Problem: I was trying to connect a 3com Courrier to a Cisco 2600 with BRI ISDN module, but the Courrier only connected 1 B channel at 64k. Called 3com tech support and followed instruction to enter *V2=5*P=3*D0=1 initializing string, but the multilink still didn't work. Below is the startup-config. I took the dialer map entry out because the 2600 was trying to dial to the 3com modem, and of course it failed. My question is: Are there any additional commands needed to enter to work in this situation? I know how to connect 2 cisco routers together with dialer load-threshold and multilink but that didn't work for the ISDN modem. I did search on www.cisco.com but no luck. Any advise is appreciated.
