PSTN AC Termination, Disconnect Tone and Cadence

I am in the San Jose, California area.
SBC (now ATT) provides us POTS on our single analog line.

I need the following information from my "local PSTN provider"
to configure some FXO settings:

PSTN AC Termination
PSTN Disconnect Tone
PSTN Disconnect Tone Cadence

I called the ATT service number on my phone bill.
The service person was not able to help me at all.

Can you advice me?
Are there other ways to get this information?
