We have a ring down system at our HQ that connects to channel banks / FXS cards at the far end. The FXS are analog phone lines like the phone company delivers to your home. Several far end users are taking the FXS output and connecting it into a Cisco Routers FXO port so they can extend the circuit. Works OK but there is a disconnect supervision issue. We have an opportunity to add a Supervisory disconnect tone on a new system we are purchasing but I am not sure what the frequency and cadence should be for most applications.

Does anyone know of a standard?

Does the disconnect sup tone only work with an H.323 gateway?

If you can make the FXS-FXO ground start. That may solve your disconnect supervision problem.
