I'm trying to get a clue how much PC horse power I might need to create a dial plan where T1 inbound connections would be cross-connect to outbound T1. In other words, this would be a "Digital Cross Connect" like application using Asterisk. Total there is 10 inbound T1 circuits and 10 outbound circuits. I'm thinking 3 TE410P cards in two PC boxes with a network cable between them. The dial plan would simply select a route based on the DNIS digits received from the phone company. It is possible that all circuit could be in use for about 1 hour a day. No other features of Asterisk would be needed TIA Bart
