Abstract (en)

[origin: WO9857503A2] A telecommunications exchange comprises a switching device (1201) of a first type through which telecommunications connections are routed. An access unit (1202) connects the switching device to a telecommunications network. The telecommunications exchange includes an exchange main processor (1200) which generates switch control messages for a switching device of a second type but which translates the switch control messages for use by the switching device of the first type. Preferably, the switching device of the second type is a group switch, and the exchange main processor is an open platform processor. The exchange main processor emulates portions of a telecommunications exchange which control the switching device of the first type, the emulated portions including a central processor (1234), regional processors, and a switching subsystem (1230). In emulating the central processor, the exchange main processor advantageously enables utilization of previously developed logic for telecommunications exchanges using the second switching device by translating coded instructions executable by the central processor into instructions executable by exchange main processor.
