I am planning to connect two Nortel PBXs through my data network to simulate a toll bypass system (Using analog phones). Currently the two PBX are connected by T1 circuit. I will be using 2800 routers on each end.
Which Cisco card/module should I use? Will this solution requires PVDM2?
You'll need a VWIC2-1MFT-T1/E1 on each end (single port E1 or T1 software-switchable card).
You'll also need enough DSPs for 24 channels of voice on each end - if using G711 this would be 24 channels so a PVDM2-32 (or two 16s) would be OK. I'm guessing you'll be using G729 though, so you'll need a PVDM2-48.
You will require a voice capable IOS as well....
I normally start with a voice bundle and add the DSPs/VWICs I need to simplify the order, e.g.:
CISCO2801-V/K9 2801 Voice Bundle,PVDM2-8,SP Serv,64F/256D
VWIC2-1MFT-T1/E1 1-Port 2nd Gen Multiflex Trunk Voice/WAN Int. Card - T1/E1
PVDM2-8U48 PVDM2 8-channel to 48-channel factory upgrade
