Document Scope

The product descriptions and specifications in this document are based on the best

information currently available for the Motorola UBS Base Transceiver Subsystem (BTS)

operating at 800 MHz, BC0 or 1.9 GHz, BC1 or BC14 (BC1 + G block), supporting

CDMA2000 1X and EVDO carriers. However, changes to hardware, software and/or

standards may result in changes being made to the content of this document. Motorola

reserves the right to make changes to these specifications without notice.

This version describes the UBS based on its functionality as supported by CSD Release 20.

Future CSD Releases will require updates to this document to describe any new functionality

or features that become available.

1.0 Architectural Overview of UBS System

A cellular Base Transceiver Subsystem (BTS) is one part of a cellular infrastructure system.

The basic functions of cellular infrastructure equipment are to provide the fixed end of the

radio interface to subscriber cellular phones and to route voice and data traffic to and from

the Public Switched Telephone Network (PSTN). For Release 20, the BTS will operate in

packet mode, which will route packet data to and from the IP network. The diagram shown

in Figure 1 illustrates the architecture with the data, voice and control paths for the sub-

systems in the UBS system.

The following summary describes the elements in a Radio Access Network (RAN).

Additional information regarding each element can be found in their respective specification

documents (B1) and other resources, such as the System Equipment Planning Guide (SEPG).





A Centralized Base Station Controller (CBSC) and Operations and Management Centers for

Radio (OMC-R) and IP (OMC-IP) provide call control, operations, maintenance, and

transcoding capabilities for the BTS. The Mobility Manager (MMII) is a subsystem of the

CBSC and provides the central processing unit for the BSC responsible for high-level call

processing. The MMII also provides the radio channel control functions and interfaces with

the OMC-R. The OMC-DO and BSC-DO provide call control, operations and maintenancecapability for EVDO carriers.

The Universal Network Operations (UNO) provides integrated support for CDMA, OMC-R,

BSC, BTS and Cisco Systems Packet Data Services Network (PSDN), and other network

interface devices. UNO supports device status, alarm, performance, and configuration

management. The Selector Distribution Unit (SDU) performs selection, distribution, and

packet control functionality. The Voice Processing Unit (VPU) performs transcoding

between the PCM and digital vocoding, along with echo cancellation.

The PDSN serves as a gateway between the landline Internet Protocol (IP) Data Network and

the Cellular system. The Access Node provides the transport focal point to interconnect thevarious network elements within the IP based RAN for delivery of control and bearer traffic.

The System Monitoring Application Processor (SMAP) can provide a CDMA call trace

session, collect, log, and analyze RF data.

1.1 UBS CDMA BTS

The UBS is a single frame (Figure 3) indoor base station designed to support low to high density

macro cell sites. The UBS’s flexible design will allow growth and enhancements from the

current 2 DMI, 2 XMI configuration up to 4 XMI, 5 DMI configurations.

The UBS base configuration consists of: Manufacturing level kit, frame assembly hardware,

Transceiver Module (XMI), Digital Module (DMI), mounting shelf, Site Span Interface (SSI),

duplexor panel housing, and Power Distribution Unit (PDU). The DMI module contains sitecontrol and modem functionality. The modem modules include 1X modems (with each modem

supporting 256 channel resources) and/or EVDO Modems. Additional modules include DMI

power cables and XMI to DMI cables. The SSI kit consists of balanced span kits (BTS hardware

supports up to 8 T1/E1 lines), SSI power cables, and SSI-to-DMI cable kits. RF cabling kits

support 1S or 3S configurations. Lastly, filters must then be selected, depending upon the market

requirements for each region.





Optional Items: -48v Power Supply Module (PSM), -48v PSM shelf, AC PSM, AC PSM shelf,

PSM shelf SSI cables, PSM shelf interconnect options, back-up timing options (QHSO), RGPS

option, and breaker module assemblies.

1.2 UBS Functional Overview

This section of the B1 provides information on the basic operation of the UBS at 800 MHz or

1.9GHz. The following topics are discussed:

• Transmit path

• Receive path

Transmit and Receive Paths

The XMI supports 10MHz in the transmit path and 10MHz in the receive path for the

800MHz configuration. In the 1.9GHz configuration, the XMI supports 6.25MHz in the

transmit and receive paths.

The XMI is compatible with future UBS configurations which will support antenna sharing.

This does not preclude sharing transmit or receive antennas through use of external

duplexing, combining or splitting equipment.

