适用范围

This modem is intcnded for use on connections on general switched telephone networks (GSTNs) and on point-to-point 2-wire leased telephone-type circuits. The principal characteristics of the modem are as follows: a) duplex mode of operation on GSTN and point-to-point 2-wire leased circuits; b) channel separation by echo cancellation techniques; c) quadrature amplitudc modulation for each channel？with synchronous line transmission at 2400 symbols/s; d) synchronous data signalling rates shall be implemented in the modem e) compatibility？ with？ Rccommcndation V.32？ modems at？ 9600？ and 4800 bit/s; f) exchange of ratc scquences during start-up to establish thc data signalling rate; g) a procedure to changc the data signalling rate without retraining.
