Description

The disconnect delay feature determines the time allowed before the terminal disconnects from the communications line when the Received Line Signal Detect (RLSD) is lost.

All countries except the United Kingdom should use the 2 seconds delay. The 60 ms delay is for use in the United Kingdom.

If the terminal detects a loss of carrier and if the user has selected "no disconnect," then the terminal ignores RLSD (CD) after the beginning of the connection.

If the user tries to disconnect and reconnect the line, then the terminal checks if RLSD is asserted before granting the connection. Once it is connected, the terminal ignores the loss of carrier. In this case, the disconnect should be done on DSR going off.
