Abstract
A pair of full duplex modems are connected and each is designed to transmit to the other at the same predetermined band rates. One modem is connected to receive data bits for transmission over the channel at a predetermined first (and fast) rate and to transmit its received data bits at a integral number of first transmission bits per band. The other modem is connected to receive data bits for transmission over the channel at a rate slower than the band rate and is designed to sequentially encode blocks of said slower rate data bits into a larger number of second transmission bits for transmission over said channel at an integral number of second transmission bits per band. Means forming part of said one modem for converting said second transmission bits into the slower rate data bits.