2.1 DMI

The Integrated Digital Module (DMI) contains two main components: a controller and the

modems. A DMI contains a single controller which provides connections for two modems. A

DMI can be populated with one or two 1X modems or EVDO Modems, or a combination of

one 1X modem and one EVDO modem, depending upon the configuration required at the

BTS. In the forward direction (BTS→ Mobile), the DMI terminates the backhaul control and

bearer connections from the SSI, processes the bearer and control plane data then passes the

baseband data to the XMI for conversion to RF and transmission over the air. In the reversedirection (Mobile→ BTS), the DMI receives baseband data from the XMI after conversion

from RF, processes it and generates the associated control and bearer plane data for

transmission to the network via the SSI card.

External interfaces on the DMI include the following:

• +27V DC (nominal) power input

• Local Maintenance PC interface

• Two SSI/One IDI interfaces

• Two XMI interfaces

The Controller within the DMI provides all of the DMI external interfaces as well as

positions to connect two modem cards. The controller is made up of the following functions:

Site Processor (SPROC), Synchronization, Interworking (protocol termination), DMI

baseband processing, XMI interfaces and SSI interface.

The DMI maintains CDMA system time and generates the master clock and reference signals

for other CDMA system modules. The DMI provides timing and synchronization functions

and control functions for the MSO, QHSO, and RGPS through the SSI. To provide the

required synchronization for the UBS, the DMI can utilize multiple timing sources. Currently

supported sources are the GPS receiver, internal backup timing reference (MSO), and a

separate backup timing reference (QHSO). The GPS receiver is the primary source and either

the MSO or QHSO serve as the redundant source.





The UBS supports 1X and EVDO modems for the DMI. Each 1X modem supports up to 256

1X Channel Elements (CE) and up to 12 1X sector-carriers and each EVDO modem supports

up to 114 MAC-IDs per sector-carrier and up to 3 sectors carriers1.

A single DMI equipped with two 1X modems can support up to 512 1X CE if fully

provisioned. 1X modems in a DMI are pooled (i.e., support the same set of sector-carriers, 12

Max per DMI) to provide a greater number of available traffic channels. With pooling,

overhead channels are supported and required on both modems for redundancy. The UBS

will support a single paging channel per carrier. EVDO Modems are not pooled.

2.2 XMI

The UBS utilizes an Integrated Transceiver / Power Amplifier Module (XMI) that provides

both the base-band transceiver and linear power amplifier functionality for the BTS. This

functionality is integrated within a single module. The UBS frame can be configured with

one or two XMIs.

The XMI supports 10 MHz in the transmit path and 10 MHz in the receive path, for800MHz, and 6.25MHz for the 1.9GHz transmit and receive paths. All carriers must be

within the supported ranges or less. When carriers are mapped to the XMI, they may be

either adjacent or non-adjacent within the bandwidth constraint of the target XMI. The XMI

receiver is capable of supporting four carriers in the three-sector configuration and eight

carriers in the Omni configuration.

The XMI module supports trunking, which enables dynamic power sharing among all sector-

carriers. An advantage of trunking is that power can be distributed among sector-carriers

with different loads. The built-in redundancy of trunking is also an advantage. If one of the

XMI’s internal power amplifiers fails, all sector-carriers served by that XMI can still operate

at reduced power on the remaining power amplifiers. The XMI will generate a system alarmto alert the operator of the failure condition but will stay in service.

The XMI is designed to support soft fail redundancy. When a failure occurs in a component

or function within the XMI for which there are multiple instances of that function, the UBS

attempts to keep the XMI in service. A failure of one of these functions within the XMI

results in a soft fail condition that may reduce parametric capability such as power,

performance, or capacity, but some parametric capability will remain such that the XMI

continues to provide transmit and receive functionality. The XMI is designed with multiple

power amplifiers and when failure of a single amplifier within the XMI occurs, degradation

in forward link gain and sector-to-sector isolation will occur but all carriers will remain

active. With failure of the Low Noise Amplifier (LNA) in one sector, the XMI will stay inservice with only the remaining receive path (main or diversity) for that sector and may lose

receive diversity for the carriers in that sector, but other sectors will not be affected.

1 Actual MAC-ID support may be limited by resource utilization within the EV-DO Rev. A modem

based on the number and type of active calls. The maximum number of MAC-IDs per EV-DO Rev. Amodem is 192.





The XMI provides main and diversity RX inputs for three sectors. The UBS supports soft-

fail redundancy at the module level, which allows the module to continue to operate at

reduced performance instead of taking the unit out of service.

2.3 SSIThe Site/Span Interface (SSI) provides the interface to the backhaul spans, RGPS, QHSO,

customer relay inputs/outputs, and the LMF. The UBS hardware currently supports 8 spans

of packet backhaul through either T1 or E1 spans. The SSI provides connections to the

customer defined inputs (24) and outputs (8).

• Balanced kit supports up to 8 T1/E1 balanced lines. Includes SSI mechanics kit and

SSI board assembly.

