Combined T1 Telephone and Internet
Service
An Integrated T1 line shares bandwidth between digital phone lines
and broadband Internet service. Typically up to 12 phones lines
can be accommodated. If the T1 line is set up to be a dynamic
T1, then any bandwidth not used for telephone calls is automatically
available for Internet access.
Bonding T1 Lines for Higher
Bandwidth
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
are recommended.
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.
