If the D channel is not working it will be red - ensure you have the right settings for the switch type (5ESS, DMS, whatever). ... if it is orange I think it's in loop back.

Does anyone know if lamp patterns on a HiperDSP have error code meanings?
I have a situation where a HiperDSP (2.1.9) connected to a PRI has the lpbk/d-alm lamp on red. The telco (NTT) says there is no problem with the PRI and their tests indicate the CPE is not powered up. The NTT DSU shows no alarms.
I have replaced the card with another one, and see the same problem. Moved it to another slot in the chassis. Same problem.
If I power-cycle the card, I see the following after the boot process:
rn/fl orange lpbk/d-alm red activity lamps (from the top) 3,4,7,8 red
Then after a few seconds, rn/fl and car go to green, the modem activity lamps go out, and lpbk/d-alm stays red. The previous card exihibited the same behavior, and reflashing has no effect on this.
Is this pattern of lights an error code or coincidence?
This would all seem to indicate the PRI, but the telco says it's not. Any thoughts?
TIA,
