Caution

These servicing instructions are for use by qualified personnel only. To reduce the risk of electrical shock, do not perform any servicing other than that contained in the Installation and Troubleshooting Instructions unless you are qualified to do so. Refer all servicing to qualified service personnel.

Special Symbols That Might Appear on the Equipment

This symbol indicates that dangerous voltage levels are present within the equipment. These voltages are not insulated and may be of sufficient strength to cause serious bodily injury when touched. The symbol may also appear on schematics.

The exclamation point, within an equilateral triangle, is intended to alert the user to the presence of important installation, servicing, and operating instructions in the documents accompanying the equipment.

For continued protection against fire, replace all fuses only with fuses having the same electrical ratings marked at the location of the fuse.

FCC Compliance

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the Installation Manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his/her own expense. Any changes or modifications not expressly approved by Motorola could void the user’s authority to operate this equipment under the rules and regulations of the FCC.

Canadian Compliance

This Class A digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations. Cet appareil numérique de la classe A respects toutes les exigences du Règlement sur le matériel brouilleur du Canada.

BLE*/* Installation and Operation Manual

Section 1

Introduction

The Motorola STARLINE® series of broadband line extenders, BLE*/*, accept a single input and provide 28 through 32 dB of operational gain (depending on model) to a single output. The BLE*/* series of line extenders meets Telcordia GR-1098 core voltage surge requirements using surge waveforms as described in IEEE C62.41. The BLE*/* is also FCC, CE, and CCC approved.

Features of the BLE*/* include:

870 MHz power doubling technology in enhanced gallium arsenide (E-GaAs)

Five different modular diplex filter splits

“Ease of use” ergonomics

60/90 Vac line power option

Thermal and auto-controlled Bode equalization

20 dB directional coupler test points

Optional return path ingress control and LIFELINE® status monitor

Two-way operation capability

15-amp power passing

BLE*/* Installation and Operation Manual

Section 2

Overview

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. Installation of the optional return path enables two-way signal flow.

The standard model BLE*/* includes an amplifier module with an integrated dc power supply, which is normally furnished complete in the model BLE-HSG/15 housing, as shown in

BLE*/* Installation and Operation Manual

Overview

2-3

Housing

The BLE*/* is furnished in a BLE-HSG/15 aluminum housing that protects the electronics from weather and dissipates internally generated heat.

Figure 2-3 illustrates the BLE-HSG/15 housing and provides its dimensions:

Coaxial cable connections to the housing are made using conventional 5/8 inch × 24 threads per-inch stinger-type connectors. Four port plugs in the cover enable access to internal test points without opening the housing.

The BLE-HSG/15 differs from the housing of the 10A BLE (model BLE-75SH and BLE-75JH) and the JLX series of line extenders. However, you can upgrade the 10A BLE and the JLX series of line extenders to the 15A BLE*/* using the existing housing. To upgrade from 10A to 15A, use the BLE-15A platform assembly kit (P/N 951941-006-00). The BLE-15A kit contains 15A platform assemblies. As an alternative to the kit, you can order the current BLE*/* electronics module configured as a 10A unit (see Fig.2-2 BLE*/* Configurator, AC Current Capability).

Two messenger clamps are located in the side of the housing (Figure 2-5) and are secured with 5/16 inch × 24 threads-per-inch stainless steel bolts. The bottom of the housing also contains two 5/16 × 24 threaded holes located on the vertical center-line separated by four inches center-to-center. Use these holes and the bolts from the messenger clamps for pedestal and surface-mounting installations.

BLE*/* Installation and Operation Manual

Overview

Gaskets

Each housing is equipped with a recessed woven-wire RF gasket and a silicone-rubber gasket to provide a seal between the housing base and lid. These gaskets provide efficient ground continuity, RF shielding, and weather protection. Both gaskets must be in place and in good condition to ensure proper operation and protection of the station. The weather gasket should be lightly coated with silicone grease each time the BLE*/* is opened. Replace this gasket if it becomes damaged or deformed.
