Huawei TN54TOA Board Product Overview Huawei TN54TOA Board is a tributary board with a maximum access capability of 20 Gbit/s. The TOA board supports OTN interface, ESC and other functions and features. The TOA board consists of a customer-side optical module, a signal processing module, a control and communication module, a 1588v2 module, and a power module. OptiX OSN 6800 supports 3 Level dynamic traffic diversion (optical cross-connection, ODU cross-connection, and the integrated LAN switch). The product features manageability like SDH/SONET and the large capacity and long distance transmission of WDM systems. With advanced technologies, such as Flexgrid ROADMs, wavelength tunable optical modules, 10G/40G/100G, the Layer 2 Switch, the OptiX OSN 6800 has a flexible architecture and suitable for broadband transport. Brand Huawei Model TN54TOA Basic function TOA converts signals as follows: 8 x (125 Mbit/s to 1.25 Gbit/s signals) <,->, 8 x ODU0. 8 x (1.49 Gbit/s to 2.67 Gbit/s signals) <,->, 8 x ODU1. 8 x (125 Mbit/s to 2.5 Gbit/s signals) <,->, 1 to 8 x ODU1. 8 x OTU1 <,->, 16 x ODU0. 5 x 3G-SDI <,->, 5 x ODUflex. 4 x FC400/FICON4G <,->, 4 x ODUflex. Cross-connect capabilities Cross-connects a maximum of 16 channels of ODU0 signals or 8 channels of ODU1 signals through the backplane bus and cross-connect board. Cross-connects a maximum of five channels of ODUflex signals by using buses on the backplane and the cross-connect board. Only the 3G-SDI/FC400/FICON4G services support the ODUflex signals. ESC function Supported PRBS test function Supports the PRBS function on the client side. The PRBS function on the client side is supported only when the client-side service type is STM-1/OC–3, STM-4/OC-12, STM-16/OC-48, or OTU1. LPT function This function is supported only when the TOA board receives FE or GE services on its client side. FEC encoding Supports forward error correction (FEC) that complies with ITU-T G.709. ALS function Supports the ALS function on the client side. Test frame Supported The board supports the Test frame function only when the Service Type is GE(GFP-T). Ethernet service mapping mode Supports encapsulation of GE services in GE(TTT-GMP) (displayed as GE(TTT-AGMP) on the NMS) and GE(GFP-T) modes. Ethernet port working mode Auto-Negotiation 1000M Full-Duplex Huawei TN54TOA Board Product Feature Support PM non-intrusive monitoring function of ODU0 layer. Support PM and TCM functions of ODU1 layer. Support ODU1 layer PM, TCM non-intrusive monitoring function. Support PM function of ODUflex layer Support PM non-intrusive monitoring function of ODUflex layer. Support SM, TCM and PM functions of OTU1 layer. Support up to 16 ODU0 or 8 ODU1 signals to implement cross-dispatching of services through the backplane bus and cross-board. Support up to 5 ODUflex signals to implement cross-dispatching of services through the backplane bus and cross-board. Provide BIP8 byte monitoring (burst mode) to locate line faults. Provide B1 byte monitoring to locate line faults. Support OTN performance monitoring and alarm monitoring functions. Provide the following monitoring functions: laser bias current monitoring, laser operating temperature monitoring, optical power monitoring, etc. With Ethernet RMON monitoring function. When accessing GE services and the encapsulation method is GFP-T (select the service type GE(GFP-T) on the NMS), it supports TC mode, TC +OC mode, BC mode and OC mode. When accessing OTU1 service, it supports BC mode and OC mode. When accessing GE (GFP-T) services, the “TX8” / “RX8” optical ports do not support the processing of IEEE 1588v2 clock signals. When accessing OTU1, it only supports the frequency synchronization through the sending and receiving timestamp information of IEEE 1588v2 Sync messages, and does not support the frequency synchronization through the physical layer clock.
