Digital Subscriber
Line (DSL) is a modem technology that turns your
existing phone line into data, voice and video delivery system.
 DSL
provides high-speed digital modem technology via a conventional
analog telephone line. DSL signal does not
interfere with analog telephone conversations or facsimile
transmissions. DSL uses signal frequencies
above those used by analog voice or faxes.
DSL is a distance-sensitive modem technology
that works solely over copper phone lines. When you connect
to the Internet using a DSL modem, the speeds that you will
experience depend upon a variety of factors, including the
following:
· Distance of your telephone line from a Carrier Central Office.
· Condition of the telephone wiring inside and outside your
location.
· Your Computer configuration.
· Network or Internet congestion.
· Routers, Switches and Servers speeds of the Carrier Side
and Web Sites you access.

availability for any of your telephone numbers by going to:

1.
Asymmetric Digital Subscriber Line (ADSL) is designed
to deliver more bandwidth downstream (from the central office
to the customer site) than upstream. Downstream rates range
from 1.5 to 9 Mbps, whereas upstream bandwidth ranges from
16 to 640 kbps. ADSL transmissions
work at distances up to 18,000 feet (5,488 meters) over a
single copper twisted pair.
2.
High-Data-Rate Digital Subscriber Line (HDSL)
delivers 1.544 Mbps of bandwidth each way over two copper
twisted pairs.
HDSL
provides T1 speed. The operating range of HDSL is limited
to 12,000 feet (3658.5 meters) and signal repeaters are needed
to be installed to extend the service.
HDSL requires two twisted pairs, so it is deployed
primarily for PBX network connections, digital loop carrier
systems, inter-exchange POP's, Internet Servers, and Private
Data Networks.
3.
ISDN Digital Subscriber
Line (IDSL), developed by Ascend Communications (acquired
by Lucent Technologies), transmits data digitally across existing
ISDN lines, at a rate of 128 Kbps. The benefits of
IDSL over ISDN are:
b)
ISDN service offers always-on connections and
transmits data via a data network.
A)
IDSL (ISDN
Digital Subscriber Line) transmits data via the phone
company's voice network, and avoids per-call fees by being
billed at a flat-rate.
4. Long Range Ethernet
(LRE) solution, developed by
Cisco Systems, leverages
Very High Data Rate Digital Subscriber Line (VDSL)
technology to dramatically extend Ethernet services over existing
Category 1/2/3 twisted pair wiring at speeds from 5 to 15
Mbps (full duplex) and distances up to 5,000 feet.
Long Range Ethernet (LRE)
technology, developed by Cisco
Systems, delivers broadband service on the same
lines as Plain Old Telephone Service (POTS), digital telephone,
and ISDN traffic. In addition, Long Range Ethernet
(LRE) technology, developed by Cisco
Systems, supports modes compatible with Asymmetric
Digital Subscriber Line (ADSL) technologies, allowing service
providers to provision LRE
to buildings where broadband services already exist.
