tone. The tone is repeated at a programmable interval. Keysets receive an off-hook
ring signal through the speaker and single line stations receive a tone in the hand-
set. The volume of the camp-on tone can be set by the station user. Camped-on
calls follow Forward No Answer if a Forward No Answer destination has been set.
Optionally any station can be programmed to automatically camp-on to a busy
station instead of having to press the camp-on button or dial a camp-on code.
CENTREX/PBX USE
CENTREX and PBX lines can be installed in lieu of central office trunks. CENTREX
and PBX feature access codes including the command for hook-flash (FLASH) can
be stored under one touch buttons. Toll restriction programming can ignore PBX or
CENTREX access codes so that toll calls can be controlled when using these ser-
vices.
CHAIN DIALING
Keyset users may manually dial additional digits following a speed dial call or chain
together as many speed dial numbers as are required.
CLASS OF SERVICE
The system allows a maximum of 30 station classes of service. Each class of
service can be customized in memory to allow or deny access to features and to
define a station's dialing class. Each station can be assigned different classes of
service for day and night operation.
COMMON BELL CONTROL
The DCCP card provides two relays to control a customer-provided common bell or
common audible device. These contacts must be programmed as members of a
station group and may provide steady or interrupted closure.
CONFERENCE
The system allows six simultaneous conferences up to 5 parties each.
ADD-ON (5 PARTY)
Any combination of up to five parties (stations or outside lines) can be joined to-
gether in an add-on conference. Parties may be eliminated or added after a confer-
ence has been established. *Requires D4SWD to provide gain control when 3 or
more trunks are in the conference.
UNSUPERVISED
A station user may set up a conference with two or more outside lines and then exit
the conference leaving the outside lines connected in an unsupervised (trunk to
trunk) conference.
SPLIT
A keyset user can "split" a conference into separate outside calls, then speak with
each caller privately. Then the individual calls can be conferenced again in any
combination.
