Enter B at the command prompt and specify the correct BUC Local Oscillator
frequency (MHz) that this Remote will be transmitting.

Satellite Frequency Conversion

This menu item appears for the ECMv2 Hub type only.
This parameter, together with the LNB LO Frequency setting, is critical for
determining RF frequency translations between Hub and Remote offsets or data
spectral inversions. Take care in setting these correctly.
Enter F at the command prompt and specify the correct Satellite Frequency
Conversion value (MHz) that this Hub unit.

STDMA Statistics

Entering V at the command prompt in the STDMA screen displays the STDMA
Statistics as shown in either figure 3-37 (Hub) or figure 3-38 (Remote). These
screens provide information for the number of Bursts (Remote only), number of
Burst Maps, and the current STDMA Cycle Length.
Because the Remote modem bursts back to the Hub once every cycle, the
number of Bursts displayed should be a multiple of the number of Burst Maps
displayed, with this multiple determined by the number of cycles per burst map
(1, 2, or more) that has been defined at the Hub. For the example shown in
figure 3-38 (Dynamic Cycle), the number of cycles per burst map is one, and
therefore the number of Bursts equals the number of Burst Maps.
