The INTERCEPTOR 147 2 Mbit/s and Data Analyzer is a hand-held, battery-operated digital communications test cij instrument. It can perform in-service and out-of-service analysis on 2048 kbit/s circuits, 64 (or 56) kbit/s timeslots (including individual, adjacent, or non-adjacent timeslots), as well as physical layer testing at data interface access points. The front panel of the test instrument is arranged so that the test instrument is easy to use. To learn more about the functions of controls and indicators on the front panel, see Section 2, Instrument Description. To set up to test a digital communications circuit, see Section 3, Setup Categories. As you conduct a test, the test instrument provides a number of test results that provide information about the circuit under test. For information about the test results, see Section 4, Test Results. In addition to performing the tests and viewing the results, you can also connect a printer to the test instrument and print information regarding the test setup and test results. The information can be printed in a number of formats, including histogram format. For information regarding printing, see Section 5, Using a Printer. Additionally, the test instrument can be controlled through a remote controller such as a personal computer. For information regarding remote control, see Section 6, Remote Control. The INTERCEPTOR 147 includes the following key features: INTERCEPTOr 147 2 Mbit/s and Data Analyzer Operates at 2 Mbit/s, Nx64, Mx64, Nx56, Mx56 kbit/s, and Data Communications rates Measures 2 Mbit/s signal level Performs digital and VF channel analysis Displays 2 Mbit/s timeslot activity Automatically detects 2 Mbit/s framing and pattern Performs bit slip and frame slip analysis and stress testing of network timing (Option 147-1) Detects REBE (Remote End Block Error) bits in 2Mbit/s mode Measures round trip delay Provides a 16K test mode Transmits NTPM, LEPM, and programmable ISDN (Sa6) loop codes Displays and prints Sa6 messages Generates frequencies from 50 bit/s to 2.048 Mbit/s Transmits and displays Transmic 2G (C-Bit) loop codes Performs M.2100 in-service performance analysis Provides remote control commands for remote operation Stores and recalls setup configuration Stores and prints Results with/without Histograms Squelches prints when high error rate produces too many prints
