152-402-145-02, Issue 2 Overview OVERVIEW The HiGain® HDSL2 product family from ADC® is the industry’s first practical implementation of High-bit-rate Digital Subscriber Line 2 (HDSL2). ADC products are fully compliant with the HDSL2 standard. Providing full-rate T1 access using just a single copper pair, HDSL2 is a cost-effective solution that offers an open architecture. The open architecture inherent in HDSL2 guarantees interoperability, allowing simple and economic accommodation of network growth.
Overview 152-402-145-02, Issue 2 COMPATIBILITY The H2TU-R-402 is designed to mount in any 400 or 200 mechanics shelf. For a list of compatible shelves see “Appendix C - Compatibility” on page 35. APPLICATIONS HiGain HDSL2 systems provide a cost-effective, easy-to-deploy method for delivering T1 High Capacity Digital Service (HCDS) over a single copper pair. HiGain HDSL2 systems support a multitude of network connections and system models.

152-402-145-02, Issue 2 Viewing System Screens VIEWING SYSTEM SCREENS The H2TU-R-402 supports both local and remote logon through a maintenance terminal (ASCII terminal or PC running terminal emulation software) connected to its front-panel craft port. From the maintenance terminal you can access menus and screens that are replications of those viewed at the H2TU-C. You can view system settings and inventory, initiate loopbacks, and monitor performance.

Loopback Operation 152-402-145-02, Issue 2 LOOPBACK OPERATION HiGain HDSL2 has a family of loopback options for analyzing circuit functionality. The loopback signal is transmitted and returned to the sending device for comparison. This allows you to verify the integrity of the HDSL2 channels to the H2TU-C, the H2TU-C DSX-1 interface, and the DS1 channels to the customer.
152-402-145-02, Issue 2 Loopback Operation Table 10. Summary of HiGain HDSL2 Loopback Codes and Activation Methods Method of Activation Test Set Craft Port H2TU-C MODE/SEL X X X X X X DS1 signal from the customer is looped back to the customer at the H2TU-R. X X X DS1 signal from the customer is looped back to the customer at the H2TU-C. X X X Dual loopback at H2TU-C.
Loopback Operation 152-402-145-02, Issue 2 Special Loopback Commands In addition to the GNLB loopback command mode, a HiGain HDSL2 system can be configured for one of three special loopback command modes. These command modes, A2LB, A3LB, and A4LB, are selected from the ADC Options maintenance terminal screen or by using the MODE and SEL buttons on the H2TU-C front panel.
152-402-145-02, Issue 2 5 Loopback Operation Repeat Step 2. If the test passes, the problem is in the downstream direction. If it fails, the problem is in the upstream direction. Figure 22.
Loopback Operation 152-402-145-02, Issue 2 A2LB Test Procedures Using the codes listed in Table 11, a network tester can activate NLOC, NRG or NREM loopbacks (or SMJK, if enabled). A tester at the customer premises can activate CLOC, CRG, or CREM loopbacks. Table 11. Addressable Repeater Loopback Commands (A2LB) Name Description Binary Code (a) (Hexadecimal Equivalent) ARMING or NI LPBK (inband) Arming code 11000-11000 ...
152-402-145-02, Issue 2 4 Loopback Operation Once armed, the H2TU-R-402 can be looped back by sending Intelligent Office Repeater (IOR) LPBK activation code 1101-0011-1101-0011 (D3D3) for at least 5 seconds.
Loopback Operation 152-402-145-02, Issue 2 A3LB and A4LB Test Procedures The H2TU-C can be looped back by sending the Addressable Office Repeater (AOR) LPBK activation code 1111-1111-0001-1110 (FF1E) for at least 5 seconds. This causes the H2TU-R-402 to enter the NLOC state. The H2TU-C Loopback Time-out (LBTO) setting determines the duration of this loopback unless it is overridden by the reception of a second identical 16-bit loopup command before the timer expires.
