Abstract
Broadband modems using data compression insure the physical connection between modems is solid prior to initiating error recovery procedures since its error detection runs on the compressed data. Escape sequences applicable to Transparent Mode of the Compression function enable both duplex and simplex compression functions and provide a more reliable mechanism for completion of error recovery procedures in the presence of subsequent line disturbances. Transparent Mode is used during the re-synchronization procedure. No special compression code words are required to accomplish the procedure, and there is no reduction in the number of code words available for actual compression encoding. The procedure works regardless of whether compression is being used in both directions, only one direction, or neither direction. A new Transparent Mode Command to request that the remote modem send a RESET Command is defined. The new command is termed RRESET.
