What is DS3?
DS3 or Digital Signal level 3 is a standardized TDM service offering
a bandwidth of 45 Mbps. It may be delivered over SONET fiber optic
service or over copper coaxial cable. When delivered over copper,
the line is generally referred to as a T3 line.
WAN Bottlenecks Now Readily
Your Wide Area Network or WAN may be the bottleneck in your network
when you have significant voice or data transfer between facilities.
With lower line prices available, unclogging the WAN can cost
less than you think and can unleash higher business productivity.
DS3, OCx over SONET and Carrier Ethernet connections are recommended
for the corporate WAN.
Applications Demanding DS3
DS3 transport is often used for real time video transport, high
resolution images, large engineering files, and data backups to
remote data centers. You can get this bandwidth through fiber
optic delivery or over copper coaxial lines, called T3 lines.
DS3 as Ethernet Transport
DS3 bandwidth at 45 Mbps can easily transport 10 Mbps Ethernet
over SONET or T3 line, even with the additional overhead needed
to convert from packet to TDM back to packet protocol. For Fast
Ethernet transport, an OC3 service at 155 Mbps would be required.
What is DS3 over Copper?
DS3oC, or DS3 over Copper, is a last mile connectivity solution
that delivers high bandwidth service where fiber optic connections
are unavailable or not cost effective to construct. Instead, standard
twisted pair copper wires like those used for telephone or T1
line service provide the link from the carrier POP to your building.
Multiple pairs and special modulation schemes are used to provision
carrier-grade DS3 service on copper wiring.
