Message Center Interface M-26
M-26 Message Center Interface
General Description
This feature provides an interface to an external CPU for Message Center information when a specific UCD [U-1]
group or ATTENDANT CONSOLE [A-3] is called. This interface allows external control of Call Indicator Lamp
(Note) indications on equipped NEAX2400 IMX stations. This feature also provides a socket interface (LAN
interface) for connection to an external LAN.
Note:Call Indicator Lamp on Dterm Series E is used as the Message Waiting Lamp.
This feature also provides a socket interface (LAN interface) for connection to an external LAN.
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. The functions of each feature are as follows:
Feature 1:
1. Incoming call information is sent to the MCI when an Attendant answers.
2. Control of Call Indicator Lamp based on data from the external CPU.
Feature 2:
1. Incoming call information is sent to the MCI when a UCD station is called.
2. Dual Call Forwarding service is possible.
3. Control of Call Indicator Lamp based on data from the external CPU.
Note:Feature 2 is not available when a hot line call terminates to a UCD station.
Feature 1
1. When the Attendant answers a call, the NEAX2400 IMX 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 CRT.
2. Call Indicator Lamp control is based on data from the external CPU. Through the external CPU terminal,
when information is registered, the Host/CPU system forwards Call Indicator Lamp control data according
to the Call Indicator Lamp On/Off control information sent.
3. The NEAX2400 IMX, upon receiving this control data from the MCI, will extinguish or illuminate the
Call Indicator Lamp, depending on the subscriber displayed on the Attendants monitor/display.
4. The called station will be able to receive a message from the Attendant by dialing “0”, or a computer
terminal by entering an identification number.
5. The external CPU, upon receiving retrieved message information, will transmit a data record requesting
the NEAX2400 IMX to extinguish the Call Indicator Lamp of the corresponding station.
Feature 2
1. This provides an interface to a Voice Mail System, or a Message Center Computer that is capable of
sending Call Indicator Lamp control data to the NEAX2400 IMX.
2. To perform the data transfer to the external CPU, a station/trunk is connected to a designated UCD [U-1]
group. The stations of the UCD [U-1] group are connected to the Voice Mail System/Message Center
System in order to collect call connection status of Call Indicator Lamp control information. The block
diagram of this concept follows on the next page.
3. The NEAX2400 IMX, upon receiving this control data from the MCI, extinguishes or illuminates the Call
Indicator Lamp depending upon the information displayed on the Attendants monitor/display.
4. The called station will be able to receive a message by dialing “0”, or by a computer terminal by entering
his/her identification number.

4. If the Host/CPU malfunctions and stops collecting call records, the NEAX2400 IMX can store up to 16
call records. If the maximum of 16 call records is stored and a 17th is generated, the system will write over
the oldest stored record, thus giving the stack the most recently generated call records.
5. MCI data will not be output when a hotline station is terminated to a station that is forwarded to a Voice
Mail System.
6. It can be determined on a UCD group basis whether to send the incoming call information of the call
terminating to a station in the UCD group to the message center CPU. When OVERFLOW - UCD [O-7]
is activated, the MCI operation of the overflow UCD group is followed.
7. When the calling party number is received via the C.O. line/ISDN line/CCIS line, the number is sent to
the MCI. The calling number is output to the additional MCI text format.
8. When activating this feature via the FCCS network, the station number type (Physical Station Number or
telephone number) to be output for MCI IMX format may be designated in system data.
9. When activating this feature via the FCCS network, a maximum of 2 Messages Centers per node are
available.
SOCKET Interface (LAN interface) Conditions:
1. LAN interface and IOC interface cannot be used concurrently for MCI.
2. The socket interface will be used for transfer data to and from the Message Center connected to the LAN.
3. After the link has been released, it will always be the client which presents a link establishment request.
4. The MCI messages which are transferred via the LAN interface is IMX format messages only.
5. Multiple nodes within an FCCS network can accommodate the Message Center (MC).
6. When activating this feature via the FCCS network, a maximum of 32 nodes can be assigned as the remote
node. Stations accommodated in remote node are controlled by the Message Waiting Lamp (MWL) by the
MC.
