AT&T 1987 AT&T Telephone User Manual


 
A call unanswered at the away terminal will be directed back to the home terminal unless
one of the following busy conditions exists at the home terminal: (1) it is a multiline
terminal with both System Access buttons busy and with no idle call coverage receiver or (2)
it is a single-line voice terminal that is off-hook, has no idle Call Coverage receiver, and has
no idle hunt-to station.
While either of these busy conditions exists at the home terminal,
the call will not return to the home terminal. Instead, it will continue to ring at the away
terminal until answered or timed out.
If either of the above two busy conditions ends at the home terminal while the call is
waiting at the away terminal, the call will be directed back to the home terminal. If the call
is sent back to the home terminal, it can be answered or it can receive the terminal’s
hunting or call coverage treatment.
The call coverage treatment given to calls that are
returning from an away terminal differs in two respects from the treatment provided to
calls initially directed to the home terminal.
First, the home terminal and its coverage
station receive ringing simultaneously,
rather than having the coverage ringing delayed.
Second, coverage terminals will ring for calls returning to the home stations even if the call
coverage ring options of the home terminal are “no ring. ” Both of these call coverage
modifications expedite the answering of calls that are returning to the home station from an
away station.
Once the call is directed back to the home terminal, it is removed from the away terminal.
This is true even if the away terminal was busy but subsequently became idle after the call
was sent back to the home terminal.
(2) Call Placed From The Away Terminal: A call to a PDC from the station where it is
logged in will be directed to the PDC’s home terminal.
Calls Placed to a Floating PDC:
When a valid FPDC is dialed, the call will be directed to the terminal where the FPDC is
logged in and will be provided the coverage treatment administered for that terminal. If the
FPDC is not logged in and if the attendant position is that FPDC’s “home,” then the call
will be directed to the attendant position.
However, if the FPDC call was placed from the
attendant position,
then it will not be redirected to the attendant but will instead be
provided Reorder Tone.
Finally, if the FPDC is not logged in, and if the attendant position
is not that FPDC’s “home,” then the calling party will receive Reorder Tone.
For non-DID calls, if an invalid FPDC is dialed, then the calling party will receive Reorder
Tone. If a DID call does not match any assigned number in the dialing plan, it will be
directed to the attendant or to Reorder Tone, as administered.
Considerations
The Personal Dial Code (PDC) feature provides flexibility for users and visitors. Visitors,
once assigned a FPDC, can inform callers and the attendant. Calls can then be directed to
the voice terminal where the FPDC is logged in.
Calls to FPDCs not logged in may be
directed to the attendant for further handling.
