• The East plug-in will be transmitting on the primary ring, and receiving on
the secondary ring. The West RAC will be receiving on the primary ring and
transmitting on the secondary ring.
• The plug-in assigned as east will retain any existing connections, and circuit
assignments for the west will automatically be assigned to match the east.
(Any prior circuit connections for the west will be dropped - view
'Consequences' for on-screen advice).
• The slot number in which the east plug-in is installed will be the Ring ID
number (slot number)

view the Protection Selection window. Only valid partners are shown.
