Displays for redirected/coverage and returning/third-party
formats:
is not displayed to the
calls have the following
— Screen 1 contains either information about the called party (usually a station
or DGC group) or a feature descriptor that explains why the call has come to
this station (for example, PARK RTN or NIGHT SERVICE).
— Screen 2 always contains information about the calling party (the person who
initiated the call and usually the person on the line when the display station
user answers the call).
Generally, if the System 25 acts on a call without the display terminal user having
caused the action, the result is not displayed.
For example, if a call is forwarded,
there is no indication of forwarding on the caller’s display; this also applies to calls
that are picked up, sent to coverage, parked, unparked, etc.
— Exceptions: Conference/bridging indication of the number of parties on a call;
exclusion indication when excluded from a call.
Generally, if the System 25 redirects a call away from a display terminal, the display
does not present this information.
For example, when a call is picked up by another
terminal, the called terminal does not display this action.
— Exceptions: If a call to a terminal goes to coverage, that terminal’s display
has a “c” in position 16 of Screen 1; if a call is forwarded to an outside
number, the display flashes “F” and the forwarded-to number.
A call-information display will remain on the screen unless one of the following
actions occur:
— The display terminal user presses another call appearance button.
— The user presses another button that causes a system action and/or has
display support.
— The call disconnects.
— The user leaves Normal Mode.
— The user changes switchhook status (from off-hook to on-hook, or vice
versa).
— A call arrives while Automatic Incoming Call Identification is active.
