7.5 Synchronous Configuration
This section assumes that you are familiar with the asynchronous
encryption mode of operation.
"Synchronous encryption modules must be installed in the
modems before they are able to operate in synchronous
encrypted mode.
The power up menu will display CRYPT OK if an encryption module
is found. In addition the modem should have a software version 7.10
or higher. The modem configuration for synchronous encryption
mode is the same as for asynchronous encryption mode except that
the modem is set to synchronous mode. (&M command or by display
setting). Most synchronous applications use dumb mode as well.
Detection of escape code is not supported in synchronous mode with
encryption.
7.5.1 Switched line (automatic dial):
Assuming the modems are configured from an asynchronous
DTE at 9600 bps:
