INTERCEPTOR 147 2 Mbit/s and Data Analyzer
Applications
3. Set the CONFIGURATION category items
Set Framing to the format used on the 2048
kbit/s link under test (or set Framing to AUTO).
Set Data Leads RTS and DTR to ON.
Set LL and RL to OFF.
Set other applicable items, as appropriate.
4. TIMESLOTS category.
Select the timeslots which are to be demultiplexed
from the 2 Mbit/s circuit to the data interface
under test.
5. Check AUXILIARY category items
If you are using a printer, set all printer-related
setup items as desired. (For more information,
see Section 5). Check the Time and Date items
to verify they are set for the current time and date.
6. Connect to the TRANSMITTER connector
Using the appropriate TRANSMITTER
connector, connect the test instrument to the 2
Mbit/s side of the component/DCE under test.
7. Connect to the Data Interface connector
Using the appropriate data interface connector,
connect the test instrument to the data circuit that
is being tested.
Test Results
1. Observe the Data Interface LEDs and 147 front-
panel LEDs
Watch the DATA INTERFACE LEDs to verify
the proper DTE/DCE exchange takes place.
Check the STATUS & ALARMS LEDs to verify
proper detection of signal and framing.
2. Verify test configuration
To check circuit continuity, transmit a bit error
and verify it is received (by checking the Bit Errs
item in the LOGIC & TIME Results category).
