3Com to Cisco connect back to back

3Com to Cisco connect back to back

3Com to Cisco connect back to back


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!

RE: 3Com to Cisco connect back to back

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