Mitel Integration Card (MIC)
(Release 6.1 and later)
The Mitel Integration Card (MIC) is used with the SX-200 Digital, the SX100/SX-200 Analog,
and the SX-2000 S and SG integrations. Refer to MITEL ADAPTIVE INTEGRATION.
■
Voice Control Unit (VCU)
The Voice Control Unit (VCU), located in slot A13, manages the system/voice and voice disk drives
in slots B3, B4, and Cl through C4. The VCU is responsible for manipulating and controlling all voice
data files. It controls the LICs and pre-processes events from the LICs before passing the events to the
CPU. Systems with more than 48 ports require a VCU card with voice memory of 4 megabytes.
■
Central Processing Unit (CPU)
The Central Processing Unit (CPU), located in slot A14, is the master control unit for the VP 300. The
CPU controls the VCU and the optional integration cards. The CPU contains four serial I/O ports.
The first serial port is shared between the internal modem and the system terminal port, which is
accessed at the rear connector J1 or the front connector SP1. As a modem port, the first serial port can
be connected to any telephone port under system software control. The internal modem is a Bell
103A-compatible (300 bps)/Bell 212A-compatible (1200 bps) modem and RS-232C serial connection.
The second port can can either communicate with the optional DID/E&M Trunk Interface via an
RS-232C cable, or be used for RS-232C Adaptive Integration for message waiting and passing call
information from some PBXs. Refer to the Integration manual — ADAPTIVE INTEGRATION.
The third and fourth ports, accessed through J3 and J4, are reserved for future use.
The CPU provides relay closure contacts for a major and minor alarm on J5.
The CPU also contains:
•
Floppy disk controller that controls the floppy disk that resides in slot B5.
•
System time-of-day clock, which is backed up by battery. The battery can keep the clock running
for up to one week if the power fails.
•
System TDM crosspoint switch for control of the TDM bus.
•
Analog to digital converter (A to D) for monitoring system voltages and temperature.
