This drop-down box allows the operator to select the Pool/Account ID
(customer account number) from the list that will be used for billing purposes,
for the currently selected Channel. The only Pool/Account IDs shown on the
list are those that have been previously created by the operator in the Space
Segment window, as part of adding Bandwidth Pools during the system setup.

The AUPC feature takes advantage of the Automatic Uplink Power Control
capability of some traffic modems. This allows Ku-band terminals, for
example, to deal with rain fade without excessive communications with the
controller server to exchange E

readings and updated power levels.
When initiating a call, AUPC is enabled only if both channels are capable of
AUPC, as indicated in the database. If either channel is not AUPC-capable,
the call is run without AUPC, allowing for interoperability with other modems.
For AUPC calls, the controller server determines the power level in the usual
way, and stores it as the nominal power. The maximum power is the nominal
plus the delta specified in the channel record. The controller server limits the
maximum value to the maximum allowable power of the modem in use. The
minimum power is set in a similar fashion.
The AUPC checkbox and associated Settings… button provide the means for
enabling or disabling the AUPC function, and for setting the AUPC parameters
(on a channel basis). This configuration information must then be passed on to
the affected node.
To enable Automatic Uplink Power Control for the selected channel, click the
AUPC checkbox so that it is checked. To disable the feature, click the box to
remove the check mark.

controller will use its default value of two seconds.
