This option group allows the operator to select either Normal or High Priority
status for the circuit. (Normal is the default setting.)
• Normal – this circuit type will have normal status, when compared with all
other circuits.
• High Priority – this circuit type will preempt normal priority circuits if a
shortage of available bandwidth occurs. In this situation, the Normal
priority circuit will be terminated, and the High Priority circuit will be
established at the upper limit of the bandwidth on the transponder.

Set up these parameters for the origination (From/A) side of the Predefined
circuit. These parameters consist of the Node number, Channel number,
Modem type, and the Communications Settings.

Set up these parameters for the destination (To/B) side of the Predefined
circuit. These parameters consist of the Node number, Channel number,
Modem type, and the Communications Settings.
• If the circuit connectivity type is Simplex, the “To/B” section will
have the Modem type and Communications Settings button disabled,
because the communication is one-way.
• If the circuit connectivity type is Duplex, the “From/A” side of the
Predefined circuit will also serve as the “To/B” side in the two-way
communications, and likewise, the “To/B” side will serve as the
“From/A” side in the reverse role.
A directory number associated with a hunt group may be supplied. In this case,
the end point of the call will be one member of the hunt group.

Select the Activation type for the Predefined Circuit, and set up Scheduled
connections, if necessary.
• Permanent – this type of Predefined Connection is typically used as a
dedicated, exclusive connection for guaranteed availability.
• RTS – Request to Send; this type of Predefined Connection can be
established only from a remote site, and is typically used as an emergency
backup for circuit restoration purposes when terrestrial circuits fail.
