TNG1M520S	TNG1M520SM	Version substitution	During board substitution using the version replacement function, the NE where the original board resides does not need to be upgraded. The substitute board can be created as the logical board of the original board on the NMS and replace the original board. The substitute board has only the functions of the original board. During board substitution using the version replacement function, because the original board and substitute board support the same optical modules, the optical modules of the original board can still be used.

Supports the PRBS test function in the backplane direction when other services are received on the tributary side. Supports the PRBS test function on the line side.
Latency measurement	Supports PM and TCM latency measurement for upstream higher-order ODU channels. Supports PM and TCM latency measurement for upstream lower-order ODU channels when non-OTN services are received on the client side. Supports TCM latency measurement for downstream lower-order ODU channels when OTN services are received on the client side. NOTE: In a mapping path, the maximum granularity ODUk channel is the higher-order ODU channel, and other ODUk channels are lower-order ODUk channels.
Channel loopback	100G line: supports ODU0/ODU1/ODU2/ODU3/ODUflex/OSUflex channel inloop and outloop. 200G line: supports ODU0/ODU1/ODU2/ODU3/ODU4/ODUflex/OSUflex channel inloop and outloop. NOTE: The board does not support the channel loopback and ODUk loopback at the same time. When a client-side port accesses 4 x 10GE signals, only channel loopback is supported. When cross-connections are set up between the client-side port and the line side of the board only, channel loopback is not supported.
Port loopback	Supports inloops and outloops on the WDM side. Supports inloops and outloops on the client side. Supports ODUk inloops and ODUk outloops on the client side. NOTE: when cross-connections are created between the port and the line side of this board and between the port and the line side of other boards, the port does not support the SNCP protection and port inloop loopback at the same time. Client-side loopback is not supported when the port accesses 4 x 10GE LAN signals. When the board functions as an OTU board, the line-side rate is 100 Gbit/s, and the client-side accesses 100GE/OTU4 services, WDM-side loopback is not supported. When no cross-connection is configured on a client-side port, inloops cannot be configured on the client-side port.
Alarm and performance event monitoring	Supports the monitoring of BIP8 bytes (Bursty mode) to help locate line failures. Supports the monitoring of OTN alarms and performance events. Supports the remote monitoring (RMON) of Ethernet services. Supports the monitoring of the bias current of the laser. Supports the monitoring of the temperature of the laser. Supports the monitoring of the optical power.
