* The maximum cabling distance from the PBX is the same even when the KX-DT300/KX-T7600 series DPT
is the master DPT on the Digital XDP connection.
Notice
• If the cabling distance exceeds the maximum cabling distance above, satisfactory performance of each
terminal cannot be guaranteed.
• The connected terminals will operate over the maximum cabling distance under optimum conditions.
However, the maximum cabling distance of SLTs connected to ports No. 9–24 of the ECSLC24 card
may be shorter than that of SLTs connected to the ESLC16 card.
