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
When to Use Pseudowires
A pseudowire is a virtual "circuit" that emulates a
traditional digital telecom service but on a packet switched network.
MPLS networks are especially suitable for pseudowires. By using
a pseudowire circuit, you can get the point to point connectivity
you desire without having to re-engineer your facilities to accommodate
a different protocol network.
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.
What is the T-Carrier System?
T-Carrier is a set of standards developed by the Bell Telephone
Companies back in the 1950s. These include T1 and T3 lines. They
also define digital signal levels such as DS0, DS1 and DS3. DS0
is 64 Kbps, DS1 is 1.5 Mbps and DS3 is 45 Mbps.
What is DS3 over Copper?
DS3oC, or DS3 over Copper, is a last mile connectivity solution
that delivers high bandwidth service where fiber optic connections
are unavailable or not cost effective to construct. Instead, standard
twisted pair copper wires like those used for telephone or T1
line service provide the link from the carrier POP to your building.
Multiple pairs and special modulation schemes are used to provision
carrier-grade DS3 service on copper wiring.
