router with atm interface/ dsl

Hi everybody

When we say a router has a DSL interface, does it mean just regular ATM interface?

Let say we have Router at site S1 and we want to connect it to HQ via internet.

We decided we will use DSL to connect S1 to internet. So in short:

S1-R1--DSL-------ISP--Internet-----ISP---DSL---HQ

Can we just use a Router with  ATM interface and configure it with DSL appropriate DSL commands to connect it isp

Does ATM interface on a router use RJ-11 connector?

thanks and have a great weekend.

Hi Sarah,

DSL use ATM technology. You have to get a DSL WIC for your router and not ATM, but the config applies to an ATM interface.  And yes, the interface usually is RJ-11

Re: router with atm interface/ dsl

hi Sarah,

It should look something like ATM0 or ATM0/0/0 depending on the model you use. Below is a config on a cisco 837 router. So as you can see you create the PVC and off you go.

interface ATM0

no ip address

no atm ilmi-keepalive

dsl operating-mode itu-dmt

!

interface ATM0.3 point-to-point

  description Internet Network

pvc 8/35

  encapsulation aal5snap

  pppoe-client dial-pool-number 3

To troubleshoot the dsl and to check the SNR, attennuation and all here is the command sh dsl interface 0

. This command will show the sync speed and a lot more detail.

If you want to see the ATM pvc details then  " sh atm vc detail" should show whether the pvc is up or not etc

HI Kishore

I was thinking more about connector type.  What kind of connector atm interface on router  use?  For example  dlc wic use  rj 11.

Thanks
