ISDN Configuration

[mail2rravikumar]

Dear all,

I would appreciate if any one could help me in configuring ISDN. We are trying to configure ISDN for one our clients. They have PRI at both the ends and they also have frame relay link between two routers. The idea is they have many subinterfaces on their main frame relay link. They need to configure dialers, so that each subinterface have one dialer as back up.

Also few subinterfaces has 128 kb as bandwidth so we need to configure dialer to fire two B channels and so on.

We have configured several dialer, but we are able to fire only one dialer at a time and we are able to bundle as many b channels required for the dialer, but when we fire the second dialer it does not bind up and throws errors.

Please let us know if any one has come across this issue.

Awaiting your reply...

Thanks & Regards,

Ravikumar

Dear Pushkar,

I am extermely sorry for the delayed response as I was busy on calls. I checked the link but I am afraid if the link helps.

Let me explain the issue again:

Say for . eg: ihave pri at both A and B end. I have four dialers configured on both the PRI 's.

Can PRI ' A ' fire four dialer's at a time to PRI 'B' ?

Awaiting your reply...
