Why Share Business Broadband
Even smaller businesses can have high performance dedicated Internet
access by splitting the cost of a T1, T3 or fiber optic line with
other businesses in their building or business park. By pooling
resources, the group can afford a higher bandwidth than any individual
WAN Bottlenecks Now Readily
Your Wide Area Network or WAN may be the bottleneck in your network
when you have significant voice or data transfer between facilities.
With lower line prices available, unclogging the WAN can cost
less than you think and can unleash higher business productivity.
DS3, OCx over SONET and Carrier Ethernet connections are recommended
for the corporate WAN.
Applications Demanding DS3
DS3 transport is often used for real time video transport, high
resolution images, large engineering files, and data backups to
remote data centers. You can get this bandwidth through fiber
optic delivery or over copper coaxial lines, called T3 lines.
What is the T-Carrier System?
T-Carrier is a set of standards developed by the Bell Telephone
Companies back in the 1950s. These include T1 and T3 lines. They
also define digital signal levels such as DS0, DS1 and DS3. DS0
is 64 Kbps, DS1 is 1.5 Mbps and DS3 is 45 Mbps.
The Importance of DS0
DS0 and DS3 are part of the same set of digital signal standards.
DS0 is 64 Kbps, the bandwidth required to support one telephone
call of 8 bits at a sampling rate of 8 Kbps. DS3 has a speed
of 44,736 Kbps, commonly referred to as 45 Mbps. This speed level
was chosen so that 672 DS0s could be multiplexed into one DS3.
One DS3 can also multiplex 28 DS1 services. DS1 is the signal
level transmitted on a T1 line.
