求助!2600无法拨号入网?

wmmiss2002

朋友公司使用cisco2600,加载了ADSL拨号模块,前段期间突然出现无法拨号入网,PING不通外网.不知为何原因,是否跟当地电信局局端ATM端口有冲突呢?可为何以前正常呢?已经单接ADSL猫及宽带路由器测试过,ADSL线路无问题.求救....\r\ninterface ATM0/0\r\n no ip address\r\n atm vc-per-vp 256\r\n no atm ilmi-keepalive\r\n atm voice aal2 aggregate-svc upspeed-number 0\r\n dsl operating-mode auto\r\n no fair-queue\r\n!\r\ninterface ATM0/0.1 point-to-point\r\n pvc 0/100 \r\n pppoe-client dial-pool-number 1\r\n !\r\n!\r\ninterface Ethernet0/0\r\n ip address 192.168.10.1 255.255.255.0\r\n ip nat inside\r\n ip tcp adjust-mss 1452\r\n full-duplex\r\n no cdp enable\r\n!\r\ninterface Dialer1\r\n ip address negotiated\r\n ip mtu 1492\r\n ip nat outside\r\n encapsulation ppp\r\n dialer pool 1\r\n dialer-group 1\r\n no cdp enable\r\n ppp authentication pap callin\r\n ppp pap sent-username ********* password ************
