M-43 Multiple Console Operation - CCIS
M-43  Multiple Console Operation - CCIS
General Description
This feature provides console operation where ATTENDANT CONSOLEs [A-3] are installed in more than one
node in the CCIS network.
Operating Procedure
No manual operation is required.
Service Conditions
1. Call transfer among ATTENDANT CONSOLEs [A-3] in different nodes is possible, but call
identification information cannot be transferred from one node to another.
2. When ATTENDANT CONSOLEs [A-3] are installed in multiple nodes, Day/Night mode changeover is
controlled independently in each node.
3. The following types of calls on the CCIS network are identified by the lamps on the ATTENDANT
CONSOLE [A-3]:
LDN
FX
WATS
 CCSA
TIE
ATND
4. When ATTENDANT CONSOLEs [A-3] are installed in multiple nodes, an incoming call is only indicated
at the terminating ATTENDANT CONSOLE [A-3]. No indication is given on the ATTENDANT
CONSOLEs [A-3] at the other nodes.
5. The maximum number of consoles per unit is two.
6. The maximum number of consoles allowed per system is 16 for 1 IMG and 60 for 4 IMGs/IMX-U.
7. Each incoming call is displayed on a console whether idle or busy. If all Attendants are involved in
processing calls when another Central Office call arrives, the Call Waiting Lamp will light on all consoles.
This is Switched-Loop Attendant Operation.
8. If one of the consoles enters the Night mode, all calls addressed to the Attendant will be directed to the
other consoles. However, the console which has entered the Night mode must complete processing of all
calls already connected to its loop.
9. A station can be connected to only one Attendant loop at a time. Any attempt at establishing multiple
connections will result in reorder tone being sent to the Attendant.
10. The NEAX2400 IMX operates only on a switched-loop basis. Fixed-loop operation is not available.
Interactions
1. See ATTENDANT CONSOLE [A-3] for information regarding a single ATTENDANT CONSOLE [A-
3] and system features provided to the ATTENDANT CONSOLE [A-3]. The ATTENDANT CONSOLE
[A-3] must be provided first.
2. For each tenant, only one type of ATTENDANT CONSOLE [A-3] system can be assigned, either normal
or Primary ATTENDANT CONSOLE [A-3] system.
3. ASAT must be programmed for INTERPOSITION TRANSFER [I-5].

Multiple Console Operation - CCIS M-43
Interactions (cont’d)
4. ATTENDANT CONSOLEs [A-3] may not dial another console directly. Talk path will occur only during
INTERPOSITION TRANSFER [I-5].
5. When more than one ATTENDANT CONSOLE [A-3] is installed, a Primary ATTENDANT CONSOLE
[A-3] may be assigned (AMAT command). This ATTENDANT CONSOLE [A-3] will control the
implementation of DAY/NIGHT CLASS OF SERVICE [D-15].

M-67 Message Center Interface - CCIS
M-67 Message Center Interface - CCIS
General Description
This service feature provides an INTERFACE to the external CPU for MESSAGE CENTER information when a
specific UCD group or console in a CCIS network is called. This interface allows external control of Message
Waiting Lamp (MWL) indications on equipped PBX stations.
(Series 7400 software enhancement) This service may be provided through FCCS groups (networks where
multiple NEAX2400 IMXs are connected via FCCS link) and NEAX2000 IVS. When this service is provided
through FCCS groups, it is called Centralized Message Center Interface.
(Series 7400 software enhancement) By the Centralized Message Center Interface function, the MCI message is
transmitted to the shared MCI within the self FCCS group when a call terminates from another FCCS group or the
NEAX2000 IVS to any UCD group within the self FCCS group.
Operating Procedure
The Message Center Interface (MCI) can provide one of two modes of operation. These modes are described
as Feature 1 and Feature 2:
Feature 1:
 Incoming call information is sent to the MCI when an attendant answers. 
 Control of MWLs is based on data from the external CPU. 
Feature 2:
 Incoming call information is sent to the MCI when a UCD station answers. 
 Dual call forwarding service is possible. 
 Control of MWLs is based on data from the external CPU. 
Procedures for each of these two features are as follows:
Feature 1:
1. When the attendant answers a call, the PBX transmits a call handling record to the MCI. The external CPU,
based on the received data, will display a profile of the station/trunk being handled by the attendant on the
monitor.
2. MWL control is based on data from the external CPU. Through the external CPU terminal, when
information is registered, the Host/CPU system forwards MWL control data according to the MWL On/
Off control information sent.
3. The PBX, upon receiving this control data from the MCI, will extinguish or illuminate the MWL,
depending on the subscriber displayed on the attendant’s monitor/display. 
4. The called station will be able to receive a message from the attendant by dialing “0”, or from a computer
terminal by entering his/her identification number.
5. The external CPU, upon retrieval of message information, will transmit a data record requesting the PBX
to extinguish the MWL of the corresponding station. 
Feature 2:
1. The purpose of this MCI is to provide an interface to a Voice Mail System, or a Message Center Computer
which is capable of sending MWL control data to the PBX.
2. In order to perform the data transfer to the external CPU, a station/trunk is connected to a designated UCD
group. These stations in the UCD group are connected to the Voice Mail System/Message Center System
to collect call connection status of MWL control information. Refer to the block diagram on the following
page.
3. The PBX, upon receiving this control data from the MCI, will extinguish or illuminate the MWL
depending on the subscriber displayed on the attendant’s monitor/display.

Message Center Interface - CCIS M-67
Operating Procedure (cont’d)
4. The user at the called station will be able to receive a message from the system by dialing the Pilot number
of the UCD station group connected to the Voice Mail System.
5. The external CPU, upon retrieval of message information, will transmit a data record requesting the PBX
to extinguish the MWL of the corresponding station.
