Compression Module - Expansion module - refurbished
The SA-Comp/1 data compression service adapters (CSA) provide high-performance, hardware-based data compression capabilities via simultaneous Stacker compression data compression algorithms with independent full-duplex compression and decompression capabilities on point-to-point (PPP) encapsulated packets. The SA-Comp/1 supports up to 64 compression contexts. There is one compression context per PPP link. The CSA supports the compression and decompression of data passing through synchronous serial interfaces that are configured for a peak line rate of 16 Mbps or lower. You can use the CSA to compress and decompress data passing through any synchronous serial interface; however, the serial interface must be configured to send and receive data at a rate no greater than 16 Mbps. For example, the CSA supports high-speed serial interfaces (such as HSSI interfaces) if the interfaces are configured for a peak line rate of 16 Mbps or lower. On the Cisco 7200 series routers you can optionally specify which CSA the interface uses to perform hardware compression.
