7 CHAPTER 2: Introduction 2. Introduction 2.1 Overview The BRTS-100 ISDN Test Set is a portable, hand-held, communication-line tester that helps you troubleshoot and verify ISDN S/T interface lines (see Figure 2-1). The Test Set supports a variety of comprehensive tests designed to help telephone and ISDN craft technicians isolate line problems.
8 BR TS-100 ISDN TEST SET Figure 2-1. The BRTS-100 ISDN T est Set. 2.3 Features This compact, rugged ISDN S/T interface line test set provides many essential diagnostic functions. It’s easy to use, too, requiring very little knowledge about complex ISDN protocols.
9 CHAPTER 3: Operation 3. Operation 3.1 Overview You can operate the BRTS-100 ISDN Test Set in a variety of modes. Select them by turning the selector dial on the left of the unit (see Figure 3-1). The indicator lights (LEDs) on top of the unit indicate test results.

12 BR TS-100 ISDN TEST SET To connect the Test Set in a point-to-point configuration, simply connect the 8-pin plug to either the A or B port located on top of the unit. To connect the Test Set in a passive bus configuration, connect the line from the NT1 to either the A or B port, and connect the termi-nal to the other port.
13 CHAPTER 3: Operation NOTE: In reverse mode, the light indicators are opposite. AUXILIARY POWER LIGHT — Indicates the presence and polarity of auxiliary power. Green light — Auxiliary power present, normal polarity. Red light — Auxiliary power present, reverse polarity.
14 BR TS-100 ISDN TEST SET 4. T est Procedures 4.1 Overview This chapter gives you several suggested test procedures. However, it is by no means the only way to use the Test Set to isolate trouble or to verify lines. NOTE: The following procedures assume certain conditions exist (that procedures are followed in the correct order.
15 CHAPTER 4: T est Procedures Figure 4-2. T est Configuration 2. Test Configuration 2 — Passive Bus (Figure 4-2) To put the terminal in the Passive Bus Test Configuration: 1. Disconnect the terminal. NOTE: With a passive bus, the S/T interface may disrupt the operation of the other devices on the bus.
16 BR TS-100 ISDN TEST SET 4.2 Comprehensive T roubleshooting Procedure This troubleshooting guide is for the user who is either installing a new line and wants to verify the S/T interface, or has a problem with an in-service ISDN terminal.

18 BR TS-100 ISDN TEST SET 13. a. If the terminal works, there’s no need to proceed any further. b. If the terminal does not work, proceed to step 14. 14. Perform the PAIR REVERSAL test procedure (see page 22). 15. Put the circuit into its normal operating configuration.
19 CHAPTER 4: T est Procedures 4.3 Check Power Some (not all) ISDN terminals require power from the S/T interface. This procedure verifies that power is received properly at the S/T interface. See Figure 4-5 for an outline of the functions performed in this test.
20 BR TS-100 ISDN TEST SET Figure 4-5. Check power flow chart. 4.4 Check Loop This procedure checks for physical impairments in the S/T interface. See Figure 4-6 for an outline of the functions performed during this test.
21 CHAPTER 4: T est Procedures With the Check Loop procedure, first check to see if the transmit pairs (pins 3 and 6) and the receive pairs (pins 4 and 5) are reversed. 1. Put the Test Set in REVerse mode; LINE button should be in. 2. Put circuit in the Point-to-Point NT1 Test Configuration (Test Configuration 1).

25 CHAPTER 4: T est Procedures 10. Put the Test Set in the CONTINUITY Test Mode. 11. a. If the Green Test Status light goes on, there is a physical connection between the terminal and the NT1. b. If the Red Test Status light goes on, there is no continuity on the receive pair between the terminal and the NT1.
26 BR TS-100 ISDN TEST SET 4.5 Passive Bus—Check T erminations When you’re using a passive-bus configuration, it’s imperative that the last device on the bus be terminated at 100 ohms. The other devices on the bus must be left unterminated. Termination should be an option on each ISDN terminal.
27 CHAPTER 4: T est Procedures 1. Determine which devices are the first and last devices on the bus. The first device is the one closest to the NT1. The last device is the one furthest from the NT1. See Figure 4-8 for an example of proper device termination.

29 CHAPTER 4: T est Procedures 4.6 Pair Reversal When you use the passive-bus configuration, it’s imperative that all the transmit pairs (from terminal) be wired the same. That is to say, pins 3 and 6 from each terminal on the bus must be wired to pins 3 and 6 of the NT1 respectively.
30 BR TS-100 ISDN TEST SET b. If the Red Test Status light goes on, the terminals’ wires are crossed— pin 3 of terminal is electrically connected to pin 6 of the other terminal. At this point, you should check the wiring of both terminal A and terminal B.

35 CHAPTER 5: T echnical Reference 5. T echnical Reference 5.1 Power-Source Indicators The Phantom Feed light indicates the presence and polarity of battery power. In NORMal mode, the Test Set verifies that the terminal’s transmit pairs are positive and its receive pairs are negative.
36 BR TS-100 ISDN TEST SET 5.2 Activation/Deactivation Modes The following information provides the steps that lead to an Active Link state and subsequent Activation/Deactivation modes (Figure 5-2) between the Test Set (TE) and an NT device. The Test Set uses this Activation/Deactivation procedure in Line Test, Transmit, and D Activity modes.
37 CHAPTER 5: T echnical Reference Figure 5-3. Info frames. Line T est/T ransmit (See Figure 5-4) Line Test and Transmit are exactly the same test. The test is conducted as follows. 1. Upon pressing the INITIATE button, the Test Set tries to establish an ACTIVE link with the NT1.
38 BR TS-100 ISDN TEST SET Figure 5-4. T ransmit and line test. D Activity (See Figure 5-5) The D Activity test is designed to run when the Test Set is bridged onto the S/T interface with an ISDN terminal. D Activity will monitor the Echo bits for any D channel data transmitted by the terminal.
39 CHAPTER 5: T echnical Reference Figure 5-6. CCITT 1.430. 5.3 AC Impedance As shown in Figure 5-6, CCITT recommends that the AC impedance at 20 to 30 KHz should be greater than 2.5K ohms. To detect this, the Test Set puts an R-sense resistor in series with the device under test (Figure 5-7).

41 CHAPTER 5: T echnical Reference 5.5 Speaker The incoming frequency to the speaker is divided by eight. Since ISDN signals are transmitted at 96 KHz, it has to be reduced in order to be heard over the speaker. When the Test Set is in TRACE TONE mode, the incoming frequency to the speaker is divided by four.
42 BR TS-100 ISDN TEST SET Appendix: Maintenance The Test Set requires very little maintenance other than replacing the 9-VDC battery periodically and possibly replacing one or both of the two 8-pin RJ-45- type jack connectors. NOTE: Average battery life is approximately 15 hours of continuous use.
43 APPENDIX: Maintenance 8-Pin Jack Replacement These connectors need to be replaced only when connections no longer permit a secure-tight connection or when connectors are damaged. In standard use, however, these connectors shouldn’t ever need to be replaced.
