Why Share Business Broadband
Costs?
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
business.
WAN Bottlenecks Now Readily
Unclogged
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
Bandwidth
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.
How Does DS3 differ from T3?
The terms DS3 and T3 are often used interchangeably. Both refer
to a TDM (Time Division Multiplexing) digital telecom service
operating at 45 Mbps. Strictly speaking, DS3 is the digital signal
level that can be carried by either copper or fiber physical links.
T3 is the T-Carrier standard for DS3 over coaxial copper service.
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.
