You need to configure mode under controller vdsl0 first.

Note 887V is VDSL2 only and does not supports ADSL.

[j.medinapadilla]

yes i did it but it just have operating mode auto and for vdsl2 doesn't sopport any command

[kmccourt]

I believe VDSL is configured under Ethernet0 in this model and there is no ATM interface.

See http://www.cisco.com/en/US/docs/routers/access/800/860-880-890/software/configuration/guide/routconf.html#wp1163169

That is correct, no ATM and no ADSL on 877V-xx

[j.medinapadilla]

Ok i undertand that but why does the router have a VDSL o POTS PORT ?

VDSL2 uses PTM (packet transfer mode), not ATM. That's how it works.
I have an 867VAE working here, VDSL2 over POTS. No ATM involved.

Also see http://www.cisco.com/en/US/prod/collateral/routers/ps380/qa_c67_458826.html

Q. Does the Cisco 887V platform also support ADSL, ADSL2, and ADSL2+?
A. The Cisco 887V platform supports only VDSL2 technology.

Q. Does the Cisco 887V platform support both ATM and Ethernet Packet Transport Mode (PTM)?
A. The platform supports only PTM.

you need to connect the cable there.

for VDSL tech , you don´t have an ATM interface. you need to configure it via ethernet int over ppoe. It is quite tricky I know it. If you have any question I can share a cisco config-

thanks

Please do share the configuariton, i believe the copper cable from ISP will conenct to VDSLoPots and we will configure ethernet with "pppoe-client dial-pool-number 1" and then configure the respective dialer interface?

But would it get all the parameters like PVC/VCI numbers automatically?

thanks.

Again: there is not ATM, and no VPI/VCI in VDSL2.

[jesus dedios]

for VDSL PCV/VCI  and ATM are not required,

attached, is cisco config.
