The ADC HiGain product family is the industries first practical implementation of
High-bit-rate Digital Subscriber Line 2 (HDSL2). When an H2TU-C-202 line unit is used
in conjunction with a Higain remote unit (H2TU-R), the system provides 1.552 Mps
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.

NSTALLATION
To ensure proper installation of the H2TU-C-202, align the unit with the enclosure slot
guides and slide it in until it touches the backplane card-edge connector.
P - S
OWER UP EQUENCE
When the H2TU-C-202 powers up, the four status LEDs illuminate and report status
messages.
If the H2TU-C-202 is able to communicate with the H2TU-R, the following occurs:
1 The LOOP 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 DS1 signal must be present.)
2 If any alarm conditions exist after the system powers up, these are reported on the
appropriate status LED (see the descriptions of the four status LEDs on the
front-panel illustration inside).
P
ROVISIONING
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.
1 Connect a maintenance terminal to the craft port (see front-panel illustration
CTRL R
inside) then press + to refresh the logon screen, if necessary.
2 Select the Config menu, Date and Time, then type the date and time.
3 Select the Inventory menu, then type in the unit ID numbers.
4 Change the settings of any system parameters, if necessary, by selecting the
Config menu, Standard Options or ADC Options.
5 Once the H2TU-C-202 is successfully installed and provisioned, access the
Monitor, Performance or Event Log menus to clear the Performance, Alarm
History or Event Log screens, or use Master Clear in the Config menu.
