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 for Call Center Telephony
DS3 voice service can support up to 672 simultaneous telephone
conversations without blocking. If your call center or large corporate
PBX system requires this number of outside lines, DS3 is likely
far more cost effective than ordering the equivalent 28 T1 lines.
DS3 as Ethernet Transport
DS3 bandwidth at 45 Mbps can easily transport 10 Mbps Ethernet
over SONET or T3 line, even with the additional overhead needed
to convert from packet to TDM back to packet protocol. For Fast
Ethernet transport, an OC3 service at 155 Mbps would be required.
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.
