Huawei MDU MA5623

Vectoring Broadband Service Speedup

The MA5622A and MA5623A support the Vectoring technology to increase the very-high-speed digital subscriber line 2 (VDSL2) ρυθμός γραμμής.

ΣΗΜΕΙΩΣΗ:

Only the MA5622A and MA5623A support the Vectoring.

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 Vectoring technology 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 MA5622A/MA5623A helps cancel the far-end crosstalk (FEXT) and improve the performance of a VDSL2 line.

Operable IPTV Service

Supports Internet Group Management Protocol (IGMP) v2 and v3 to provide IPTV, high definition TV, and video conference services.

IPv6

• ο MA5622A/MA5623/MA5623A supports Internet Protocol version 6 (IPv6). Compared with IPv4, IPv6 features simplified packet header format, sufficient IP addresses, hierarchical IP address structure, flexible extension header, and enhanced neighbor discovery mechanism.
• Supports IPv6 address management and allocation, IPv6 routing, quality of service (QoS) και ασφάλεια, Στρώμα 2 transparent transmission, and multicast services.

One-Site Deployment and Plug-and-Play

• Is free of software commissioning on site.
• Supports offline deployment and plug-and-play.
• Automatically obtains configuration data from the iManager U2000 network management system (U2000) and reports its status to the U2000 after going online. The configuration data automatically takes effect.

Zero Touch Routine Maintenance

• Supports remote fault location and troubleshooting.
• Supports remote acceptance.
• Supports remote upgrade and patch installation.

Σχεδιασμός αξιοπιστίας Carrier-Class

• Συμμορφώνεται με τις προδιαγραφές αξιοπιστίας κατηγορίας φορέα.
• Περνάει την ηλεκτροστατική εκφόρτιση (ESD) δοκιμή.
• Be able to start at a -25°C temperature and to work properly for extended periods of time at a temperature as low as -40°C.
• Be able to work properly at a temperature as high as 65°C (temperature at the air intake vent of the cabinet) for extended periods of time.
• Παρέχει προστασία από υπερτάσεις και λειτουργίες κατά των παρεμβολών.
• Supports user port protection as follows: 4 kV in common mode and in differential mode
• Supports power protection as follows:
  • DC ισχύς: 5 kV in common mode and 3 kV in differential mode
  • Ισχύς AC: 6 kV/5 kA in common mode and 6 kV/3 kA in differential mode
• Uses an anticorrosion design, reduces the wires routed across the surface of the board, and optimizes the heat design by producing a temperature difference to prevent condensation.
