Hi to all,
I am trying to test the 1803 router with g.shdsl port with his conectivity to ATM network, but i am recieving couples of problems that i dont know how to fix it.

1) When i am trying to config under pvc 0/87 "cbr" i am recieving the next text:

C1803(config-if-atm-vc)#cbr 4350
Insufficient bandwidth on interface or invalid PCR. Available bandwidth = 0

2) all the time i see the error on the screen:

*Feb 15 10:10:57.604: %DSLSAR-1-DOWNGRADEDBW: PCR and SCR for VCD 1 (8/35) has been reduced to 0k 0k due to insufficient upstream bandwidth

What should i do to fix this and make my router to work with CBR.

There is the full configuration of him:

Pls Advice

What do you think is your upstream line rate for this DSL service? I see you've already allocated 2495K to another PVC.

Can you paste a copy of 'sh atm pvc'

Thanks
 
its only an example :)
Of course its not exist when i am tying to configure the CBR

Ok. I suspect you've just oversubscribed your upstream line rate. Most DSL providers don't offer great upstream rates.
