Safety and Regulatory Information, Standards and Regulations

Exposure to Radio Frequency Signals (SAR)

Your wireless phone is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission limit for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the US government and Canada. These limits are part of comprehensive guidelines and established permitted levels of RF energy for the general population. These guidelines are based on the safety standards previously set by both US and international standard bodies.

These standards include a substantial safety margin designed to assure the safety of all persons, regardless of age and health.

The exposure standards for wireless mobile phones employs a unit of measure known as the Specific Absoption Rate, or SAR. The SAR limit set by the FCC and Canada is 1.6W/kg averaged over one gram of tissue.

Tests for SAR are conducted using standard operating positions specified by the FCC with the phone transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the phone while operating can be well below the maximum value. This is because the phone is designed to operate at multiple power levels.

Before a phone model is available for sale to the public, it must be tested and certified to the FCC that it does not exceed the limit established by government-adopted requirement for safe exposure. The tests are performed in positions and locations (for exampe, at the ear and worn on the body) as required by the FCC for each model. Th e highest SAR value f or this phone when tested for use at the ear is 0.076W/kg, and when worn on the body is 0.018Wkg. (Body worn measurements differ among phones depending upon available accesories and the FCC requirements.) While there may be differences between the SAR levels of various phones and at various positions, they all meet the government requirement for safe exposure.

For body worn operation, to maintain compliance with FCC RF exposure guidelines, use only Ascom approved accessories. When carrying the phone while it is on, use only the specific Ascom belt clip that has been tested for compliance.

Use of non-Ascom-approved accessories may violate the FCC RF exposure guidelines and shoud be avoided.

The FCC has granted an equipment authorization for this Ascom 9p23 phone with all reported SAR levels evaluated as in compliance with the FCC RF emissions guidelines. SAR information on this 9p23 phone is on file with the FCC and can be found under the Display Grant section of http://www.fcc.gov/oet/fccid after searching on FCC ID 04M9p23.

Safety and Regulatory Information, Protection against Electrostatic Discharge (ESD)

CHAPTER 3 Protection against Electrostatic Discharge (ESD)

3.1 General

Integrated circuits are sensitive to ESD. To avoid damage caused by ESD, service engineers and other people must handle equipment and

boards carefully. Electronic equipment has become more resistive to ESD, but we see an increase of situations

where static electricity can build up. This is caused by an increasing application of man–made fibers like nylon, acrylic, etc. which are capable of generating ESD of 10,000 Volts and more. Walking across a nylon carpet, even for a few feet, could cause a person to be charged–up to more than 10,000 V olt s. Under these conditions, if a system board or a (C)MOS device is tou ched it could easily be damaged. Although the device may not be totally defective, it is often degraded, causing it to fail at a later date without apparent reason.

To make sure that equipment and parts are well protected during shipment, special packaging materials are utilized. System boards will be shipped in anti–static bags and (C)MOS devices and other sensitive parts in small shielded boxes.

3.2 ESD Handling

In the interest of quality and reliability, it is advisable to observe the following rules when handling system boards and parts.

1. Service personnel should ground themselves by using a wrist strap when exchanging system boards in a cabinet.

2. Keep system boards and sensitive parts in their protective packaging until they are needed.

3. When returning system boards or parts like EEPROMS to the factory, use the protective packaging as described.

4. Never underestimate the damaging power ESD can have and be especially careful when temperatures are below freezing point and during very warm weather in combination with low humidity. Make sure that the environmental conditions remain within the limits specified in Section 3, "Product Specifications" in this book.

System Description, Introduction

CHAPTER 1 Introduction

The DCT1900 system is a pico–cellular, digital cordless telephone system that can be connected to a PBX or a Mobility Server via T1 or E1 links or standard analog ports. It is a PWT radio access system, and as such enables the user of the Portable Telephone to make and receive telephone calls anywhere in the area covered by the system.

The system consists of a RE connected to the PBX/Mobility Server, several Base Stations and Portable Telephones. The coverage is established by means of a pico–cellular network consisting of a number of Base St ations conn ected to the RE. By me ans of h andov ers fro m pico–cell to pico –cell, th e user can ro am within the covered area while maintaining the call without degradation of quality. Built–in voice encryption and phone authentication ensures privacy and secure communications.

All functions that are available on a normal wired analog telephone connected to the PBX are also available on the DCT1900 Portable Telephones when connected using an analog or T1 interface. The Portable Telephone will provide digital desk set features when connected to the PBX when using the Digital Link Unit (DLU).

