One of two levels of ISDN service. The BRI provides two bearer channels for voice and data and one channel for signaling (commonly expressed as 2B+D). See also Primary Rate Interface (PRI).
This is an ISDN interface that has two B (bearer) channels that carry voice or data and one 16 Kbps D (data) channel. Also called Basic Rate Access (BRA).
The ISDN standard governing how a customer's desktop terminals and telephones can be connected to an ISDN switch. The BRA is an ISDN standardised access offering two B Channels (64 kbits) for voice or data transmission and one D Channel for Signaling (16 kbits/s) according to the ITU-T Standard Rec. I.430.
An ISDN line providing 2 B = D (two "bearer" channels and one "data" signaling channel) service.
ISDN offering that allows 2 64kbps and 1 16kbps channels to be carried over 1 typical single pair of copper wires. This is the type of service that would be used to connect a small branch or home office to a remote network. Through the use of BONDING (Bandwidth on Demand) the two 64kbps channels can be combined to create more bandwidth as it becomes necessary.
BRI provides 2B + D, which is two bearer B-channels at 64 kilobits per second and one data D-channel at 16 kilobits per second. The bearer channels are designed for voice, video conferencing, faxes etc. The D- channel is for bringing in information about incoming calls and for taking out information for outgoing calls. One BRI standard is the "U" interface that uses two wires. Another BRI standard is the "T" interface that uses four wires.
An access interface that most small businesses and individuals use for ISDN. For this service, the telephone company divides the connection between you and the central office into three separate channels, two 64 Kbps B (bearer) data channels and one 16 Kbps D control channel. This service is called 2B+D.
Edit / BRI - This is the typical (basic) ISDN configuration. It consists of 2 'B' channels which can each carry digitized audio or data at a rate of 64 Kbit/s and one 'D' channel opperating at 16 Kbit/s for carrying data and signaling. This configuration is sometimes reffered to as 2B+D (two 'B' channels and a 'D' channel). See Also: ISDN
An ISDN BRI is a basic ISDN telephone connection commonly used for small office, home, and ISDN voice telephone service. Each ISDN BRI has two 56 or 64Kbps B Channels and one 16Kbps D Channel.
2 Bearer (B) channels of 64k each plus one Data Link (D) channel of 16k
On an ISDN line, the smaller line which consists of two "B" channels (64 kbps each). With the appropriate phone company service package and correct terminal adapter, it is possible to talk on one B channel while transmitting data on the second B channel.
An ISDN access or subscriber line, consisting of two 64Kbps B ("bearer") channels and one 16Kbps D channel used for both data and signaling purposes.
An ISDN subscriber line, consisting of two 64 kbit/s B channels, or "bearer" channels, and one 16 kbit/s D channel, used for both data and signaling purposes.
BRI) See ISDN. Beam splitter For tele- oto/ophthalmoscopes. Allows direct visualization through the device into the eye or ear by the clinician, while still routing a portion of the image to the video camera. This is usually preferred by the clinician who is accustomed to looking directly through the device rather than at a video monitor.
Standard ISDN line comprised of 2 B-channels and 1 D-channel.
A BRI line is one of two access methods for ISDN (the other one is Primary Rate Interface - PRI). A BRI has two 64 Kbps B channels and one 16 Kbps D channel.
In ISDN, an interface that provides two 64 000 bps data channels (B-channels) and one 16 000 bps signaling channel (D-channel). Also known as 2B + D. Contrast with primary rate interface (PRI).
The simplest form of network access available on (BRI) the ISDN (integrated services digital network). The BRI comprises 2B + D channels for carriage of signaling and user information.
The Integrated Services Digital Network basic rate interface consists of two 64-Kbps data or voice channels, which are designated as B (bearer) channels. The interface also has a 16-Kbps signalling or packet-data channel designated as the D (delta) channel. The interface is, therefore, often referred to as 2B+D
An ISDN line that provides up to two 64 Kbps B-channels and one 16 Kbps D-channel over an ordinary two-wire telephone line. B-channels carry circuit-oriented data or voice traffic while D-channels carry call-control signals.
Basic rate interface (BRI, 2B+D, 2B1D) is an Integrated Services Digital Network configuration defined in the physical layer standard I.430 produced by the ITU. This configuration consists of two 64 kbit/s "bearer" channels (B channels) and one 16 kbit/s "data" channel (D channel). The B channels are used for voice or user data, and the D channel is used for any combination of: data, control/signalling and X.25 packet networking.
