When the H2TU-C powers up, the four-character display illuminates and reports
status messages.
If the H2TU-C is not communicating with the H2TU-R, it displays various alarm and
status messages. If the H2TU-C is communicating with the H2TU-R, the following
occurs:
1 The Status LED flashes red while acquiring the H2TU-R and turns a steady green
when the entire system is operating with no alarms. (The DS1 signal must be
present.)
2 The front-panel display reports signal-to-noise ratio (SNR) margin readings
(should be ≥ 6 dB) and loop attenuation (should be ≤ 28 dB).
3 After the system powers up, alarm conditions that exist are reported on the
display. (The H2TU-C reports alarms if no DS1 signal is applied.)
