If an H2TU-R remote unit has been installed:
1 Verify that the H2TU-C powers up. (The front-panel display illuminates and reports various status messages.)
2 Verify that the H2TU-C attempts to communicate with the remote unit (status LED flashes red). One of the
following then occurs:
• The H2TU-C detects and synchronizes with the remote unit. If no DS1 signal is being applied at either
end, then the appropriate DS1 alarms (LLOS or RLOS) are reported on the front-panel display. The status
LED flashes red until the DS1 signal is applied at both ends. The status LED then turns to a steady green
and normal margin messages are reported on the front-panel display.
•
If the remote unit is not detected, the H2TU-C reports four-character status messages. The H2TU-C
attempts communication again and reports four-character status messages. The H2TU-C repeats this
cycle until a remote unit is detected.
