A type of adapter with two connectors of the same type and gender, making it possible to change the gender of the connector to which it is joined from male (with pins) to female (with sockets) or vice versa.
This allows two male or two female cable ends to be joined. Gender changers come in a wide variety of types and are specified by connector type and gender. An example is a V.35 to V.35 male/male gender changer, which can be used to connect two V.35 serial cables (or one cable and a CSU/DSU) that terminate with female connectors
Graphic G-3. Examples of V.35 gender changers.
Some gender changers can also act as adapters for different data interfaces. For example, a V.35 to RS-232 male/male gender changer can be used to connect a V.35 connection on a CSU/DSU (Channel Service Unit/Data Service Unit) to a router, using an RS-232 serial cable. Be sure that the pinning for such a gender changer is suitable for the type of equipment you want to connect because different pinnings might exist when different serial interfaces are connected.
