S/UNI®-ATLAS-3200 Telecom Standard Product Data Sheet
Preliminary
Xlate_From_IBCIF
When this bit is logic 1, then all cells from the Input Backwards Cell Interface are translated
as if they came from the Input Cell Interface, i.e. as controlled by the XVPIVCI, XPREPO,
XHEC, and XUDF, and Cell_Info_to_OCIF bits. This is the default choice. When this bit is
logic 0, no header translation is performed on cells from IBCIF except as specified by
IBCIF_P2_To_HECUDF and IBCIF_P2_To_P1.
Reserved
This function is not supported.
Rtd_LB_to_UP_at_End
When this bit is logic 1, then on connections with LB_Route = “01” or “10”, Returned
Loopback cells are routed to the microprocessor at flow end points whether or not the Source
ID of the Rtd LB cell matches the value programmed in the Loopback ID Registers. When
this bit is logic 0, Returned Loopback cells are routed to the micro only if the source ID in the
cell matches the value programmed in the Loopback ID Registers.
APStoOCIF
When APStoOCIF is logic 1, APS Coordination Protocol cells are not dropped at OAM flow
end-points. When APStoOCIF is logic 0, APS cells are dropped at flow end-points like other
OAM cells. APS cells may be copied to the Microprocessor Cell Interface or BCIF on a per-
VC basis via the APStoUP bit in the VC Configuration field of the VC table, and the
APStoBCIF bit in this register.
APStoBCIF
If the APStoBCIF bit is logic 1, then for those connections which the APStoUP bit is set to
logic 1 in the VC Table Configuration field, the APS cells will be routed to the BCIF instead
of to the microprocessor.
LBtoOCIF
When LBtoOCIF is logic 1, Loopback cells are not dropped at flow end-points or due to
LB_Route functionalitybut will be passed to the OCIF. When LBtoOCIF is logic 0, all
Loopback cells are dropped at flow end-points. Regardless of the setting of this bit, the
routing of Loopback cells to MCIF and BCIF is controlled by the LB_Route[1:0] bits in the
VC Table OAM Configuration field. This bit is intended to be used when an external device
is handling the OAM-LB function.
