Comtech EF Data VMS v3.12.x Vipersat - Manual (Page 163)

Chapter 3 - VMS Configuration 3-63
MN/22156, rev 12 Network Manager Configuration
If the fields do not populate, communications with the Hub are impaired and
will have to be restored before the site can be successfully InBanded for the
forward path.
Note: The value that appears in the Power field corresponds to the Hub TDM
setting. Because this setting is determined based on ensuring a link with
the weakest Remote in the group, the value may be excessive for what
this Remote requires. It is recommended that this value be adjusted per
Remote as necessary to provide sufficient power under clear sky condi-
tions.
25. The choice to select the Home Demodulator device is presented. However,
note that this field is automatically filled with the selection made when the
Return Path Settings were configured.
26. Set the Minimum and Maximum Receive Switch Rate Limits for this
site. These values set the transmission data rate range for governing the
remote to operate within the budgeted switching constraints
Units must be included in the entry—use bps, kbps, or Mbps.
The default values are 64 kbps and 4.95 Mbps, respectively.
27. Click on Apply to establish these new parameter settings in the VMS, then
Close the window.
Repeat the above InBand procedure for all applicable Remotes.
Set InBand Reservations for Guaranteed Bandwidth
The InBand Bandwidth Reservation ensures that the Remote is always guaran-
teed bandwidth up to the rate that is specified. Beyond that, the Remote will
only be granted additional bandwidth when it is available. Should system condi-
tions occur that require some Remotes’ data rates be reduced due to a shortage
of bandwidth resources, those Remotes that own pre-allocated reservations will
never be reduced below their guaranteed rate.
Reservations can be configured independently for the Transmit modulator and
the Receive demodulator of a Remote data unit. Perform the following proce-
dure for setting the InBand Tx Bandwidth (when return path switching is
enabled) and/or the InBand Rx Bandwidth (when point-to-point forward path
switching is enabled).
