CHAPTER 1 INTRODUCTION
This manual provides the Message Center Interface (MCI) specifications for the NEAX2400 IMX system.
When a call terminates to the attendant or a Uniform Call Distribution (UCD) station, the call information is
sent via the MCI to the Message Center (MC). Based on the call information from the Private Branch Exchange
(PBX), the MC achieves ON/OFF control of the Message Waiting Lamp (MWL) and Message Waiting (MW)
indication of the station. Figure 1-1 and Figure 1-2 show the MCI for a UCD incoming call and an attendant
incoming call.

This section has information on protocol and message responses of MCI for IOC. For detailed information on
each message, refer to CHAPTER 4.
2.1 PBX

2.2 MC 
® PBX
(1) When receiving messages controlling one station, the following text format applies.
(2) When receiving queue is full, the PBX sends Call Type 39. This requests MC to stop transmission. When
the PBX has processed all MWL requests in full queue, the PBX sends Call Type 66. This requests MC
to start sending MWL data.
