Regulatory information

This part which provides the regulatory information concerning the BTS is split into

the following items:

European regulatory requirement compliance,

North American regulatory requirement compliance,

Compliances for other regions/countries,

Operation conditions,

Cable specifications,

Product labeling.

European regulatory requirement compliance

As a radio product, the Nortel Networks BTS18000 falls under the requirement of

the RTTE (Radio and Telecom Terminal Equipment) European directive

1999/5/EEC. The RTTE directive covers essential requirements in the field of:

protection of the Health and Safety of the user and any other person, including the

objectives with respect to safety requirements contained in the Low Voltage

directive (73/23/EEC).

the protection requirements with respect to EMC contained in Directive

89/336/EEC.

The equipment generates, uses, and can radiate radio frequency energy. If not

installed and used in accordance with the instruction manual, the equipment may

cause harmful interference to radio communications. However, there is no

guarantee that interference will not occur in a particular installation. If this

equipment does cause harmful interference to radio or television reception,

which can be determined by turning the equipment off and on, the user is

encouraged to try to correct the interference.

The EMC requirements have been selected to ensure an adequate level of

compatibility for apparatus at residential, commercial, and light industrial

environments. The levels however, do not cover extreme cases which may occur

in any location but with a low probability of occurrence. In particular, it may not

cover those cases where a potential source of interference which is producing

individually repeated transient phenomena, or continuous phenomena, is

permanently present, for example a radar or broadcast site in the near vicinity. In

such a case it may be necessary to either limit the source of interference, or use

special protection applied, to the interfered part, or both.

Note: For operation or maintenance inside Nortel Networks systems, the

antistatic wrist shall always be used to maintain the integrity of the

product.

BTS18000 Reference Manual

2 BTS18000 FUNCTIONALITY

2.1 GSM--UMTS dual technology proposal

The BTS18000 is designed to integrate, within the same cabinet, both

GSM/GPRS/EDGE and UMTS technologies.

This configuration is available on all GSM frequency variants (900, 1800, and 1900

MHz) and on both 1900 and 2100 MHz frequency variants for UMTS. The

maximum one--cabinet configuration is GSM S333 + UMTS STSR--2.

2.2 GSM features

The BTS18000 offers a set of features enhancing the Quality of Service and the

spectrum efficiency of the network such as:

Full support of GPRS data services.

Full support of EDGE 8PSK modulation.

Guaranteed --110 dBm dynamic single--branch receive sensitivity (GMSK

modulation) at the BTS antenna, without any tower--mounted Low Noise

Amplifier (LNA).

Improved receiver diversity gain using a Nortel Networks specific algorithm,

providing 5 dB or more diversity gain in most situations, when spatial diversity

and de--correlated antennas are used.

High output power with a 30W or 40W standard Power Amplifier (PA), and an

optional 60W High Power Amplifier:

•

30W/30W (GSM1800, GSM1900),

•

40W/40W for standard RM (GSM900),

•

60W/45W for GSM900 HPRM (GMSK/EDGE power).

The BTS18020 cabinet can also be used as a very high density BTS in

conjunction with an optional cabinet housing Multi Carrier Power Amplifiers

(MCPA) and TX/RX antenna combiners.

The MCPA feature (available only in GSM1900) allows high radio capacities

using fewer RF feeders (8--Carriers per feeder at 43 dBm typical between the

MCPA cabinet and the antenna) and antennas:

•

without the coverage penalties of hybrid combiner solutions,

•

without the frequency hopping limitations of cavity combiner solutions.

The MCPA feature leads to a S16.16.16 configuration in two BTS cabinets and

one MCPA cabinet. The BTS18020 cabinet then contains up to 27 TRX without

power amplification. This BTS configuration is ideal for urban deployment with

severe space limitations and high capacity demands without compromising radio

coverage. One of its major benefits is the antenna number limitation (two per

sector).

BTS18000 functionality Nortel Networks Confidential

2--2

PE/DCL/DD/0160

Dual--band GSM configurations with single--BCCH, built in a single or in

multiple BTS18000 cabinets.

Enhanced voice quality due to an innovative algorithm of interference

cancellation significantly reducing the end--user’s perception of errors generated

in the radio transmission.

Full RF power control range (static and dynamic).

Spectrum efficiency optimization with the support of the undisputed Nortel

Networks capacity features that provide high quality voice and data services to a

dense subscriber population, in a limited spectrum and at competitive cost.

