Before you connect a port, read its label carefully. A wrong connection can cause damages to the
interface module and even the device.
Step1 Identify the to-be-connected port on the MIM-4BSE.
Step2 Identify the type of the ISDN line provided by your telecommunications service provider.
Step3 Connect the cable.
