Tom,

I have verified there is an allow in place at the other side.

The only ways your LDM would use a port number other than 388 would be if
1) you explicitly specified a different port number to the LDM configure(1)
script; or 2) your REQUEST entry specified another port.

You can verify that your system can reach the upstream system with either
telnet(1) or ncat(1):

    telnet <upstream host> 388
    ncat <upstream host> 388

Control-C will terminate any connection.

They both do the same thing: try to create a TCP connection to <upstream
host> using port 388. If they fail, then either the upstream host isn't
running an LDM that listens on port 388 or something is blocking you. In
the later case, you should tell your netadmin.

Try the telnet/ncat test.
