LOCAL CONTROL PROCESSOR (LCP)
The Local Control Processor (LCP) card is installed in a dedicated processor slot, slot 10,
of each Expansion KSU and does not reduce the available universal card slots of that
cabinet. The LCP card has positions for three daughter boards. The first daughter board
position (SCP-D1) can support one of two types of daughter board, a Multi-Frequency
Module (MFM), or an R2/CID Module (RCM). The second daughter board position (SCP-
D2) can support the MFM, the RCM or the MISC. The third daughter board position (SCP-
D3) can support one of two types of daughter board, a Multi-Frequency Module (MFM), or
an R2/CID Module (RCM).

2.2.2 PROCESSOR CARD DAUGHTER BOARDS
There are seven types of daughter board that fit on the various processor cards. Some
daughter boards will only work on the Main Control Processor (MCP) and the rest will work
on any processor card. The various daughter boards and their uses are described below.
INTER PROCESSOR COMMUNICATIONS AND
MEMORY MODULE (IPM)
This daughter board installs in position MCP-D2 of the Main Control Processor and is
required to provide the inter processor messaging channels in a multiple cabinet system.
The IPM daughter board also carries the expanded SRAM and DRAM needed for multiple
cabinet systems and single cabinet systems running L version software.
The IPM daughter board consists of the following:
One (1) MC68302 25 MHz Processor (for message handling)
!
One (1) megabyte SRAM (for customer database)
!
Four (4) megabytes DRAM (for the operating system and scratch pad)
!
Three (3) synchronous communications ports (to communicate with the SCP and the
!
LCP's)
