Trochu jsem se vrtal v diagostice modemu a u upstream noise margin mi to pise: relative capacity occupation: 0% noise margin upstream: 28 db output power downstream: 19 db attenuation upstream: 17 db tone 0- 31: 00000000000000000000000000000000 tone 32- 63: 00000000000000000000000000000000 tone 64- 95: 00000000000000000000000000000000 tone 96-127: 00000000000000000000000000000000 tone 128-159: 00000000000000000000000000000000 tone 160-191: 00000000000000000000000000000000 tone 192-223: 00000000000000000000000000000000 tone 224-255: 00000000000000000000000000000000 u downstream noise margin mi to pise: relative capacity occupation: 0% noise margin downstream: 24 db output power upstream: 12 db attenuation downstream: 32 db tone 0- 31: 00000000000000000000000000000000 tone 32- 63: 00000000000000000000000000000002 tone 64- 95: 23445555667777888888888888888888 tone 96-127: 08888887777777777666666666666666 tone 128-159: 66666666665555555655356666666666 tone 160-191: 66666666666655555556566666666666 tone 192-223: 66666666666666666666666666666666 tone 224-255: 65555555555555555555553555544332 Docela mne zarazi ze u upstreamu jsou u tone same nuly a u downtreamu ruzna cisla. Mam zapojeny pouze jeden telefon a ten je az za splitterem. V telefonu slysim slabe praskani. Jsou ty hodnoty v normalu? Muze to odkazovat na utlum signalu?
