If you :are multiplexing telephone signals on a single channel, a modem signal :reduces the number of simultaneous conversations you can carry. Apologies :if this point has already been made. A 212 or v.22bis modem signal fits well within a standard telephone voice channel, it does not take up more bandwidth. While there are some multiplexing schemes that are more heavily loaded by a -12 dbm modem signal than by a voice signal with peaks 10 or 20 db higher, I doubt that many local calls would involve such high value mux gear.
