Note: DX trunks must be balanced correctly. If the loop is <2.5 K
3
/4, far-end balancing is standard.
If the loop is >2.5 K
3
/4, far end balancing requires standard plus 2.5 K
3
/4. To connect PBX to PBX,
switches should be arranged for loops to be >2.5 K
3
/4 at one end and <2.5 K
3
/4 at the other. Apply
similar treatment when connecting to Pulse QPJ69 trunks.