The Freeset system is also capable of sending short messages to the portable display using the TAP interface to a server running a dedicated software application or a compatible messaging unit.

The DCT1900 system is based on digital cordless transmissions between the Base Station and the Portable Telephone. Speech encoding is done in the RE and Portable Telephone, using 32 kbit/s ADPCM. The radio transmissions between the Base S t ation and Port able Telephone use multiple carrier TDMA. Full duplex operation is achieved by using TDD.

One of the basic features of the system is the decentralized DCA technique, by which each Portable Telephone selects the best available speech channel. With DCA, channel selection is not limited to the moment of call set–up, but continues during the speech connection. DCA provides for optimum voice quality between the Portable Telephone and the Base Station as well as controlling the distribution of available channels per Base Station.

The DCT1900 system can be configured to meet user require ment s with respect to the area to be covered and the number of Portable Telephones to be used. This system has been designed to operate in indoor/ outdoor environments and can support both low as well as high traffic density situations.

In a DCT1900 Standalone environment, the system contains a single RE connected to a PBX. In a DCT1900 Mobility environment, the system contains multiple REs connected to the same telephone

network via a Mobility Server.

CHAPTER 2 System Overview

The DCT1900 system may operate as a standalone system or as a mobility system when used in conjunction with the Mobility Server. Figures 2-1 and 2-2 show an overview of the environments in which the DCT1900 system may be applied.

The DCT1900 Standalone configuration consists of a single RE and its associated Base Stations connected to a PBX. In the standalone configuration the RE will connect towards the telephone network with either analog type trunks or a T1/E1 channel associated signalling trunk. The DLU provides an intelligent interface between the Freeset and a proprietary digital PBX. The DLU emulates a digital phone set of the PBX and allows Freeset users to take advantage of digital phone set features. A DCT1900 Standalone configuration provides for wireless phone service in a simple and cost efficient manner.

Digital Phone Set Features

The DLU supports the following digital phone set features to the Freeset DCT1900 DT620 and

9p23 Portable Telephones:

• Multiple Line Appearance

• Caller Line Identity

• Connected Line Identity

• Redirected Party Number

• Message Waiting Indication

• Transfer

• Conference

• Hold

• Reconnect

• Call Back

• Cancel Call Back

The DCT1900 Mobility configuration provides for one or more REs connected to a Mobility Server, which will then connect towards the telephone network. Large integrated networks of DCT1900 Portable Telephones can be built up using multiple REs and one or more Mobility Servers. The Mobility Server(s) provide the capability of intersystem handovers and roaming. In the case of an intersystem handover, a Portable Telephone user can be on a call while moving from the radio coverage area of one RE to the radio coverage area of another RE without any disruption to the call. In the case of roaming in a DCT1900 Mobility configuration, a Portable Telephone can originate or accept a call in the radio coverage area of any RE. Additional features that the DCT1900 Mobility configuration may support when combined with a compatible PBX are Calling Line ID type displays and message indicators.

DCT1900 features such as phone authentication, encryption, and handover between Base Stations on the same RE apply to either the DCT1900 Standalone configuration or the DCT1900 Mobility configuration. The signalling interfaces that the RE presents towards the phone network are different in the case of a DCT1900 Standalone and a DCT1900 Mobility configuration. Table 2-1 summarizes the signalling differences between the two configurations.

System Description, System Overview

System Architecture

The DCT1900 system provides a wireless infrastructure between the user and the MS/PBX. The system can serve multiple users at the same time.

The system can be split up in a fixed part (made up of one RE and multiple Base Stations) and many Portable Telephones. The basic configuration of a DCT1900 system allows:

z Several systems to provide the same service as one large system. A user with one Portable

Telephone is able to walk around in different areas covered by different systems without interrupting an ongoing call. This feature is known as inter-system handover.

z A user can use the same Portable Telephone in another area or remote site, keeping the same

number. This feature is known as inter-site roaming.

Different aspects of the DCT1900 system are discussed below.

Radio Exchange Synchronization (DCT1900 Mobility Configuration only)

In order to support the inter-system handover capability, REs have to be synchronized. REs are synchronized using a master/slave concept, where one master RE supplies a synchroniza tion signal to a number of slave REs. A slave RE can act as a master for three further slave REs, thus creating a multi level star network with a maximum of two levels, see Figure 2-3.

Slave

Master Slave

Level 1

Level 2

Slave

Figure 2-3 Synchronization Topology

In the master RE, it is possible to select the synchronization source between an internal clock and a T1 or E1 interface to the Mobility Server.

