and 48,000 bps

56K V.92 asymmetrical connections (receive): 28,000, 29,333, 30,666, 32,000, 33,333, 34,666,

 

 

36,000, 37,333, 38,666, 40,000, 41,333, 42,666, 44,000, 45,333, 46,666, 48,000, 49,333,

If the +MS=m parameters contain conflicting information like “+MS=V34,1,14400,0” with a DTE data rate of 2400 bps, then the modem’s connection attempts always fail, and the modem reports a “NO CARRIER” message. This happens because when the modem receives the +MS=m command, the modem does not check for conflicts of valid parameter information.

Table 17 shows the resulting connection data rate when using non-default values. Because of impairments on the telephone line, the actual connection speeds may be lower than the speeds defined in this table.

For V.92, V.90, and V.34 modulation, the modem can receive data at a different data rate than the transmit data rate. All other modulation types besides V.23 and V.34 use the same data rate for the transmitter and receiver. Use ATW3 to see the modem’s actual receive and transmit data rates (the modem must be configured for ATV1 text response codes). Table 17 shows examples of the resulting connection rate when non-default values are used.
