Abstract
An interface between an ATM network and a local network includes a cell disassembler for disassembling ATM cells from the ATM network and transmitting a disassembled signal to the local network. A cell assembler assembles a signal from the local network into ATM cells and transmitting the ATM cells to the ATM network. A cell loss detector is provided for detecting a loss of a cell in a series of ATM cells from the ATM network. A signaling cell detector detects a call setup ATM cell from the ATM network. A coincidence gate produces an output when there is a coincidence between the detection of the cell loss and the detection of the call setup ATM cell. When the coincidence is detected, a busy tone is supplied to the cell assembler, where it is assembled into ATM cells and transmitted to the ATM network.
