MA5616 ADSL2+ VDSL2 Board Introduction and Comparison

Huawei MA5616 is an industry-leading remote multi dwelling unit (MDU), supports flexible configurations, The MA5616 provides two GPON or GE uplink ports and provides multiple services by supporting flexible board configurations. MA5616 provides broadband, voice, and video services through ADSL2+/ VDSL2/FE boards, voices service through POTS boards, leased line services through SHDSL or P2P boards.

ADSL VDAL Application

This article will mainly introduction the ADSL2+ VDSL2 boards supported on MA5616 and what are the difference of these boards.

 

What is VDSL2?

Very high-speed digital subscriber line (VDSL) and very high-speed digital subscriber line 2 (VDSL2) are digital subscriber line (DSL) technologies providing data transmission faster than asymmetric digital subscriber line (ADSL).

VDSL offers speeds of up to 52 Mbit/s downstream and 16 Mbit/s upstream, over a single flat untwisted or twisted pair of copper wires using the frequency band from 25 kHz to 12 MHz. Second-generation systems VDSL2 use frequencies of up to 30 MHz to provide data rates exceeding 100 Mbit/s simultaneously in both the upstream and downstream directions. The maximum available bit rate is achieved at a range of about 300 meters.

Differences Between MA5616 VDSL2 Service Boards

Based on the number of supported users, VDSL2 service boards supported by the MA5616 can be classified into 5 types of channel:

16-channel VDSL2 service board

24-channel VDSL2 service board

32-channel VDSL2 service board

48-channel VDSL2 service board

64-channel VDSL2 service board.

These boards support VDSL2 and VDSL2 over POTS/ISDN access services.

NOTE:

  • When AC power supply is used, the H83BVDMM board must work with the H831PAIC power board.
  • Users can switch a configuration mode. To do so, log in to the MA5616 as a super user and run the switch vdsl mode to command in diagnose mode. The default configuration mode is TR129. Considering the development trend, TR165 is recommended because it is more flexible than others.
  • Vectoring-supported service boards take effect only when they work with power boards supporting vectoring.
  • H83BVCLEsupports Vectoring, while H836VCLE does not support.

 

What is ADSL2+?

Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ADSL differs from the less common symmetric digital subscriber line (SDSL). In ADSL, bandwidth and bit rate are said to be asymmetric, meaning greater toward the customer premises (downstream) than the reverse (upstream).

Differences Between ADSL2+ Service Boards

Based on the number of supported users, ADSL2+ service boards supported by MA5616 can be classified into 32-channel ADSL2+ and 64-channel ADSL2+ service board. These boards support ADSL2+ and ADSL2+ over POTS access services.

Supports RFC 2662, RFC 4706, and TR165. (Users can switch a configuration mode. To do so, log in to the MA5616 as a super user and run the switch adsl mode to command in diagnose mode. The default configuration mode is RFC 2662. Considering the development trend, TR165 is recommended because it is more flexible than others.)

As we can see, ADSL2+ boards has no vectoring function, just VDSL board H83BVCLE H83BVCLF H83BVCMM H83DVCMM H83DVCPE can support;and if you acquire MA5616 support vectoring, please make sure that the MA5616 power board configured support vectoring. Only below 3 type of power boards support vectoring.
