cable as an E1 cross-over!
+==== Switching between TE/NT mode
+
+The icE1usb is shipped in TE configuration. Using a 1:1 patch cable, it can be connected to another device in NT mode. +
+If you want to connect to a PBX, BTS, etc., you'll need to use an E1 cross-over cable or switch to NT mode.
+
+To change the mode, unscrew the 2 PH0 screws on the side with the 2 RJ45 jacks. You'll also need to unscrew the nut on the SMA jack on the other side.
+After that, the cover plate and rubber gasket around the 2 RJ45 jacks can be removed. The PCB can be slid out of the case.
