General Product Information
1 Introduction
The General Product Information provides general information on
unconfigured radio base stations. Refer to the RBS 884 Site Engineering
Manual for descriptions of the available working base station configurations
and for information on RBS interfaces (for instance, power, transmission,
and antennas).
2 Features
The RBS 884 Series is a series of products in the CMS 8800 family. The
products in the RBS 884 Series are fully featured modular RBSs for both
the analog AMPS EIA 553 and the digital D-AMPS EIA IS 136 systems
(Advanced Mobile Phone System Electronics Industry Association 553
system and Digital American Mobile Phone System Electronics Industry
Association Interim Standard 136 system).
A base station in the RBS 884 Series can support one, two, or three cells. A
cell is a defined area covered by one antenna system, and each cell has one
control channel for digital or one for analog, or both. There is one cell at an
omni site, and one to three cells at a sectorized site.
The RBS 884 Series utilizes multi-mode, multi-functional transceivers
(TRXs). The same hardware TRX module can be used for analog and digital
voice, control and monitoring purposes.
The hot repair capability allows replacement of defective units when power
is still applied.
The RBS 884 Series is designed for remote control monitoring allowing
control and fine tuning of all functions and parameters, such as power output,
frequencies, and switching of redundant units from the MSC.
A Radio Frequency Test Loop (RFTL) is an optional feature that enables
precise output power settings, Voltage Standing Wave Ratio (VSWR) alarm,
and Receive Signal Strength Indicator (RSSI) test measurements.
The device software is stored in non-volatile memory within the RBS, and
the control part software is downloaded from the MSC, which ensures a
short time to service at power-up.

General Product Information
The RBS 884 Series includes product lines for macro and micro cells. See
Figure 2-1 on page 2-4.
Note: The maximum number of carriers for each sector stated is the
technical limitation for the defined standard configurations. The
practical usable sector sizes may be limited by the frequency
plan. The capacity of all product lines, with the exception of the
RBS 884 Micro (1900 MHz) is calculated for analog systems.
The capacity of the RBS 884 Micro (1900 MHz) is calculated for

Figure 3-3. General Overview of RBS 884 Configuration
The Group Switch (GS) at the MSC is responsible for switching calls between
subscriber terminals. The calls can be between two mobile subscribers
or between a mobile subscriber and a subscriber in the public telephone
network. The RBS contains several regional processors which are controlled
by and work with the central processor. The regional processors control the
switch and the transceivers (TRXs) in the base station. The switch in the base
station ensures the speech signals from the MSC are connected to the correct
TRX. The TRXs generate RF that is emitted by the base station antenna to
the mobile terminals. The semipermanent connections are set up in the MSC.
Figure 3-4 on page 3-7 shows the logical parts of an RBS.

The logical parts of the RBS 884 Macro are as follows:
• Control Part (COP) – provides communication between the MSC
and the RBS hardware for radio traffic control and statistical data
gathering. In the RBS 884 Macro, the COP consists of Control and
Radio Interface (CRI) cabinet.
• Modem Part (MOP) – converts digitized speech and data into radio
frequency signals, hosts channel coding and decoding functions,
and performs measurements on radio transmission quality. It is
comprised of transceiver modules (TRXs) in the RBS and voice
coders (TRABs) in the MSC. In the RBS 884 Macro, the MOP
consists of the Transceiver cabinet (TCB).
• Antenna Near Part (ANP) – contains components associated with the
RF signal paths, such as combiners, power splitters, multicouplers,
2/1551-AE/LZB 119 4239 Uae Rev A 2001-03-15 3-7
System Description
and bandpass filters. In the RBS 884 Macro with MCPA the ANP
consists of the Antenna Near Part Cabinet (ANPC) and the Hybrid
Combiner Cabinet (HCC). The combined ANP/RFTL/Filter unit
provides RSSI measurement, output power measurement and
calibration, VSWR supervision, and RF path testing. The main
functions of the ANP are as follows:
– Combine multiple TRX output signals to a single TX antenna
– Filter TX and RX signals
– Pre-amplify and distribute RX signals
– Protect TRXs from reflected power
– Provide isolation between the TRXs
– Calibrate and supervise the TRXs and associated RF components
• Support Part (SP) – provides general support, such as power supply
and cooling. The components of this part vary significantly between
the product lines.
3 RBS Overview
The Macro with MCPA, 1900 MHz is a modular RBS that supports digital
Time Division Multiple Access (TDMA). The RBS is an omni-site consisting
of one standardized 19” rack of radio equipment and one 24” rack with
MCPAs. Additional RBS equipment racks are combined a to form two-
and three-sector systems.

