DSL is the technology that converts ordinary telephone
lines into broadband data and telecommunications networks.
Network connections are the copper wires or twisted
copper pair that extend from the equipment located within
the local telephone exchange to your business premises,
and ultimately to your PC or Local Area Network. DSL
is the technology that converts this ordinary copper
pair to be capable of high speed data access.
Also part of your network connection is a DSL end point
device (to be included as part of your Internet
service that connects the twisted pair to your network
The network boundary device is normally a DSL capable
router. It connects to your PC or local area network
ensuring that wide area network traffic flows to the
Internet network, and vice versa.
Your network connection, and those of
other Internet customers, terminates in a connection
point, located in the local telephone exchange. The
Connection Point houses our Digital Subscriber Line
Access Multiplexers, or simply DSLAMs. A DSLAM multiplexes
your network traffic onto Internet's high-speed
"back haul" network, and on to the Internet
Point of Aggregation (POA).
Internet will deploy DSLAMs and DSL routers from
Cisco Systems and will have special status as a Cisco
Powered Network. Internet also equips our connection
points with Metallic Loop Test Devices, or MLTs.
Internet uses Turnstone's Copper Cross-Connect
system to provide this functionality. The twisted pair
from your location will be connected to an MLT port.
Via the MLT, Internet can proactively verify the
quality and capability of your copper connection prior
to installation, and at any time remotely test your
twisted-pair wiring to allow rapid troubleshooting and
resolution of wiring issues and network faults.
The POA is Internet's communication point within
a city. Our POAs are located in secure facilities with
24 X 7 physical access control, redundant power systems,
and redundant environmental systems to ensure the highest
possible level of reliability.
Our Cisco Systems ATM switches and core routers operate
within the POAs. These routers will provide very high
speed switching to ensure low latency transfer of your
data. In addition, our POAs will be pre-designed to
house application servers to enable value-added solutions
like multimedia, voice, data and video over a single
connection, to be provided in secure intranets and extranets
for our customers.
Service providers will interconnect with the request
DSL network at local POAs. This will enable these service
providers to offer DSL based broadband solutions
