Title: Half-duplex communication system for preventing collisions
Inventor: JOHN JOHNNY K
IPC: H04N1/32
Filed: 2006-06-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a FAX communication system which prevents a message collision within a half-duplex communication system.  <P>SOLUTION: In a half-duplex communication system in which additional delays in the communication channel may cause a message collision between a message and a response, a timer based collision prevention circuit 40 is utilized to prevent the message collision. The collision prevention circuit 40 determines if the message transmitted by a communication device will be repeated. If the message is to be repeated, the collision prevention circuit 40 sets a countdown collision timer 44 to a predetermined period of time shorter than the shortest repetition interval of the repeated message. A response is only sent to the communication device if the collision timer 44 has not expired. If the timer 44 expires, the collision prevention circuit 40 waits for the message to be retransmitted by the source device before sending the response to the communication device.  <P>COPYRIGHT: (C)2007,JPO&INPIT
