LTPH-TP-1005-02, Issue 2 Overview
H2TU-C-202 List 3E February 28, 2001 1
OVERVIEW
The H2TU-C-202 List 3E line unit is the Central Office (CO) side of a T1 transmission system. The HiGain®
HDSL2 product family is fully compliant with the HDSL2 standard ANSI T1.418. Providing full-rate T1 access
using 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

COMPATIBILITY
The H2TU-C-202 List 3E is designed to mount in 200 mechanics shelve. For a list of compatible shelves, see
“Appendix C - Compatibility”on page 59.
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 (see Figure 1 on page 3).
•The service is deployed over one unconditioned, non-loaded copper pair.
•Conventional, inline, DS1 repeaters are no longer required.
•Cable pair conditioning, pair separation and bridged tap removal are not required.
Each loop has no more than 35 dB of loss at 196 kHz, with driving and terminating impedances of 135 Ω. In
general, HiGain HDSL2 systems:
•Operate effectively inthe same cable binder group withother 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.

INSTALLATION
Figure 4. Installing the H2TU-C-202 List 3E
1Align the H2TU-C with the enclosure slot guides and slide the unit in until it touches the backplane card-edge
connector.
2Place your thumbs on the H2TU-C front panel and push the H2TU-C into the card-edge connector until it
snaps into its seated position.
Upon receipt of the equipment, inspect the contents for signs of damage. If the equipment has
been damaged in transit, immediately report the extent of damage to the transportation
company and to ADC.
When installing an H2TU-C circuit card, be sure to wear an antistatic wrist strap. Avoid touching
components on the circuit board.
To comply with the intrabuilding wiring requirements of GR-1089 CORE, Section 4.5.9, the
shields of the ABAM-type cables that connect the H2TU-C DSX-1 output ports to the
cross-connect panel must be grounded at both ends.

8 February 28, 2001 H2TU-C-202 List 3E
VERIFICATION
Once the H2TU-C-202 is installed, verify that it is operating properly. To do this, monitor the four status LEDs.
(See Table 1 on page 5 for status LED descriptions.)
Verification without an H2TU-R Remote Unit
If there is no H2TU-R remote unit installed:
1Verify that the H2TU-C powers up. The four status LEDs illuminate and report the status. (See Table 1 on
page 5 for status LED descriptions.)
2Verify that the H2TU-C attempts to communicate with a remote unit (the LOOP LED flashes green). Even if
a remote unit is not present, the H2TU-C continually attempts communication with remote unit until a remote
unit is detected.
Verification with an H2TU-R Remote Unit
If an H2TU-R remote unit has been installed:
1Verify that the H2TU-C powers up. (The LOOP LED illuminates.)
2Verify that the H2TU-C attempts to communicate with remote unit (the LOOP LED flashes green). One of
the following events occurs:
•If the remote unit is successfully identified and the HDSL2 loop synchronizes, the H2TU-C LOOP LED
lights a steady green.
•If remote unit is not successfully identified, the H2TU-C continues to attempt communication and the
LOOP LED continues to flash until a remote unit is detected.
3Verify that a valid DS1 signal has been applied to the H2TU-C and the H2TU-R.
•If no DS1 signal is being applied to the H2TU-C or H2TU-R inputs, the LOOP LED flashes red.
•If a valid DS1 signal is being supplied to the H2TU-C and H2TU-R, the LOOP LED illuminates steady
green.

LTPH-TP-1005-02, Issue 2 Provisioning
H2TU-C-202 List 3E February 28, 2001 9
PROVISIONING
There are two provisioning methods:
•Setting the DIP switch located on the H2TU-C-202 circuit card
•Using a maintenance terminal (ASCII terminal or a PC running terminal emulation software) connected to
the H2TU-C craft port (or to an HMU craft port) to access the HiGain maintenance screens (Figure 5 on
page 10). Using a maintenance terminal allows you full access to all H2TU-C status, history, inventory, and
provisioning screens.
USING AMAINTENANCE TERMINAL
Connecting to a Maintenance Terminal
The craft port on the front panel allows you to connect the H2TU-C-202 to a maintenance terminal (ASCII
terminal or PC running a terminal emulation program). Once connected to a maintenance terminal, you can access
the maintenance, provisioning, and performance screens.
To connect to a maintenance terminal:
1Connect a standard 9-pin terminal cable to the RS-232 craft port (Figure 2 on page 4) on the H2TU-C-202
front panel.
2Connect the other end of the cable to the serial port on the maintenance terminal.
3Start a terminal emulation program such as ProComm (emulating a VT100 terminal).
4Configure the maintenance terminal to the following communication settings:
•9600 baud
•No parity
•8 data bits
•1 stop bit
•Hardware flow control to OFF
5If necessary, press + to refresh the HiGain HDSL2 logon screen.
Logon Screen
The HiGain HDSL2 maintenance terminal screens allow you to monitor, provision, and troubleshoot an
H2TU-C-202 system.
To select a menu from the HiGain HDSL2 logon screen (Figure 5 on page 10), do one of the following:
