Figure 5. Model IM 1/F Twisted Pair Interface Signal/Pin Relationship
Important: Connection of the Patton G.703 IM to a CSU DTE requires a crossover twisted pair cable. Connection of the G.703 IM to a PCM network requires a straight through twisted pair cable.
If you need more assistance with cable selection and preparation, contact Patton Technical Support at (301)
