Comtech EF Data VMS v3.12.x Vipersat - Manual (Page 106)

Hardware Configuration MN/22156, rev 12
3-6 VMS User Guide
Once the modem/routers have the minumum required configuration and an
installer successfully points the antenna at the satellite and establishes a receive
link, the operator at the Hub site can push frequencies, bit rates, and FEC code
rates to the units at remote sites using the VMS. The frequencies can be
anywhere in the customer’s frequency pool, allowing a thin-route SCPC
connection to be established with the satellite network’s modems.
For example, once communication is established, the Hub operator can set up
the unit for STDMA using the instructions found in each modem manual. After
a reset, the unit will come back online operating in STDMA mode with the
desired configuration.
Once communication is established between VMS and all network devices, the
network is ready to be configured.
