Feature description
This feature allows an End of Selection (EOS) signal to be sent back on a
Direct Inward Dialing (DID) trunk to inform the Public Exchange/Central
Office that the dialing phase of the call has been completed. The signal will
be sent back when one of the following occurs:
• the DID call terminates on an idle station or attendant, an Automatic Call
Distribution (ACD) queue, or a busy station
• the call has been intercepted (the DN is busy, not in service, or
prohibited), and
• the interdigit timer has expired or an incomplete DN has been dialed.
Operating parameters
The Central Office must be equipped to handle the special signaling
requirements associated with the End of Selection feature described above.
