Unmapping virtual tributary: nbcsFmgtUnMapTrib
This function unmaps one or more virtual tributaries (largest payload type is STS-1 SPE or TU-3)
from the source SBS to the destination SBS. It is designed to work in both the TeleCombus and
the SBI bus (column and byte) modes. The total number of tributaries to be unmapped is
indicated by
slot alone. In this case, user can set
disconnected regardless of what the source slot is. Doing so will also set up the egress bus
integrity of the tributaries (for rev B SBS devices only).
Setting chipset to loopback state: nbcsFmgtSetLpbkMode
This function sets the switching fabric to the loopback mode. Records of all existing connections
are wiped out. In the centralized model, all SBS and NSE hardware setting are to be changed to
support the system loopback mode. In the distributed model, device(s) present in the local
microprocessor space are updated. It can be viewed as a reset to the entire switching fabric that
puts the system into the known initial state. User should invoke this when a “clean slate” for
connection is desirable. The function updates the offline connection page of all local devices and
user will have to then perform asynchronous page switch upon a successful invocation.
