Installation

Verification without a Downstream Device

If there is no downstream device installed:
1 Verify that the H2TU-C powers up. The four status LEDs illuminate and report the status. (See
page 4 for a list of status LED messages.)
2 Verify 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 attempts communication with downstream devices
until a downstream device is detected.

Verification with a Downstream Device

If a downstream device has been installed:
1 Verify that the H2TU-C powers up. (The Loop LED illuminates.)
2 Verify that the H2TU-C attempts to communicate with downstream devices (the Loop LED flashes green).
One of the following occurs:
• If downstream devices are successfully identified and the HDSL2 loop synchronizes, the H2TU-C Loop
LED will be 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.
3 If there is more than one span, verify that each subsequent span synchronizes normally by monitoring the
Loop status LED.
4 If a remote unit is installed, verify that the last span synchronizes normally. The H2TU-C Loop LED should
stay steady green.
5 Verify that a valid DS1 signal has been applied to the H2TU-C and the H2TU-R.
•
If no DS1 signal is being applied to either the H2TU-C or the 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 steady green.

ROVISIONING
After a successful installation, complete the following tasks:
1 Set the date and time (see
2 Set the circuit ID number (see
3 Make any desired changes to configuration (see
4 Clear the Performance and Alarm history screens and Event Log to remove miscellaneous data acquired
during startup. This ensures the collection of accurate and meaningful data (see
