Signaling
Use this procedure to specify whether the type of dialing signal from the Iota
telephone company is touch-tone or rotary. Touch-tone dial mode cannot be
programmed for immediate-start DID trunks.
Touch-tone single-line telephone users cannot make calls by using individual
trunks programmed for rotary operation. The touch-tone signals generated from
the telephone while dialing are transmitted to the central office at the same time
the rotary signals are sent to the system. The central office receives both signals
and cannot process the call.
