Router Cisco 878 problema con configurazione adsl SHDSL 4Mb

[antoniotst]

Buongiorno a tutti,
sono nuovo del forum, vorrei sottoporVi una problematica che ho incontrato nella configurazione del Router Cisco 871 con una SHDSL 4mb fornita dalla TWT. Loro mi hanno dato una configurazione base che mi dà infiniti errori durante il caricamento ed è la seguente:

Ho modificato tale configurazione con quella che segue ed adesso non ho più messaggi d'errore, il router ha abilitato il dhcp ma non si connette....

Ciao,
tu hai usato il pvc 8/35, nella loro configurazione usavano il 10/35.

Correggi e poi fammi sapere se funziona o no.

Si ho modificato il pvc ma non va comunque. Il led CD rimane sempre spento....

Se fai un sh ip int brief come sono le interfacce?

[anubisg1]

tu hai un ip statico? li risulta che dovresti avere un ip

1.1.1.2/30

non mi sembra credibile.. se ti devi collegare solo con "username/password" e un ip dinamico. questa è la mia config:

spero possa aiutare!

Penso che l'IP non è quello configurato ma uno fittizio.
La maggior parte delle HDSL sono con IP statico e non autenticato.

se provi a mettere soltanto l'annex b? anche se visto che non sale il cd è piu probabile un problema di linea che di conf.
