Pin	Designation	Direction	Function
1	RD (R)	Input	Receive data (ring)
2	RD (T)	Input	Receive data (tip)

Balanced-to-Unbalanced Adapter Cable

When IPmux-11 is ordered with unbalanced E1 interface, it is necessary to convert the RJ-45 connector to the standard pair of BNC female connectors used by unbalanced E1 interfaces. For that purpose, RAD offers a 150-mm long adapter cable, CBL-RJ45/2BNC/E1/X, wired in accordance with Figure A-1.
