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
Channelized and Unchannelized
A T1 line may be configured as a single large pipe offering 1.5
Mbps data transport or as 24 individual channels of 64 Kbps each,
ideal for use as individual outside telephone lines to support
Key or PBX business telephone systems.
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 Lines are Full Duplex
T1 lines are bidirectional or full duplex. That means that you
can independently upload and download data at up to the full line
rate of 1.5 Mbps simultaneously. LANs that use switched Ethernet
are also full duplex, but LANs that use hubs operate at half-duplex.
A half-duplex network cannot transmit and receive at the same
time, cutting effective bandwidth by up to half.
What is POTS mean?
POTS is a telecommunications industry acronym for "Plain
Old Telephone Service." POTS lines are the analog telephone
lines that have been trenched or dropped into nearly every business
and residence in the country. POTS service is based on standards
that have been well established for over a hundred years.
