    I n t r o d u c t i o n  The Motorola STARLINE series of broadband line extenders, BLE*/*, accept a single input and provide 28 through 30 dB of operational gain (depending on model) to a single output. The high gain makes the BLE*/* series ideally suited for a hybrid fiber-coax system as well as conventional tree and branch designs.

    Return levels used for alignment are not necessarily operational system levels. These levels vary from system to system due to differences in equipment, architectures and design philosophies. For an in-depth analysis and discussion of the return path, refer to Motorola reference guide Return Path Level Selection, Setup and Alignment Procedure.
