3Com to Cisco connect back to back

[Guest_imported]

Hello,

Does anyone know the proper set up for connecting a 3Com NBSI 547 router (note: WITH an external SYNC TFRAP CSU/DSU attached) to a Cisco 3500 router back-to-back? I am using the Frame Relay protocol to try to establish the connection.

I think I have the proper Cisco configuration, from Cisco's website, but I don't know what I am missing on the 3Com side, because 3Com no longer provides tech support for their router product line.

The physical set up is this: a rj-45 type cable goes from the back of the Sync TFRAP CSU/DSU device to the back of the Cisco router.

Thanks for any help!

Check the encapsulation statement in the CISCO router it must be specific for using something other than CISCO to connect with other vendors.

How can I get my cisco to talk to a 3rd-party router over Frame Relay?
