Managing Telnet Sessions
Suspending Telnet Sessions:
When you are connected to an external modem, the direct Telnet session must be terminated before the line can accept incoming calls. If you do not terminate the session, it will be indicated in the output of the show users command and will return a modem state of ready if the line is still in use. If the line is no longer in use, the output of the show line value command will return a state of idle. Terminating the Telnet session requires first suspending it, then disconnecting it.