These solutions include Fractional Frequency Reuse, Automated Cell Tiering

and Adaptive Multi Rate (AMR) support.

Best--in--class radio performance thanks to high sensitivity receivers, unique

interference cancellation and improved spatial diversity algorithms along with

high output power, providing optimum coverage and link quality for both data

and voice services.

High integration of advanced technology.

This in turn contributes to a significant reduction in required floor space, size and

equipment operating costs. This concept is adapted to stringent environmental

constraints and is leading to the best economic trade--off between initial and final

capacity.

In addition, the BTS18000 supports asymmetrical radio configurations such as

S963 in one cabinet.

Compatibility with the S8000 and S12000 BTSs:

•

through existing site synchronized co--location,

•

through the possibility to re--use existing site equipment (such as an

S8000/S12000 outdoor plinth).

Industry leading transmission solution including high signaling concentration on

the Abis interface and drop--and--insert capability.

As an example, a single timeslot is only required for carrying the signaling of a

S333 BTS.

Only two PCM timeslots over the Abis interface are required for each 8--radio

timeslot TRX.

For signaling:

•

only one PCM timeslot is required, with configurations up to S333,

•

only three PCM timeslots are required, with configurations up to S999,

•

only six PCM timeslots are required, with configurations up to S18.18.18.

The BTS18000 can support eight E1/T1 PCM links, with a granularity of four

E1/T1 per IFM board.

BTS18000 functionalityNortel Networks Confidential 2--3

BTS18000 Reference Manual

The drop--and--insert capability is used to reduce the number of PCM links

needed to connect the BTSsto their BSC. This can be implemented through chain

connection or loop connection, depending on the level of reliability required.

The BTS18000 supports the drop--and--insert function exactly the same way as

the S8000 and S12000 BTSs do. Therefore, it is possible to have the S8000,

S12000 and BTS18000 BTSs on the same chain or loop.

GSM/GPRS/EDGE and UMTS dual technology capabilities for operator

evolution to 3G data services.

2.3 GSM functions

The BTS18000 provides:

the radio interface with the mobile handsets,

the associated signal processing and the transmission interface with the Base

Station Controller (BSC).

The BTS18000 ensures the following main functions:

RF functions:

•

Antenna coupling and duplexing,

•

Power amplification,

•

Reception, including RF 2--way receive diversity,

•

Gaussian Minimum Shift Keying (GMSK) modulation/demodulation,

4.2 Interface Module (IFM)

The IFM is only used in the BTS18000 base cabinet. It is not present in theextension

cabinets. The IFM is composed of a single passive board with connections on the

IBP and on the front panel.

4.2.1 Main functions

The IFM provides connectivity and secondary protection (the level of protection

depends on the type of board, see Section 4.2.2 “Types of IFM board”)onthePCM

links. It provides:

E1 (120 ohms) or T1 (100 ohms) links from the Abis (front panel) with

secondary protection to the local ICM (back panel) and the redundant ICM

(cross--connect connector on front panel).

additional E1/T1 links from the other IFM (cross--connect connector on front

panel) to the local ICM (back panel).

The IFM also provides detection for this additional Abis link to the ICM.

external synchronization link from external source (CMCF phase 2 or GPS

antenna, on the front panel) to the local ICM (back panel) and the remote ICM

(cross--connect connector on front panel).

The active ICM provides an RS422 receive link to the GPS antenna, and retrieves

PPS synchro input from the antenna. The IFM provides antenna detection to both

ICMs.

cross--connect link between the remote ICM (cross--connect connector on front

panel) and the local one (back panel). This link conveys detection,

active/passive, synchro and signaling signals between both ICMs.

Each board has a different PEC/CPC code (for these codes, see the replacement

procedure in NTP < 162 >).

4.2.2.1 IFM board

The IFM board provides a level of secondary protection greater than or equal to that

provided by a CSU (Channel Service Unit). Consequently, IFM is the appropriate

board to use if a CSU is not being used to provide protection. The name on this board

is IFM.

4.2.2.2 IFM1 board

The IFM1 board provides a lower level of secondary protection than that provided

by the IFM board. If a CSU (Channel Service Unit) is being used to provide

protection, then the IFM1 board can be used instead of the IFM board. The name

on this board is IFM1.

4.2.2.3 Terms used in this NTP

Except for the level of secondary protection and the names that appear on the

boards, the two types of IFM board are identical. Throughout this NTP, the term

“IFM” is used in text and graphics. You should interpret this as a generic term that

covers both types of IFM board. If it is necessary to distinguish between the two

types of IFM board, then this is stated explicitly in the text.