The Exchange Terminal Boards (ETBs) end the PCM links and connect the
RBS to the MSC. The control signals for the RBS are carried on one time
slot of the PCM link, and are ended by the Signal Terminal Receiver (STR).
A set of Extension Module Regional Processor Speech Bus Interfaces
(EMRPSs) is used to control the devices on a load sharing basis.
Communication Links (C-links) connect device equipment (TRX, ALM,
RFTL, and TIM) to the Radio Transceiver Terminals (RTTs).
A Node Clock Time Switch (NTSW) connects control paths from the
EMRPSs to the devices. The time switch also routes the traffic data on paths
set up between a time slot on an ETB and a device connected to an RTT. The
time switch is controlled by a dedicated EMRP.
The received RF signal is split to all Transceiver modules (TRXs) by the
Power Splitters (PSPs) and the Power Splitter backplane in the Transceiver
Cabinet (TCB).The RF output from the TRXs are connected to the HCC.
Figure 3-7 on page 3-11 is an example of unit interaction in the HCC and
ANPC. The configuration shows separate receive and transmit antennas.

The receive antenna signal input is first passed through a Receiver Bandpass
filter (RXBP). It is then fed to the Multicoupler A (MC A) and B (MC B)
units, where the signal is amplified to compensate for Power Splitter (PSP)
losses. The multicouplers also receive signals from the Radio Frequency
Test Loop (RFTL) unit so that the receive path can be tested. Multicoupler
outputs are fed to the PSPs, which distribute the signals to the TRXs through
the TCB backplane. Each TRX receives both A- and B-branch receive
signals and demodulate the signals to baseband.
TRX transmit outputs are connected to the combiners where they are
combined into one signal. This signal is directed to the MCPA, Transmitter
Bandpass (TXBP) filter, and Measurement Coupler Unit (MCU), after
which it is output to the antenna. The MCU acts as an interface to the Radio
Frequency Test Loop (RFTL), which performs various tests on the RF
signals, such as measuring forward and reflected power.

3.2 Call Paths
3.2.1 Receive Path
As shown in Figure 3-8 on page 3-12, the received signal is passed through
the Receiver Bandpass (RXBP) filters in the TMAs (if used) and ANPC.
The signals are fed to MCUs, MC-A, and MC-B, that amplify the signal to
compensate for Power Splitter (PSP) losses. The MCs also receive signals
from the Radio Frequency Test Loop (RFTL). The MC outputs are fed to the
PSPs which distribute the signals through the TCB backplane to the TRXs.
Each TRX receives both A- and B-branch receive signals and demodulate
the signals to baseband. Nominal gain from the receive antenna is 5.2 dB
(6.5 dB with a TMA).

3.3 Signaling
3.3.1 Control Signaling
Control signaling for RBS equipment is as follows:
• The MSC Central processor (CP) sends the control signal to the
Signaling Terminal Central (STC) board.
• The STC board converts the signal format and sends the signal to the
Exchange Terminal Circuit (ETC).
• The ETC inserts the control signal into a time slot on the PCM (T1)
link to the Control Radio Interface (CRI).
• The control signal in the time slot is extracted by the Exchange
Terminal Board (ETB) and sent to the Signaling Terminal Regional
(STR).
• The STR converts the information back to processor format and
outputs it on the Extension Module Regional Processor Bus
(EMRPB).
• The EMRPB and the Extension Module Regional Processor with
Speech Bus (EMRPS) boards are connected to the EMRPB.
2/1551-AE/LZB 119 4239 Uae Rev A 2001-03-15 3-13
System Description
– The EMRP controls equipment in the CRI cabinet including the
Node Clock Time Switch (NTSW) and ETB boards
– The EMRPS is an EMRP with extended processor power and
a speech bus interface. It is connected to both the EMRP bus
and the TSW speech bus and controls equipment in the TCB
and ANPC. These boards also facilitate communication with
the MSC’s Man-Machine Interface (MMI) by providing a V.24
interface for a teletype or Typewriter (TW) peripheral.
3.3.2 Speech Signaling
Speech signaling for RBS equipment is as follows:
• A speech or data signal from the Public Telephone Switching
Network (PSTN) is received by the group switch (GS) at the MSC
• A digital call is:
– Routed to the Transcoder and Rate Adaptation Board (TRAB)
– Converted into compressed format used in the air interface either
with Algebraic Code Excited Linear Prediction (ACELP) or
Vector Sum Excited Linear Prediction (VSELP)
– Combined with two other voice paths which share same
frequency
– Routed to the correct Exchange Terminal Circuit (ETC)
• The signal is sent over a T1 line to the Control and Radio Interface
(CRI) where it is:
– Routed to an Exchange Terminal Board (ETB)
– Routed through the Time Switch (TSW)
– Routed to a Radio Transceiver Terminal (RTT), which is an
interface to a transceiver (TRX) in the Transceiver Cabinet
(TCB) via a Communication Link (C-link)
• In the TCB the signal is passed through a Transceiver (TRX) where
it is :
– Converted to RF
– Sent to the Hybrid Combiner (HCC)
• In the HCC, signals are combined 16:1 and then combined 2:1
(32:1) and sent to the MCPA
• The MCPA sends the signal to the TXBP and MCU where it is
sent to the ANPC
• In the ANPC, RF is coupled to the antenna(s)

