Abstract:
1. A media converter for converting from one type of media to another, said media converter comprising: a first physical-layer interface adapted for connection to a first transmission medium; a second physical-layer interface adapted for connection to a second transmission medium; a memory connected between the first and second physical-layer interfaces, for temporarily storing data; a determiner for determining whether a signal received at one of the first and second physical-layer interfaces comprises one of data to be stored in the memory for transmission to the other of the first and second physical-layer interfaces and a trigger signal to activate a test mode of the media converter; and a controller responsive to the determiner determining that the received signal comprises data, for causing the received signal to be stored in the memory for transmission to said other of the first and second physical-layer interfaces, and responsive to the determiner determining that the received signal comprises the trigger signal, for causing a test response signal to be said one of the physical-layer interfaces back to the source that transmitted the trigger signal.
