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 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.
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.
