The common control portion of the Coral IPx 500 system provides the control
mechanism for establishing audio and data connections or calls between peripheral
I/O ports in the system via the PCM bus. Common control is divided into the
following functions:
Main processor
Generic feature memory
Database memory
IMC8 control
Peripheral bus interface or group controller
The Coral IPx 500 common control card set consists of an MCP-IPx main processor and
database memory, one IMC8 generic feature memory baby card, an optional DBX
database memory expansion and an optional CLA card.
The MCP-IPx card resides in a designated card slot in the card cage; the CLA and DBX
cards are smaller baby cards that are mounted on the MCP-IPx card. The IMC8 card
resides in a special slot in front of the MCP-IPx card. The card slot designation appears
below each card slot on the front of the card cage. Refer to
Chapter 6 - Cage Description
,
for more information.
The MCP-IPx card is the "core" of the Coral IPx 500 common control. The card contains
the main processor circuitry, memory management circuitry, local bus interface and
database memory (protected against power loss by a long-life lithium standby battery).
It also provides a real-time clock and hosts the system authorization unit (SAU).
Additionally, the MCP-IPx acts as a mother card to one CLA card or up to two DBX
cards. The main processor receives status messages from ports in the system and
determines the appropriate response based on programming entries contained in the
system database.
The IMC8 card provides memory space for the generic feature software of the Coral
IPx 500 system. The generic feature software determines the operation of telephony
functions of the system. The IMC8 uses flash memory technology to provide
high-reliability, non-volatile storage for the generic software and system database,
combined with the capability of field software upgrade.