4.2.2.4 Location in cabinet

The BTS18000 cabinet includes:

one mandatory even IFM (IFM--even), located:

•

in the upper shelf, for BTS18010 cabinet,

•

in the left shelf, for BTS18020 cabinet.

one optional odd IFM (IFM--odd), located:

•

in the bottom shelf, for BTS18010 cabinet,

•

in the right shelf, for BTS18020 cabinet.

4.2.3 Front panel

Figure 4--4 presents the IFM front panel. Except for the name IFM1, the IFM1

board is identical to the IFM board shown in Figure 4--4.

4.3 Interface Control Module (ICM)

The ICM is only used in the BTS18000 base cabinet. It is not present in the extension

cabinets. It is designed to manage the whole BTS18000 site in simplex or redundant

mode.

The ICM is composed of a single board with connections on the IBP and on the front

panel.

4.3.1 Main functions

The ICM in simplex mode covers the functions related to a complete site including:

support of drop--and--insert facilities for the PCM links with the BSC,

reference clock for the air interface, synchronized on the Abis PCM interface, a

synchronizing BTS or a GPS antenna,

GSM_TIME calculations with possible network synchronization,

switching of PCM slots,

conversion of electrical signals, from external to internal PCM data formats,

concentration of the data flow of the BTS,

configuration and supervision of all the modules.

Redundancy can optionally be introduced using two ICMs in the cabinet: one even

ICM (ICM0) and one odd ICM (ICM1). In such a mode, called duplex, there is one

active ICM and one passive ICM.

The even ICM (ICM0) shall be equipped in simplex mode and is the default active

ICM at start up.

In duplex mode:

the active ICM is the currently operational one, as opposed to the passive one,

the passive ICM is the currently non operational one, as opposed to the active

one.

The redundancy is static. If the passive ICM traps, the swap from passive to active

occurs, but the traffic is lost and the newly active ICM can accept new traffic.

Note: ICM chain switching may disturb punctually the Abis lines, as line

transceivers of both boards share the same signals. This disturbance may

last several microseconds to several milliseconds, depending on the

hardware implementation. These characteristics are also met on the BSC

interface boards.

In Holdover, the SYN LED indicates the clock source (PCM number) that the syn tries to

use for synchronization. In that case, the holdover LED (H) is ON on the active ICM.

Table 4--10 ICM SYN LEDs behavior

4.3.7 LEDs behavior at active ICM starting up

The specific LEDs behavior, when the active ICM starts up, is as follows:

When the BTS18000 is turned on, H (holdover) and ACT (active) LEDs

switch ON.

After the Built--in Self Test (BIST) sequence, the ICM searches for

synchronizing with the PCM0 link.

When the clock source is found, H LED switches OFF and synchro source

LEDs (SYN) switch ON (see Table 4--10).

Table 4--11 summarizes the behavior of corporate and specific LEDs when active

ICM starts up.

•

AC monitoring,

•

DC monitoring,

•

breakers status,

•

battery status.

Optional external alarm detection (up to eight customer alarms per ABM).

4.4.1.2 Bridge function

The ABM assures bridge functions between several interfaces:

On one side, it manages interface with ICM (one front panel D link or two in case

of ICM redundancy),

On the other side, the bridge manages one internal E link for ABM alarm function

and three E links to the RM modules.

The traffic management between all interfaces is automatic and does not need

specific configuration. It is kept available whatever the module software status, as

long as power is on.

4.5 Radio Module (RM)

4.5.1 Main functions

The RM is a complete GSM/GPRS/EDGE transmitter/receiver. The RM is in charge

of all processing related to the GSM TDMAs. It is designed to support three TDMA

(GSM or EDGE). It is logically equivalent to three TRXs (0, 1 and 2).

The RM may operate:

on a one--sector basis (three carriers per sector, O3 mode),

on a three--sector basis (one carrier per sector, S111 mode).

Maximum configurations for BTS18000 mono--cabinet with RM are S666, O18

and S99.

4.5.1.1 RX splitter function

The RM integrates a RX splitter function. It is inserted between the DDM and RM

RX paths (main and diversity). It allows splitting DDM RX outputs in order to reach

maximum configurations (one input to three outputs split for main and diversity

paths).

