The values in the tables above are calculated based on the following assumptions.
• The number of 50DUs that can be connected is based on the assumption that the ATUC-M is used.
• The number of IUs that can be connected is based on the assumption that ATUC-M, TALK LED, FLOOR LED, 8-Ω speaker units, 32-Ω
impedance headphones, and GPO terminals with LED x 4 (7 mA each) are being used.
• Given that Cat5e or higher cables are used. (Shielded cables with conductor size of 24AWG or higher in diameter)
• 1-port daisy-chain connection/1 ring connection: Given that one of the DU CHAIN A/B terminals is connected in a 50DU/IU daisy chain
or that the A-B terminal is connected in a ring.
• 2-port daisy-chain connection: Given that the same number of 50DUs/IUs are daisy-chained to the DU CHAIN A/B terminals.
• 4-port daisy-chain connection: Given that the same number of 50DUs/IUs are daisy-chained to both the DU CHAIN A/B terminals and
the same number of DUs/IUs are daisy-chained to the DU CHAIN C/D terminals.
• 2-ring connections: Given that one ring connection is used for the DU CHAIN A-B terminals and for the DU CHAIN C-D terminals.
• "Number of 50DUa + VUs connected" is when using NFC.
