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
