Diagnostics
This section describes the diagnostics designed to confirm proper installation of the DCT5100.
They include checking error states, signal integrity, and provisions to identify the DCT5100 on
the network and verify communications with the headend. The diagnostic information is
displayed on the front-panel LEDs and the On-Screen Display (OSD).
For diagnostics provided in this section:
All indicators are in decimal notation unless otherwise noted.
All signal-level and quality indicators are based on a 1% to 100% scale, unless otherwise
noted.
All sample displays are illustrative; actual data may differ from the examples.

diagnostics. The Heritage mode and the Enhanced mode are the two modes of entry for

commonly used with the DCT 1000, DCT 1200, and DCT2000 models. The Enhanced mode uses
the front-panel keys and supports an on/off state-independent entry.
