What is a Hotwire Shelf Concentration Module?

A Hotwire® Shelf Concentration Module (SCM) is a circuit card assembly (CCA) that contains a parentcard with an ATM switch, a backplane interface, a processor, a cell mux/demux, and an uplink childcard. The childcard determines the type of ATM uplink supported by the SCM.

When the SCM card is used in a Hotwire 8820 GranDSLAM chassis, it aggregates DSL traffic from each of the DSL port cards in the chassis on the chassis’ backplane bus and concentrates it onto an ATM interface. The model number of the SCM card differs, depending on what type of ATM uplink childcard is being used.