In order to fit both RM configurations (S111 and O3), this function is configurable

by RF switches. The commands of switches are provided by the DDM (DC

command multiplexed on RF signals on DDM RX outputs and automatic RX

splitter configuration by RF connection).

4.6 High Power Radio Module (HPRM)

4.6.1 Main functions

The HPRM is a variant of the RM with only a two--TDMA capacity, but with an

increased output power. It is logically equivalent to two TRXs (0 and 1).

The BTS18000 with HPRM is only available in GSM900 frequency band, as a first

step.

The HPRM can operate on:

one--sector basis (two carriers per sector, O2 mode),

two--sector basis (one carrier per sector, S11 mode).

Maximum configurations for BTS18000 mono--cabinet with HPRM are S444, O12

and S66.

4.6.4 Interface description

The HPRM provides the following interfaces:

radio interface:

•

two PA outputs, QN type 50 ohms connectors,

•

six RX inputs (three main, three diversity), QMA type 50 ohms connectors,

digital/power interface on the DBP (the same as for RM),

debug interface (the same as for RM).

4.6.5 HPRM LEDs behavior

The HPRM LEDs behavior is identical to the RM LEDs behavior. The TRX2 LED

of a HPRM remains always OFF. It is only tested during BISTs.

4.7 Dual Duplexer Module (DDM)

The operator can use different types of couplers to couple the PAs to the antennas

and to combine the RX and TX paths:

duplexers,

transmit filters,

hybrid combiners.

These couplers can be found in the following BTS18000 modules:

DDM or DDM with optional H2 coupling, both including an optional VSWR

meter,

TXF or TXF with optional H2 coupling, both including an optional VSWR

meter.

4.7.1 Main functions

The DDM allows to share TX and RX signals on a same antenna. The DDM is aimed

at providing:

TX filtering (noise suppression),

RX filtering (noise suppression),

TX to RX isolation,

front end low noise amplification for the receive chain.

The DDM provides two separate RX paths with four outputs per chain. It also

provides two transmit inputs (two transmit carrier’s capacity). The DDM is used in

a sector basis with one duplexer for main receive path and the other one for diversity

receive path.

4.7.1.1 H2 coupling option

In addition, in order to increase the transmit capacity of the DDM, integrated 2--way

hybrid combiners (H2 coupling) are proposed as an option for the DDM. These

combiners can be by--passed. A front panel switch allows informing the system of

the current DDM H2 configurations (2--way hybrid by--passed or not).

4.7.1.2 VSWR meter option

As an option, the DDM integrates a VSWR meter on both antenna accesses. This

VSWR meter provides three levels of alarms. The corresponding thresholds of

alarms are settable on site, through DDM front panel switches.

The DDM provides a presence detection signal to the ABM. The DDM is also

connected to the ABM through a I2C bus. This bus allows ABM to collect alarms,

inventory information, and to read VSWR thresholds settings.

BTS18000 modules descriptionNortel Networks Confidential 4--43

BTS18000 Reference Manual

The DDM operates on 24V/--48V main power supply through the RICO board. In

addition, the DDM provides the RICO board with:

a DC signal of 3.3V, in order to power supply the inventory circuitry of the

associated SICS (BTS18010) or ECU (BTS18020),

a DC signal of 5V, in order to power supply the associated TXF (VSWR meter

and inventory circuitry).

Table 4--29 DDM specific LEDs behavior

4.7.6 Configuration of the DDM switches for commissioning

Two four--position rotate switches are located on the DDM front panel (see

Figure 4--15).

These switches must be positioned on site:

The hybrid configuration switch (only present on DDM H2) is used to inform the

system about the use of the two 2--way hybrid (by--passed or not).

Table 4--30 gives the switch position meaning.

BTS18000 modules descriptionNortel Networks Confidential 4--47

BTS18000 Reference Manual

The VSWR switch (only on DDMs with VSWR option) allows modifying, on

site, the VSWR meter thresholds on both antenna ports. The three first positions

(positions 0, 1 and 2) are used to offset VSWR thresholds of respectively 0, 2 or 4

dB.

The fourth position (test position) checks that the three LEDs operate correctly.

4.8 Transmit Filter (TXF)

4.8.1 Main functions

The TXF is used, as a complement of the DDM, each time extra transmit capacity

is required without need of receive capacity. It allows direct connection from the

RM PA output to the antenna.

The TXF only filters the signal transmitted from the PA to the antenna and does not

provide the reception path.

The TXF accommodates the same options as the DDM:

H2 coupling,

VSWR meter.
