Investigation of Group 3 and Group 4 Store and Forward Facsimile Switching Service.

摘要

This report investigates store and forward switching services for Group 3 and Group 4 facsimile. The CCITT has defined operational requirements for a store-and-forward facsimile switching service in Recommendation F.162. Customers can register lists of destinations to which they transmit identical messages, and can then initiate transmission to these destinations by input of a single address code. The systems need not transmit a message to the required customes simultaneously. Customers can send the message to many locations by entering the destination address sequentially before transmitting the message. The multi-address facility differs from the Broadcast facility in that it is not necessary to specify destination addresses in advance. Broadcast facility would therefore be used for transmitting multi-destination messages on a regular basis; multi-address facility would be used for occasional multi-destination messages. Facsimile, Group 4, Group 3.
