These are adapted to specific traffic load situations with a defined maximum number of communication channels Basic Rate Access BRA A basic rate access is used for a low traffic load It normally includes one signalling channel D and two communication channels B An example of a subscriber connected via basic rate access is a private home or a small business The BRA uses the common 2 wire subscriber line Primary Rate Access PRA A primary rate access can handle a higher traffic load than the basic rate access ISPBX and IMUX are two example of devices which can be connected to a PRA Bit Rates The B channels have a bit rate of 64 kbits sec whereas there are two bit rates implemented for the D channel When the D channel used as a signalling channel for a basic rate access 16 kbits sec is enough to handle the signalling information for the two B channels and a limited amount of user to user information primary rate access can contain up to 30 B channels and consequently requires a higher capacity for signalling The D channel for a primary rate access has a bit rate of 64 kbit s Both D and B channels are full duplex channels 13 SYSTEM OVERVIEW The implementation of ISDN feature in the 256P ANRAX will provide the concentration for maximum 15 ISDN subscribers through V5 2 Interface The system supports only BRI interface provisioning thus devices like ISPBX and IMUX cannot be connected to the ANRAX which
