Sharing Business Broadband Costs
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.

Channelized T1 vs ISDN PRI
T1 lines can support two protocols of switched circuit telephony. Channelized T1 lines offer 24 phone lines using in-band signaling. ISDN PRI, or Primary Rate Interface, offers 23 phone lines and common channel signaling that can include data such as ANI Automatic Number Identification or Caller ID.

T1 Lines are Full Duplex
T1 lines are bidirectional or full duplex. That means that you can independently upload and download data at up to the full line rate of 1.5 Mbps simultaneously. LANs that use switched Ethernet are also full duplex, but LANs that use hubs operate at half-duplex. A half-duplex network cannot transmit and receive at the same time, cutting effective bandwidth by up to half.

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.
