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
Advantage of Colocation Bandwidth
Colocation is locating your servers in a colocation facility,
also known as a carrier hotel. Advantages of this approach include
ready availability of low cost bandwidth including T1, DS3, Carrier
Ethernet and SONET Fiber Optic options. These data centers also
offer backup power, environmental control and high levels of security.
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 and T3 Lines for Wireless
A WISP or Wireless Internet Service Provider needs a way to connect
the Internet to the tower radios. T1 lines and bonded T1 lines
are widely used for this purpose, as well as cellular tower backhaul,
because of their almost universal availability. T3 lines offer
28x the bandwidth of T1 lines but are typically more available
in larger metropolitan areas.
T-Carriers Offer Digital Telephony
T-Carriers, which include both T1 and T3 lines, offer digital
telephone trunking with multiple phone calls on a single physical
circuit. T1 lines can support up to 24 simultaneous phone calls.
T3 lines have 28 times the bandwidth of T1 lines and can offer
up to 672 simultaneous phone calls for large enterprise or call
