*** Voice-grade data circuit testing - without disturbing traffic *** True preventive maintenance *** Network management information - without special modems *** Suitable for North American and CCITT environments *** Test data circuits carrying voice grade modem traffic while they are still in service *** A simple connection to the data circuit carrying the modem signal, at a voice frequency access point, is all that is required *** To measure the impairments that have been added between signal generation and the measurement point *** Compatible Modems (Note: may not represent complete list): Compatible Modem Types (4-Wire): Data Rate Examples: *9600 bps : CCITT V.29, AT&T 209, AT&T 2096 V.29 with 1800Hz carrier 4x4 QAM with 1700Hz carrier. * 4800 bps: CCITT V.27, AT&T 208, AT&T 2048. * 2400 bps: CCITT V.26 A&B, AT&T 201 B&C. *** Measuring Impairments on a Modem Signal: measures the effects of the same line impairments that are measured by a conventional, intrusive TIMS *** Data Logging: result data can be stored in the test set's own internal non-volatile memory *** Out-of-Service Testing: transmit and measure on a tone, so it can interwork with tone sources and conventional test sets *** Transmit & Receive Connectors: WECO 310 & Bantam(option 002)?
