Abstract
A modular expandable telecommunication system having a main cabinet and at least one expansion cabinet that are interconnected with each other to obtain an extended telecommunication system with increased connection possibilities for extensions and trunks. The main cabinet and each expansion cabinet have a transmission interface unit allowing connection of the expansion cabinet(s) to the main cabinet via a single transmission link conveying voice/data channels and low level signaling for mutual synchronization and clock recovery for all interconnected cabinets. The main cabinet has a master clock device, a CPU for running software applications and a DSP for routing the higher level messages issued by the CPU depending on the physical location of the expansion cabinet.
