Enable PPP on 
VTY Lines for 
Asynchronous 
Access over ISDN
You can configure a router to support asynchronous access over ISDN 
by globally enabling PPP on VTY lines. PPP is typically enabled on 
synchronous or asynchronous serial interfaces; however, the Cisco 
IOS software permits you to configure PPP on VTY lines. This con-
figures the VTY line to support asynchronous access over ISDN from 
an ISDN terminal to a VTY session on the router.
In global configuration mode, enable asynchronous protocol features 
on all the router's VTY lines:
vty-async
This task enables PPP on VTY lines on a global basis on the router. To 
configure PPP on a per-VTY basis, use th
translate
command.
