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 stand ard. Pr ovid ing
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. HiGain HDSL2 uses the industry’s first HDSL2 chipset (ANSI T1/E1.4
compliant) developed by ADC.

HiGain HDSL2 products provide 1.552 Mbps t ransmission on on e unconditioned copper pair over the ful l Carrier
Service Area (CSA) range. The CSA includes loops up to 12,000 feet of 24 American Wire Gauge (AWG) wire
or 9,000 feet of 26 AWG wire, incl uding bridged taps.

FEATURES

The H2TU-R-402 List 4E remote unit is the customer side of a T1 transmission system.

• HDSL2 transmission features
– Lightning and power cross-protection on HDSL2 interfaces
– Full-duplex HDSL2 transmission on one pair at 1.552 Mbps
– Ultra-low wander (Stratum 1 compliant)

• Front-panel features
– HDSL and DS1 status LEDs
– Dual loopback control button
– DS1 access bridging jacks
– RS-232 craft port for connection to a maintenance terminal

• HiGain HDSL2 maintenance screens for inventory, provisioning, and troubleshooting
– High-performance, non-volatile performance monitoring
– Non-volatile alarm histories
– Performance Report Messaging (PRM) support for Supplemental PRM (SPRM) and Network PRM

(NPRM)

• System configuration options
– Selectable DS1 pre-equalizer
– Bipolar Violation Transparency (BPVT)
– Bit Error Rate (BER) alarm
– Remote provisioning
– Selectable loopback activation codes

• Digital Data Service (DDS) latching loopback

• Payload (PL) and HiGain (HG) loopback source identification

• Line or local power with sealing current option

• Metallic loopback self tests

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 pag e 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 .

• The service is deployed over one unconditioned, non-loaded copper pair.

• Conventional, inline T1 repeaters are no longer required.

• Cable pair conditioning, pair separation, and bridged tap removal are not re quir ed.

In general, HiGain HDSL2 systems:

• Operate effectively in the same cable binder g roup with other HDSL2 lines, HDSL, T1, ADSL, SDSL, POTS,

DDS, and other transmission schemes.

• Can be used with customers requiring DS1 service on a temporary or permanent basis.

• Provide a means of quickly deploying service in advance of fiber-optic transmission systems.

DS1 is used throughout this document to refer to either the remote unit’s DS1 interface or the
line unit’s DSX-1 interface.

Wear an antistatic wrist strap when installing the H2TU-R. Avoid touching components on the
circuit board.

1 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.

2 Align the H2TU-R with the enclosure slot guides and slide the unit in. Push the unit back until it touches the

backplane card-edge connector.

3 Place your thumbs on the front panel and push the H2TU-R into the card-edge connector.

VERIFICATION

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.

Verification with an Upstream Device

1 Verify that the H2TU-R powers up.

• 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.

2 Verify that the H2TU-R attempts to communicate with an upstream device (LOOP LED is flashing green).

One of the following occurs:

• If an upstream device is successfully identified and the HDSL2 loop synchronizes, the LOOP LED lights

a steady green.

• If upstream devices are not successfully identified, the H2TU-R continues to attempt communication

(LOOP LED flashes green) until an upstream device is detected.

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. If the Remote Provisioning option is
enabled at the H2TU-C, you can configure the circuit.

information about the HiGain HDSL2 screens , provisioning, and trouble shooting, 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.

CONNECTING TO A MAINTENANCE TERMINAL

To connect to a maintenance terminal:
1 Connect a standard 9-pin serial cable to the RS-232 craft port (Figure 1 on page 3) on the H2TU-R-402 front

panel.

2 Connect the other end of the cable to the serial port on the maintenance terminal.
3 Start a terminal emulation program such as ProComm (emulating a VT100 terminal).
4 Con figure the maintenance terminal to the following communication settings:

• 9600 baud

• No parity

• 8 data bits

• 1 stop bit

• Hardware flow control to OFF

5 If necessary, press + to refresh the HiGain HDSL2 logon screen.
