Note: DX trunks must be balanced correctly. If the loop is <2.5 K ¾, far-end balancing is standard. If the loop is >2.5 K ¾, far end balancing requires standard plus 2.5 K ¾. To connect PBX to PBX, switches should be arranged for loops to be >2.5 K ¾ at one end and <2.5 K ¾ at the other. Apply similar treatment when connecting to Pulse QPJ69 trunks.
