V.24 CABLE BETWEEN SOPHO-LAM AND MODEM
When the SOPHO-LAM is used in a convertor configuration it must operate in the DTE mode.
In this mode the test circuits CT141 and CT142 are used to provide full DTE functionality. So,
a few V.24 circuits are not used according to the CCITT V.24 recommendations. Therefore a
special cable has to be used between the SOPHO-LAM and the modem. Figure
