Follow up to your question regarding connecting two phone systems over a FT1. In Verizon East (Former Bell Atlantic) FT1's are treated as pure digital data (DDS) circuits.
The FT1 DS0's groomed at a DACS are not capable of carrying DS0 robbed bit signaling within each channel pair cross-connect. The robbed bit signaling option is either TRANSPARENT MUX (TRSP, MUX), or just plain old TRANSPARENT (TRSP).
Even if you were to use a D type channel bank at each end, without robbed bit signaling capability in the FT1 you will not be able to signal across the link unless you use in-band signaling or VoIP.
