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.
Medical Imaging Transmission
Bandwidth
Medical images, such as those generated by Teleradiology equipment,
have large file sizes due to high resolution. Rapid transmission
between hospitals and medical centers requires high availability,
high bandwidth telecommunication services. For smaller offices
or infrequent use, a T1 data line or bonded T1 lines might suffice.
For medium and larger facilities, DS3, Fast Ethernet and OCx fiber
optic services are recommended.
Applications Demanding DS3
Bandwidth
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.
What is the T-Carrier System?
T-Carrier is a set of standards developed by the Bell Telephone
Companies back in the 1950s. These include T1 and T3 lines. They
also define digital signal levels such as DS0, DS1 and DS3. DS0
is 64 Kbps, DS1 is 1.5 Mbps and DS3 is 45 Mbps.
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.
