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.
