PCT No. PCT/FI94/00375 Sec. 371 Date May 23, 1996 Sec. 102(e) Date May 23, 1996 PCT Filed Aug. 26, 1994 PCT Pub. No. WO95/06372 PCT Pub. Date Mar. 2, 1995A method for controlling a connection, especially a wireless connection, between two modems in the event of disturbance, which includes initiating a so-called retrain procedure in the event of disturbance when either one of the modems receives a signal of unsatisfactory quality. In the retrain procedure, the modems transmit predetermined retrain signals to each other in order to achieve synchronism between them. For reliable and rapid disconnection of a connection, the progress of the retrain procedure is monitored, and every time the procedure is stuck in a state other than a data transmission state for a period of time longer than a predetermined limit, the modem is commanded to initiate a repetition of the start-up procedure by means of which the connection between the modems was originally established. |
