APPLICATIONS
HiGain HDSL2 systems provide a cost-effective, easy-to-deploy method for delivering DS1 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, T1 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 with otherHDSL2 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.

Figure 1. HDSL2 System Model
HIGAIN REGENERATORS
For applications without regenerators (doublers), the H2TU-C-202 is directly connected to an H2TU-R remote
unit by one HDSL2 cable pair. The H2TU-C-202 is compatible with all HiGain H2TU-Rs.
For regenerator applications, one to two regenerators may be used in the HDSL2 loop between the H2TU-C and
H2TU-R, for instance:
•The H2TU-C-202 List 1E can power one regenerator (H2RU-407 or H2RU-409) and a remote unit
(H2TU-R-402) for a total of two spans.
•If the H2TU-R is locally powered, the H2TU-C can power up to two regenerators for a total of three spans.
Future enhancements of the H2TU-C-202 will support regenerators.

VERIFICATION
Once the H2TU-C-202 is installed, verify that it is operating properly. To do this, monitor the four status LEDs.
Verification without a Downstream Device
If there is no downstream device 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 downstream devices (the LOOP LED flashes green).
Even if a downstream device is not present, the H2TU-C again attempts communication with downstream
devices until a downstream device is detected.
Verification with a Downstream Device
If a downstream device has been installed:
1Verify that the H2TU-C powers up. (The LOOP LED illuminates.)
2Verify that the H2TU-C attempts to communicate with downstream devices (the LOOP LED flashes green).
One of the following occurs:
•If downstreamdevices are successfully identified and the HDSL2 loop synchronizes, theH2TU-C LOOP
LED lights a steady green.
•If downstream devices are not successfully identified, the H2TU-C will:
–attempt communication again and the LOOP LED will keep flashing
–repeat the cycle until a downstream device is detected
Connect the H2TU-C- 202 to the maintenance terminal to monitor the alarm messages on the terminal.
3If there is more than one span, verify that each subsequent span synchronizes normally by monitoring the
LOOP LED.
4If a remote unit is installed, verify that the last span synchronizes normally. The H2TU-C LOOP LED should
light a steady green.
5Verify 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, then the DSX LED is off.
•If a valid DS1 signal is being supplied to the H2TU-C and H2TU-R, then DS1 alarm indications should
be absent and the LOOP LED should light a steady green.

Provisioning 152-202-115-04, Revision 04
10 April 21, 2000 H2TU-C-202 List 1E
PROVISIONING
There are two provisioning methods:
•Setting the DIP switch located on the board
•Use 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 HDSL2 maintenance screens (Figure 5 on
page 11). This gives 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.
The 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 11), do one of the following:
•Type the first letter of the menu.
•Use the arrow keys to select a menu, then press .
