 Can you combine two 64 ISDN BRI channels into one 128 line?

We have two ISDN lines of 2b+d (BRI) channels. The objective is to get a single B Channel (64) from one ISDN line and another B of 64 from another line and combine it to 128. We are using Cisco's 2621XM router. Can we do that? Is it possible to combine two B channels from different lines to one 128 line?

Software/Hardware used:
Cisco 2621XM router

It should be doable using Multichassis Multilink PPP (MMP) offered by Cisco IOS. You might have to check the compatibility of features of the IOS and hardware on Cisco sites. Also, you might have to check capability of the Windows NT supplied by the service provider. Hope this helps. -Sudhanshu

I presume from your question that you only use one router, so there is no need for multi chassis, as it is only one chassis! It will use whatever channel is connected from itself to the remote router, as you create virtual Dialer interfaces, and associate these with the physical hardware interfaces. Then it can dial any combination and the bandwidth becomes available to the connection.
