Help with Cisco 2611 to Nortel ASN ISDN BRI backup coniguration

[jeffrey_ala]

I am replacing a Nortel AN at one of our remote sites with a new Cisco 2611XM. This unit utilizes an ISDN BRI for backup purposes.

Does anyone have experience with a Cisco to Nortel ISDN PPP connection?

I have no idea where to start, so any help would be greatly appreciated.

On the nortel, configure it for RFC 1661 compliance under the PPP interface and you may need to fiddle with the MTU and MRU sizes.

This will be through Site Manager since BCC is to large to run on the AN. You will also need to configure a Backup Pool or Demand Pool depending on how your configuring the ISDN. The nortel website has PDFs that cover this configuration you can download for no cost.

I have a doc on the PPP parameters I can send you if you email me.
