8620 BAC Management, Aggregation, and Line Cards
The 8620 BAC accepts the following types of cards:
„
SCP card
Provides aggregation of DSL traffic on the ATM bus for the chassis, and
administers and provides diagnostic connectivity to the line cards. The SCP
card acts as a mid-level manager and works in conjunction with an SNMP
network management system such as OpenLane
®
via its LAN port or inband
management channel. It gathers operational status for each of the line cards
and responds to the SNMP requests. The card also has a serial port for local
terminal access. The SCP is designed as a replacement for both the MCP
card and the SCM card.
