MCC Card
The MCC card provides diagnostic connectivity to the HotWire 8800 DSL cards. It
provides the circuitry for both Ethernet and serial interfaces to the chassis. (The
physical connectors are located on the interface module.) The MCC card
provides mid-level management functions for the SNMP management of the DSL
cards and the HotWire 5446 Remote Termination Units (RTUs).
The following table describes the meaning and states of the LEDs on the MCC
