Combining a Point-to-Point T1 and a Frame Relay T1 into One Link

[routercpu]

I have a 2620 router with a point-to-point T1 connected on one interface and a Frame Relay T1 on another interface. Both these WAN circuits connect to a 3640 router. Is it possible to combine these two circuits into one link even if the circuits are not the same (one is a point-to-point T1 and one is a Frame Relay T1) and, if yes, how? Would I use the multilink ppp command?

Thanks

Technically its some what possible, but multilink works best by combining links of the same media and speed. If you go outside these boundaries you will have serious performance issues.

I would not recommend going down this road unless you have room for plenty of head aches.
