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
Colocation is Often Cost Effective
Colocation is locating your servers in a colocation facility,
also known as a carrier hotel. Advantages of this approach include
ready availability of low cost bandwidth including DS3, Carrier
Ethernet and SONET Fiber Optic OCx options. These data centers
also offer backup power, environmental control and high levels
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.
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.
