Interface C (8-pin RJ45 connector)
The TANGO modem provides 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
TANGO modem has 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 HA-88, which provided by Falcom GmbH, for
communication call. For more details about HA-88 see chapter
“Possible external devices”.
