Chapter 3 Description of LED Alarm Indicator

The chapter will show the description of LED indicators. Read the module silk-screen to check the LED
names. The LED indicators include:
When the module powers on, the Power LED indicator will light up in green.
If any one of the following 7 errors occurs, the corresponding indicator will show in red, and "All OK"
indicator will go off. If there is none of the following 7 errors, the "All OK" indicator will light up in
green.
The definitions of 7 types of errors which the receiver may occur are as follows:
1. QCRC – CRC error in Q sub-code data.
2. CCRC – CRC error in channel status data.
3. UNLOCK – PLL is not locked to incoming data stream.
4. V – Data Validity bit is set.
5. CONF – The logical OR of UNLOCK and BIP. The input data stream may be near error
condition due to jitter degradation.
6. BIP – Bi-phase encoding error.
7. PAR – Parity error in incoming data.
