Subrate Controller (SRC) Card - LNX-SRC-1000

Description

The Subrate Controller (SRC) card supports one-way and two-way connections and disconnections between any two subrate channels (non-blocking) across all 2048 timeslots in a CSP. The host is responsible for managing subrate channel connections and disconnections. This card is hot swappable. It does not require an associated I/O card.

Redundancy

The system supports SRC card redundancy. No more than two SRC cards can be installed in a switch.

Battery

The card has 4 Mb of battery-backed RAM.

Placement

The SRC card resides in the front slot of a CSP 2090 or CSP 2110 chassis.

Configuration Information

The part number, serial number, model number, and revision are located on the back of the board.
