Abstract: The present invention concerns a modular expandable telecommunication system, such as a private automatic branch exchange system (PABX), comprising a main cabinet and at least one expansion cabinet, which are interconnected with each other in order to obtain an extended telecommunication system with increased connection possibilities for extensions and trunks. System characterized in that the main cabinet and each of the expansion cabinet comprise a transmission interface unit allowing connection of the said expansion cabinet(s) with said main cabinet via a single transmission link conveying voice/data channels and low level or local signaling for performing at least mutual synchronization and clock recovery for all interconnected cabinets, the main cabinet comprising in particular a master clock device, a CPU for running the application and a DSP for routing the higher level messages issued by the CPU depending on the physical location of the destination cabinet.

Abstract: The present invention concerns a method for treating or handling, at the receiving side, packets of data transmitted with variable delays through a network using Internet Protocol. A method is disclosed, where one calculates repetitively an acceptable delay range from an average value of several delays determined for several packets at their arrival time and by applying Gaussian law properties to said average value, and accepts only packets of data which are received with a delay within said range.

Abstract: Detection by a PBX of an incoming call started by a modem The basic idea of the present invention consists of taking advantage of the compatibility of almost every modem to a specific protocol called AT or Hayes commands. According to the present invention, the AT-commands will be used to generate a code specifying that the far end telecommunications device which just dialed is a modem. Therefore, when the dialed telecommunications device is connected to a PBX, latter will have to recognize said code after which it will transfer automatically that call to this telecommunications device identified by the dialed extension phone number and being a modem. Then a telecommunications connection between both modem will be set up. Advantageously, it is then possible by using present invention to connect several different telecommunications devices on a PBX, all being identified by the same extension phone number like a telephone, a FAX and a modem. A PBX according to the present invention will be able to redirect automatically a call coming from a modem to a modem.
