connected to another Strata system (or any system in compliance with BTNR181, section 4)
the recall feature inherent in AC15 'type C' signalling which allows anti-tromboning will be

Insert the PACU (component side facing right) into the appropriate Expansion cabinet
slot and apply firm, even pressure to ensure proper mating of the connectors.
Each PACU decreases the maximum system exchange lines by four.
After installing, gently pull the PACU outward. If the connectors are properly mated, a
slight resistance is felt.
