Patent ID: 8483364

Claim:
An improved telecommunication system, comprising: a computer system connected to a system interface, a front-end interface block, a plurality of input interface lines, each of which connects corresponding clients to said front-end block, a commutation block, a control block that is connected to said front-end block directly and to said system interface via said communication block, an analyzer connected to said control block, to said computer system and to said commutation block; said telecommunication system, wherein: said control block and said communication block are characterized in that they have two operation mode: a “normal” mode and a “busy” mode, and they can be transferred from one mode to another and back under the control of said analyzer; said analyzer is capable: to analyze the signals transmitted by said system interface, and in the case if said analyzer detects predetermined failure condition, to switch said communication and control blocks from the “normal” operation mode to the “busy” mode, to control directly operation of said computer system, to return said communication and control blocks from “busy” mode to “normal” mode after analyzing signals of the system interfaces; said communication block is capable to block transmit/receive operation between said system interface and said control block.
