[edit] Origin

1MC term or circuit is not only used by USN. I'm onboard a Modified Lupo-class frigate and we also use that term, is it a NATO standard for internal comms circuits? we got here 1MC, 5MC (engine rooms) and 27MC (ASW). -- Evogol^Talk 20:55, 20 May 2006 (UTC)

The USN was probably the origin. After all, many navies acquired trained under the RN and USN, which share similar nomenclature. —Joseph/N328KF (Talk) 03:59, 28 May 2006 (UTC)

[edit] Phased Out

The IVCS system hasn't been phasing out the 1MC. The 1MC is still used to address the crew, while the IVCS is just a system for dialing direct to other spaces, much like telephones, although it does have a "conference" like capability called a net. If IVCS replaced anything, it's the old "growler" system. I'm on the USS Chancellorsville (CG-62) and this is how we and other ships on our waterfront are set up. --JimDanger 14:34, 18 June 2006 (UTC)
