Can anyone point me to a listing of the various error codes relative to Sprint's CDMA-based "Sprint Direct Connect"?

Where we are we are getting horrible Sprint DC service, the error codes we have received so far are 310, 320, 800, 900.

I don't know if those codes are specific to Sprint DC, or if they are generic to CDMA, but those are the ones that show in the display the many, many times Sprint DC fails to establish DC connections, and thus far these Sprint DC "denial of service" incidents are the only times we see those codes.

Thanks in advance to anyone who can shed light on these Sprint CDMA DC error codes.
