What is a PRI?
A PRI (Primary Rate Interface) is a telecommunication standard used in the Integrated Services Digital Network or ISDN, for carrying multiple DS0 voice and data transmissions between two physical locations. PRI was developed specifically for industrial or large quantity users. PRI is an industrial ISDN line while the Basic Rate Interface, or BRI, is used to cater to home and small enterprises. Both Primary Rate Interface and Basic Rate Interface are made up of a number of B channels and D channels. B Channel or the Bearer Channel is used for data transmission, including voice, and D channel is meant for signaling and control. A PRI is made up of 23 B-channels and one 64 Kbps D-channel in a T-1 configuration and 30 B-channels and 1 D-channel using an E1 line. The T-carrier system is standard in Japan, US and Canada, while E1 is popular across Europe and Australia. In other words, in North America and Japan PRI is represented as 23B+D with a total bit rate of 1.544 Mbit/s (T1) while it is 30B+D in Australia and Europe, which is equivalent to a bit rate of 2.048 Mbit/s (E1). The Primary Rate Interface makes use of the Q.931 protocol over the D channel. A PRI is typically used to establish communication between a PBX, or a private branch exchange, which is a telephone exchange operated by the customer of a telephone company, and a Central Office of the telephone company or an Inter Exchange Carrier or IXC, a long distance telephone company. The advantage of primary rate interface or PRI is that the 23 or 30 B channels can be used in various combinations for specific data transmission needs, such as a videoconferencing, allowing bulk data transfer to be achieved more flexibly.

Bit Rate Interface?
Bit rate interface is another name for basic rate interface, or BRI. BRI is used in ISDN configurations for voice-grade telephone operations.
The speed of BRI ISDN interface is?
Maximum speed supported by ISDN BRI is 128 Kbps
What is BRI?
It stands for Basic Rate Interface. In the Integrated Services Digital Network (ISDN), there are two levels of service: the Basic Rate Interface (BRI), intended for the home and small enterprise, and the Primary Rate Interface (PRI), for larger users.
What is the maximum data rate for ISDN BRI?
ISDN BRI is a Basic Rate Interface for ISDN networks (Intergrated Services Device Network). It consists of 2 Channels: B+D. B channel is used for data and voice and consists of two 64Kbps channels=128Kbps. D channel is used for the signal and control of the interface and is 16Kbps. Together the B+D chanels are refered to as 2B+D. The maximum data rate on a BRI is therefore 128Kbps. NOTE:PRI is Primary rate Interface which uses 23x64Kbps B channel and 1x64Kbps D channel (T-1)
