Hello i am having layer 1 problems in placing an 836 router for ADSL over ISDN, the story so far ; the LEDs of the ATM interface (Rx,Tx and CD) keep going on and off(constantly, yes i know, not good), doing a #show ip int brief, obviously shows that both ATM0 and ATM0.1 are in down state (they are not admin. down), i have followed Cisco4s troubleshooting 'steps' from their website, from checking if DSL port is plugged in correctly, checking correct powersupply, placing dsl operating-mode in auto to checking if the circuit is tested (i have placed an Alcatel SpeedTouch and it works), now i am running out of options.
a curious thing is when i issue a #debug atm event, i get the usual readout for activation state changes, then : "LOCAL:Max noise margin for power cutoff 31" followed by a long list of bad news, "modem state 0x8", on other adsl capable cisco routers(not over ISDN) i usually have dsl power-cutback set at 0 at the interface ATM 0, whereas with this router, i dont have this option. i tried to hunt for any intel relating to what does this power-cutback 'feature' actually do and if its related to this layer 1 problem and found nothing, maby i am taking the wrong approach to figuering what is wrong/missing, maby i should leave that Alcatel modem running and put that cisco router back in the box thing is i dont know where to look anymore, help? ;) sample of my config: ! vpdn enable ! vpdn-group pppoe request-dialin protocol pppoe ! interface Ethernet0 ip address 192.168.0.210 255.255.255.0 ip nat inside ip tcp adjust-mss 1452 ! interface ATM0 no ip address no atm ilmi-keepalive dsl operating-mode auto ! ! interface ATM0.1 point-to-point pvc 0/35 pppoe-client dial-pool-number 1 ! ! interface Dialer1 mtu 1492 ip address negotiated ip nat outside encapsulation ppp dialer pool 1 no cdp enable ppp chap hostname xxx ppp chap password 7 xxx ppp pap sent-username xxx password 7 xxx ! ip nat inside source list 1 interface Dialer1 overload ip classless ip route 0.0.0.0 0.0.0.0 Dialer1 ! access-list 1 permit 192.168.0.0 0.0.0.255 !
