Can anyone confirm whether this can be done or not? I've found some docs, but nothing that says in black and white that this is possible..or not.
We have a particular situation where we'd like to take a legacy 2621 (16/64) and add a NM-2W. We'd then like to run 4 sets of 2 port Drop and Insert cards. Basically, connecting four remote sites to the first port on each card and dropping 8 channels to the PBX connected on port 2 of each card.
Can the 2621 support 4 cards, with 4 channel-groups, and TDM cross connects on each card?
