Abstract
A cellular modem is configured in one of two modes of fax operation: a standard fax mode or an extended fax mode. In the standard fax mode, the cellular modem completes calls as in the prior art. In the extended fax mode, fax information is transmitted over a cellular-portion of the cellular fax call using a '2-D' fax compression scheme and a data modulation as specified in AT&T Paradyne's 'Enhanced Throughput Cellular (ETC) Protocol'. In this mode of operation, 'AT-commands' related to establishing the fax connection are transmitted from the cellular modem to a Mobile Switching Center (MSC) that includes a cellular modem pool. This allows fax-capable terminal equipment at the mobile end of the connection to communicate directly with a far-end fax-capable modem in the MSC notwithstanding the presence of an analog modem at the mobile end.
