Appendix B

D i a g n o s t i c s

This section describes the diagnostics designed to confirm proper installation of the DCT 2000. The diagnostics include checking error states and signal integrity, as well as provisions to identify the DCT 2000 on the network and to verify communications with the headend. The diagnostic information is displayed on the front-panel LEDs and the On-Screen-Display.

For diagnostics provided in this appendix:

§All indicators are in decimal notation unless otherwise noted.

§All signal-level and quality indicators are based on a 0 to 100% scale, unless otherwise noted.

§All screens self-refresh at a minimum rate of once every five seconds.

§All sample displays are illustrative; actual data will differ from the examples.
