THE H2TU-C-319 LIST 2E
The ADC®HiGain®product family is the industry’s first practical implementation of
High bit-rate Digital Subscriber Line 2 (HDSL2). When an H2TU-C-319 List 2E line
unit is used in conjunction with a HiGain 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 used with
HiGain regenerators (H2RUs) to extend the CSA range. Regenerator support will be
available in future product enhancements.

INSTALLATION
To install the H2TU-C-319, align the H2TU-C with the slot guides, then slide the line
unit into the enclosure. You should hear a snap when the H2TU-C-319 is properly
seated.
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:
1While as devices in the system are being acquired the Status LED flashes red.
Once the entire system is operating without any alarms (the T1 signal must be
present), the Status LED illuminates steady green.
2The four-character display reports margin (SNR) readings (shouldbe ≥6 dB) and
loop attenuation (should be <35 dB @196 KHz).
3If an alarm condition exists after the system powers up, it is 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
HiGain 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 ADC Options. (Configuration options can
also be set from the front panel using the MODE and SEL buttons.)
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.
