Crypto Resync

If a cryptographic encoder/decoder is connected between the system and the network, it may require a resynchronization signal from the system. This is a signal indicating that the system has lost video synchronization due to a network problem and requires that the cryptographic encoder/decoder resync with the equipment at the other end of the connection.

To use this feature, select System Info > Admin Setup > Security.

When you select the Crypto Resync option, the Crypto Resync

Pulse screen appears.

On this screen you can enable crypto resync, set the time between pulses (in seconds), and set the pulse width (in milliseconds).

If the system loses H.320 synchronization while in a call, it sends the resynchronization pulses at the specified rate until H.320 regains synchronization.

The resync pulse is output on the RTS signal. If this feature is enabled, the RTS signal no longer functions as the Ready-To-Send signal.

Most installations that use encryption equipment require a custom cable. The cable should route the RTS signal from the system to the appropriate resync input on the encryption equipment. The encryption equipment can get its RTS input from the videoconferencing system's DTR output or by tying this input high. In this non-dialed mode, the DTR output and RTS output act alike.
