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 LOC2 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:
1 MC68302 25 MHz Processor (for message handling)
1.5 megabyte SRAM (for customer database)
4 megabytes DRAM (for the operating system and scratch pad)
3 synchronous communications ports (to communicate with the SCP and the LCP's)
Local Area Network (LAN)
This daughter board installs in either position LOC2 or LOC3 of the Main Control Processor and
provides a 10BASE-T Ethernet LAN connection. In addition to the LAN connection, the LAN board
provides 0.5 megabytes of SRAM to support the increased I/O functions of this card. The LAN
board also provides the hardware to drive the third and fourth Serial I/O ports in the main cabinet
and support for the V90 internal modem.
The LAN daughter board consists of the following:
10BASE-T LAN Interface
0.5 Megabytes SRAM (for expanded database functions)
2 serial I/O ports (maximum asynchronous speed 38.4 Kbps)
Switch And Conference Module (SCM)
The Switch and Conference Module installs on the MCP or the SCM processor cards. In a single
cabinet system the SCM can be installed in LOC1, however in a multiple cabinet system the SCM must
be installed on the SCP as the MCP must have the ESM and IPM daughter boards. The system,
regardless of size can only support one SCM daughter board. Adding a SCM daughter board to the
system increases the number of conference paths in the system from six to twenty four. In addition,
the SCM also adds twelve channels for DTMF and tone detection.
Twelve (12) channels for DTMF Receiver and tone detection
Eighteen (18) conference paths (for a system total of 24)
