Abstract: This invention provides a level control system for achieving a consistent desired signal level at each of the outlets (27) of a broadband signal distribution system where the outlets (27) are each subject to signals experiencing varying amounts of attenuation. The level control system has two subsystems (10, 80). The cable system level control subsystem (10) consists of a closed loop feedback circuit having an RF pilot detector (60) for detecting a pilot signal generated at the distribution unit (38), a level control circuit (62), and a pair of cable simulating attenuators (16, 19) which are controlled by the level control circuit (62). The modulator level control subsystem (80) consists of a pair of flat response attenuators (86, 88) connected in series and a closed loop feedback circuit consisting of a broadband RF detector (96) and a level control circuit (98) connected to the output of the broadband RF detector for driving both flat response attenuators (86, 88) whereby a desired signal level output is achieved on the system output (21).

Abstract: A keying system for an electrical connector (10, 16) is disclosed. Keying members (160, 234) are provided in mating pairs so that one is assembled to the cable connector (10) and the other is assembled to the mating panel connector (16). Each of the keying members (160, 234) is assembled by inserting it into the open end of the connector so that lugs (186, 236) in the dielectric insert (44, 218) within the connector enter camming slots (178) in the keying member (160, 234) which is then twisted to lock it in place. The keying members can be easily and conveniently assembled and disassembled in the field by the end user.
