XL-GDB SHDSL series Executive Summary
Today’s bandwidth requiremenrt applications, such as Internet access, remote LAN access,
teleconferencing, workgroup and data sharing, telecommuting and numerous varieties of digital
video services and the increasing volume of traditional data, are driving demand for high-speed
data network access.
We, XTENDLAN, design, develop and market transmission systems based on Digital
Subscriber Line (DSL) technology for copper wire plant. They support all contemporary data
rates, from 64kbps to multi-megabit symmetric and asymmetric transmission for voice, video
and data communications over a twisted copper pair. Our access systems link enterprise LANs
and Network Service Providers over private and public networks across the local loop, the
connection between the customer and the first network node.
Deploying in nearly any symmetric application requiring bandwidths from 192kbps to 2.3Mbps,
G.SHDSL is poised for the best cost-effective solution for business-based applications such as
Internet access and remote LAN access. By adapting G.SHDSL, Small to Medium Enterprises
(SME) no longer afford the expensive enterprise data solutions such as T1/E1.
XL-GDB
offers
Telcom service providers the best cost-effective solution for immediate implementation of
replacing T1/E1 leased line.
XL-GDB
provides full duplex capability of supporting selected symmetric user data rates of T1, E1
or n x 64 kbit/s (range from 192 kbit/s to 2 304 kbit/s) leased line services or Ethernet interface
extension using a Trellis Coded Pulse Amplitude Modulation (TCPAM) line code over one
non-loaded two-wire metallic cable pair. The line speed for transmitted and received data shall be
multiple for lengthening the transmission distance. These selectable line rates empower Telecom
to create high-bandwidth service offerings or select the proper speed for distance-sensitive
deployments, thereby deploiting the high-bandidth efficiently and fitting subscribers’ needs
simutaneously.
