CHANGE, USER-OPT MENU

Change, User-Opt Menu
This screen allows access to all the user options, which are described in the following paragraphs.

6.10.1 Change, User-Opt, THRESHOLDS Menu

Thresholds: 1:Final BER [1.0E-5] 2:Demod Eb/No [6.0]dB
Change, User-Opt, Thresholds Menu
This screen allows the operator to set thresholds at which a deferred alarm is raised, to allow action to
be taken before the service degrades too far.
The operator may enter a BER at which the deferred alarm is raised should the
estimated USER BER degrade below this threshold.
The operator may also or alternatively set a deferred alarm threshold for the
Eb/No measured by the demodulator. This is the Eb/No as displayed on the
screen whenever the demodulator status is displayed.
The operator may also instruct the modem to raise the deferred alarm if the
interval between buffer slips is less than a preset threshold. The threshold is set
in hours, and may be for example set to 960 hours (40 days) or 1728 (72 days)
to warn if the criteria for clock accuracies for a specific service are not being
met.
If the AUPC feature is active in either `Maintain Eb/No` or `Monitor Distant`
modes (refer to AUPC in section 8.11 on page 156) the operator has the facility
to raise a deferred alarm if the DISTANT Eb/No falls below the user set
threshold. This can be used in conjunction with the AUPC to indicate when the
AUPC has reached the user set limit for maximum Tx power, but the distant Rx
Eb/No has still fallen below the desired limit.

The operator has control over many parameters, which are the subject of either personal or company
preference. A single menu choice
in the following paragraphs along with each parameter.
