OLTS-85 Configuring Local versus Remote
Knowledge Base - FAQ
How do you configure a Viavi OLTS-85 to be a Remote unit or a Local unit?
OLTS-85 units are typically sold in pairs for the Tier 1 fiber testing. Both units ship configured as Local units so the first thing you will want to do is change one of the units to be the Remote unit. This is done be pressing the MENU button (middle button under the display). Press MORE and then press DEVICE. The DEVICE selection allows you to choose between Local and Remote.
