T1 Voice and Data Quotes

T1 refers to the primary digital telephone carrier system used in North America. T1 is one line type of the PCM T-carrier hierarchy listed in the table below. T1 describes the cabling, signal type, and signal regeneration requirements of the carrier system.

T1 was first installed in the early 1960s and was used only to carry voice trunks between central offices. Since then, T1 line facilities have been provided by telephone companies to customers who need many outside lines. Since a T1 line supports up to 24 simultaneous voice and / or data calls, a large savings in both cable and service cost can be realized by replacing many individual local loops with a single T1 link to the Central Office. In addition to telephone-company provided T1 services, many private T1 networks have been implemented such as LAN gate-ways and PBX-to-PBX links.
