what interface connent to your LAN? i Notice you configure 1 vlan with ip address 172.16.0.1 255.255.25.0 it look like you need asign it to the LAN interface.

hi,
could you run some debugs and do a shutdown/no shutdown on the ATM interface?
kindly post debug output.
debug ppp authentication
debug ppp negotiation

- To lloyd whitton : The port is L2, only can configure IP on Vlan 1.
- To johnlloyd_13 : I have shut / no shut the ATM interface, and do the debug as you give, but no thing display.

hi,
issue the 'terminal monitor' command if you're connected remotely and redo the debug.
could you also check if you're getting a dial tone on this line?

Hi,
- I'm using console cable connect directly to the router, but no thing display.
- The line is working fine because before this line connect to the Dlink router, now we want to change to cisco 877 router.

hi,
contact with your telco/service provider if their DSLAM supports this type of router.

Hi,
I have checked with my ISP SingTel, and they say it can support DSLAM for cisco router 877.
My configuration is missing any command?

hi,
there are some lines i would suggest to be added, but we'll need to make sure your layer 1 is working properly
you sure you've connected the RJ11 to the ADSL/POTS port? please post your 'show interface atm0' output?
if you connect a phone, do you get a dial tone? is there a microfilter in between?
