DRAFT RECOMMENDED STANDARD FOR SPACE LINK EXTENSION SERVICE MANAGEMENT
Name Definition/Description Data Type Units
pcmFormatOptions
Set of PCM formats that may be modulated onto the
carrier or subcarrier during the lifetime of the Service
Agreement. It contains any combination of the
following values, with no repeated components:
– ‘NRZ-L’—no return to zero-level;
– ‘NRZ-M’—no return to zero-mark;
– ‘SP-L’—split phase level.
The set shall contain at least one component.

Options
The subcarrier waveforms that will be used during
the lifetime of the Service Agreement. It contains any
combination of the following values, with no
repeated components:
– ‘sine’—sine wave;
– ‘square’—square wave.

The default value is 16.
The minimum value allowed for the delay-time
parameter of the TRANSFER-DATA invocations
carried by the transfer service instance.
The length of the Idle Sequence to be used in Carrier
Modulation Mode (CMM) 4 when PLOP-1 is used.
