<p>An interface between a long range communications network, including high capacity lines, such as T1 lines, and a local communications network, such as a fiber optic loop including subscriber interfaces, includes a CPU module processing alarm messages. A second processing module on the interface unit receives the alarm messages from the high capacity communications lines and includes a first-in-first-out queue storing alarm-type indicators for received alarm messages, and a second store for storing information concerning received alarm messages. A message packet is built in response to the alarm message type and the information concerning received alarm messages in the second store. The packet is then delivered to the CPU module when inter-module communications resources are available. The message packets are built after performing a selected one of a plurality of relevancy tests for determining whether relevant information exists in the second store for respective alarm message types. An appropriate message packet is composed if relevant information exists. If no relevant information exists, then no message packet is composed.</p> |
