Intel Confidential | Intel MD566X manual

56K V.92 Data, Fax, and Voice Chipset

allows the DTE-to-modem data rate to be different from the modem-to-modem data rate. Users can take advantage of this feature by setting the DTE-to-modem rate to a high speed like 115,200 bps and letting the modem negotiate the best line rate.

The MD566X chipsets can be configured (by the +MS=m command) to support either asymmetrical or symmetrical connections. The modem transmits and receives at the same speed in symmetrical connections and at different speeds in asymmetrical mode. V.90 and V.92 connections are always asymmetrical. V.34 mode connections can be either symmetrical or asymmetrical. Note that the transmitter speed and receiver speeds typically are different for most V.34 connections over the PSTN.
