This section describes the features and functions of the MCP-IPx controller card.
The MCP-IPx card is the control processor card for Coral IPx 500 systems. The
MCP-IPx card provides RS-232E programming and maintenance interface, Software
Authorization Unit (SAU) and IMC8 interface. See
Figure 8-1
. The MCP-IPx contains a
multi-pin connector and support circuitry for the addition of CLA and DBX baby
cards. It integrates the main processor, memory management circuitry, local bus
interface, real-time clock, generic feature software memory, and database memory.
The MCP-IPx supervises overall system operation by executing system-wide processes.
These processes include port connection management, feature management, generic
feature software installation, feature authorization, configuration database
management, database backup and restoration, program interface input/output and
diagnostic testing.
Port Management
In order to manage port connections and feature operation, the main processor
communicates through the MSBipx (backplane) card via the HDLC buses.,
Communication is enabled with the local card processors on every peripheral card
both in the main and in the expansion cabinets.
The main processor receives status messages from the card processors regarding port
activity. It determines the appropriate response based on the programming entries
contained in the system database. The main processor then instructs the appropriate
card processor what action to take with each port.
1 General Information
Inserting or removing the MCP-IPx control card when power is applied could damage
the card. Before inserting or removing the MCP-IPx control card, verify that the PS500
unit power toggle switch is turned OFF.
