THE H2TU-C-388 LIST 1E
The HiGain®Solitaire™ product family is the industry’s first practical
implementation of High bit-rate Digital Subscriber Line 2 (HDSL2). When an
H2TU-C-388 List 1E line unit is used in conjunction with a HiGain Solitaire remote
unit (H2TU-R), the system provides 1.552 Mbps transmission on one unconditioned
copper pair over the full Carrier Service Area (CSA) range. The CSA includes loops
up to 12,000 feet of 24 AWG or 9,000 feet of 26 AWG wire, including bridged taps.
These line units can be usedwith HiGain Solitaire regenerators (H2RUs) to extend the
CSA range. Firmware version 3.0 or higher supports the use of regenerators.

INSTALLATION
To ensure proper installation of the H2TU-C-388, align the H2TU-C with the
enclosure slot guides, and slide the unit in. Push down on the front panel to properly
seat it.
POWER-UP SEQUENCE
When the H2TU-C powers up, the four-character display illuminates and reports
status messages.
If the H2TU-C is unable to communicate with the next span device, it displays various
alarm and status messages.
If the H2TU-C is able to communicate with the next span device, the following occurs:
1The Status LED flashes green while acquiring each device in the system, and
turns a steady green when the entire system is operating without any alarms. (The
T1 signal must be present.)
2The four-character display reports margin (SNR) readings (shouldbe ≥6 dB) and
loop attenuation (should be <35 dB @196 KHz).
3If any alarm conditions exist after the system powers up, these are reported on the
display. (The H2TU-C reports alarms if no T1 signal is applied.)
PROVISIONING
After installing the H2TU-C, perform these basic provisioning tasks by accessing the
Solitaire HDSL2 logon screen. Refer to the onscreen Help menu for navigational aids.
1Connect a maintenance terminal to the craft port (see front-panel illustration
inside), then press + to refresh the logon screen, if necessary.
2Select the Config menu, Date and Time, and type the date and time.
3Select the Inventory menu and type in the unit ID numbers.
4Change the settings of any system parameters, if necessary, by selecting the
Config menu, Standard Options or PairGain Options. (Configuration options
can also be set from the front panel using the MODE and SEL buttons. See the
“Front-Panel Configuration Options”table inside).
5Once the H2TU-C is successfully installed and provisioned, access the Monitor
or Performance menus to clear the Performance and Alarm History screens to
ensure useful data.
