choosing a value for this allocation, future bandwidth requirements for the chan-

Hitless Switching
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.

Modulator Delay
This field allows the operator to insert additional delay to buffer more data after
modulator transmission is ceased.
