Fixed Line Modem DMX501
The fixed line modem module can be configured for a point-to-point
line or for a multidrop modem network. If a modem is configured for
multidrop use, the outgoing carrier is valid only during transmission. If
the QML logger is the master in the multidrop network, the fixed line
modem can be normally configured for point-to-point use.
