Abstract
Timers involved in facsimile transmissions under the T.30 specification are permitted to adapt to a given situation to improve the chances for successful facsimile transmission over high latency communication networks. The specified T1 through T5 timers for facsimile transmission may be modified in value based on call control related parameters or facsimile transport related parameters. The timers may be set to have a particular range, with a nominal base value and a maximum value, which may exceed the T.30 timer specification. The adaptive timers can be modified based on a number of different criteria related to facsimile transmissions to avoid overlapping command-response situations and stalemates that may result from communications in relatively highly latency networks. The timers may also be adapted to minimize or optimize call length while achieving successful facsimile transmissions.
