See Figure 1-2 "TS Adapter in the System" for details of
modem connection. A modem is connected to the RS232
interface of the TS adapter using the enclosed RS232
cable. In the modem description, this cable is used for
connecting the modem to a PC. If this modem cable does
not have a 9-pin SUB-D socket connector on the TS
adapter side, the relevant adapter must be used
(Figure 1-5).
