• Redirection terminal services: You can run the Telnet client program on a PC to log on to
the router through a specified interface. Then, connect with the serial interface devices
that are connected with the asynchronous interface of the router, as shown in Figure 9-2.
The typical application is to connect the 8/16-port asynchronous interface of the router
with multiple devices for remote configuration and maintenance.

OQ NOTE
Only devices that provide an asynchronous interface support the Telnet redirection service.
• Interruption of Telnet services: You can use two types of shortcut keys to interrupt a
Telnet connection: Ctrl_] and Ctrl_K.
As shown in Figure 9-2, Router A logs on to Router B through Telnet, and Router B logs
on to Router C through Telnet. Thus, a cascade network is formed. In this case, Router A
is the client of Router B, and Router B is the client of Router C. Figure 9-3 illustrates the
usage of the two types of shortcut keys.
