Abstract
Half-duplex mode in V.34 facsimile modems can be exploited using symbol rate re-negotiation to enhance performance and throughput. The enhancement is useful for facsimile servers and for facsimile transmission over Internet Protocol (“FAX-over-IP”) network applications. Extending the modem's symbol rate from the current maximum of 3429 symbols per second standard to a higher rate of symbol transmission can quickly enhance throughput. The technique is useful for fast primary channel retrains and for situations in which symbol rates are to be reduced. The technique is also useful for changing the requested symbol rate with data rate negotiation in situations in which data rate selection for the new symbol rate may not be known.
