General Safety

Ground the Equipment

Electro-Static Discharge

To minimize shock hazard, the equipment chassis and enclosure must be connected to an electrical earth ground. The power cable must be either plugged into an approved three-contact electrical outlet or used with a threecontact to two-contact adapter. The three-contact to two-contact adapter must have the grounding wire (green) firmly connected to an electrical ground (safety ground) at the power outlet. The power jack and mating plug of the power cable must meet International Electrotechnical Commission (IEC) safety standards.

Motorola strongly recommends that you use an anti-static wrist strap and a conductive foam pad when installing or upgrading the system. Electronic components, such as disk drives, computer boards, and memory modules, can be extremely sensitive to Electro-Static Discharge (ESD). After removing the component from the system or its protective wrapper, place the component flat on a grounded, static-free surface, and in the case of a board, componentside up. Do not slide the component over any surface.

If an ESD station is not available, always wear an anti-static wrist strap that is attached to an unpainted metal part of the system chassis. This will greatly reduce the potential for ESD damage.

Do Not Operate In An Explosive Atmosphere

Do Not Service Or Adjust Alone

Use Caution When Exposing Or Handling a CathodeRay Tube

Do Not Substitute Parts Or Modify Equipment

Do not operate the equipment in the presence of flammable gases or fumes. Operation of any electrical equipment in such an environment constitutes a definite safety hazard.

Do not attempt internal service or adjustment, unless another person, capable of rendering first aid and resuscitation, is present.

Breakage of the Cathode-Ray Tube (CR T) causes a high-velocity scattering of glass fragments (implosion). To prevent CR T implosion, avoid rough handling or jarring of the equipment. The CRT should be handled only by qualified maintenance personnel, using approved safety mask and gloves.

Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modification of equipment. Contact Motorola Warranty and Repair for service and repair to ensure that safety features are maintained.

QUAD Channel 900 MHz Base Radio

Theory of Operation

The QUAD Channel 900 MHz BR operates with other site controllers and equipment and must be properly terminated. The following description assumes such a configuration. Figure 1-10 show an overall block diagram of the QUAD Channel 900 MHz BR.

Power is applied to the DC Power inputs located on the QUAD Channel 900 MHz BR backplane. The DC Power input is connected if -48 VDC or batteries are used in the site.

Power is applied to the BR by setting the Power Supply power switch to the ON position. Upon power-up, the QUAD Channel 900 MHz BR performs self-diagnostic tests to ensure the integrity of the unit. These tests, which include memory and Ethernet verification routines, primarily examine the EX / CNTL.

After completing self-diagnostic tests, the QUAD Channel 900 MHz BR reports alarm conditions on any of its modules to the site controller via Ethernet. Alarm conditions may also be verified locally. Local verification involves using the service computer and the STA TUS port located on the front of the QUAD Channel 900 MHz EX / CNTL.

The software resident in FLASH on the EX / CNTL registers the BR with the site controller via Ethernet. After BR registration on initial power-up, the BR software downloads via resident FLASH or Ethernet and executes from RAM. The download includes operating parameters for the QUAD Channel 900 MHz BR. These parameters allow the QUAD Channel 900 MHz BR to perform call processing functions.

Enhanced Base Transceiver System (EBTS)

1-18 68P80801E35-E 16-June-06

Volume 2 Base Radio

QUAD Channel 900 MHz Base Radio Overview

After software downloads to the BR via Ethernet, FLASH memory stores the software object. Upon future power-ups, the software object in FLASH loads into RAM for execution.

The BR operates in a TDMA (Time Division Multiple Access) mode. This mode, combined with voice compression techniques, increases channel capacity by a ratio of as much as six to one. TDMA divides both the receive and transmit signals of the BR into six individual time slots. Each receive slot has a corresponding transmit slot. This pair of slots comprises a logical RF channel.

The BR uses diversity reception for increased coverage area and improved quality. The Receiver modules within the QUAD Channel 900 MHz BR contain three receiver paths. Two-branch diversity sites use two Receiver paths, and three-branch diversity sites use three Receiver paths.

All Receiver paths within a given Receiver module are programmed to the same receive frequency. Signals from each receiver arrive at the EX / CNTL module. This module performs a diversity combining algorithm on the signals. The resultant signal undergoes an error-correction process. Then, via Ethernet, the site controller acquires the signal, along with control information about signal destination.

Two separate FRUs comprise the transmit section of the QUAD Channel 900 MHz BR. These are the Exciter portion of the EX / CNTL and the Power Amplifier (PA). The Exciter processes commands from the CNTL, assuring transmission in the proper modulation format. Then the low-level signal enters the PA. The PA amplifies this signal to the desired output power level. The PA is a continuously keyed linear amplifier. A power control routine monitors the output power of the BR. The routine adjusts the power as necessary to maintain the proper output level.

900 MHz QUAD Channel Base Radio Controller Overview

Figure 2-6 900 MHz QUAD Channel Base Radio Controller, version DLN1203 (with cover

removed)

The Base Radio Controller (BRC) provides signal processing and operational control for Base Radio modules. The BRC module consists of a printed circuit board, a slide-in housing, and associated hardware.

The BRC memory contains the operating software and codeplug. The software defines BR operating parameters, such as output power and operating frequency.

The BRC connects to the Base Radio backplane with one 168-pin FutureBus+ connector and one blindmate RF connector. Two Torx screws secure the BRC in the Base Radio chassis.

Figure 2-6 shows a top view of the EX/CNTL (model CLF1560) with the cover removed.

The BRC monitors the functions of other Base Radio modules. The LEDs on the front panel indicate the status of BRC-monitored modules. All LEDs on the BRC front panel normally flash three times upon initial power-up. A RESET switch allows a manual reset of the Base Radio. Figure 2-7 shows the front panel of the BRC.
