AT&T 1987 AT&T Telephone User Manual


 
HOLD
Description
Allows users to temporarily disconnect from one call and either place or answer another call.
A single-line voice terminal user can place only one call on hold and must remain off-hook to
retain the held call. A multiline voice terminal user can place as many calls on hold as it
has lines and can hang up without losing held calls.
Single-line users can place a call on hold by flashing the switchhook (the user receives
Confirmation Tone).
The user can then dial another party or return to the held call by
flashing the switchhook twice.
The first switchhook flash sets up a conference call, the
second flash drops the third party; if System 25 Dial Tone, Busy Tone, or Reorder Tone (but
not Ringback Tone) was obtained when the third party was dialed, a
single switchhook flash
will drop the tone and return the user to the held party.
Multiline voice terminal users can press HOLD and subsequently replace the handset or call
another party without losing the held call.
The status LED associated with the held call
winks on all terminals with an appearance of the line, except in the case of a conference call.
In this case, the wink indication is given only to the party who invoked hold. To return to
the held call the multiline user either presses the line button associated with the held call
(VI and V2) or simply goes off-hook if the held call is on a button assigned prime line
preference (V2 only).
Considerations
The Hold feature allows voice terminal users to handle several calls simultaneously. For
single-line sets, placing a call on hold is the first step in transferring or conferencing the
call.
Interactions
Attendant Console: The Attendant does not receive hold indications for lines
(trunks) appearing on the Console unless he/she placed the call on hold.
Exclusion: A call can be placed on hold after Exclusion is invoked. The status LED
of the line appearance button and the Exclusion button will wink.
Music-On-Hold: A held party on an outside line will receive Music-On-Hold if
provided.
Personal Lines: A Personal Line cannot be placed on hold if any other stations are
also off-hook on that line.
