Nine months ago you had 8 awesome employees and business was good - correction: business was great because a fireball of potential clients were rising on the horizon. Your team performed supremely over the next couple of months and they signed several new clients that grew your business 200%. Whoa, now your team, who were operating efficiently before the growth, is over-extended. The time had arrived to bring on new talent to support your new clients; but that also meant the time had arrived to improve the technology in the office to support your team - ideally at a cost-effective price. The moment to install a T1 line had presented itself.
T1 line technology originally was developed in the 1950s by Bell Labs with local use being introduced in 1961. A traditional telephone line (also called POTS - plain old telephone service) is what most people are familiar with, but with the booming telecommunications industry and improved technology to run data circuits, T1 lines have become commonplace for small businesses.
T1 lines generally run on fiber optic technology focused on business internet service. Optical fibers have become prevalent among telecommunication, television and internet providers because they permit transmission over longer distances and at higher data rates over other technology such as copper wire. A T1 line can carry 24 digitized voice channels (64 Kbit/s per line) or a total of 1.544 Mbit/s for data. The T1 line will plug into the office's phone system for telephone conversations or if it's for transferring data the line will go into the network's router. Some providers will offer seamless voice and data communications with routing over a single circuit. Some businesses will opt for two T1 lines (Bonded T1) to allocate data on one line and telephone communication on the other as the more voice calls in use will decrease the total 1.554Mbit/s by -64Kbit/s per call in use.
For an in depth look at how the rate of 1.544Mbit/s was divided into channels, Wikipedia offers this explanation:
Given that the telephone system nominal voiceband [human hearing frequency] is 4,000 Hz, the required digital sampling rate is 8,000 Hz. Since each T1 frame contains 1 byte of voice data for each of the 24 channels, that system needs then 8,000 frames per second to maintain those 24 simultaneous voice channels. Because each frame of a T1 is 193 bits in length (24 channels × 8 bits per channel + 1 framing bit = 193 bits), 8,000 frames per second is multiplied by 193 bits to yield a transfer rate of 1.544 Mbit/s (8,000 × 193 = 1,544,000).
Fascinating information, indeed, and very cost effective as T1 lines run in the $400-600 range. As your business expands so too can the technology to support your operations. Bonding of T1 lines essentially has no limits although specific names are given at certain levels. A T2 line combines 4 T1 lines (6.312 Mbit/s) and a T3 line combines 28 T1 lines (44.736 Mbit/s). Whatever the need, the technology is there to propel your business into the future.