In case the synchronization is lost (e.g. due to cable failure) on a slave RE, the slave will generate an alarm on the Mobility interface to notify the MS. However, the slave will continue to operate and

2-6

System-DCT1900/R8/mw

Technical Product Manual - DCT1900

System Description, System Overview

will still synchronize slaves connected to it, effectively forming a separate "sub cluster" within which seamless handovers are still possible.

The delay in the cable used to synchronize the REs must be measured and entered into each of the slave REs. The accuracy of this delay measurement is very important and must be taken with care.

Registration

Registration entails the Portable Telephone establishing a link with the RE/MS, whereby the Portable Telephone tells the RE/MS who it is, i.e. extension number, system number range, home node number , and the RE/MS authorizes the Port able Telephone to use its resources to make and receive calls.

In the case of a DCT1900 mobility configuration with multiple Mobility Servers:

z If the MS is not the Home MS, then there must be a physical connection (QSIG Tie Line)

between the Home MS and the MS the phone is trying to register to.

z The Portable Telephone’s PUN and authentication key must be known by its’ home MS. z The system number of the RE must be within the system range initialized in the Portable

Telephone.

Start of Registration

Registration starts whenever:

z The Portable Telephone is switched on and sees a system (within the allowed system range). z When the Portable Telephone sees a system with better receive signal strength quality than

the current one which is also in its system range (the Portable Telephone will roam to another system).

z The system asks the Portable Telephone to do so (initiated by the RE/MS). This function

updates databases which may contain corrupted data (e.g. after restart s of system or RE/MS).

Note:

When a Portable Telephone goes out of range and comes back in range of the same RE, the registration procedure will not be repeated.

Registration Successful

If all requirements are met, the registration will succeed. Note that this dynamic behavior means that only at this point will a Portable Telephone be registered in a system. There will never be a fixed relation between a system and a PUN!

Registration Failures

The registration process may result in a rejection from the RE/MS. If the PUN of the Portable Telephone is not initialized in the RE/MS or when the authentication keys in the Portable Telephone and RE/MS are different, the Portable Telephone will be rejected. The result will be that the Portable Telephone will not try again. Only when the Portable T elephone is switched off and on again, or searched by the RE/MS or by the system, will it try to register again.

The process can also fail because of other reasons. For example, when a connection set–up failed or when congestion occurred in a particular Base S tation RE/MS, the registration process will automatically start again after some time.

When a Portable Telephone moves from a RE where it was registered to a new RE and the registration fails on that new RE, it will still be registered in the RE where it came from.

Page 30

Technical Product Manual - DCT1900

System Description, System Overview

De–registration

De–registration is the process where the authorization at registration is removed. Once the user is de-registered, he can no longer be reached. A user can de–register from the RE by switching the Portable Telephone off, or by roaming to another system.

Whenever the RE is not able to inform the MS (e.g. congestion in the MS) about the deregistration, the RE will repeat it every time there is an incoming call for that specific Portable Telephone.

Authentication

The authentication of a Portable Telephone is done during registratio n and at incoming or outgo ing call establishment. It will be executed according to the PWT Standard Authentication Algorithm (PSAA). The algorithm uses the authentication key that is download ed over the programming cable into the Portable Telephone during initialization.

In a DCT1900 Mobility Server configuration for performance reasons, a session key (temporary key, reissued at registration time) will be stored locally in the RE as the result of a registration, to allow authentication without consulting the MS during call establishment.

Inter System Handover (DCT1900 Mobility Configuration Only)

Inter system handover is the capability in a mobility configuration of a Portable Telephone that is handed over automatically to another RE when leaving the coverage area of one RE and moving into a coverage area of another RE. When a user moves to a new RE (refer to Figure 2–2), on request of the MS the old RE will remove the relation between the moved Portable Telephone and the old RE (de–registration) while the new RE adds the relation between it and the Portable Telephone (registration). Handovers from one RE to another can only be achieved when all of the following conditions apply:

z Base Stations of different RE’s meet the PWT specifications. z The REs involved are synchronized. z Both REs have system numbers that fall within the Portable Telephone system range. z The Portable Telephone detects a stronger signal from the new RE than the old RE.

If these conditions are not met, the inter system handover will not be seamless or the call can even be lost when the Portable Telephone tries to move to the new RE.

