ABSTRACT:
Facsimile data is routed from a transmitting device to a destination device. Responsive to detection at a first port of a received off-hook condition signal and of a set of destination identifying signals, a front-end router provides sequentially at a second port an off-hook signal, signals representing a stored telephone number of a store-and-forward service device, signals representing stored store-and-forward service access authorization information, signals representing the set of destination identifying signals, and a facsimile mode invoke signal. A communication path is enabled between the two ports. Data is transferred to the store-and-forward service through the router. Thereafter, responsive to detection at the first port of a received on-hook condition signal, an on-hook condition signal is provided at the second port.
