Hardware Descriptions

SMARTMEDIA CARDS

An iDCS 500 system must have a SmartMedia card installed in the main control processor (MCP) as
the SmartMedia 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 MCP card. In
addition the SmartMedia card can store backup copies of the operating software for the SCP, LCP,
TEPRI, and LAN cards.
INPUT–OUTPUT MODULE (IOM) BOARD
The Input Output Module board installs in the first cabinet and provides access to the two serial I/O
ports on the Main Control Processor (MCP) card. The IOM board also has provision to have an
internal 56K/V.90 installed on it (see 'Modem Daughter Board' section). When the MCP card is
equipped with a LAN daughter board, the IOM board provides access to the LAN interface in
addition to the two serial I/O ports carried on the LAN daughter board.

MODEM DAUGHTER BOARD

The Modem daughter board installs on the Input Output Module card. The modem provides a
56K/V90 connection to the system for use 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.
