DS1 lines are carried through two twisted pairs of copper wires. Virtually, all residences and businesses currently have two pairs of copper wires running to them. DS1 lines are capable of delivering 1.54 Mbps simultaneously in both directions, one direction for each pair of copper lines. Because DS1 service is repeater driven (signal is digitally reestablished about every 6000 feet), it is available several miles from telephone central offices. For this reason, DS1 can be available to virtually all businesses in the US. DS1 lines are dedicated, in that they are always connected, and are also extremely stable. Most reputable providers include service level agreements which guarantee the reliability of the DS1s they offer. Although, each DS1 circuit has traditionally been capable of providing a maximum 24 phone lines, due to advancement in coding techniques, some are now capable of supplying up to 36 phone lines. There are several types of DS1. These include: full DS1 (1.54 Mbps), fractional (commonly 128 Kbps to 756 Kbps), burstable (less expensive for companies which normally do not need a full DS1, but at times due to peak work loads, need to burst to full DS1 bandwidth), integrated (one DS1 line comprised of any combination the types of DS1 listed here), channelized DS1 (a type of integrated DS1), point-to-point (direct and constant DS1 connection between to locations), data (internet), voice (telephone), local (local phone service), pri (voice service which includes many added features such as caller ID), and frame relay (bandwidth from a shared network). Each of these types of DS1 has advantages over the others, depending on the specific needs of your company. Also, the availability of each is based on the offerings of each DS1 provider and the geographic location.

 Integrated T1 Now Includes Unlimited Free Long Distance Service

Written by: Dennis Green - Nov 20, 2008


Too good to be true? Not any more. Some major integrated T1 telecom providers are now including unlimited free long distance service with their integrated T1 plans. With one integrated T1 circuit, your company can now actually have up to 16 voice lines, dynamic bandwidth allocation (full T1 bandwidth when voice lines are not in use), free unlimited local and long distance service to anywhere in the domestic US (even from metered locations), and up to 5000 minutes of free toll free service per month. All of this is provided for about the same cost, or slightly more than the average data (internet) T1 line. It should be noted that to prevent abuse, all providers which offer unlimited long distance actually place a cap on LD usage. Some, place that cap at 50,000 minutes per month, others at 100,000 minutes per month. If the cap is exceeded, then per minute charges apply to usage over the cap. Also, free unlimited LD plans are not provided to call centers or companies which utilize auto dialers. However, for virtually all small to medium sized companies, which are not call centers, 50,000 minutes of month is usually the equivalent of “unlimited”. Most small to medium sized companies never exceed 20,000 to 30,000 minutes of LD usage in a given month. For large companies, and companies which utilize call centers or auto dialers, there are excellent plans available that will provide unlimited long distance (with no cap) for less than a penny a minute, and unlimited toll free service for about 1.2 cents per minute.
