Why can't I ping to port 123 when NTP daemon is up and running?

I have a question related to NTP service. Ntpd service is up and running on my machine named "ntpserver" configured with IP 192.168.105.80. Remotely (from another computer) I want to check the NTP service whether it is up and running by using command `telnet 192.168.105.80 123` and I get the warning message about the connection refuse. Why in this case I cannot telnet to ntpserver using port 123?
