T1 vs DSL for Business Broadband
T1 lines set up as T1 Dedicated Internet connections give business users guaranteed bandwidth of 1.5 Mbps both upload and download, plus a SLA service level agreement to assure line reliability. DSL is a "best effort" Internet service that is offered without any service guarantee on a shared connection. Bandwidth varies depending on how heavily other businesses are using the connection.

Bonding T1 Lines for Higher Bandwidth
While a standard T1 line provides 1.5 Mbps upload and download bandwidth, lines can be bonded to create total bandwidths of 3 Mbps, 4.5 Mbps, 6 Mbps, 7.5 Mbps, 9 Mbps, 10.5 Mbps and 12 Mbps. An advantage T1 lines have over fiber optic connections is that they are available nearly everywhere without special construction.

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.

Fractional T1 Service as a Money Saver
Not all businesses need the full 1.5 Mbps of a T1 line, but want higher availability and the dedicated bandwidth offered by T-carrier digital service. In many cases, fractional T1 services offers a fraction of the bandwidth at a lowered monthly lease price. Fractional T3 service may also be available for bandwidth needs between 1.5 and 45 Mbps.

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.
