Configuring SBI Bus Tributaries: nbcsIntfCfgTrib
This function configures the tributaries of the SBI bus. Attributes are bus output enable
(applicable for outgoing bus only), CAS processing enable, justification request enable, and
transparent virtual tributaries. This function cannot be used when the SBS device is configured
for TeleCombus mode. Payload symmetry is assumed in the incoming and outgoing direction of a
SBS port. If DS0 CAS processing is specified at initialization (by the field
then user relinquishes the control of all the CAS enable bits in the incoming direction of the SBS
(ICASM) to the CSD and this function can no longer be used to access these CAS enable bit on a
per tributary basis. Note that the outgoing direction is still under user’s control even with CAS
option selected at initialization. The CSD enables or disables the necessary number of CAS-
enabled tributaries internally to carry CAS DS0 traffic. The number of dedicated CAS routes is
specified by the API
enabled/disabled symmetrically in both the incoming and outgoing direction in the SBS.
This function accepts a group handle and configures the group of SBS with the same tributary