3.4.1 Network Synchronization
Network Synchronization is provided by the ETB with buffers and the
NTSW clock for error-free transmission of data to and from the MSC. The
clock is locked to the reference signal provided from the MSC. The signal is

System Description
superimposed on the traffic link connecting the RBS to the MSC. Using this
signal, the ETB creates a synchronization clock with a frequency of 8 kHz.
3.4.2 Carrier Frequency Synchronization
Carrier Frequency Synchronization is provided by the NTSW and TIM. The
8kHzclockisscaleddownto4kHzbytheNTSWintoaMasterReference
(MR) signal (see Figure 3-10 on page 3-15). The MR is used by the TIM to
generate a 64 kHz Carrier Frequency Reference (CFR) that is distributed to
the TRXs via the RTTs and the C-Links.
Carrier Frequency Stabilization is handled by the TIM and holdover is at
least 72 hours after a loss of the synchronization signal on the network. To
obtain carrier frequency accuracy, the reference signal must be traceable to a
source of Stratum 2 level or better.
3.4.3 Air Frame Synchronization
Air Frame Synchronization phase aligns all air frames transmitted from the
RBS. The TIM provides the synchronization that is distributed to each TRX.
The DCON board provides daisy-chain connections between TCBs.
3.5 CRI and PCM Link Configuration (T1)
The Extension Module Regional Processor (EMRP) bus is the local
comunication link between the regional processors (RPs) and the Signal
Terminal Regional (STR). The STR and the Signal Terminal Central (STC)
in the MSC make up the control link between any RP and the central
processor (CP).
The CRI can be configured with two EMRP buses, A and B, to facilitate
multiple PCM links. Up to four (4) PCM (T1) links can be connected to three
CRIs. Each CRI-CRI connection can cascade in both directions to allow time
slots to be routed from any incoming PCM (T1) to any of the three sectors.
Figure 3-12 on page 3-18 shows the 3x15 configuration.
The first PCM (T1) link is connected to ETB-1 in CRI-a. Eight time slots are
used in Sector A and the remaining sixteen time slots are routed to Sector B
and Sector C. Eight time slots are routed from ETB-3 in CRI-a to ETB-2 in
CRI-b. Also, eight time slots are routed from ETB-2 in CRI-a to ETB-2 in
CRI-c. As a result, eight time slots are available in each sector.
The second PCM (T1) link is connected to ETB-1 in CRI-b. Eight time slots
are used in Sector B and the remaining sixteen time slots are routed to Sector
A and Sector C. Eight time slots are routed from ETB-2 in CRI-b to ETB-3
in CRI-a. Also, eight time slots are routed from ETB-3 in CRI-b to ETB-3
in CRI-c. It should be noted that this configuration re-routes the time slots
from ETB-3 in CRI-b back to ETB-3 in CRI-a on the same physical link as

the original eight time slots from Sector A to Sector B. This bidirectional
configuration results in 16 time slots in each sector.
The third PCM (T1) link is connected to ETB-1 in CRI-c. Eight time slots
are used in Sector C and the remaining sixteen time slots are routed to
Sector A and Sector B. This bidirectional configuration results in 24 time
slots in each sector.
