Type of ISDN service
Two types of ISDN services (lines) are available: Basic Rate Interface (BRI) and Primary Rate Interface (PRI). Each line is made up of separate channels known as B and D channels which transmit information simultaneously.
• BRI is known as 2B+D because it consists of 2 B-channels and one D-channel.
• PRI is known as 23B+D because it consists of 23 B-channels and one D-channel.
