DS3 Equivalent to 28 T1 Lines
DS3 service at a signaling rate of 44.736 Mbps is the equivalent
of 28 T1 lines at their signaling rate of 1.544 Mbps. Because
of the strict synchronization of TDM services, 28 T1 lines may
be multiplexed into a single DS3 service.
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 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.
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.