If two REs operate in overlapping areas, a Portable Telephone may need to choose between an intra system (to another Base Station of the same RE) and an inter system handover. In these situations, the Portable Telephone will prefer an intra system handover. In general, a 6dB signal strength improvement is required for an intra system handover while a 12dB improvement is required for an inter system handover.

Roaming (DCT1900 Mobility Configuration Only)

Roaming is a feature whereby a Portable Telephone moves between two geographically separate but electronically connected MSs with the attend an t REs. Wh en turn e d on in its home covera ge area, the Portable Telephones’ connectivity and functionality is normal. When turned on in the other MS coverage area, the Portable Telephone registers itself as a visitor and this MS communicates with the other MS to let it know that the Portable Telephone is now active on the other RE. Any calls to the Portable’s PUN will then be routed to the new MS to be passed on to the Portable Telephone.

2.2 Roaming and Handover Handling by the Portable Telephone

Sections 2.2.1 and 2.2.2 describe when the Portable Telephone starts internal (intra cell, same Base Station), external (inter cell, another Base Station of the same RE) and inter system handovers (another Base Station of another RE) and location updates (roaming).

2.2.1 Unlocked Situation

When the Portable Telephone is first turned on, it will regularly scan the air interface. As soon as the Portable Telephone detects a bearer signal from a Base Station, it will lock to this bearer. A bearer is an active PWT air interface channel in which transmissions take place. When a Base Statio n is idle (there are no calls routed via this Base S t ation), it transmits a dummy bea rer which is also referred to as a beacon signal. Dummy bearers enable the Portable Telephone to lock on to an idle Base Station and to scan the environment.

If the synchronizing system number is not part of one of the Portable Telephone subscriptions, the Portable Telephone will scan the air interface again.

If the synchronizing system number is part of the system range of one of the Portable Telephone subscriptions, that subscription will be selected and the Portable Telephone will use the bearer as a standby bearer. From this moment on the Portable Telephone will start to collect data concerning the situation in other channels on the air interface. This synchronous situation is described in the paragraphs below.

The Portable Telephone falls back to asynchronous roaming if during a certain period of time no valid frames are received. In this case all collected data concernin g the situati on in other channels is cleared.

To limit the energy consumption during the unlocked situation, the Portable Telephone will go into a sleep mode if it does not find a bearer within 10 minutes. The sleep mode will be interrupted every 2 minutes, when the Portable Telephone performs one full scan to see if there are any systems present.

2.2.2 Locked Situation

Environment Scanning by the Portable Telephone

If the Portable Telephone is locked to a standby bearer, it maintains a list of information for each channel on the air interface. This is called a history list, which contains the following information: RSSI: For each channel, a received "Received Signal Strength

RQI: For each channel with an active bearer or dummy bearer, a

Base Station & System ID: For each channel with an active bearer, the Portable Telephone

Indication" (RSSI) value is stored. For an active bearer, this is an indication of the strength of the received signal. For an idle channel, this is an indication of the noise level.

"Received Quality Indication" (RQI) value is stored. The RQI value is determined by the number of correctly/incorrectly received frames.

will store the identification of the Base Station and RE.

Page 32

Technical Product Manual - DCT1900

System Description, System Overview

System Status

A Portable Telephone contains a list of the current RE status. For each system, the st atus may be: NOT_ALLOWED: The Portable Telephone is not allowed to access this RE. TEMP_NOT_ALLOWED: The Portable Telephone is currently not allowed to access this

ALLOWED: The Portable Telephone is allowed to access this RE.

Roaming

If the Portable Telephone is locked to a certain Base Station, two types of roaming are supported: voluntary roaming, when a better bearer is available, or forced roamin g, when the current bearer is no longer valid. If the Portable Telephone is locked to a RE, it regularly scans its environment. During the environment scan alternative REs are investigated and a bearer set–up may be attempted.

Voluntary Intra System Roaming

Voluntary intra system roaming takes place if the Portable Telephone detects a Base Station of which the signal strength is at least 6dB stronger than the current bearer, and remains at least this amount stronger during a number of consecutive frames.

Voluntary Inter System Roaming

Voluntary inter system roaming takes place when:

z The RE status of the other RE is higher than the system status of the current RE. If the RE

status of the other RE is higher than the RE status of the current RE during a number of consecutive frames, a location update will be started.

z The RE status of the other RE is equal to the RE status of the current RE. If the RE status of

the other RE is equal to the RE status of the cu rrent RE and th e RSSI is at least 12dB strong er than the current bearer RSSI during a number of consecutive frames, a location update will be started.

z The RE status of the other RE is lower than the RE status of the current RE. If, during a

number of consecutive frames, the RE status of the other RE is lower than the RE st atus of the current RE and the RSSI of the best bearer of a Base Station of the other RE is at least 12dB stronger and the Portable Telephone does not see any other Base Stations of this RE and the current Base Station has no further bearers available, the Portable Telephone will start a location update.

