I have some netvanta 3200's that I would like to configure to support a bonded T1 (two T1's). I haven't done bonded T1 for more than 10 years (forgot). can you point me to some documentation how to implement a bonded T1 (this will be to ATT as the carrier). They want to sell me a Cisco router (no interest). Please let me know what pitfalls I should look for.
thanks in advance
Pretty much like this: Re: Bonding multiple T1 in Adtran 3305 with additional NIM
The document isn't 100% clear, you'll want a cross-connect from each of the T1 interfaces to the ppp interface (document just lists one).
This assumes that AT&T is using PPP as the protocol. If frame-relay, it's similar but with a freme-relay interface and a few added commands for LMI-type and DLCI.
