T1 vs DSL for Business Broadband
T1 lines set up as T1 Dedicated Internet connections give business
users guaranteed bandwidth of 1.5 Mbps both upload and download,
plus a SLA service level agreement to assure line reliability.
DSL is a "best effort" Internet service that is offered
without any service guarantee on a shared connection. Bandwidth
varies depending on how heavily other businesses are using the
Bonding T1 Lines for Higher
While a standard T1 line provides 1.5 Mbps upload and download
bandwidth, lines can be bonded to create total bandwidths of 3
Mbps, 4.5 Mbps, 6 Mbps, 7.5 Mbps, 9 Mbps, 10.5 Mbps and 12 Mbps.
An advantage T1 lines have over fiber optic connections is that
they are available nearly everywhere without special construction.
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 might easily suffice. For medium
and larger facilities, T3 lines and fiber optic carrier services
T1 Digital Cross Connect Systems
A digital cross connect system, often abbreviated DCS or DCAS,
allows you to switch traffic among your T1 lines. It will even
reach into the line to connect individual channels or timeslots
rather than the entire circuit. A manual device that cross connects
T1 lines is called a DCX or patch panel.
How do T1 and DS1 differ?
In general conversation, T1 and DS1 refer to the same thing. But
strictly speaking, T1 refers to a physical line circuit consisting
of 2 pair of copper wires with strict line signal specifications.
DS1 stands for Digital Signal level 1. DS1 is the service level
you get on a T1 line. However, DS1 also is part of the digital
signal hierarchy used in T3 lines and SONET fiber optic carriers.
