Huawei MA5600T supports the VoIP service only when the electronic switch is already switched to the VoIP daughter board. By default, Huawei MA5600T does not support the VoIP service.
Since V800R005, the VoIP service has been supported.
The MA5600T provides the following two electronic switches:
- Electronic switch 0: Used for determining whether the port on the control board or the port on the upstream interface board of the MA5600T is used for upstream transmission.
- If the electronic switch is on location-0, it indicates that the control board is used for upstream transmission.
- If the electronic switch is on location-1, it indicates that the upstream interface board is used for upstream transmission.
- By default, electronic switch 0 is on location-0.
- Electronic switch 1: Used for determining whether Huawei OLT supports the VoIP service or supports upstream transmission through port 0/20/3.
- If the electronic switch is on location-0, it indicates that the electronic switch is switched to the VoIP daughter board and thus supporting the VoIP service.
- If the electronic switch is on location-1, it indicates that the electronic switch is switched to port 0/20/3. Then, port 0/20/3 serves as the upstream port.
- By default, electronic switch 1 is on location-1, indicating that the VoIP service is not supported.
- The SCUL OLT main control board does not support the VoIP service and does not provide the upstream port; thus, services are upstream transmitted by only the upstream interface board.
- The SCUL control board does not support the electronic switch
