I am trying to make an ADSL Internet connection with 2800 router. ADSL line is working with another brand ADSL router (ADSL_G.dmt modulation, 49 downstream attenuation, 31 attenuation, fast path mode). However when I try to connect 2800 router this line it fails: Debug atm error and events show that, the router announces line quality as bad. How could I change the SNR margins? Also I could not see the controller dsl 0/1/0 on the router configurations.
The configuration is quite simple:
interface ATM0/1/0
no ip address
no ip redirects
no ip proxy-arp
no ip route-cache cef
no ip mroute-cache
load-interval 30
no atm ilmi-keepalive
dsl operating-mode auto
pvc 8/35
pppoe-client dial-pool-number 1
!
end
