发明名称 Recovery of bit-rotated frames during facsimile transmissions in a global system for mobile communications (GSM) network
摘要 A system and method for handling facsimile transmissions in a digital communications network, such as a GSM network. In general, the process includes first synchronizing incoming binary-coded facsimile information and then recording the degree of bit-rotation exhibited by the facsimile information. Segregated portions of the incoming facsimile information are identified as either a synchronization sequence, facsimile status information, or neither type. If a portion of the incoming transmission is identified as facsimile status information, any bit-rotated condition present in the portion is compensated for prior to further processing. In addition, once the incoming information has been synchronized, every time thereafter that a synchronization sequence or facsimile status information is identified in a portion of the incoming information, this event is used as an indication that the facsimile transmission is still in synchronization.
