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
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.
Dedicated DS3 Internet Access
Business broadband via DS3 dedicated Internet service offers 45
Mbps of upload and download capability. That's enough to support
a medium size or larger office, including file transfers, email
and Web browsing, video conferencing and real-time ecommerce activities.
How Does DS3 differ from T3?
The terms DS3 and T3 are often used interchangeably. Both refer
to a TDM (Time Division Multiplexing) digital telecom service
operating at 45 Mbps. Strictly speaking, DS3 is the digital signal
level that can be carried by either copper or fiber physical links.
T3 is the T-Carrier standard for DS3 over coaxial copper service.
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.