RE, but may be allowed to access this RE in the future.

Forced Intra System Roaming

If the current bearer cannot be used any more, the Portable Telephone will immediately try to switch to the best bearer on the current RE.

Forced Inter System Roaming

If the bearers of the current RE cannot be used any more, the Portable Telephone will immediately try to switch to the best bearer of alternative REs.

Handover

During a call, two types of handover are supported again: voluntary handover and forced handover. If there are no problems with the current bearer, the Portable Telephone will investigate alternative bearers during a call. Handling of the forced handover is critical because in this case the speech service is disrupted.

Page 33

Technical Product Manual - DCT1900

System Description, System Overview

Voluntary Intra System Handover

If the best bearer of another Base Station is at least 6dB or better during a number of consecutive frames, the Portable Telephone will start a handover to that Base Station.

Voluntary Inter System Handover

For handovers, only REs with the RE status ALLOWED and TEMP_NOT_ALLOWED are considered as alternatives:

z The RE status of the other RE is equal to the RE status of the current RE. If the best bearer of

a Base St ation of a nother RE is at le ast 12dB or better durin g a number of consecutive frames and there is a bearer free on this Base Station, an inter RE handover will be started.

z The system status of the other system is lower than the system status of the current system. If,

during a number of consecutive frames, the RE status of the other RE is lower than the RE status of the current RE, and the best bearer of a Base Station of the other RE is at least 12dB better and of the current RE no other Base Station is detected and the current Base Station has no other bearers available, then a location update will be started.

Forced Intra System Handover

If the quality of the traffic bearer becomes unacceptably bad, an immediate attempt to find a different bearer is started. This may result in a handover.

Forced Inter System Handover

If a good bearer cannot be found within the current RE, alternative systems will be investigated in the history list. If no RE is found, the Portable Telephone quickly scans its environment to find a valid bearer. If a bearer is found and the network has not yet cleared the call, the Portable Telephone continues to scan its environment. If the network has cleared the call, e.g. because the search took too long, the Portable Telephone will release the call.

2.3 User Functions

The user functions are depending on type of interface between the RE and the connected Telephone Network, and the features supported by the connected Telepho n e Net wo rk.

2.3.1 DCT1900 Mobility Configuration and E1-CAS Standalone when connected to a MD1 10

System Description, Hardware Building Blocks

Message Service (SMS) source. The printer can print a hardcopy of the system error messages. In a multiple system configuration, up to 13 RE’s can be cascaded together.

The RE consists of:

z –One to four Modular Cabinets. The 10 inch Modular Cabinet contain a MCCB and a

backplane with 9 system board connectors, a rectifier circuit and a DC/DC converter.

z –A number of system boards.

The Modular Cabinet requires an external power source of -48Vdc.

3.2 Base Stations

The Base Station enables radio communications between the RE and Portable Telephones. The Base Station has two main functions:

z To modulate a carrier with the digital encoded information (TDMA frame directed to Portable

Telephone),

z To demodulate a modulated carrier (TDMA frame received from Portable Telephone).

A Base Station communicates with the RE via two (2B+D) interfaces, requiring two twisted pair cables. The two 2B channels (256 kbit/s) provide eight 32 kbit/s speech paths between a Base Station and a RE, enabling a Base Station to handle eight simultaneous calls. In addition to data communication, these two twisted pairs are also used to distribute power to the Base Stations. One or two additional pairs can be wired to provide a longer powering distance.

Two methods exist to power Base Stations:

z Via local power supply. z Via Modular Cabinet.

With the first method, Base Stations are powered by -48Vdc which is not routed via the cabinet. The maximum cable length between Base S t ation and RE is only data limited and may reach up to 11,500 ft.

With the second method, power is distributed via the Modular Cabinet and Base Station cabling. The cable length between the Base Station and cabinets now depends on the number of twisted pairs used for power, the type of cable and environmental noise.

The number of Base Stations used in a system depends on the area to be covered and the traffic density. Typi cal in–house coverage is a 100-200 ft. radius. The cell size may vary between 40 ft. indoors and up to 1,000 ft. outdoors.

The air interface conforms to PWT MAC Layer and FCC part 15.

