Definition/Description
References the
f401SpaceLink-
CarrierAgreementId that
is bound to the
F401SpaceLinkCarrier-
Agreement data set in the
Service Agreement that shall
be used to validate the values
of parameters in this Carrier
Profile.
Angle by which the RF carrier is
to be phase-shifted with respect to
the un-modulated RF carrier.
Specifies the PCM format of
the data that is modulated onto
the carrier or subcarrier. The
value is one of the following:
– ‘NRZ-L’: non-return to
zero-level;
– ‘NRZ-M’: non-return to
zero-mark;
– ‘BiPhase-L’: bi-phase
level;
– ‘BiPhase-M’: bi-phase
mark.
NOTE – If a subcarrier data
set does not exist for
this carrier
(indicating that the
data is modulated
directly onto the
carrier) the
pcmFormat
parameter applies to
the data on the
carrier. If a
subcarrier data set
exists (indicating that
the subcarrier carries
the data instead of
the carrier), the
pcmFormat
parameter applies to
the data on the
subcarrier.
