Option 11C Mini

Planning and Installation Guide

Part 68 of the FCC’s rules state that equipment registered for Direct Inward 
Dial (DID) calls must provide correct answer supervision.

The definition of correct answer supervision is 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.