3.3 Portable Telephones

The Portable Telephone (PT) supports the basic fu nctions of a normal wired DTMF–type telephone. The PT is available in three models: the 9p23, the DT600 and the DT620. Each is equipped with a 3-line 12 character dot matrix LCD display , backlit illumination keypad and display, and plastic keypad. See Section 3, "Product Specifications," Chapter 1, "Portable Telephones" and Chapter 12, "Portable Telephone Accessories" for further information. With the DLU, the 9p23 and DT620 PT will support up to 4 line appearances.

4.6 Digital Trunk Unit - DTU-E1

4.6.1 CCS - REX-BRD0003 or 2/ROFNB 157 13/6

The DTU provides the digital interface between the MS and the RE. The physical connectio n with the MS is established via twisted pair cables.

Every DTU board contains 2 DTCs (see Figure 4-4), each equipped with identical firmware. Both DTCs support the Common Channel Signalling (CCS) interface.

Each CCS interface provides 30 (total 60 per board), communication channels to which Portable Telephones are assigned dynamically. These channels are shared by the Portable Telephones which means that although the RE can handle more Portable Telephones, only 30 calls per CCS interface can take place at the same time. The maximum n umber of Port able Telephones a RE can handle depends on the GOS (grade of service) and the traffic capacity of the RE configuration. However, there is a maximum of 60 concurrent off hooks and a maximum of 1 DTU-E1 card per mobility RE.

CHAPTER 5 Other System Aspects

5.1 Installation and Maintenance

As each DCT1900 system is configured to meet specific user requirements, the RE must be assembled on location. The system must be initialized after the physical installation. DCT1900 system initialization, maintenance and updating, and fault finding and repair are acco mplished with the aid of the CSMW Software program running on a person al computer.

Automatic System Maintenance is a built–in feature that will detect, report, isolate, and when possible, recover the system from errors.

All of the system boards in the RE have a number of light em itting diodes that enable maintenance personnel to quickly localize a faulty board. This feature is applicable during the power–up phase and operational use of the system.

5.2 Statistics

The CSMW software is capable of collecting statistical information. During operational use of the DCT1900 system, useful information can be registered. This information can consist of the total call time of all Portable Telephones per hour during a day or a period of days, highest number of simultaneous calls, call duration per user, distribution of calls according to the call length, load of Base Sta tions, sta tus informa tion of a call, handove rs, etc. All this in formation is useful to an alyze the performance of the DCT1900 system.

Base Station Numbering

Base Stations are ide ntified by hexadecimal number s 08-FF which are referr ed to as Base Station numbers or Base Station identities. A range of eight hexadecimal numbers is assigned to the CLCs of a SLU/CLU when you add the first Base Station to it by means of the CSM software command Base Station–Add. When you add the first Base Station to another SLU/CLU the next free eight hexadecimal numbers are assigned to its CLCs. The first SLU/CLU receives 08-0F, the next SLU/CLU that has a Base Station added will be 10-17. The Base Station assigns Base Station numbers according to the CLC it is physically connected to. CLC 1 correlates to Base Station number 08, or 10, etc.

The hexadecimal numbers 00 to 07 are not used. Therefore th e hexadecimal numbers 08 to 0F will be assigned to the first SLU/CLU used to add the first Base Station. Base S t ation numbering is 08-FF.

Given below is an example:

1. When you define the first Base Station of the first SLU/CLU, its CLCs (1 to 8) will get Base

Station numbers 08 to 0F (hexadecimal).

2. When you define the first Base St ation of th e second SLU/CLU, its CLCs (1 to 8) will get Base

Station numbers 10 to 17 (hexadecimal).

3. When you define the first Base Station of the third SLU/CLU, its CLCs (1 to 8) will get Base

Station numbers 18 to 1F, etc.

If a SLU/CLU board is removed by the CSMW "Remove Board" command , a gap of 8 Base Station numbers may arise. When there is a gap in the numbering, and the first Base station is added to another SLU/CLU, the numbering system described above is used; the numbe rs in the gap are not used. If in such a situation all Base S ta tion numbers are used (08 – FF), th e Base Station numbers of the oldest ”gap” are used.

Note that if there are gaps in the Base St ation numbers, the Base Station numbers will shift after a system reset. If, for example, the second SLU/CLU is removed, then after a system reset the numbers are:

z The CLCs of the first SLU/CLU still have Base Station numbers 08 to 0F z The CLCs of the third SLU/CLU now have Base Station numbers 10 to 17, etc.
