Abstract: A broadband network, such as a cable television (CATV) system, for two-way digital communications between a headend and a number of remote terminals dynamically adjusts the power of the upstream signal transmitted by each remote terminal to maintain the bit error rate (BER) of the upstream signal received by the headend below a predetermined limit. In particular, each remote terminal includes a data receiver for receiving signals from the headend (including control signals), and a data transmitter for transmitting digital data signals upstream to the headend. The power level of the data transmitter can be adjustably controlled by the control signals from the headend.

Abstract: An improved F-connector for use in CATV, MATV and general television applications where coaxial cables and/or other devices must be connected to other cables or devices, the connector having an improved flat port through which internal components are inserted into a connector housing and which is thereafter formed by insertion of a flat insert or end cap which is fitted into the end of the connector housing and abuts against an internal shoulder therein.
