Subrate Controller (SRC) Card - Model No. LNX-SRC-1000
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.
The system supports SRC card redundancy. No more than two SRC cards can be installed in a switch.
The card has 4 Mb of battery-backed RAM.
The SRC card resides in the front slot of a CSP 2090 or CSP 2110 chassis.
The part number, serial number, model number, and revision are located on the back of the board.
The SRC card is designed to the following electrical, physical and environmental specifications.
