The HiGain HDSL2 product family from ADC 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.
Overview OMPATIBILITY 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 PPLICATIONS HiGain HDSL2 systems provide a cost-effective, easy-to-deploy method for delivering T1 High Capacity Digital Service (HCDS) over a single copper pair.

Front Panel Front-panel Feature Function List number Identifies the list number of the H2TU-R-402. Alarm (ALM) LED Shows alarm states for remote and local Loss of Signal (LOS). Steady red Indicates a Loss of Signal (LOS) condition at the T1 input of the H2TU-R-402. Blinking Indicates an LOS condition at the T1 input of the H2TU-C line unit.
152-402-145-02, Issue 2 NSTALLATION H2TU-R-402 Figure 2. Installing the H2TU-R-402 List 4E Wear an antistatic wrist strap when installing the H2TU-R. Avoid touching components on the circuit board. Check the setting of the SCURR switch. The default setting is disabled (up position). If the H2TU-R is locally powered, and your application requires sealing current, place the SCURR switch in the down position.
Installation ERIFICATION Verification without an Upstream Device Verify that the H2TU-R powers up. The following should occur: • The front-panel ALM LED is a steady red. • The LOOP LED is flashing green. • If receiving a DS1 signal, one of the DS1 framing LEDs (ESF or SF) and one of the DS1 line code LEDs (B8ZS or AMI) is a steady green.
Initial provisioning of the HiGain HDSL2 system is performed at the H2TU-C line unit. For more information about the HiGain HDSL2 screens, provisioning, and troubleshooting, download the appropriate H2TU-C line unit user manual from the ADC website at www.adc.com. To order a hard copy, please contact your sales representative.

Loopback Operation OOPBACK PERATION 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. Loopback options include: •...

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. Once a loopback mode is activated, other loopback commands can be sent by a test set connected to the craft port on the H2TU-C or H2TU-R front panel.

Loopback Operation 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 ARMING or NI LPBK (inband) ARMING or NI LPBK (ESF Datalink)

152-402-145-02, Issue 2 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. You should observe the following activation response pattern: 2 seconds of AIS (all ones pattern) 2 seconds of returning data pattern Logic errors (including the frame bit) occurring in the returned pattern comprising: –...
Loopback Operation 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.
