seated.

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 next span device, it displays various
alarm and status messages.
If the H2TU-C is able to communicate with the next span device, the following occurs:
1 The Status LED flashes red while acquiring each device in the system, and turns
steady green when the entire system is operating without any alarms. (The T1
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 Any alarm conditions that exist after the system powers up are reported on the
display. (The H2TU-C reports alarms if no T1 signal is applied.)
