log out of a station group. Stations out of a group will not receive calls to that group
but will continue to receive calls to their individual extension numbers. When de-
sired, the user may put him/herself back into the group by pressing the button
again. Users who do not have this button may dial the access code and the group
desired. A station user is allowed to be in several groups, providing a key and the
extender of that group are assigned for each group on the user's phone.
INCOMING CALL DISTRIBUTION
Incoming calls can be assigned to ring a distributed station hunt group. This al-
lows all members of the group to share the call load.
INCOMING/OUTGOING SERVICE
Outside lines are available for incoming or outgoing service. Programming allows
any outside line to be used for incoming calls only, outgoing calls only or both way
service.
INDIVIDUAL LINE CONTROL
Each station in the system can be individually programmed to allow or deny dial-
ing out as well as allow or deny answering for each outside line.
ISDN SERVICE
PRIMARY RATE INTERFACE (PRI)
The iDCS 500 supports Primary Rate Interface ISDN. PRI allows simultaneous data
calls, calling party and calling line identification, high speed call setup and dis-
connect are among the benefits of ISDN calling. The 23+D configuration of ISDN
allows call information to be delivered via the data channel (the "D" of 23B+D)
thus leaving the bearer channels (the "B" of 23B+D) available for single use or
combined use to provide a wider bandwidth for data and video. The iDCS 500
supports the most popular protocol standards in the U.S.
PRI Protocols supported: National ISDN-2 (NI2)
BASIC RATE INTERFACE (BRI)
The iDCS 500 BRI card supports trunk or station level Basic Rate Interface services
(BRI). Trunk or station BRI use is software programmable. BRI allows simultaneous
data calls, called party and calling number identification, high speed call setup
and disconnect are among the benefits of ISDN calling. The 2B+D configuration of
ISDN allows call information to be delivered via the data channel (the "D" of 2B+D)
thus leaving the bearer channels (the "B" of 2B+D) available for single use or
combined use to provide a wider bandwidth for data and video.
