WAN link and TDM protocol

Answered Question
Jun 11th, 2008

Hi all. I have a question regarding a WAN link. A telco has connected two of our firm's locations over a WAN link. They put a Nokia modem and I connected it to my serial interface. But when the question of encapsulation came up the said there is no encapsulation and that the connection is achieved with a classic TDM protocol over unmanageable network from point A to point B. I'm a bit fuzzy on this and in a bit of a dilemma. Does this mean I only configure IP addresses on both side, configure routing and that's that or do I have to do something more?

Any help on this is greatly appreciated.

I have this problem too.

Then just configure proper addressing and routing and you will be fine.

Hi, they are right, there is no encapsulation in itself on a serial circuit.

The protocol to use, you decide it, usually the default HDLC is fine.

Note if you never dealt with routers before, suggest you hire a consultant for help, because there are many things that can cause problems and frustration.

Thanks for the fast reply. It's just that I don't have much experience with serial links. I'll study it in more detail though and configure all the necessary things for the link to function(IP addresses, routing, etc.).
