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.
How DS3 Relates to OC3

the copper based T-Carrier digital telephone trunking system.
DS3 offers about 45 Mbps of bandwidth . OC3 is a SONET optical
carrier standard running at about 155 Mbps. An OC3 link can transport
up to 3 separate DS3 services.
