Testing TCP Ports with Telnet

I know when it comes to testing TCP ports that are open, Administrators use Telnet.
However most of the time Telnet service is not enabled on local PCs as well as on remote Servers.
It is a tedious process each time you need to test a port , you will have to enable Telnet service on local and Remote computers.

Any alternate tools ?

Thanks

I know if you have Telnet service enabled on the client and on the server you can test the TCP port, but most of the time for security reason Telnet service is disabled on windows computers
I wonder if SSH can be installed and enabled on the client and can be used without having to install it on the server ? which I doubt it

I am looking for a tool that tests from the client to the server whether a certain port is open, if the tool scans all the ports open on a certain server that's fine too
