Testing the Orderwire Call

Testing the Orderwire Call

This section describes how to check the orderwire phone communication between a certain station and any other station to ensure that the orderwire phones between the two stations work normally.


  • The fiber connection of each station is fine.
  • The orderwire phone must have been installed at each station and configured by using the U2000.
  • Test personnel must be accessible on site when the orderwire phone is tested.
  • The current line must not be occupied by a conference call.

Tools, Equipment and Materials