• SSI power cable kit – Connects the SSI to the power distribution

• SSI-to-DMI cable kit – Connects the SSI to the DMI.

2.4 PDU

The Power Distribution Unit (PDU) is the central power distribution point for the UBS. Itcontains input feeds which connect to the PSM shelves or directly to the external customer

provided +27VDC power. The PDU houses circuit breakers for each of the powered BTS

subsystems and contains bulk capacitance to stabilize the internal bus voltage, facilitate

subsystem hot-swap, and absorb surge energy.

2.5 Global Posit ioning System (GPS)

There are two types of GPS receivers for the UBS frame. Remote Global Positioning System

(RGPS) is a remote receiver and antenna assembly that allows the UBS to provided precise

GPS timing information to the DMI controller. The RGPS is used for situations where long

cable lengths are needed between RGPS receiver/antenna and the BTS. The External Global

Positioning System (EGPS) module allows for a direct connection to a RF GPS antenna. TheEGPS device is mounted within the UBS rack.

2.6 IDRF Filtering

The UBS requires duplexers and receive filters in the RF path. The Integrated Duplexer

Receive Filter (IDRF) provides duplex and integrated transmit and receive filtering packaged

in a single module.

• The appropriate filter needs to be ordered that pertains to each country’s market

requirements. US full band filter will be offered as standard equipment, and the A/B

band filters can be configured as an option.

• Optional “Site Filters” can be ordered that provide exceptional selectivity in the 800

MHz A and B bands. Full band site filters are not available.

• China and India GSM rejection filters, that enable CDMA to co-exist with GSM

system, are also available options.

• Terminators to be equipped on unused TX ports





2.7 Optional Equipment

2.7.1 Backup Timing Options (Optional)

In order to support soft handoff capabilities between base stations, CDMA communications

systems require a high degree of network synchronization. In the event of failure of the primary timing source, it is required that the base station maintain time alignment for a

minimum of eight hours. The support for eight hours of time alignment after loss of GPS is

built into the controller of the DMI. Support for 24 hours of backup time is provided to the

UBS by the optional Quartz High Stability Oscillator (QHSO), which is a module that can be

mounted within the UBS rack.

2.7.2 Power Supply Module (PSM) (Optional)

The Power Supply Module is used to convert AC or -48VDC input power into +27VDC

power that can be used by the internal components of the UBS. The current UBS can

facilitate 1 PSM shelf, which can accommodate up to 3 PSMs. The power supply shelf can

be populated with, either AC PSMs or -48V PSMs.While operating in an AC configuration, the UBS can be powered from either single or 3

phase inputs. If +27VDC input is provided to the UBS, neither the power supply shelf nor

any PSMs are required. The +27VDC power is a direct connection to the PDU.

2.7.3 Breaker Module Assemblies (Optional)

The breaker modules for the UBS are part of the PDU. The PDU allows for future expansion

of up to 4 XMI, 5 DMI, 2 Accessories, and 2 SSI breakers to be supported per PDU.

2.7.4 Environmental Enclosure (Optional)

The optional Environmental Enclosure provides physical protection and a stable environmentto the Mid-Cap UBS when deployed outdoors. The enclosure consists of a rugged physical

enclosure, a Direct Air Circulation System (DACS), AC rectification to provide 27V, DC

breakers and distribution, and smart management of the battery powered back-up system.

The power system also provides for managing the battery backup should AC power be lost,

and charging the batteries when AC power is restored.

The Environmental Enclosure will support a Mid-Cap UBS frame with the IDRFs mounted

in the front of the frame with the SSIs facing forward. Using the optional mid height

1350mm rack supports a configuration of 2XMI, 2 DMI, 2 SSI, 1 IDI, 1 BSI, 1 RX Splitter, 6

IDRFs or 3 IDRF + 3 cavity combiners, or 1 coherent combiner, and 4 RU of customer

equipment space. (Note the 1800mm rack will not fit in the enclosure).

The Enclosure employs DACS to circulate and filter the outside air. DACS utilizes a two-

stage air filter. The first filter provides filtration for relatively coarse particulate matter. The

second membrane filter provides filtration for fine particulates and moisture in the air.

An AC entry box supports surge protection from lightning and circuit breakers. Domestic

and International wiring are supported. The AC/DC power regulation system provides power





to the UBS and also charges the battery. Monitoring of the batteries, low voltage

disconnects, and system monitoring with alarm provisioning.

The cabinet top provides access for 6 RF ports (12 optional), 1 GPS antenna port, and one

AUX-DC power port. RF surge protection is required, one per port. The cabinet bottom

provides access for backhaul and alarm cables to the surge protected punch block.
