call tracking system
For documenting problems, some organizations use a software program known as a(n) ______(also informally known as help desk software).
cable performance tester
A sophisticated _____ will include a TDR (time domain reflectometer) that issues a signal on a cable and then measures the way the signal bounces back (or reflects) to the TDR.
