Question

Quizplus · Accepted Answer

Basic rate interface (BRI) provides a communications circuit with two 64 Kbps B channels for voice and data, plus one D channel used for signaling and control. It is used for ISDN services and is typically offered to both residential and commercial customers. The upper capacity of BRI is 128 Kbps. Option A is incorrect as BRI is not offered only to commercial customers. Option C is incorrect as the definition of BRI may differ slightly in Europe. Option D is incorrect as the upper capacity of BRI is 128 Kbps, not 1.544 Mbps. Option E is incorrect as BRI is a digital circuit, not analog.
