An identification code circuit for a receiving coil in a magnetic resonance imaging system, is embodied in a main coil. The circuit has a fixed resistance for generating the identification code of the main coil. The main coil has a socket for connecting a sub-coil, so that a coil plug of a sub-coil can be plugged into the socket for connecting to the main coil. The identification code circuit also has a regulating resistance and a sub-coil switch corresponding to the socket. The coil plug of the sub-coil is plugged into the socket to close the sub-coil switch, so that the values of the regulating resistance and said fixed resistance are added together to form a combined resistance value. After said main coil has been connected to a magnetic resonance imaging system, an identification code source voltage value across the combined resistance value is the identification code of the combined main coil and sub-coil. A receiving circuit identification code thus can be generated simply and with reduced cost.

The invention discloses a method and monitoring equipment for realizing association of a calling control protocol and a media control protocol. the method comprises a calling process performed by soft exchanging equipment of a NGN network aiming at public switched telephone network (PSTN) equipment; when determining the used circuit identifying code in the current calling process does not determine the calling association relation, according to the time interval of calling process message interaction carried out by the PSTN equipment and the soft equipment before the current calling process and during the calling process using the circuit identifying code, a destination node identifier is determined in each destination node identifier which is not determined the calling association relation; the destination identifier and the circuit identifying code are determined to form the calling association relation when the destination node identifier is judged to be associated with the media gateway control protocol events; the invention automatically studies the corresponding relation of CIC and TID under the condition that SS does not provide the corresponding relation of CIC and TID to a monitoring system, thus improving monitoring performance.
