CCUA: It is a centralized control unit of the MA5610. Through the service board configuration, the MA5610 supports up to 256 POTS ports or 48 FE port for user access.
CCUB: It is a centralized control unit of the MA5616. Through the service board configuration, Huawei MA5616 supports up to 256 POTS ports or 128 ADSL2+ ports for user access.
2. Daughter board supported by the CCUA/CCUB board
The CCUA/CCUB board, configured with different daughter boards, can provides one EPON, GPON, or GE upstream port, and one GE optical or electrical subtending port Only one CCUA/CCUB board can be configured on the MA5616, and it is hot swappable.
The CCUA/CCUB board supports the GP1A, EP1A, GE1A, and ASDA daughter boards.
The GP1A daughter board provides one GPON port and one GE optical port.
The EP1A daughter board provides one EPON port and one GE optical port.
The GE1A daughter board provides two GE optical ports.
The ASDA daughter board is of the POTS DSP type, and it is configured when the POTS service is supported. When the voice service is not used, this daughter board may not be configured. When it is not configured, the voice service board (Huawei ASPB board or ASRB) cannot be registered.

3. CCUA/CCUB upstream transmission or subtending (the following port IDs are IDs displayed in the CLI)
Note: Ports 0 and 1 on the CCUA/CCUB board are displayed as ports 1 and 0 in the CLI. In addition, the default VLAN of the port cannot be set.
(1) When the CCUA/CCUB board is configured with the GP1A or EP1A daughter board, port 0 is a GE port, and port 1 is a PON port. The PON port is used for upstream transmission, and the GE port can be used for either upstream transmission or subtending. In this case, three upstream transmission modes are supported: upstream transmission through the PON port, through the GE port, and through both the GE port and the PON port.
When you want to use the GE port for upstream transmission, run the network-role 0 uplink command to set the GE port as the upstream port.
In hardware, GE port 1 corresponds to two GE ports, one optical and one electrical, which share one internal channel. Only one can be used, corresponding to port 0 in the CLI. You can run the combo-mode 0 optic/electric command to switch between optical and electrical, and also you can set the mode as autoadaptation , which means that the system automatically chooses one.
(2) When the GE1A daughter board is configured, the MA561x functions as a DSLAM. Port 1 is used for upstream transmission, and port 0 can be used for either upstream transmission or subtending. The configuration method is the same as that in the first condition (configured with the GP1A or EP1A daughter board).
(3) The two GE ports on the GE1A daughter board support aggregated upstream transmission.
Note: Ports 0 and 1 on the CCUA/CCUB board are displayed as ports 1 and 0 in the CLI. In addition, the default VLAN of the port cannot be set.
