INTERCEPTOR 147 2 Mbit/s and Data Analyzer
9. TRANSMITTER connector
Using the appropriate TRANSMITTER
connector, connect the test instrument to the
transmit direction of the circuit that is being
tested.
Test Results
1. Check the STATUS & ALARMS LEDs
Verify proper detection of signal, framing, pattern,
and absence of alarms.
2. Check the SUMMARY Results for any errors or
events
3. Check the G.821 or bit error results
At the end of the circuit commissioning test
period, record the bit error results or the G.821
performance analysis results as desired. Check
the results to determine if they meet acceptable
limits so that the circuit can be qualified.
4. If desired, print histograms and results

7.7 MONITORING 2048 KBIT/S CIRCUITS
FROM DS3 ACCESS POINTS
You can use the INTERCEPTOR 147 in conjunction with
a TTC T-BERD 305, or a T-BERD 310 DS3 Analyzer
equipped with 2048 kbit/s drop capability, to monitor a
2048 kbit/s circuit from a DS3 (45 Mbit/s) signal access
point. For example, when you are troubleshooting a 2048
kbit/s North America-to-Europe gateway circuit on the
North American side, the INTERCEPTOR 147 (located at
the DS3 monitor point) works with a second 2048 kbit/s
test set (located at a 2048 kbit/s circuit input) to perform
an out-of-service test. However, the INTERCEPTOR 147
