SMARTMEDIA CARDS
An OfficeServ500 system must have a SmartMedia card installed on the MCP2 since the
card contains the system operating software. The SmartMedia card can also be used to store
a backup customer database to supplement the database stored on the MCP2 card. In
addition, the SmartMedia card can store backup copies of the operating software for the
SCP2, LCP2 and TEPRI cards.
INPUT–OUTPUT MODULE (IOM) BOARD
The IOM installs in the first cabinet and provides access to serial I/O ports 2 and 3 on the
MCP2 card. The IOM board also has provision to have an internal 56K/V.90 modem installed
on it (see ‘Modem Daughterboard’, below).
MODEM DAUGHTERBOARD
The Modem daughterboard installs on the IOM card. The modem provides a 56K/V90
connection to the system for remote administration and/or programming. The card has a
default extension number of 3999 and eliminates the need for an external modem, serial
cable, single line telephone port and serial I/O port on the system.
Interface Cards
These cards provide the interface connections for telephone lines and stations to the KSU
and expansion cabinets. These cards fit into the universal card slots to configure the system
as required. Interface cards are encased in a static dissipative ABS plastic shell to protect
the card during handling.
TRUNK CARDS
Trunk B

it also contains the circuitry needed for Metering Pulse Detection (MPD) or Polarity Reversal
Signal (PRS). It can be inserted in any universal card slot in all cabinets.
8TRK
This card contains eight loop start C.O. line interface circuits with C.O. disconnect detection.
It can be inserted in any universal card slot in any cabinet.
