Types of supervisory channels supported by NG WDM equipment
The DCC channel bandwidth supported by NG WDM equipment is represented by the number of loadable 64 bytes. The following lists the DCC channels supported by NG WDM equipment and the bandwidth: D1-D3 3 bytes D4-D12 9 bytes GCC0 3 bytes GCC12_9 9 bytes GCC12_18 18 bytes Pilot-tone DCC Irrelevant to byte or bandwidth Note: 1. For the OTU boards whose WDM-side service type is SDH, the DCC channel type is D1-D3. Channels D4-D12 are not supported. 2. SC2/SC1 boards support two DCC channel types: D1-D3 and D4-D12. In normal situations, both DCC channel types can be used to transmit monitoring information. After ASON is enabled, D4-D12 can be used only as physical channels to transmit the ASON protocol. 3. For the OTU board of the OTN frame structure, three channel types are supported: GCC0, GCC12_9, and GCC12_18. For OTN boards with 2.5G rates, GCC0 and GCC12_9 are allocated. For OTN boards with 5G and 10G, GCC0 and GCC12_18 are allocated. The bandwidth provided by GCC0 is 3 bytes, which is the same as the bandwidth of D1-D3. It is the GCC0 byte in the OTUk overhead in the OTN frame structure. The bandwidth provided by GCC12_9 and GCC12_18 are 9 and 18 bytes respectively. They are the GCC1 and GCC2 bytes without various bandwidth in the ODUk overhead in the OTN frame structure. 4. Pilot-tone DCC is special. By coupling RF signals and service signals, pilot-tone DCC uses RF signals to carry monitoring information. Therefore, no byte or bandwidth is involved in pilot-tone DCC.

Whether Huawei NG WDM products support 16 CWDM wavelengths
Huawei NG WDM products support only eight CWDM wavelengths, but some optical-layer boards such as CMR2 and CMR4 support up to 16 wavelengths. Among the 16 wavelengths, eight are provided by NG WDM products and the other eight are provided by third-party equipment.

Whether the IP address of a WDM NE varies according to the NE ID
If the IP address of an NE is not changed before you change the NE ID, the IP address of the NE varies according to the NE ID. The association between the NE ID and IP address will be automatically released once you manually change the NE IP address. In other words, the NE IP address will not vary according to the NE ID after the NE IP address is manually changed.
