I would like to verify that this scenario would work. Client has a T-1 circuit with 6 channels split out from an Adtran T-Mux for data to a V.35 serial interface on a router (not Cisco). Plan is to replace existing router with Cisco (1720 or 26xx) and to add a second T-1for data. Can I bundle the 6 channels of the existing with the 24 channels of the new using Multilink PPP for a 1.9MB pipe ? With a WIC1-DSU for the new T-1 interface ? Within a year the full bandwidth of the existing T-1 will be available for bundling.
