To The guy wants to add a 1030c.

He dosen't need a Valcom 2000 control interface.

He needs to take the audio from the page port and and use a 24 transformer to run the 1030c.

The viking stuff is just that. This is another separate crkt of an existing page unit.

Now, Ive got a guy who hid an existing relay key on a 2565 set on a 551c.

Now that's trouble.
