Programming the Status Register System
The Data Questionable BERT Status Group is used to determine the specific event that set
bit 12 in the Data Questionable Condition Register. The Data Questionable BERT Status
Group consists of the Data Questionable BERT Condition Register, the Data Questionable
BERT Negative Transition Filter, the Data Questionable BERT Positive Transition Filter,
the Data Questionable BERT Event Register, and the Data Questionable BERT Event
Enable Register. The Data Questionable BERT Condition Register contains the following
bits:
Figure 1-42.
Bit Description
0 A 1 in this bit indicates that a no clock signal has been input to the BER CLK IN
connector for more than three seconds during a bit error rate test.
1 A 1 in this bit indicates that data signals input to the BER DATA IN connector have
not changed for a period of more than 200 clock signals during a bit error rate test.
2 A 1 in this bit indicates that the synchronization of the incoming data to the BER
DATA IN connector for the bit error rate test has been lost.
3
−10 Unused. These bits are always set to 0.
11 A 1 in this bit indicates that either the downconvertor or demodulator is out of lock.
12 A 1 in this bit indicates that the demodulator DSP amplitude is out of range.
13 A 1 in this bit indicates that BCH or TCH synchronization is not established.
14 A 1 in this bit indicates that a TCH midamble is not being received.
15 Always Zero (0).
