2×STM4 Ethernet Switch Card TCM Mode N1 Byte Multiplex Demultiplex Processing

2×STM4 Ethernet Switch Card TCM Mode N1 Byte Multiplex Demultiplex Processing

The functions of the O622-2 card,

• Provide 2×STM-4 optical interfaces.

• Perform O/E & E/O conversion and clock extraction & integration.

• Support laser automatic shutdown function.

• Perform 4:1/1:4 multiplex/demultiplex processing.

• Support continuous concatenation of VC-4-4c.

• Support N1 byte processing and TCM mode.

• Provide monitor function for higher order path overhead (J1, B3, C2 and G1).

• Monitor main alarms of section layer and report the result to XCU card as switching criteria for MS protection.

• Implement pointer interpretation and justification in aggregate drop direction, and report the state of each AU-4 signal to XCU card as switching criteria for path protection.

• Support seamless switching between working and protection XCU cards.

• Support line loop back and equipment loop back.

• Support receiving and transmitting optical power report.

• Support remote on-line upgrading of FPGA and BCT software.

• STM-4 optical interface supports several modes including S-4.1, L-4.1, L-4.2 and L-4.3 by changing optical module.
