Common questions about extended ECC on WDM NEs
Question: How many NEs can be interconnected using automatically extended ECC at a site? Analysis: At many sites, all NEs are interconnected using automatically extended ECC. As a result, there is a large number of NEs using this function for interconnection, and NEs are frequently unreachable by the NMS. Answer: 1. If an Ethernet is used to establish an extended ECC channel for communication, at most four extended ECC channels are required. With manually extended ECC, a server can be connected to at most 7 clients, and each client can be further connected as a server. Hubs (or switches) can be cascaded, which is related to the network scale limit only. The basic principle applies to each product and is related to the platform. 2. The method of cascading metro WDM devices using ETHERNET1 and ETHERNET2 ports does not apply to a long-haul WDM system. For long-haul WDM devices, the ETHERNET2 port is not used for ECC communication. In addition, you are advised to cascade at most eight network ports in a metro WDM system.

Differences between manually extended ECC and automatically extended ECC
1. In terms of functionality, there is no difference between manually extended ECC and automatically extended ECC. Automatically extended ECC is used by default. 2. Manually extended ECC is recommended when there are more than four NEs.

Method used to configure extended ECC in a slave subrack and method used to connect network cables to achieve extended ECC communication
The NM_ETH port of a slave subrack is disabled by default and is not used for inter-NE communication. Inter-NE communication is implemented only through the NM_ETH port of a master subrack.
