EBTS System Manual - Vol 2 800/900/1500 MHz Base Radios

Foreword

Foreword

About This Manual

Volume 2 of the Enhanced Base Transceiver System (EBTS) manual, Base Radios ,
provides the experienced service technician with an overview of the EBTS
operation and functions, and contains information regarding the 800 MHz,
900 MHz, or 1500 MHz base radios.

The EBTS System has three major components:

❐

integrated Site Controller (iSC)

❐

Base Radios (BRs)

❐

RF Distribution System (RFDS)

Installation and testing is described in Volume 1, System Installation and Testing ,
and RFDS are described in Volume 3, RF Distribution Systems (RFDS) . Detailed
information about the iSC is contained in the iSC Supplement Manual,

68P81098E05 .

Target Audience

The information in this manual is current as of the printing date. If changes to
this manual occur after the printing date, they will be documented and issued as
Schaumburg Manual Revisions (SMRs).

The target audience of this document includes Þeld service technicians
responsible for installing, maintaining, and troubleshooting the EBTS.

In keeping with MotorolaÕs Þeld replaceable unit (FRU) philosophy, this manual
provides sufÞcient functional information to the FRU level. Please refer to the
appropriate section of this manual for removal and replacement instructions.

800/900/1500 MHz Base Radios EBTS System Manual - Vol 2

Foreword

Maintenance Philosophy

The EBTS has been designed using a Field Replaceable Unit (FRU) maintenance
concept. To minimize system down time, faulty FRUs may be quickly and easily
replaced with replacement FRUs. This helps to restore normal system operation
quickly.

Due to the high percentage of surface mount components and multi-layer circuit
boards, Þeld repair is discouraged. Faulty or suspectFRUs should be returned to
the Motorola Customer Support Center for further troubleshooting and repair.

Each FRU has a bar code label attached to its front panel. This label identiÞes a
sequential serial number for the FRU. Log this number whenever contacting the
Motorola Customer Support Center. For complete information on ordering
replacement FRUs, or instructions on how to return faulty FRUs for repair,
contact:

Nippon Motorola LTD. OR Motorola Customer Support Center
Tokyo Service Center 1311 East Algonquin Road

Single Carrier Base Radio Overview

NOTE

FCC Compliance Notice : The Base Radio (BR) is FCC

Compliant only when used in conjunction with
Motorola supplied RF Distribution Systems. Motorola
does not recommend that this BR be used without a
Motorola approved RF Distribution System. It is the
customerÕs responsibility to Þle for FCC approval if
the BR is used with a non-Motorola supplied RF
Distribution System.

Theory of Operation

The BR operates in conjunction with other site controllers and equipment that are
properly terminated. The following description assumes such a conÞguration.
Figures 1-3 and 1-4 show an overall block diagram of the BR.

Power is applied to the AC Power or DC Power inputs located on the BR
backplane. The DC Power input is connected if -48 Vdc or batteries are used in
the site. The AC Power input is used when 120/240 Vac service is used as a
power source within the site.

Power is applied to the BR by setting the Power Supply power switch to the on
position. Upon power-up, the BR performs self-diagnostic tests to ensure the
integrity of the unit. These tests are primarily conÞned to the BRC and include
memory and Ethernet veriÞcation routines.

After the self-diagnostic tests are complete, the BR reports any alarm conditions
present on any of its modules to the site controller via Ethernet. Alarm conditions
may also be veriÞed locally using service computer and the STATUS port located
on the front of the BRC.

The software resident in EPROM on the BRC registers the BR with the site
controller via Ethernet. Once registered, the BR software is downloaded via
Ethernet and is executed from RAM. Operating parameters for the BR are
included in this download. This software allows the BR to perform call
processing functions.

The BR operates in a TDMA (Time Division Multiple Access) mode. This mode,
combined with voice compression techniques, provides an increased channel
capacity ratio of as much as 6 to 1. Both the receive and transmit signals of the BR
are divided into 6 individual time slots. Each receive slot has a corresponding
transmit slot; this pair of slots comprises a logical RF channel.

1-6

The BR uses diversity reception for increased coverage area and improved
quality. The Receiver module within the BR contains up to three receivers. Two
Receivers are used with two-branch diversity sites, and three Receivers are used
with three-branch diversity sites.

68P81095E02-D 11/9/2000

EBTS System Manual - Vol 2 800/900/1500 MHz Base Radios

Single Carrier Base Radio Overview

All Receivers within a given BR are programmed to the same receive frequency.
The signals from each receiver are fed to the BRC where a diversity combining
algorithm is performed on the signals. The resultant signal is processed for error
correction and then sent to the site controller via Ethernet with the appropriate
control information regarding its destination.

The transmit section of the BR is comprised of two separate FRUs, the Exciter and
Power AmpliÞer (PA). Several PA FRUs are available, covering different
applications and power levels; these are individually discussed as applicable in
later subsections.

The Exciter processes the information to transmit from the BRC in the proper
modulation format. This low level signal is sent to the PA where it is ampliÞed to
the desired output power level. The PA is a continuous keyed linear ampliÞer. A
power control routine monitors the output power of the BR and adjusts it as
necessary to maintain the proper output level.

NOTE

FCC Compliance Notice : The Base Radio (BR) is FCC

Compliant only when used with Motorola-supplied
RF Distribution Systems. Motorola does not
recommend using this BR without a Motorola­approved RF Distribution System. If customer uses
the BR with a non-Motorola supplied RF Distribution
System, the customer is responsible for Þling for FCC
approval.

Theory of Operation

The QUAD Channel BR operates together with other site controllers and
equipment that are properly terminated. The following description assumes such
a conÞguration. Figures 1-5 show an overall block diagram of the QUAD Channel
BR.

Power is applied to the DC Power inputs located on the QUAD Channel 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 BR performs self-diagnostic tests
to ensure the integrity of the unit. These tests, which include memory and
Ethernet veriÞcation routines, primarily examine the EX / CN TL.

After completing self-diagnostic tests, the QUAD Channel BR reports alarm
conditions on any of its modules to the site controller via Ethernet. Alarm
conditions may also be veriÞed locally. Local veriÞcation involves using the
service computer and the STATUS port located on the front of the QUAD Channel
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 Ethernet and executes from RAM. The download includes
operating parameters for the QUAD Channel BR. These parameters allow the
QUAD Channel BR to perform call processing functions.

68P81095E02-D 11/9/2000

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.

800/900/1500 MHz Base Radios EBTS System Manual - Vol 2

QUAD Channel Base Radio Overview

The BR uses diversity reception for increased coverage area and improved
quality. The Receiver modules within the QUAD Channel 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 BR.
These are the Exciter portion of the EX / CNTL and the Power AmpliÞer (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
ampliÞes this signal to the desired output power level. The PA is a continuously
keyed linear ampliÞer. A power control routine monitors the output power of the
BR. The routine adjusts the power as necessary to maintain the proper output
level.
