The RJ-45 connector on the Model IM 1/F twisted pair interface is
pre-wired according to the signal/pin relationships shown in Figure 5
below.
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) 975-1007. Additional assistance at
our website, http://www.patton.com, or at our e-mail address at sup-
