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.

System and method for dynamically varying integrated services digital network (isdn) interface bandwidth

A residential access node (RAN) running a RAN platformwhich includes means for interfacing a plurality of peripheral equipment such as analog (POTS) phones, standard televisions, computers, IP telephones, and high definition televisionsto a packet data network. The Network Access Provider RAN platformmanages sessions among Customer Premises RAN platformsand Application Service Provider RAN platformsover high bandwidth connections. The Customer Premises RAN platformalso determines the number and type of data packets entering or departing via the packet data network. Such an architecture allows for the efficient transfer of services (data content) from Application Service Providers to individual network access subscribers by seamlessly accommodating various data types and providing an integrated metering and billing mechanism managed by the Network Access Provider.
