30
CONNECTING TO A TELEPHONE LINE EQUIPPED WITH AN RJ11 SOCKET
While testing telephone lines, if there is no necessity in a parallel connection of end user
devices, a cable fitted with an RJ11 socket is cable-connected to the main unit ( fig.1, 3 ). The
connection scheme is shown in fig.26, 3C.

Ways of
parallel-connecting to telephone lines, when end user devices (telephones or
facsimile machines) need to be in operation, are shown in fig.26, 3D and 3E.
The 3D option is used when the telephone line is fitted with a singular RJ11 socket. An RJ11
splitter ( fig.1, 14 ) and cable ( fig.1, 3 ) are to be used in this case, for connecting the main unit.
The 3E option is used, when telephone line is fitted with a double RJ11 socket. In this case,
the Main Unit is connected to one of the two socket inlets through a special cable ( fig.1, 3 ), while
a telephone or facsimile machine is connected to the other through a standard cable.
5.4. CONNECTING TO LOW CURRENT MULTI-CORE CABLES NOT FITTED WITH
CONNECTORS
For testing multiwire cables not equipped with either sockets or plugs, a special adapter ( fig.1,
16 ) is used. The connection scheme is shown in fig.27.
