Switch Controllers NEW
The Modem
Data Protection Switch is a compact shelf assembly designed to provide
logic and control of IF input and output switch units. The switch
controller will provide type 1:N protect switching for a group of
modems. If one on-line modem fails, it will immediately send an alarm by
a dedicated line to the Switch Controller. At almost same time, the
Switch Controller will send switch commands to relevant switches and
configuration information including all controllable functions of failed
modem to the backup modem before it will be switched online.
