The NET LED remains constant • Incoming RAI or UAI. amber/yellow.

•Check to see if the LRU4240 is receiving a RAI alarm or an AIS alarm.

•Make sure the remote/far end system is receiving a proper E1 signal. If it is not, it will be generating a RAI alarm towards your equipment.

•If the system is still receiving a RAI alarm, place the E1 test set or the E1 loopback plug on the RJ-48C or BNC socket on the back of the LRU4240. If the RAI alarm stops, contact your service provider for assistance.

•If, after all above steps have been satisfied, your LRU4240 still shows a yellow NET LED, call Black Box Technical Support for assistance.
