Digital system 1 or digital signal level 1. Term used to refer to the 1.44 Mbps digital signal carried on a T1 facility. (See also T1)
Digital signal, level 1; 1.544 megabits per second, the North American standard
Digital Service, level 1. Consists of 1.544 Mbps in North America and 2.048 Mbps elsewhere. Also called T-1. Equivalent to twenty-four DS-0 channels.
The digital transmission facility operating with a nominal bandwidth of 1.544 Mbps; it is the primary digital communications system in North America.
(Facility) T1- The equivalent of 24 multiplexed voice grade channels ( DS-0 s). 1.544 million bits per second (1.5Mbps)
A framing specification used in transmitting digital signals at 1.544 Mbps over a T-1 facility (U.S.) or at 2.108 Mbps over an E-1 (Europe).
Digital Service Level 1, a 1.544Mbps channel supported by T1 service. 24 DS-0 channels make up one DS-1 channel.
Digital signal level 1. A standard term describing the 1.544 Mbps digital signal carried on a T-1 facility or the 2.048 Mbps digital signal carried on an E-1 facility. A DS-1 line is made up of 24 time division multiplexed DS-0 channels. T-1 and E-1 signals are primarily transmitted over DS-1 lines composed of standard twisted-pair copper wire. One twisted-pair is used for the transmit signal and a second twisted-pair is used for the receive signal creating a full duplex circuit. In order to offer additional features, a DS-1 line can be administered with IDSN protocols. (source)
T-1 transmission rate of 1.54 million bits per second - 24 channels of 64 kpbs.
Type of line] A line capable of delivering 1.54 Mbps (1,540 Kbps) in both directions.
Digital service level-1, a 1.544 Mbps channel in North America or a 2.048 Mbps channel in CCITT countries. Typically composed of multiple DS-0 channels. Typically a DS-1 is composed of 24 DS-0 signals.
The equivalent of 24 multiplexed DS-0 voice grade channels (1.5 Mbps).
The equivalent of 24 DS-0's. Otherwise known as a T-1 line. Approximately 1.544 Mbps of bandwidth.
Digital circuit with standardized operating characteristics and transmitting capacity equivalent to 24 voice-grade (64 Kbps) circuits (1.544 Mbps) Circuits are used to carry moderate volumes of traffic by both end users and carriers.
