Abstract

The interface unit is a message switch used in a telecommunication system between control and monitoring means and the system proper. It includes a set of USART's, one of which is a master and is connected to a link from the control and monitoring means, while the others are slaves which give access via output ports to various portions of the system. A message from the control and monitoring means passes via memory to a processor which determines the action needed, and emits a message via the appropriate slave USART to the appropriate part of the system. A message from the system, either in response to a message from the interface or generated in the system, is received via the appropriate port and is passed in a reverse manner to that just described to control and monitoring means. Messages generated in the system are usually alarms. <IMAGE> [GB2215557A]
