SYSTEM DESCRIPTION
CHAPTER 2 SYSTEM DESCRIPTION
1. GENERAL
This chapter explains the system outline and the system configuration of the MCI.
2. SYSTEM OUTLINE
The Message Center Interface (MCI) provides an interface with a customer supplied Voice Mail System (VMS)
that can send Message Waiting lamp control data to the PBX. The MCI can provide the following operations:
• Incoming call information is sent to the VMS when terminating a call to the VMS.
• Control of Message Waiting lamps is based on information sent from the VMS.
3. SYSTEM CONFIGURATION
The MCI interface is a half-duplex, EIA-RS232C, asynchronous data link that operates under a specific message
protocol and format. The characteristics of the link, the protocol used, and the message text are described in de-
tail in Chapter 5.
The block diagram of the MCI is shown in Figure 2-1. The MCI requires the Application Processor (AP00) to
make a data link with a customer supplied VMS and the analog line circuit (LC) to interface with the VMS.
(1) AP00 (PN-AP00-A card):
The AP00 stores call information for guest or administration station. The AP00 also provides the MCI ports
for a VMS.
The AP00 continually supervises the status of the VMS. If the VMS is not ready for information receiving
(Busy Status), the AP00 temporarily stores the call information into its internal memory. The AP00 is ca-
pable of storing call information of a maximum of 16 calls.
(2) LC (PN-4LC card):
The LC is used for the VMS stations. The UCD or Station Hunting feature is usually provided with the
VMS stations.
