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
indications on equipped NEAX2400 IPX stations. This feature also provides a socket interface (LAN interface) for
connection to an external LAN. This feature also provides a socket interface (LAN interface) for connection to an
external LAN.
Note:Call Indicator Lamp on DtermSeries E is used as the Message Waiting Lamp.
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 IPX 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 IPX, 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 IPX 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 IPX.
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 IPX, 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.

M-26 Message Center Interface
Operating Procedure (cont’d)
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.
5. The external CPU, upon receiving retrieved message information, will transmit a data record requesting
the NEAX2400 IPX to extinguish the Call Indicator Lamp of the corresponding station.

Service Conditions (cont’d)
4. If the Host/CPU malfunctions and stops collecting call records, the NEAX2400 IPX can store up to 16/32
call records. If the maximum of 16/32 call records is stored and a 17th/33rd 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. The maximum of 2 Message Centers (MC) per standalone system is available. When 2 MCs are connected
to IOC, a MC information is transmitted to both of them. On condition that one of them is in the event of
failure, another can transmit/receive the MC information.
9. Station number type (physical station number or telephone number) to be output for MCI ICS format may
be designated by the system data.
10. Multiple nodes within the FCCS network can accommodate the MC.
11. A maximum of two MCs per node are available.
12. The MC node can control the MWLs of all station in a maximum of 32 nodes.
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. When 2 MCs are connected to LAN Interface, a MC information is transmitted to a MC connected to lower
number port. On condition that a failure occurs at the MC, another can transmit/receive the MC
information. The MC information is transmitted to both MCs. When transmitting the MC information to
lower number port only, assign ASYDL System Data 1 Index 833 bit 2=1 (Single Output).
