By default, the option for negotiation towards the Telnet client is enabled, and
Reverse Telnet will expire in 600 seconds. Reverse Telnet transparently transmits all
data. The interface use the default listen port number.
Reverse Telnet timeout ensures that if no data is transmitted during a specified
time, the established Reverse Telnet will disconnect automatically. By default, no
timeout is configured for the Reverse Telnet, that is, as long as the Reverse Telnet is
connected, even if there is no data being transmitted, the Reverse Telnet will not
be disconnected.
The Reverse Telnet can be disconnected in interface view.
The command must be used to disable modem calling-in and
undo modem
calling-out before the Reverse Telnet timeout of the configuration interface is

On the 3Com Router series, the maximum number of Reverse Telnet connections
is related to the interface card and the maximum number of tasks supported by
the router.
