To what are you connecting?

001917: Aug  8 11:11:15.980 EDT: htsp_process_event: [0/2/3, FXOLS_WAIT_DIAL_TONE, E_DSP_SIG_1100]fxols_power_denial_proc

that indicates router cannot detect loop current.

Thanks Paolo, Whether the problem with router or with carrier end?. All 8 FXOs are connect to carrier. We are receiving incoming calls via the same FXOs but out bound calls are dropping with cause code 34 in all the Fxos. Rebooted the router but no luck.
