<P>PROBLEM TO BE SOLVED: To provide multiplexed transmission network equipment which can transmit and receive one of two kinds of signals, for example, differing in priority stably, without being affected by communication traffic of the other signal. <P>SOLUTION: A first pulse transformer unit (20) of a multiplexed transmission network equipment (10) includes at least two first processing unit side coils (42) having opposite ends to which first signal terminals (43) of a first processing unit (22) are connected and at least two first input/output unit side coils (40) having opposite ends to which a pair of input/output terminals (38) of an input/output unit (12) are connected, while a second pulse transformer unit (24) includes a second processing unit side coil (47) having opposite ends to which second signal terminals (48) of a second processing unit (26) are connected and a second input/output unit side coil (45) having one end connected to the middle of a coil on one side of the first input/output unit side coils (40) of the first pulse transformer unit (20) and the other end connected to the middle of a coil on the other side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
