4.1.3 Interface C (8-pin RJ45 connector)
The TANGO55/56 modems provide this interface (RJ45) for serial and audio
connection.
You can use a RJ45 serial cable to connect the modem's RJ45 connector (Interface
C) to external controller/computer (without HW handshake). If TANGO55/56
modems have been connected through interface B, interface C is automatically
deactivated (Rx, Tx). In this case, only 4 pins are available (MIC[+,-] and SPK[+,-]). So
a headset can be connected (see Appendix chapter
This interface supports also a connection to an external device such as active
headset.
