OUR COMPANY HAS A DREAM AND VISION OF ALL IP CONVERGENCE

DSL (Digital Subscriber Line) is a technology for bringing high-bandwidth information to homes and small businesses over ordinary copper telephone lines. xDSL refers to different variations of DSL, such as ADSL, HDSL, VDSL and RADSL. Assuming your home or small business is close enough to a telephone company central office that offers DSL service, you may be able to receive data at rates up to 6.1 megabits (millions of bits) per second (of a theoretical 8.448 megabits per second), enabling continuous transmission of motion video, audio, and even 3-D effects. More typically, individual connections will provide from 1.544 Mbps to 512 Kbps downstream and about 128 Kbps upstream.

A DSL line can carry both data and voice signals and the data part of the line is continuously connected. DSL installations began in 1998 and will continue at a greatly increased pace through the next decade in a number of communities in the U.S. and elsewhere. Compaq, Intel, and Microsoft working with telephone companies have developed a standard and easier-to-install form of ADSL called G.Lite that is accelerating deployment. DSL is expected to replace ISDN in many areas and to compete with the cable modem in bringing multimedia and 3-D to homes and small businesses.  


G.hn(Gigabit Home Network) 

 

The explosive growth in network service devices such as smartphones, smart TVs, and UHD IPTVs has been paralleled in a correspondingly dramatic growth in the demand for high quality and high capacity multimedia content. The consequence is an instantaneously apparent increase in broadband Internet speeds 3~5 times faster, from 100 Mbps to 500 Mbps.
However, maximum broadband speeds are 100 Mbps for home users, regardless of the service they are using, whether it be VDSL2, LAN or FTTH. For these home users living in apartment complexes with existing phone line-based (VDSL2) and UTP-based (Cat5) Internet services to have access to Giga-class internet, their home broadband access needs to be as fast as hundreds of Mbps.


ubiQuoss has successfully addressed this concern with its G.hn solution, which is the world’s first to achieve maximum performance with reduced interference in bundled cables. A G.hn network consists of a GAM (G.hn Access Multiplexer) connected to the broadband backbone and a GNT (G.hn Network Terminal) installed at the user side; in essence, the G.hn solution requires only the existing VDSL equipment (DSLAM/modem) to be switched to Giga-class equipment (GAM/GNT), making it a cost-effective and viable solution.


VDSL2(Very high-data rate Digital Subscriber Line ver.2) 

 

VDSL2 is an enhancement to very-high-bit-rate digital subscriber line (VDSL), Recommendation G.993.1, and is the newest and most advanced currently deployed standard of digital subscriber line (DSL) broadband wireline communications. Designed to support the wide deployment of triple play services such as voice, video, data and high-definition television (HDTV) VDSL2 is intended to enable operators and carriers to gradually, flexibly, and cost-efficiently upgrade existing xDSL infrastructure.


VDSL2 permits the transmission of asymmetric and symmetric aggregate data rates up to 300+ Mbit/s downstream and upstream on twisted pairs using a bandwidth up to 35 MHz. It deteriorates quickly from a theoretical maximum of 350 Mbit/s at source to 100 Mbit/s at 0.5 km (1,600 ft) and 50 Mbit/s at 1 km (3,300 ft), but degrades at a much slower rate from there, and outperforms VDSL. Starting from 1.6 km (1 mi) its performance is equal to ADSL2+. 

G.hn Access Multiplexer

U4124B
Details

Overview

 

G.hn is ITU-T G.9960 and G.9961 Standards-based technology specialized for existing home connectivity infra such as Phone Line, Power Line and Coax Cable. U4124B provides unidirectional max. 500Mbps throughput at best while reducing investment and maintenance cost by utilizing the existing wired connection in houses.

 

U4124B can be used for broadband access network. It enables the premium quality services such as VOD, IPTV or VoIP through the existing phoneline connections and provides the high-speed data service and telephone service at the same time. It is the most efficient system which can be applied to multiple application environment such as small building, SOHO or individual house where data, voice and video are all in need simultaneously. The system provides services to all areas that phone line is available.
