Diagnostics 5 5 This chapter explains using diagnostics to locate and resolve problems with the Solo E1 DSU and/or equipment connected to the Solo E1 DSU. Verify your connections and circuits to troubleshoot problems by running built-in diagnostic and pattern tests. These tests can isolate problems when they occur. In most cases, you wonÕt need to use test equipment. Diagnostic Considerations Running a test interrupts payload trafÞc.
5 Figure 5-1 Menu-9 Diagnostics Table 5-1, Table 5-2, and Table 5-3 describe the Menu-9 Diagnostics parameters of Figure 5-1. Shortcut When you are in Menu-9, Next Test (Fraction) is automatically highlighted. 1. Press Enter. Use the UP or DOWN arrow keys or type a test index to select a new test: 2. There are 20 tests, if you know the number, type it in, otherwise toggle through the menu choices. If the number is a single digit, you must type a 0 in the Þrst space. The number you type is not visible.
5 4. Type y for yes and the test will begin. The tests available in the Next Test parameter are shown in Table 5-2. Table 5-1 Meru-9 Diagnostic Parameters Parameter Value Description Pattern Test Status Idle Searching Locked Relocked Locked Seconds is displayed if the current pattern test is locked. The Locked Seconds is a 16-bit counter which is reset to 0 if the current pattern is unlocked. The counter label will change to Relocked Seconds if the current pattern is unlocked and then relocked.

5 Possible messages are RUNNING SELF TEST, SELF TEST PASSED or ERROR , where is one of the error codes shown in Table 5-4.
5 The Loop DTE Test The Loop DTE test veriÞes the operation of the DSU/CSU and the associated DTE cabling and equipment by looping the E1 network transmit signal through a 4 000 foot simulated line to the DSU/CSU network receive circuitry (Figure 5-2 shows both Full and Fractional Bandwidth). The DTE equipment should receive the same signal (a series of 1s and 0s) it transmitted. The E1 network transmitter continues to transmit the pattern toward the network while the DSU/CSU is in DTE loopback.
5 Alternate Option The signal sent is exactly opposite the signal sent in standard mode. This is useful for testing a remote unit that has other equipment in between the local and remote. The other equipment does not recognize the signal and passes it through to the remote. NOTE: The DTE device must be able to recognize its own test pattern for Loop DTE to verify the DTE cabling and equipment. Without this capability, the Loop DTE test can only verify the DSU/CSU.
5 It loops the payload data received from the E1 network back toward the network. Before it is looped back, the data is regenerated and a new framing pattern is inserted. Thus, the proper E1 framing of the DSU/CSU and network can be veriÞed. Local Solo E1 DTE Remote Solo E1 DSU CSU Data Port Network Interface GR618 CSU Figure 5-4 Data Port Network Interface DSU Loop Payload Test The individual channel loop payload loops a selected ÒfractionÓ of the E1 signal toward the network.
5 NOTE: To run multiple fractional loop payload tests, you must first terminate any current tests (other than a fractional payload test). The Loopup/Down Remote Tests The loopup remote test puts the remote DSU/CSU into network loopback. Once in loopup remote, test patterns can be sent to verify the Bit Error Rate (BER) performance of the bidirectional E1 network signal (Figure 5-5).
5 Pattern Tests Table 5-2 contains a list of these pattern tests. The QRW Test QRW (Quasi Random Word) is a pseudo random signal which catches problems not exposed by other test patterns. The DSU/CSU transmits a QRW pattern to the E1 network, the remote system loops it back to the DSU/CSU which monitors the signal for QRW bit errors. You can also use the QRW code to isolate a E1 network problem to a speciÞc transmission direction.
5 The Send 1:4 (or alternate) Test Use when the loopup remote test fails to put the remote system into loopback. You can determine if the failure is an intermittent or a hard failure by continuously sending the 1:4 code, and monitoring the network status to see if the pattern is being received. The selections are available on the full bandwidth and on the DATA ports. The full bandwidth code puts the remote system into full network loopback.
5 Status LEDs Use the LEDs to verify the test progress (Table 5-5). Table 5-5 Front Panel LEDs Status LED Condition Description PWR/TEST Turns yellow Test is running. The test is identified in current test. PWR/TEST Blinks Self-test in progress. ACK Blinks quickly for 3 seconds Loopup remote or loopdown remote is successful.
5 DTE/NET Loopback To start this test: 1. Press DTE/LPBK to start the DTE/NET loopback test. 2. Press DTE/LPBK again to end the test. Loopup Remote and Loopdown Remote To start this test: 1. To run the test, press REMOTE LPBK UP to loopup the remote Solo E1 DSU. 2. To loopdown the remote Solo E1 DSU, press REMOTE LPBK DOWN. When a test is running, the PWR/TEST LED shows yellow.
5 The pattern tests are listed in Table 5-7. Table 5-7 Pattern Tests Pattern Test Description Send All Ones Use this test to expand circuit as a maximum density signal, it is also used to test synchronization circuits. Send All Zeroes Use to test the zero suppression circuit. As a minimum density signal, it is also used to test synchronization circuits. Send 1:1 This pattern sends alternate ones and zeros. It is used in testing for bridge taps.

Make sure Block all Alarms is set to No in Menu-7 Alarm and the occurring alarm is set to Enabled. Current Tests Terminate Without My Intervention Make sure the Solo E1 DSU is set to run the test for an unlimited amount of time. Test length options are 15 min, 1 min, 60 min, Unlimited.
6 If the Solo E1 DSU still does not loopup, use your E1 test set to inject a fractional loopback signal into the payload you wish to loopup. The NET LED does not Illuminate Run a lamp test from Menu-9 Diagnostics to make sure the LEDs are working. Make sure the E1 line from your service provider is connected to the DA-15 female connector on the back of the Solo E1 DSU. Remove the E1 line from the back of the Solo E1 DSU and place the E1 test set in its place.
6 If the yellow alarm is disabled, this condition is ignored. In the alarm menu, indicate ÒRAIÓ for Network status. The CTS line on Data DTE is deasserted. The NET LED Flickers Intermittently between Red, Yellow and Green Make sure the timing source is properly conÞgured. Timing should be set to NETWORK if the network is the source. If it is not the source, timing should be set to INTERNAL at one E1 end, and NETWORK at the other end.
6 The DATA Port RTS/CTS LEDs do not Illuminate If the DTE device does not support the RTS or DTR signalling, set the port DTE loss to None (defaultÑRTS) in the Data DTE ConÞguration menu. The CTS LED should light and remain lit. RTS and DTR are signals sent from the DTE device connected to the Data Port. Run a lamp test from Menu-9 Diagnostics to make sure the LEDs are working. The DTE Device Shows Intermittent Errors You may have a timing error, check network statistics.
