The HiGain H2TU-C-202 List 4E functions as the Central Office (CO) end of a
repeaterless T1 Transmission system when connected to a HiGain HDSL2 remote unit
(H2TU-R). Setting new standards for interoperability and efficiency, HiGain HDSL2
modules transmit a 1.544 Mbps T1 payload on one unconditioned copper pair over the
full Carrier Service Area (CSA) range.

NSTALLATION
To ensure proper installation of the H2TU-C, align the unit with the enclosure slot
guides and slide it in until it touches the backplane card-edge connector.
P
OWER
-
UP
S
EQUENCE
When the H2TU-C powers up, the four status LEDs illuminate and report status
messages.
If the H2TU-C 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
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 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.
Continued
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-202 List 4E
DSX-1 output ports to the cross-connect panel must be
grounded at both ends.
