PRBS Generator and Monitor
This section describes the functions used to control/configure the PRBS (pseudo-random bit
sequence) generator and monitor for the working and protection links of the SBS in the chipset.
These functions include configuring the payload, traffic pattern for each STS-1s, controlling the
error insertion for each STS-1s and the resynchronization of data received on a per STS-1 basis.
All the functions are applicable only to SBS in the chipset. An error code will be returned if
attempts are made to invoke these functions on NSE or on groups with members other than SBSs.
Configuring payload for the PRGM: nbcsPrgmCfgPyld
This function configures the payload type of the PRBS generator and monitor. The traffic payload
can be one of the following: 12 STS-1s, 4 STS-3c, combination of STS-1s and STS-3cs or a
single STS-12c stream. A group handle is not allowed in this function.
