Page 54: Loopback Operation
• Test Set H4TU-C Network ADC HDSL4 supports multiple loopbacks, but a single loopback is the preferred method. HDSL4 automatically rejects activation of closed loop looopbacks. For example, an NREM and CREM cannot be activated at the same time. Table 17 on page... -
Page 55: Generic Loopback Commands
LTPH-UM-1031-03, Issue 3 Generic Loopback Commands The HDSL4 Generic Loopback (GNLB) commands allow you to use inband codes to loop up either NLOC (4-in-7) or NREM (3-in-7) towards the network. In addition, these inband codes loop up CREM (6-in-7) or CLOC (5-in-7) towards the customer. Either loopup condition can be terminated (looped down) with the 3-in-5, SMJK loopdown code. -

Page 60: A3Lb Test Procedure
Testing To perform the GNLB loopback test procedure: Have the CO tester send the NREM (3-in-7) inband loopup code for 5 seconds. You should observe the NREM message on the front-panel display. (The Status LED on the front panel should be green, and the loopback mode should also be identified on the Monitor screen.) Have the CO tester transmit a DS1 test signal towards the H4TU-C and verify that the returned (looped) signal to the test set is error-free. -
Page 61: A5Lb Test Procedure
LTPH-UM-1031-03, Issue 3 A5LB Test Procedure Using the codes listed in Table 18, a network tester can activate NLOC or NREM loopbacks (or SMJK, if enabled). A tester at the customer premises can activate CLOC or CREM loopbacks. Table 18. A5LB Addressable Repeater Loopback Commands Name ARMING or NI LPBK (inband) ARMING or NI LPBK (ESF Data Link) - Page 62 H4TU-C generates 231 (NLOC and CREM) ID bit errors. As a result, the H4TU-C may indicate one more or one less bit error, depending on the test set type and the number of frame bits contained in the block of errored bits. To avoid this uncertainty, ADC recommends sending unframed IR commands.
- Page 63 LTPH-UM-1031-03, Issue 3 The Time-Out Override function is only valid for the current active loopback. The automatic time-out timer is restored during subsequent loopback sessions. Once the test is complete, do one of the following: • If the system is to loopdown but remain armed, send the IR (Intelligent Repeater) LPDN code (universal loopdown).

Appendix A - Specifications OWER ONSUMPTION The three most important power parameters of an H4TU-C are its maximum power consumption, maximum power dissipation, and maximum current drain. Table 20 describes line-powered and locally powered (remote) circuits on the maximum reach condition (34 kft.) using 26 AWG wire. -
Page 69: Maximum Current Drain
LTPH-UM-1031-03, Issue 3 AXIMUM URRENT The maximum current drain is the maximum current drawn from the shelf power supply when it is at its minimum voltage (-42.5 ). This determines the shelf fusing requirements. Use the -42.5 Vdc current data in determine the shelf fusing requirements for your particular H4TU-C applications. -
