Iznimno neobično.
FEC greške su one koje su već ispravljene, nisu toliko bitne ali je poželjno da ih ima čim manje.
Dok su ES greške one ozbiljne, to je sekunda kada usluga nije radila, paket nije poslan/primljen.
Kako ih ti imaš iznimno puno na tvojoj parici koja je inače veoma blizu centrale nešto ozbiljno ne valja na parici i vrlo vjerojatno na nekom mjestu imaš kratki spoj s drugom paricom.
Iskon bi trebao proslijediti HT-u "kvar na infrastrukturi" kako bi ti HT zamjenio paricu ili sanirao ovu.
Za primjer je moja puno gora i udaljenija parica pa svejedno ima manje grešaka;

Inače krkani u tehničkoj iako na nekoliko mojih zahtjeva da promijene profil na dslamu u Target margine 6dB, Annex M 21M/5M da imam DL 21500 (punih 20Mbps) su "napravili" ali nakon resinka opet imam 19.15Mbps.
