The network administor must have physical access to the device to establish a console connection whereas TELNET access can be established form a remote location. However telnet access depend upon a router with network access's, whereas a console connection can be used to access the router regardless of the router's configuration.

If you connect to the router via the console port then you are physically making a connection with a physical cable to the router. This implies you have to be close to the router itself.
