My Application is quite simple, I need dialup support for an initial 60 ports modem and ISDN, service will be delivered over E1 PRI's and ideally I would like to have my backhaul to my main POP to be run by the total control box it would need to connect to a CISCO on a 128k or 256k leased circuit. What do I need to achieve this in terms of TC hardware and what concerns do I need to have re: release versions ? I'm thinking of buying second hand, is this likely to provide issues ? What are the issues with v.92 on the TC boxes ? Would it be simpler to just run a Cisco to Cisco connection for backhaul ? Thanks Damian [Virus scanned by SunBeach - http://www.sunbeach.net]
