Hitless Switching Parameters

Unless inherent delays in configuring both ends of a satellite bandwidth link
during dynamic switching are accounted for, transmitted data may be lost
during the transition. The time for a switch command to be sent across the satel-
lite link (~ 250 ms), the command processing time, as well as receiver acquisi-
tion time must be considered. The Vipersat Hitless Switching feature provides
a means to coordinate timing and utilize buffering to eliminate these data
outages.
To access the Hitless Switching screen, enter H from the STDMA/SCPC Auto
Switching screen (see figure 3-41).
