gentilmente qualcuno potrebbe chiarirmi questa situazione?
Da qualche anno uso il mio 837 su una normale linea interleaved Alice 7Mbit e fin quì tutto ok.
La settimana scorsa ho domandato in TI il passaggio al profilo fast e probabilmente mi è stato attivato perchè il router non riesce più ad allinearsi correttamente, cioè rimane connesso saltuariamente qualche minuto e poi l'atm0 va in down.
