Our Dynamic T1 combines high-speed Internet access with feature-rich telephone functionality, providing unrivaled flexibility. Unlike Integrated T1s that reserve a certain number of channels for voice, with the remainder being used for data, Dynamic PRI voice channels don't have to be reserved, so the bandwidth on any idle phone lines is available for data. When a phone is active, the service automatically prioritizes bandwidth, while ensuring Quality of Service (QoS) for your calls. Whether you need a single T1, bonded T1s or a full DS3, O1 Dynamic Business Services will work for you!

How does a T1 line work?

Most of us are familiar with a normal business lines from a phone company. A normal phone line is delivered on a pair of copper wires that transmit voice as an analog signal. When you use a normal modem on a line like this, it can transmit data at perhaps 30 kilobits per second (30,000 bits per second).

A T1 line can carry 24 digitized voice channels, or it can carry data at a rate of 1.544 megabits per second. If the T1 line is being used for telephone conversations, it can plug into the office's phone system. If it is carrying data it plugs into the network's router. At O1, we offer both types of lines. Our T1 line that carries both data and voice, known as O1's Dynamic T-1. A T1 line can carry about 192,000 bytes per second -- roughly 60 times more data than a normal modem. It is also extremely reliable; much more reliable than an analog modem. We offer Dynamic Voice and Data solutions.

Often, large companies may need more than a T1 line. Here are some of the common line designations:

* DS0 - 64 kilobits per second
* ISDN - Two DS0 lines plus signaling (16 kilobytes per second), or 128 kilobits per second
* T1 - 1.544 megabits per second (24 DS0 lines)
* T3 - 43.232 megabits per second (28 T1s)
* OC3 - 155 megabits per second (84 T1s)
