How to do protocol translation between two VTY lines

Dear All,

I have POS device connecting over ISDN lines using V120 into Cisco 2911 with PRI ISDN interface. I managed to connect it to VTY line on the router with global command VTY-Async. Hence when i issue "show users" i can see VTY line used by particular ISDN B channel. On the other hand on inside network i have an application using telnet to connect to router with aim to connect to POS device.

Now my problem is to connect those two VTY lines to each others so that LAN application using telnet protocol can reach POS terminal over ISDN.

Let us say this is just for you to inform you what i am working on. For more information i will provide you with your requests. I hope this is sufficient information to work on the concept. I m looking forward to any ideas.


Best Regards!
