In the U.K., the standard connector for ISDN equipment is the eight-pin RJ jack. Patch cables
have eight-pole plugs at both ends. The same pinout applies to both ends of an ISDN cable,
which is the practice of the data world. This means that a flat untwisted cable with an RJ
modular plug at both ends will have the locking tab of the plug on one end, "up;" and on the
other end, "down," as shown in
A cord of up to 10 meters connects the ISDN BRI RJ45 wall jack to the desktop TE.
