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.
C a l l i n g f o r R e p a i r s If repair is necessary, call the Motorola Repair Facility at 1-800-227-0450 for a Return for Service Authorization (RSA) number before sending the unit. The RSA number must be prominently displayed on all equipment cartons.
S ec ti on 2 O v e r v i e w The BLE*/* is a two-way capable line extender used in CATV distribution systems. The BLE*/* is powered by the 60/90 Vac cable supply and can be configured to pass this power to additional line extenders.
C o n f i g u r a t i o n The BLE*/* is fully configured in the Motorola factory per customer request. It is recommended that you verify the configuration listed on the outside of the shipping carton with the configuration that you ordered.

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.
B e n c h T e s t i n g Motorola’s recommended procedure for placing a new BLE*/* into service is to fully test it on the bench before it is field installed. There are specific alignment procedures that ensure proper functioning of all components and simplify final installation.
