Abstract:
A method for switching traffic in a telecommunications node, comprising:communicating traffic over a time division multiplex (TDM) bus in a first frame structure repeating at a defined rate; operating a time slot interchanger (TSI) at a frame pulse matching the defined rate to switch traffic from the TDM bus to a shared memory and from the shared memory to the TDM bus based on predefined switching instructions; communicating traffic over an asynchronous transfer mode (ATM) bus within a second frame structure repeating at the defined rate; operating a bus fuser at the frame pulse to receive traffic from each one of the shared memory, the ATM bus, and an ATM switch and to route the traffic to another one of the shared memory, the ATM bus and the ATM switch; and operating the ATM switch at the frame pulse to switch traffic received from the bus fuser based on header information in the traffic.
