One Management Communications Controller (MCC) card
The chassis requires one MCC card, which is a processor card that
administers and provides diagnostic connectivity to the DSL cards. It acts as
a mid-level manager and works in conjunction with a Simple Network
Management Protocol (SNMP) system, such as Paradyne’s DCE Manager
for HP OpenView, via its LAN port. It gathers operational status for each of
the DSL cards and responds to the SNMP requests. It also has a serial port
for a local user interface to the DSLAM.
At least one Digital Subscriber Line (DSL) card
The chassis requires at least one DSL card, which is a circuit card that
contains four Rate Adaptive Digital Subscriber Line (RADSL) modem ports,
an Ethernet interface to the ISP, and a processor/packet forwarder. The
processor/packet forwarder controls the modems and forwards the packet
traffic via the Ethernet and DSL interfaces. When the 8600 DSLAM chassis is
fully populated, it provides a total of 68 RADSL modem ports. When the
8800 DSLAM chassis is fully populated, it provides a total of 72 RADSL
modem ports.
