pseudowire configuration in ASR1001-X to extend DS3 links

[guigonza]

Hi ...

We have some sites connected through Cisco ASR1001-X routers.  I've attached the schema and "show inventory" of two routers to show the modules and models.

We configured "pseudowire" Ethernet over MPLS to extend some VLANs.  This configuration works fine.

We would like to configure something like that using DS3 interfaces to extend the connection of T3 serial link between two Nortel Passports installed in Site A and C.  But, we could not make this configuration. 

I would like to know what is the problem:

- are these DS3 cards compatible with pseudowire (cem) ?

- is there any way to do that using this cards ?

Thanks in advance ...

Guillermo.

excuse me, the attachment.

I think your SPAs do "IP over E3/T3":

For the other way around (circuit emulation - "E3/T3 over IP") you would need something like this:

Thanks Lulian ...

I know the SPAs do "IP over E3/T3",  but we need DS3 over IP.

The point is when we tried to configure circuit emulation, we are not sure about the compatibility of this model of card with this feature.  The card we have is SPA-2XT3/E3 2-port T3/E3 V2 Serial Shared Port Adapter.   All the documentation we got about CEM is related to ATM on channelized cards, but I didn't find any information about this model.

Do you know any example or any case about this type of card with CEM ?

Thanks for your help.
