Telecom Data Circuit T-1 (point-to-point service on campus)

DESCRIPTION

Data circuit T-1 (or DS-1) point-to-point service provides 1.5 Mbps bandwidth for data, voice, and video transport.  This service is provided by Telecommunications using Siemens PBX system(s).

FUNCTIONALITY LIST
Provides a mid level broadband connectivity for data, voice, and video services.  On campus, T-1s can be provided via UCF Telephone system.

TECHNICAL SPECIFICATIONS
Digital signal 1 (DS1, also known as T1, sometimes “DS-1”) is a T-carrier signaling scheme devised by Bell Labs. DS1 is a widely used standard in telecommunications in North America and Japan to transmit voice and data between devices. E1 is used in place of T1 outside of North America, Japan, and South Korea. Technically, DS1 is the logical bit pattern used over a physical T1 line; however, the terms “DS1” and “T1” are often used interchangeably. Also, the 24 channels of traffic in a T1 line are sometimes called a T-span.  A DS1 circuit is made up of twenty-four 8-bit channels (also known as timeslots or DS0s), each channel being a 64 Kbit/s DS0 multiplexed carrier circuit. A DS1 is also a full-duplex circuit, which means the circuit transmits and receives 1.544 Mbit/s concurrently. A total of 1.536 Mbit/s of bandwidth is achieved by sampling each of the twenty-four 8-bit DS0s 8000 times per second. This sampling is referred to as 8-kHz sampling (See pulse-code modulation). An additional 8 Kbit/s of overhead is obtained from the placement of one framing bit, for a total of 1.544 Mbit/s.
