I was connecting an 886 VA-J Cisco router do a DSL line in Germany the other day and I learnt some useful stuff:
- if you do not use their Digitalisierungsbox as the modem, you need to get a TAE>RJ11 adapter. TAE end goes to the DSL cube with the cables that the technician installs in your wall, and the RJ11 goes to the VDSL port on your router.
- it turned out that the syntax for dialer settings is a bit funny. So when they send you a piece of paper with some numbers (Anschlusskennung, T-online-nummer, Mitbenutzernummer, Kennwort), you are actually supposed to use them as follows:
So if Anschlusskennung is 11111111, Tonlinenummer is 222222222222 and Mitbenutzernummer is 0001, Kennwort is 3333333, your chap hostname should be:
And the whole config is as follows
interface ATM0 no ip address load-interval 60 no atm ilmi-keepalive ! interface ATM0.7 point-to-point pvc 1/32 bridge-dot1q encap 7 pppoe-client dial-pool-number 1
interface Dialer1 ip address negotiated no ip directed-broadcast encapsulation ppp dialer pool 1 dialer-group 1 ppp authentication chap callin ppp chap hostname email@example.com ppp chap password 333333
If you don’t get an ip address, turn the PPP debug on (debug PPP packet, debug PPP events) and put your thinking cap on, too 🙂
