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 cha
