Ok so since -3dB is 1/2 power we should be expecting a reading of 7422 in ztmonitor if it's a linear reading of the signal. > If the milliwatt is arriving at the demarc at the nominal -2 to -3dbm > and getting into the asterisk to be measured at 8dBm (+8dbm0), I'd say > something is grossly mal-adjusted. You're seeing 8db of gain! No, he was saying he had to set his rxgain to 8 in order to get a level of 14844 (0dBm) in ztmonitor. -A. _______________________________________________ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
