Abstract
A subscriber card includes a controller for concentrating Internet frames so as not to occupy a telephone circuit for each call to an Internet service provider. The subscriber card is connected to a switching matrix that facilitates transmission of the concentrated Internet frames to a data transmission network. The subscriber card handles multiple subscriber inputs and statistically multiplexes data from the multiple subscriber inputs in order to increase throughput.
Claims11
A digital subscriber card for a telecommunication network, the digital subscriber card comprising:
- a first means for concentrating Internet frames from a plurality of digital subscriber lines on n×64 kbit/s data links prior to transmitting the concentrated Internet frames through a virtual circuit to a data switch, and
- a second means for receiving an instruction supplied by a call processor to concentrate the Internet frames received from the plurality of digital subscriber lines and for controlling the first means concentrating and transmitting the Internet frames through the virtual circuit to the data switch,
- wherein the first means concentrates Internet frames received from a plurality of digital subscriber lines according to a predetermined frame relay protocol and stores the concentrated Internet frames into a queue, and the first means reads the concentrated Internet frames from the queue with circular priority.
