TNZ5UNQ2 is a 4-port 10G universal line service processing board applied to Huawei OSN 1800 II Enhanced, OSN 1800V. The UNQ2 board is a universal line board and supports hybrid transmission of ODU0, ODU1, ODU2, ODU2e, ODUflex, VC-12, VC-3, VC4, and packet services with the total bandwidth not exceeding 40 Gbit/s (the total bandwidth of SDH services does not exceed 20 Gbit/s). It can also receive and transmit only one or two of the three services. The UNQ2 board processes and converts the received service signals into four OTU2/OTU2e signals, which are carried over four ITU-T G.694.1-compliant DWDM wavelengths.

For 1800 V, TNZ5UNQ2 inserted on a slave subrack can function only as a pure OTN board.

TNZ5UNQ2 supports only OTN features when it is used together with the TNZ8XCH board.

For 1800 II Enhanced, a TNZ5UNQ2 board supports at most 5 Gbit/s bandwidth of SDH services, and does not support STM-64–>ODU2–>OTU2.

Q: What is the of TNZ5UNQ2 when it functions for packet service?

A: Processing capability is 40 Gbit/s.

But on OSN 1800 II Enhanced chassis, if OTN services are configured, TNZ5UNQ2 supports a maximum of 30GE packet services.

Q: What is the Max bandwidth of SDH services that TNZ5UNQ2 can support?

A: TNZ5UNQ2 MAX total bandwidth of SDH services does not exceed 20 Gbit/s.

Q: What is the difference between HSNQ2 and UNQ2?

A: HSNQ2 supports OTN and SDH, functions such as OTN ports and SDH overhead processing.

While UNQ2 supports OTN, SDH, and packet services, functions such as Layer 2 switching, OTN ports, and SDH overhead processing.
