DS3 vs Multiple T1 Lines
Bonding T1 lines for greater bandwidth is a good value up to about
8x or 9x bonding. Above that, it makes better economic sense to
order DS3 service over fiber or T3 copper line. In metropolitan
areas with high levels of buildout, the decision point may be
less than 8 T1 lines.
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.
How DS3 Relates to OC3
DS3 is a digital signal level originally developed to support
the copper based T-Carrier digital telephone trunking system.
DS3 offers about 45 Mbps of bandwidth . OC3 is a SONET optical
carrier standard running at about 155 Mbps. An OC3 link can transport
up to 3 separate DS3 services.
What is Fractional DS3 Service?
Fractional DS3, as the name implies, is a fraction of the full
DS3 bandwidth of 45 Mbps. Companies order fractional DS3 when
they don't need or want to pay for the full bandwidth offered
by DS3. Even with fractional DS3, you still need the full coaxial
or optical hardware support for 45 Mbps signaling. At low fractional
requirements, bonded T1 lines offer a more cost effective solution.
