RV50 Standby to Idle Time



I am interested in the time it takes for the RV50 modem to switch from standby mode to the Idle mode and re-establish a network connection so that a UDP packet can be sent from the modem to a remote server.

(The RV50 is to be used in a remote telemetry application where to conserve power the modem is mainly in the Standby mode).

Does anyone have an experience or documents on the timing for the RV50 (or other) modem to come out of standby mode and be active.
