S/UNI®-ATLAS-3200 Telecom Standard Product Data Sheet
Preliminary
InactiveToUP
When InactiveToUP is logic 1, all cells received on connections whose Active bit is logic 0 in
the VC Table (as well as cells received on connections that have their DRAM_CRC_Err bit
logic 1 if the Inact_on_DRAM_Err register bit is logic 1, and all cells whose connections
have misconfigured VPC pointers) are copied to the Microprocessor Cell Interface.
Regardless of the state of this bit, all cells received on inactive connections are dropped by
the CP (i.e. not sent to the Output Cell Interface).
DROPCRCEOAM
If the DROPCRCEOAM bit is logic 1, all OAM cells with an errored CRC-10 are dropped
(i.e. not routed to the Output Cell Interface). Regardless of the state of this bit, if the S/UNI-
ATLAS-3200 is a flow end-point, all OAM cells with an errored CRC-10 are dropped.
CRC10toUP
If the CRC10toUP bit is logic 1, all OAM cells or RM cells with an errored CRC-10 are
copied to the Microprocessor Cell Interface. Regardless of the state of this bit, the
DROPCRCEOAM and DROPCRCERM bits determine whether or not the S/UNI-ATLAS-
3200 will route errored OAM and RM cells, respectively, to the Output Cell Interface.
ACTDEtoOCIF
If the ACTDEtoOCIF bit is logic 1, all Activate/Deactivate cells are routed to the Output Cell
Interface. If ACTDEtoOCIF is logic 0, then at flow end points, all Activate/Deactivate cells
are dropped. Regardless of the state of this bit, all Activate/Deactivate cells are routed to the
Output Cell Interface if the S/UNI-ATLAS-3200 is not a flow end point for that connection.
ACTDEtoUP
If the ACTDEtoUP bit is logic 1, all activate/deactivate OAM cells are copied to the
Microprocessor Cell Interface at flow end-points. If the S/UNI-ATLAS-3200 is not a flow
end-point for the connection, the Activate/Deactivate cells are not copied to the
Microprocessor Cell Interface. Regardless of the state of this bit, all activate/deactivate cells
are passed to the Output Cell Interface if the S/UNI-ATLAS-3200 is not an end point for that
connection.
ACTDEtoBCIF
If the ACTDEtoBCIF bit is logic 1, all activate/deactivate OAM cells are copied to the
Backwards Cell Interface at flow end-points. If the S/UNI-ATLAS-3200 is not a flow end-
point for the connection, the Activate/Deactivate cells are not copied to the Backwards Cell
Interface. Regardless of the state of this bit, all activate/deactivate cells are passed to the
Output Cell Interface if the S/UNI-ATLAS-3200 is not an end point for that connection.
