5.6.1CONFIG

The sub-branches available are:

CONFIG: Remote Tx Rx Group

Frame Interface Ref Mask ODU

Remote	(Remote Control) This menu sub-branch permits the user to define whether
	the unit is being controlled locally, or remotely.
	NOTE: The unit may be monitored over the remote control bus at any time.
	When in Local mode, however, configuration parameters may only be
	changed through the front panel. Conversely, when in Remote mode, the unit
	may be monitored from the front panel, but configuration parameters may
	only be changed via the remote control bus.
	(Transmit) This menu sub-branch permits the user to define, on a parameter-
Tx
	by-parameter basis, the transmit configuration of the unit.
	(Receive) This menu sub-branch permits the user to define, on a parameter-
Rx
	by-parameter basis, the receive configuration of the unit.
	This menu sub-branch permits the user to group a vertically aligned
Group
	modulator and demodulator into a modem, or to group any compatible plug-
	ins for redundancy.
	This menu sub-branch permits the user to define if the unit should operate in
Frame
	a transparent mode (no framing) or in a framed mode. In the framed mode
	(EDMAC), an overhead of 5% is added to the rate transmitted over the
	satellite so that M&C information may be passed to the distant end.
	(Interface) This menu sub-branch permits the user to define which electrical
Interface
	interface type is active at the data connectors.
	(Reference) This menu sub-branch permits the user to define whether the
Ref
	unit should use its own internal 10MHz reference, or phase lock to an
	externally applied reference, and if so, at what frequency. If the internal
	reference is selected, it can optionally drive the connector.
	This menu sub-branch permits the user to mask certain traffic alarms, which
Mask
	may cause problems to the user. As an example, certain multiplexers use ‘all
	ones’ as an idle pattern. However, by convention, the ‘all ones’ condition is
	taken to be the Alarm Indication Signal (AIS). The CDM-Qx monitors for the
	AIS condition, and if desired, this alarm may be masked.

ODU (L-Band unit only)

(Outdoor Unit) This menu sub-branch permits the user to configure externally connected Low-noise Block Down Converter (LNB) and/or Block Up Converter (BUC) for L-Band units.
