Abstract
A method for dynamically varying bandwidth of a primary rate ISDN interface includes requesting, over a data (D) channel, allocation of at least one first B channel of the primary rate ISDN interface. When notification of allocation of the first B channel is received, over the D channel, data is sent over the first B channel. A relationship is monitored between a first bandwidth demand parameter and first and second threshold values. If a predetermined relationship exists between the first bandwidth demand parameter and the first threshold value, allocation of at least one second B channel of the primary rate ISDN interface is requested. In response to receiving notification of allocation of the second channel, data is sent over the second B channel. The second B channel is released in response to a relationship between the first bandwidth demand parameter and a second threshold. A hyper primary rate ISDN interface (HPRI) defines a virtual primary rate interface (PRI) that does not include a predetermined number of B channels. A bandwidth user can statically request any number of the available bearer channels. Alternatively, B channels can be dynamically allocated or de-allocated based on demand.
