H801MCUD1 Board
The H801MCUD1 board is a mini control unit board. It is the core of the system control and service switching and aggregation. The H801MCUD1 board can also function as the management and control core of the integrated network management system (NMS). It communicates with service boards about the key management and control information through the master/slave serial port and inband GE/10GE channel. In this manner, the H801MCUD1 board configures, manages, and controls the device, and also implements the simple route protocol functions.
Feature and Specifications
MCU Boards Comparison
All MCU boards support the functions as below:
System control and management unit
Active/standby switchover and load sharing
Local and remote maintenance through maintenance serial port CON or maintenance Ethernet port ETH
Environmental monitoring
Synchronization with the Ethernet clock
Temperature querying and high temperature alarming
Monitoring and management of the fan tray
Seven alarm digital inputs (DIs) and one alarm digital output (DO)
Copper and optical access
In the table, "Yes" indicates "supported" and "No" indicates "not supported".
Table 1 Major differences between MCU boards
Board | One input of BITS clock signals and one output of BITS clock signals | One input of 1PPS+TOD time signals and one output of 1PPS+TOD time signals | Stratum-3 clock | D-CMTS cluster management |
H801MCUD1 | Yes | Yes | Yes | No |

Parameters
Power Consumption and Maximum Frame Size of Boards
You can query power consumption, maximum frame size, and normal operating temperature of all boards.
lists the power consumption and maximum frame size of boards. "-" indicates N/A.
The operating temperature of all the boards is -40°C to +65°C. The lowest board startup temperature is -25°C.
NOTE:
The power consumption of the board is tested in the following conditions:
Working voltage: -53.5 V DC.
Ambient temperature: 25 °C.
Static power consumption: All ports do not carry any loads. Specifically, users under POTS ports hang up phones, xDSL ports are deactivated, and optical modules are not installed on optical ports
Maximum power consumption: All ports fully carry loads. However, only 25% users under POTS ports concurrently pick up phones and the feeding current is 20 mA.
The board power consumption slightly varies with the power module configured for the board and discreteness of components.

Board | Power Consumption | Maximum Frame Size |
Control board (MCU) | ||
H801MCUD1 | Static: 29 W Maximum: 33 W | 2052 bytes. After the jumbo frame function is enabled, a maximum of 9216 bytes can be supported. |
Working Principle
The basic working principles of the H801MCUD1 board are as follows:
The control module manages the entire board and the service boards.
The logical module achieves the logical control and stratum-3 clock functions.
The power module supplies power to other functional modules of the board.
The clock module provides clock signals for other functional modules of the board.
The switching module provides the GE port and the 10GE port to switch and aggregate services at Layer 2 or Layer 3.
Providing two GE/10GE ports or two GE ports for upstream transmission of the upstream port on the front panel
Providing two GE/10GE ports for implementing GE/10GE switching on each service board
