SSA Loop Rules

• Roughly:

  • A loop starts always from A1 plug and finishes with A2 or from B1 to come back by the B2 plug.
  • Never mix an ‘A’ plug (A1,A2) with ‘B’ plugs (B1,B2) in the same loop
  • Never link together two loops (even in the case that bypass cards close a loop when one the server is down)
