T1 Vs T3 Line Speed

T1 vs T3 Lines

The digital capacity of a plain old telephone service (POTS) line is 64 Kbs. There are 8000 timing bits added, so the actual throughput is 56 Kbps. This is enough to carry a single voice call or to connect a 56 Kbs modem. The POTS line is an analog line; it transmits and receives analog or sound-based signals.

T1 Lines

A T1 line is a purely digital line. Conversations are converted (at a PBX) from analog (sound) to digital before being transmitted on the T1 line.

The T1 line can handle 24 simultaneous voice calls. (24 simultaneous voice calls can satisfy anywhere from 24 to well over 100 office workers, depending on their calling patterns.)

Sometimes one of the 24 lines is dedicated to caller ID; this line is usually connected to a computer that looks up customer records that are routed to the computer of the person taking the call.

A T1 line can handle a high speed Internet connection speed of 1.544 Mbps.

Or, as an "integrated data and voice" service it can handle a combination of fewer voice calls with some bandwidth given to Internet connections.

T3 Lines

A T3 line is also a purely digital line. It is the equivalent of 28 T1 lines or 672 POTS lines.

A T3 line can handle 672 simultaneous voice calls or provide a high speed Internet connection of 44.736 Mbps. As an integrated service, it can handle a combination of fewer voice calls and provide high speed Internet connections. The T3 is typically used by high end data and voice customers.

Monthly Costs

Monthly costs for T1 and T3 lines vary, primarily depending on the distance from your local phone company's Customer Office (CO). As a very rough comparison we can say a T1 might cost $500 per month while a T3 might cost $4,000 per month.

Understanding T1

If your business has more than 8 phone lines or more than $750 in telecom billing you should consider a T1 line.

A digital T1 line is equivalent to 24 normal external (analog) phone lines. Your business can

  • Make 24 simultaneous external calls (Voice/FAX only),
  • Have high speed Internet (Data only), or
  • Have a combination of phone lines and Internet (Integrated voice and data).

Note that the capability to make 24 simultaneous external calls can satisfy the needs of 24 to several hundred individual phone users, depending on their call volume.

A T1 line is a dedicated line (local loop) between your location and, normally, the phone company's Customer Office (CO). Pricing depends primarily on the length of this local loop--that is, the distance between your location and the Customer Office.

T1 lines are highly reliable. Phone companies provide a service level agreement that provides for fast restoration in case of severe weather or other outages.
