E1A E1B PLAN REMOTE ERROR

Figure 1-7. BBP Front Panel with Door Open

As a rule, a green LED indicates a normal situation, a red LED indicates an error situation, and a yellow LED indicates a configuration option. LEDs indicating overall system integrity are listed below.

Self Test	Blinking red if the self-test has completed and failed; Solid red if
	self-test is in progress or did not complete
Power	Green if DC voltage is applied

The LEDs associated with the E1 interfaces are listed below.

CV/CRC	Red if the incoming E1 stream contains code violations, or a CRC
	error
LOS/OOF	Red if there is no signal present at the E1 interfaces or if framing
	synchronization is lost
Loopback	Solid yellow if the E1 interfaces are in local line loopback. Blinking
	yellow if the E1 interfaces are in link loopback.
ALM	Solid red if a UA1 is detected at the incoming E1, blinking red if a
	remote alarm signal is found

The functions of the LEDs which relate system configuration information are listed below.

Frequency Plan A	Yellow if frequency plan A is selected
Frequency Plan B	Yellow if frequency plan B is selected
Remote Test Active	Yellow if the remote test is active
Remote Test Fail	Red if the remote test failed
