PRI (Primary Rate Interface) is an ISDN connection designed to be provided over T1 lines. In the United States, a PRI line consists of 24 (64 kbps each) DS0 channels. PRI lines are commonly configured so that 23 channels serve as B (Bearer) channels and one as a D (delta) channel. Each B channel carries data, voice, and other services.

Written by: Dennis Green - Aug 21, 2008 OC3 circuits carry a bandwidth of 155.5 Mbps. OC3 (optical carrier) is the equivalent of three OC1s; each OC1 carries 51.85 Mbps. OC3 facilitates Voice over IP (VOIP), hosting web sites for very large companies, streaming audio and/or video, or video conferencing. OC3 carries enough bandwidth to supply most internet service providers. OC3 is often far more bandwidth than most companies need. For maximum efficiency and reduced cost, other options include: T1 (1.54 Mbps), fractional t1 (less than 1.54 Mbps), integrated T1 (combination of voice and data), bonded T1 (multiple T1 lines), burstable DS3 (T3), T3 (45 Mbps), or integrated T3 (DS3). Each of the services listed above has unique advantages. Which product is best suited for your company depends on your bandwidth applications and projected usage patterns. To check availability and/or pricing for any of the above mentioned service, please use the pricing tool at the top of this page. It’s easy to use, free, and without obligation.
