leased line conection using X.21 and V.35 question

[lunarsystems]

Hi there,

We have one site in Scotland, where 2800 router with X.21 NTU is connected throught a leased line to a site in Bangladesh that also uses 2800 router, but with V.35 NTU. The loopback test is working fine, but we cannot establish a proper connection.

My question is: Is it possible to have a connection using different NTU interfaces, in this case X.21 on one end and V.35 on another?

Thanks

Yes, it is possible. Please detail the tests made and show interface taken on both routers.
