Hello, I am looking at replacing a bank of PM-3 units and a DS-3 Mux with an Ascend Max TNT. The following configuration was provided to me by a used equipment vendor, and he couldn't answer the question to wether this unit would provide the following needs that I have: 1. Dial In/Out (ISDN, V.92) on all ports 2. Multi-Link PPP Support accross multiple ports. We occasionally do 256k ISDN connections for customers. 3. OSPF Routing TNT-H, 672 port 48DSP, v.92, VOIP, T3 -- Vice President of N2Net, a New Age Consulting Service, Inc. Company http://www.n2net.net Where everything clicks into place! KP-216-121-ST
