Sharing Business Broadband
Even smaller businesses can have high performance dedicated Internet
access by splitting the cost of a T1 line with other businesses
in their building or business park.
Advantage of Colocation Bandwidth
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 T1, DS3, Carrier
Ethernet and SONET Fiber Optic options. These data centers also
offer backup power, environmental control and high levels of security.
What Are 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.
T1 Digital Cross Connect Systems
A digital cross connect system, often abbreviated DCS or DCAS,
allows you to switch traffic among your T1 lines. It will even
reach into the line to connect individual channels or timeslots
rather than the entire circuit. A manual device that cross connects
T1 lines is called a DCX or patch panel.
How do T1 and DS1 differ?
In general conversation, T1 and DS1 refer to the same thing. But
strictly speaking, T1 refers to a physical line circuit consisting
of 2 pair of copper wires with strict line signal specifications.
DS1 stands for Digital Signal level 1. DS1 is the service level
you get on a T1 line. However, DS1 also is part of the digital
signal hierarchy used in T3 lines and SONET fiber optic carriers.
