arrester at the input end of the interface cable for better lightning protection.
Before you connect a port, read its label carefully; a wrong connection can cause
damages to the interface card and even the device.
Step 1: Identify the to-be-connected port on the MIM-4BSE.
Step 2: Identify the type of the ISDN line provided by your telecommunications
