Abstract

A modem operable to communicate information from a communications link to a host using a universal serial bus includes a modem memory operable to store a plurality of ATM cells. The modem also includes a receive manager operable to receive a plurality of ATM cells from the communications link and to store the ATM cell in the modem memory. The receive manager further operates to format the ATM cells into universal serial bus packets, and to transmit each universal serial bus packet to the host as soon as the packet is full. The modem further includes a short packet instigator operable to determine whether each ATM cell contains a termination condition associated with the content of the ATM cell, and in response to determining that an ATM cell contains a termination condition, to instigate transmission of a short packet comprising a universal serial bus packet carrying less than its capacity.
