Applications
APPLICATIONS
7.1 OVERVIEW
You can use the INTERCEPTOR 147 in a variety of
testing applications for 2 Mbit/s and data rate signals. For
a description of the various testing scenarios, how to set up
for each testing situation, and how to interpret the test
results, see the appropriate subsection that describes the
appropriate 2 Mbit/s, Data, or Mux test.
7.2 IN-SERVICE MONITORING A 2048
KBIT/S CIRCUIT
The INTERCEPTOR 147 is an excellent tool for in-
service (non-intrusive) testing of 2048 kbit/s links. The
primary advantage of in-service testing is that the link
under test does not have to be removed from service. This
means that no unnecessary down time is incurred. In
addition, data- or time-specific problems can be hard to
isolate using out-of-service methods.
For an illustration of how to configure the INTERCEPTOR
147 to measure the overall performance of an in-service
2048 kbit/s link, see Figure 7-1. (The monitor point is
shown between the Network Terminating Equipment and
a Pulse Code Modulation Multiplexer.)
