dsl router

Hi all, can anyone tell me what the command dsl operating mode auto does ?



Re: dsl router

Hello Carl,

This command gets the router to auto-detect the type of DTM your ISP is using. Comes in handy of you are not sure.

Router#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#interface atm 0

Router(config-if)#dsl operating-mode auto


Router#write memory

Hope this helps.

Re: dsl router

It has been a while but if memory serves the answer is yes. Some of the router gurus may chine in later today to either confirm or correct that answer.

Hope this helps
