Not enough info. Are you going to tie the terminal server to the M1 via T1 or what? T1s or ITG are the only way to do a DCH. Also you have to use probably a router with T1 interface type equipment to do this. Just not enough info.
I use the VNS feature for 7 small sites. For this, all you need is an MSDL port for the d-ch in the Opt61/81 size switches & a SDI/DCH card in Opt11/mini size switches, plus a low speed data modem. You could also put this through a LAN
actually, i haven't done a d-ch over a lan for about 7 years as the cost of the router cards is expensive & all mine are local area so the telco charges are small. the issue is that d-ch's are synchronous data, so you need a synchronous data serial interface card for your router at each end
