(DID) calls
553-3021-209 Standard 1.00
Equipment registered for Direct Inward Dial (DID) calls must provide proper
answer supervision. Failure to meet this requirement is a violation of part 68
of the FCC's rules.
Proper answer supervision is defined as follows:
• DID equipment returns answer supervision to the Central Office when
DID calls are:
— answered by the called station
— answered by the attendant
— routed to a recorded announcement that can be administered by the
CPE user
— routed to a dial prompt.
• DID equipment returns answer supervision on all DID calls forwarded to
the Central Office. Acceptable exceptions are if:
— a call is not answered
— a busy tone is received
— a reorder tone is received.
