COMSPHERE 3800 Series Modems – Model 3830
The Model 3830 provides the 2-wire leased-line signals on the same
leads used for Tip and Ring when in Dial mode. To connect the modem
to a standard JM8 leased-line jack, a conversion cable (125-0054-1531)
must be used. Note that for 2-wire leased-line operation, the yellow and
black leads are not used.
The wiring of this cable is illustrated in Figure C-1.
