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.
DS3 as an Internet Backbone
DS3 service configured as an dedicated Internet port offers 45
Mbps of upload and download bandwidth. This is ideal for small
and medium size ISPs and WISPs. that have exceeded the capacity
available from multiple T1 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.
Difference Between DSL and
DSL means Digital Subscriber Line and is a shared bandwidth service
offered on a "best effort" basis by telephone companies.
DS3 is a professional telecom service with a fixed bandwidth of
45 Mbps both upload and download. DS3 is usually sold with on
a contract with a service level agreement.
