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 |
| |
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 |
