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.
DS3 as an Internet Backbone
DS3 service configured as an dedicated Internet port offers 45
Mbps of upload and download bandwidth. This is ideal for small
and medium size ISPs and WISPs. that have exceeded the capacity
available from multiple T1 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.
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.
