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.

SYSTEM DESCRIPTION
4. FEATURE DESCRIPTION
As shown in Figure 2-2, a direct call or a forwarded call from a station/trunk/Attendant terminates to the VMS
station in the UCD group or Hunting group.
When terminating a call to the VMS, the AP00 sends a call connection status information to the VMS through
the MCI. If the ANI information is sent from the network, the ANI information can be added to the call connec-
tion status information by the system data programming (this feature is not available when the call is received
from the CCIS trunk to the VMS.).
When the station/trunk/Attendant leaves a message in the VMS, the VMS sends a Message Waiting lamp on
data for the appropriate station through the PBX. After the station retrieves the messages, the VMS sends a Mes-
sage Waiting off data for the appropriate station through the PBX.
When accessing the VMS, the connecting patterns shown in Table 2-2 are possible.
