Support OTN, SDH, and packet services, and functions such as Layer 2 switching, OTN ports, and SDH overhead processing. Supports Intra-Board 1+1 Protection, Tributary SNCP, ODUk SNCP (k = 0, 1). Supports ESC communication. Supports Electrical-layer ASON. Supports inloops and outloops on VC-4 paths and virtual ports. Supports outband data communication network (DCN). Supports 1:1 PW FPS, 1:1 PW APS. Supports MC-LAG, LPT, Packet SNCP, MC-PW APS, MRPS, LLDP, HQoS, Inband DCN, IGMP Snooping. 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.
