17. A method of a communication system synchronization by receiving and transferring data of information group, the communication system comprising a telecommunication apparatus for receiving and transferring data of information group connected to PSTN and comprising a recovery block separating receiving data of information group and recovery synchronization clock, one or more computer modules, one or more terminal devices connected to one or more analog FAXes and/or analog phones;
-
said method comprising following steps during the process of receiving-data of information group from PSTN; receiving of data information group from PSTN, separating said data to two signal groups—
data of information group and recovery synchronization clock,transmitting said signal groups from said recovery block via separate paths, correspondently;
said recovery synchronization clock to said terminal devices directly and said data of information group to said computer module via a high-speed interface,transmitting said data of information group further from said computer module to said terminal devices via said high-speed interface, creating outgoing data based on the said information group and transmitting said outgoing data via said terminal devices by using said recovery synchronization clock to said analog FAXes and/or analog phones; said method comprising following steps during the process of transmitting data from said analog FAXes and/or analog phones to said PSTN; receiving data from said analog FAXes and/or analog phones based on the said recovery synchronization clock, transmitting said data from said terminal device to said computer module via high-speed interface, data processing, transmitting said data from said computer module to said telecommunication apparatus via high-speed interface, creating transmitting data for PSTN based on the recovery synchronization clock and transmitting said data to PSTN. - View Dependent Claims (18)
said method wherein following steps of the process of receiving data of information group from PSTN: -
transmitting said signal groups from said recovery block via separate ways, correspondently;
said recovery synchronization clock to said terminal devices directly and said data of information group to said computer module via a high-speed interface,creating outgoing data based on the said information group and transmitting said outgoing data via said terminal devices by using said recovery synchronization clock to said analog FAXes and/or analog phones; and
following steps the process of transmitting data from said analog FAXes and/or analog phones to said PSTN; transmitting said data from said terminal device to said computer module via high-speed interface, creating transmitting data for PSTN based on the recovery synchronization clock and transmitting said data to PSTN; comprise intermediate step; buffering data with the help of said FIFO memory blocks for synchronization of moving said data between said asynchronous high-speed interface bus and synchronization ways (PSTN and analog FAXes and/or analog phones).
