Abstract:
A method of regenerating a point-to-multipoint interface on a point-to-point interface in an ATM (Asynchronous Transfer Mode) network configuration, the method comprising:a) using a circuit means with the point-to-multipoint interface and the point-to-point interface, for transmission of data to/from a plurality of circuits on said point-to-point interface, b) using said circuit means to identify from which circuit an ATM cell originated, by using pre-pending byte(s) and/or user defined byte(s) in the respective ATM cell, c) assigning individual PID tags (Physical Interface Identification tags) to said byte(s), d) providing intermediate storage means in said point-to-point interface; e) causing said circuit means to read data from said point-to-point interface, at least one of the physical interface identification tags (PID tags) being decoded corresponding to a point-to-multipoint address (PMP_ADDR), said PID tag being stored in logic means, while storing said ATM cell, f) using said logic means to identify which PID tag corresponds to which ATM cell being stored, and g) causing said circuit means to respond to polling from the point-to-multipoint interface of a port following said circuit means by responding to the point-to-multipoint address which corresponds to the PID tag of the next ATM cell in storage.
