Huawei DSLAM MA5616 Power Distribution Principle and Working Principles

Power Distribution Principle

Huawei MA5616 can be powered by a DC or AC power source through a DC or AC power board. The power board outputs -48 V DC, +3.3 V DC, and +12 V DC power to the backplane. Then the backplane provides the -48 V DC and +3.3 V DC power for the service board and control board, and provides the +12 V DC power for the fan monitoring board.

Working Principles

Huawei MA5616 supports GPON, 10G GPON or GE upstream CCUE transmission by using its control board and provides broadband and narrowband access services by using different service boards.

Working principles of the MA5616 chassis 

The working principles of Huawei DSLAM MA5616 chassis are as follows:

• The control board transmits services upstream and subtends device through subboards and manages service boards.
• The power board outputs DC power to the backplane and then the backplane transmits the power to the fan tray, service boards, and control board.
• The broadband or narrowband service board is connected to a user-side device by using a subscriber cable, and then the control board puts the user-side device through to the IP network. In this way, broadband or narrowband access service is provisioned to the user-side device.
• The fan monitoring board monitors the fan tray and transmits the monitoring signal to the control board through the backplane.

Do you know the features of Huawei DSLAM MA5616?

10G GPON Upstream Transmission

• 10G GPON provides a higher bandwidth to meet service requirements.
• The 10G GPON transmission complies with ITU-T Recommendation G.987 and ITU-T Recommendation G.988, and provides asymmetric transmission rates of 2.5 Gbit/s in the upstream direction and 10 Gbit/s in the downstream direction.
• 10G GPON networks can coexist with the current GPON networks to fully use the existing optical distribution network (ODN) resources.

Vectoring Broadband Service Speedup

Huawei MA5616 supports the vectoring technology to increase the very-high-speed digital subscriber line 2 (VDSL2) line rate.

VDSL2 is a mainstream mode for last kilometer access and shows increasing importance in bandwidth usage. VDSL2 uses high frequency bands and therefore the inter-line crosstalk has an evident impact on line quality. The bandwidth in multi-pair access scenario is much lower than the bandwidth in single-pair access scenario. Crosstalk becomes a major factor affecting the VDSL2 performance.

The MA5616 supports the vectoring technology, which uses vectoring groups to jointly transmit signals in the downstream direction and receive signals in the upstream direction of a VDSL2 line. This function of the MA5616 helps cancel the far-end crosstalk (FEXT) and improve VDSL2 line performance.

The vectoring function brings the following values for carriers:

• Increases the bandwidth over a single cable within 500 m by 50% to 90%, reaching 95% of the theoretical value (without crosstalk).
• After rate increasing, carriers can provide higher rates and more types of services for users, such as high-definition video.

NOTE:

Only when the system uses the CCUE control board, the MA5616 supports vectoring broadband service speedup.

Flexible Configurations

The MA5616 supports concurrent working of multiple types of service boards. Numbers of various ports are configured flexibly according to actual requirements, increasing the loading rate and meeting diversified customer demands. For details about the flexible configuration supported by the MA5616

Combo Boards and P2P Board

The MA5616 has a combo board design for supporting a high subscriber density. Combo boards save carriers' construction expenditure, require less deployment space, wiring workload, and time occupancy of the main distribution frame (MDF). Briefly, combo boards reduce carriers' maintenance costs.

• The CALE board has a 32-port built-in splitter and supports service access of 32 asymmetric digital subscriber line 2 plus ADSL2+ ports and 32 plain old telephone service (POTS) ports.
• The CVLC board has a 32-port built-in splitter and supports service access of 32 VDSL2 ports and 32 POTS ports.

The MA5616 provides the following point-to-point (P2P) boards to meet the requirements of P2P access for enterprises and VIP users.

How to Query Traffic of a Port on Huawei MA5616?

How to Query Traffic of a Port on Huawei MA5616?

On current ONUs, you can query packet statistics of a port but cannot directly query traffic of a port. To obtain traffic of a port, you can collect the number of frames received or transmitted by the port in a period of time as follows:

1. Query the number of frames received or transmitted by a port at two different time points by running the following commands for different scenarios:
   • On a GPON uplink port, run the interface gponnni command to enter the GPONNNI mode, and then run the display gpon-port statistics command to query the number of frames received or transmitted by a port.
   • On other ports, run the display interface [ interface-type [ interface-number ] ] command to query the number of received or transmitted by the ports.
2. Use the following formula to calculate the number of frames received or transmitted by a port between two time points: Number of frames collected the second time - Number of frames collected the first time.
3. Use the following formula to calculate the traffic on the port: Number of frames x Bytes per frame.

For example, the number of frames on a port are collected at two time points within 30s, and the number of frames between the two time points is 85734 (786687061 - 786601327). Assume that the length of a frame is about 1500 bytes. The traffic on the port within 30s is 981 Mbits (85734 x 1500 x 8= 1,028,808,000 bits), or 122.6 Mbytes.

How to Configure the Auto-save Function for Huawei OLT

This topic describes how to configure the auto-save function so that the system configuration data or database files can be saved automatically. You can also make an reference for the MA5680T, MA5616, MA5608T, MA5603T, MA5600T.
Background Information
The MA5600 supports two auto-save modes:

• Auto-save at preset interval.
• Auto-save at preset time.

Pay attention to the following points:

• Auto-save at preset time conflicts with auto-save at preset interval. You can enable only one of them.
• Saving data frequently affects the system. Therefore, an auto-save interval shorter than one hour is not recommended, and it is recommended that you set the interval equal to or longer than one day.
• Before the system upgrade operation, run the autosave interval off or autosave time off command to disable the auto-save function to prevent upgrade failure due to the conflict between upgrade and auto-save operations.

 NOTICE:
After the system upgrade is completed, you must re-enable the auto-save function if the auto-save function is required.
Configuration Flowchart
Figure 1 shows the flowchart for configuring the auto-save function.
Figure 1 Flowchart for configuring the auto-save function

Procedure

• Configure auto-save at preset interval.
  1. In the global config mode, run the autosave interval on command to enable auto-save at preset interval.

Auto-save at preset interval conflicts with auto-save at preset time. You can enable only one of them.

2. (Optional) In the global config mode, run the autosave interval configuration command to set the auto-save interval for modified system data.

Auto-save is performed according to the interval set by the user. The system checks whether the system data is modified at each interval. If the system data is modified, the system saves the data. Otherwise, the system does not save the data. By default, the interval is 30 minutes.

3. (Optional) In the global config mode, run the autosave interval command to set the auto-save interval.

After the setting, the system data is automatically saved at the set interval regardless of whether the system data is modified. By default, the interval is 24 hours.

4. (Optional) Set the auto-save file type.

In the global config mode, run the autosave type command to set the auto-save file type.

• Configure auto-save at preset time.
  1. In the global mode, run the autosave time on command to enable auto-save at preset time.

Auto-save at preset time conflicts with auto-save at preset interval. You can enable only one of them.

2. (Optional) In the global config mode, run the autosave time command to set the auto-save time.

After the setting, the system data is automatically saved at the set time regardless of whether the system data is modified. By default, the time is 00:00:00.

3. (Optional) Set the auto-save file type.

In the global config mode, run the autosave type command to set the auto-save file type.
Example
To enable auto-save at preset interval on the MA5600, set the auto-save interval to two days (2880 minutes), and save both the database file and the configuration file, do as follows:
huawei(config)#autosave interval on
huawei(config)#autosave interval 2880
huawei(config)#autosave type all
huawei(config)#save
