure it with a short idle timeout.

Only packets that match the dialer group reset the idle timer."

So, I guess it would be 900s

HTH,

please rate this post if it does,
