5. USING THE INSTRUMENT FOR 
MONITORING 
5.1. About this chapter 
This chapter gives detailed information of all parameters used to setup the instrument 
for monitoring D channel traffic in an ISDN access and signalling over POTS access. 
There are two monitoring modes:   
► 
The instrument is capable of monitoring the traffic while executing a test. 
Throughout this manual this mode is referred to as “background mode”. 
► 
The instrument can be set-up in a way that it monitors all traffic on the 
selected S interface. Throughout this manual this mode is referred to as “ high 
impedance mode”. 
The parameters that can be set up in both modes are the same: filters and control of 
buffer. In both cases the resulting trace can be stored and analyzed on the screen. 
Filters are different for monitoring over POTS. Monitoring navigation is illustrated in 
Fig. 5-1.
