Sect. Functional Description
(Remote Control) Used to define whether the modem is being controlled
5.2.2.1.1
locally, or remotely.
Used to completely configure the modem. Follow the step-by-step prompts to
5.2.2.1.2 make choices or edit data. This is highly recommended for new users, as it
provides guidance through all the configuration parameters.
(Transmit) Used to define, on a parameter-by-parameter basis, the transmit
5.2.2.1.3 configuration of the modem. Use the available submenus when there is a need
to change, for example, just the Transmit IF Frequency.
(Receive) Used to define, on a parameter-by-parameter basis, the receive
5.2.2.1.4 configuration of the modem. Use the available submenus when there is a need
to change, for example, just the Receive Data Rate.
5.2.2.1.5 (Clock Extension) Used to define the G.703 Clock Extension interface.
Used to define operation in a transparent mode (no framing) or in a framed
mode. In the framed mode, an overhead of 5% or 1.6% is added to the rate
5.2.2.1.6
transmitted over the satellite so that M&C and AUPC information may be
passed to the distant end.
(Interface) Used to define which electrical interface type is active at the data
5.2.2.1.7
connectors (either the EIA-530 port, or the G.703 ports).
(Reference) Used to define whether the modem should use its own internal
5.2.2.1.8 10MHz reference, or phase lock to an externally applied reference and, if so,
at what frequency.
Used to mask certain traffic alarms, which may cause operational problems. For
example, certain multiplexers use 'all ones' as an idle pattern. However, by
5.2.2.1.9
convention, the 'all ones' condition is taken to be the Alarm Indication Signal
(AIS). If desired, this alarm may be masked.
On the CDM-570L only: Used to configure a BUC (Block Up Converter) or LNB
(Low-Noise Block Down Converter), if connected.
