When the H2TU-C powers up, the four-character display illuminates and reports
status messages.
If the H2TU-C is unable to communicate with the H2TU-R, it displays various alarm
and status messages. If the H2TU-C is able to communicate 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.)
The four-character display reports margin (SNR) readings (should be ≥ 6 dB) and
2
loop attenuation (should be <35 dB @196 KHz).
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.)
