ISDN PRI redundancy on AS5300

satish_kirve · ‎12-27-2005

I am having cisco AS5300 router with a ISDN PRI line terminating over it.

I would like to have redundancy for the existing PRI line with another PRI.

Is this possible ? If yes where can I get a sample configurations.

Hi

I feel u will get a new dialin access no for the new pri line ,if thats the case it may not work without changing/informing the customer to add the new number as their secondary dialout no in the configs..

We have done APS configs for different POS Interfaces connecting STM links in GSRs.But dont think tht will be applicable over here with 5300 ..

If it's redundancy for the dialin, you have two options:

1) Make all the clients add the secondary number to dial

2) Request a single number for the two ISDN PRI's from your telco (this is without a doubt the easiest).

If it's redundancy for dialout, just add the interface in the same dialer pool as the first one...:

interface Serial0:15

dialer pool-member 1

!

interface Serial1:15

dialer pool-member 1

!

Did it help?
