test connection if ICMP is disabled

Telnet will make a tcp connection to a remote ip/port to test connectivity. If it times out, it's not reaching the host (maybe the firewall is blocking it). If connection is refused, it's reaching the host, but either the service is not listening on that port, or it's locked.

If you can do better, submit your command here.

What others think

This is useful if you are certain the port is listening (to test connectivity); or to test whether the port is listening (test service). It's also very useful to test connectivity when ICMP is blocked at the firewall.
