Support Annex A/L/M

ADSL2+ (ITU G.992.5) doubles the bandwidth used for

downstream data transmission, which effectively doubles

the maximum downstream data rates, to achieve rates up to

20 Mbps on telephone lines as long as 1,524 meters. ADSL2+

solutions will interoperate with ADSL, ADSL2 and ADSL2+.

ADSL2+ includes all the feature and performance benefits

of ADSL2 while maintaining the capability to interoperate

with legacy ADSL equipments.

The demand for greater bandwidth for Internet never stops

rising. No matter it’s for multimedia applications or a more

cost-effective means for enterprise connectivity, vendors

are not only expanding their lineup with new models, they

are adding value with new features as well. Today, ADSL2+

is the mainstream xDSL modem technology and the most

deployed one in the world.

ADSL2+ provides Internet access via standard copper

phone lines while it still allows users to make phone calls

over the same line. ADSL2+ boosts this to 24 Mbps over the

same phone lines and connection distance of up to 1,828.8

meters.

ZyXEL targets the MSAN and ADSL2/2+ CPE functionalities

at improving performance, interoperability and supports

to new applications, services and deployment scenarios.

Among the changes are improvements in data rate and

reach performance, rate adaptation, diagnostics and stand-

by mode, etc.

The main “Better Rate and Reach” enhancement of ADSL2/2+

improves modulation efficiency, reduces framing overhead,

achieves higher coding gain, improves the initialization

state machine and provides enhanced signal processing

algorithms.

ZyXEL offers a complete end-to-end ADSL2+ solution with

Annex A/B/L/M. Annex L can extend the coverage distance

to up to 609.6 meters, while Annex M can support doubled

upstream bandwidth of ADSL2+ Annex A/B.
