Multi-CCU caters for situations where more than 240 contribution units are required. Multi-CCU
systems are controlled from a separate, dedicated PC running OS.2 version 3.00 Warp operating
system, the Multi-CCU software (LBB 3586) and equipped with the LBB 3511/00 Network/Multi-
CCU card. All Multi-CCU units and the LBB 3511/00 are interconnected via a closed loop.
