## I have two devices pumping out X21 using a leased line in between. Can I replace the leased line with an ISDN PRI somehow doing some sort of X21 to ISDN PRI conversion. Is there an example of this anywhere ?

I want the ISDN PRI to be DDR.

Has anyone done something similar with

example configs if this is possible ?

The best that you could do is to get an

ISDN TA (this is BRI, not PRI) with an

X.21 interface. The serial interface

would then be configured for DDR.
