How to Configure the Fast Path Mode for the VDSL Line Profile of an Huawei DSLAM MA5616?

Our company just purchased an Huawei DSLAM MA5616 from oversea, how to configure the fast path mode for the VDSL line profile of an MA5616?

The mode of a VDSL line profile, interleaving path mode or fast path mode, is determined based on the values of the interleaving delay and impulse noise protection (INP). Therefore, configure the following parameters to determine the fast path mode:

• Set Maximum interleaving delay downstream/upstream to 0.
• Set Maximum INP on downstream/upstream direction to 1, which indicates that no protection is enabled.
• Set Minimum rtxratio/rsoverhead in downstream/upstream to 0.

The commands are as follows:

What is the All-in-one Highlight of Huawei OLT MA5600T?

The integrated fiber-copper access platform and the access-aggregation integration capability of Huawei MA5600T/MA5603T/MA5608T effectively ensure the smooth evolution of the access network.

Huawei MA5600T/MA5603T/MA5608T supports integrated fiber-copper access and access-aggregation integration

MA5600T/MA5603T/MA5608T of the all in one platform 

Fiber-Copper Integration

The MA5600T/MA5603T/MA5608T enables optical fibers and copper lines to be integrated in one platform, which ensures that the access network can smoothly evolve from copper line access to optical fiber access.

• Optical fiber access: The MA5600T/MA5603T/MA5608T supports GPON, 10G GPON, and P2P optical fiber access, satisfying the requirements of the FTTH, FTTB, FTTC, FTTO, FTTM, and FTTW scenarios.
• Copper line access: The MA5600T/MA5603T/MA5608T supports ADSL2+ (compatible with ADSL), VDSL2 (compatible with ADSL2+), SHDSL, and POTS voice services. The MA5600T/MA5603T/MA5608T supports multiple copper line access modes and makes full use of existing copper line resources to provide users with rich and flexible network services. In addition, the MA5600T/MA5603T/MA5608T can function as a DLSAM to be used in copper access only, or as an MSAN to be used in integrated fiber-copper access.

Access-Aggregation Integration

The MA5600T/MA5603T can implement FTTH/DSLAM access and FTTB/FTTC/DSLAM Ethernet aggregation in the same subrack to provide a unified traffic aggregation point on the FTTH/FTTC/FTTB/FTTD network, thereby achieving aggregation of different network construction modes, eliminating the need to construct an independent access-aggregation network layer, and simplifying the network architecture.

• The MA5600T supports a maximum non-aggregation forwarding capability of 40 Gbit/s x 16 GE.
• The MA5600T and MA5603T support the 48-port high-density aggregation board and provide access for a maximum of 768 GE ports.
• The OLT supports Layer 3 functions and can be used as an aggregation edge device. It possesses powerful Layer 3 service processing capabilities, such as 40G switching capability and 60 Mpps Layer 3 forwarding capability in the 8 x 10 GE upstream load-sharing mode. With these capabilities, the OLT can:
  • Reduce upper-layer service traffic and shorten network transmission delay. Specifically, the OLT can perform Layer 3 switching for local traffic, thereby lowering the traffic pressure of the upper-layer network and pressure of network traffic expansion.
  • Simplify the network architecture. Specifically, Layer 2 aggregation switches do not need to be deployed, thereby streamlining the network layers.
  • Improve network security. Specifically, the upper network does not learn the user-side MAC addresses, thereby eliminating the risks of MAC spoofing and broadcast storms.
• The MA5600T and MA5603T support the mature all-service MPLS solution.
• Huawei MA5600T and MA5603T support service transmission over ATM PWE3, TDM PWE3, ETH PWE3, VPLS, and L2VPN.
• The MA5600T and MA5603T feature high service performance. Specifically, they support quick E2E service protection (service switching time: ≤ 200 ms).
• The MA5600T and MA5603T do not have limitations on service authentication and terminal VLAN planning, simplifying network design and maintenance.

What Is the Relationship Between the LOF and LOS Alarms?

How to detect LOF and LOS alarms and what is the relationship between these two alarms? What alarm is generated if optical fibers are removed when the Huawei MA5606T or MA5652G serves as an Huawei ONU?

LOF indicates loss of frame. When such an alarm is generated, the ONU can receive optical signals. LOS indicates loss of signal. When such an alarm is generated, the ONU fails to receive optical signals. The mechanisms of detecting LOFi and LOSi alarms are as follows:

• LOFi: If four consecutive frames of an OLT fail to locate an upstream frame of an ONU, the LOFi alarm is generated and the ONU goes offline.
• LOSi: If four consecutive frames of an OLT MA5600T fail to receive an upstream optical signal of an ONU, the LOFi alarm is generated and the ONU goes offline.

The relationship between the LOF and LOS alarms is as follows:

• Use an optical attenuator to test the ATM 155/622 Mbit/s optical port and increase the attenuation gradually. It is found that the alarm status changes as follows: normal -> SD -> LOF -> LOS. This indicates that after LOF is generated, if the attenuation is increased further, no optical signal is received and LOS is generated. If an optical fiber is removed, LOF may be generated first and then LOS, which is related to the alarm detection mechanism. The LOSi, LOFi, and LCDGi alarms are detected in the time window mode. In the first several detections, if the time window detects the threshold for frame losing, the LOFi alarm will be generated.
• If the PON line generates an LOF alarm, LOS will not be generated. This is because the PON port uses the time division system. If an LOF alarm is generated, the ONT goes offline and then the OLT does not assign the timeslot (bandwidth) to the ONU. Therefore, the OLT does not detect whether the ONT transmits upstream optical signals and an LOS alarm is not generated.
• If LOS is generated, LOF/SD will be suppressed. This is because LOS is the alarm of the highest severity.

When the MA5606T and MA5652G serve as an ONU MA5628 and the optical patch is normal, LOS is generated when an optical fiber is removed.

Huawei MA5800 Alarms and Events Handling

FAQs of Document Use When Handling Huawei MA5800 Alarms and Events 

This alarm and reference document, if used flexibly, can help you to rectify the faults quickly, thus improving maintenance efficiency and facilitating the management of alarms and events in the system.

Q1: How to enter the special CLI mode

A1: The following considers the FAN mode as an example to describe how to enter the FAN mode:

1. Click a command in the steps.
   
   
2. In the interface that is displayed, you can see the mode of the command. The User Guide describes how to enter this mode.

Q2: Why is the recovery alarm not displayed after the fault is rectified

A2: The following situations may occur:

• This alarm is an ADMC alarm caused by an ADMC fault. After the ADMC fault is rectified, the system does not generate a recovery alarm. Therefore, manual operations are needed. You can run the alarm active clear command to clear the alarms that are not recovered in the system.
• The system checks the faults periodically. The system generates a recovery alarm only after detecting that the faults are rectified.

Q3: How to search for an alarm or event in the document

A3: You can follow one of the following two methods to search for an alarm or event.

• Search for an alarm or event according to the alarm ID or the event ID.
• Search for an alarm or event according to the name of the alarm or event.
