Features of the SIM Server • Virtual allocation of SIM cards – means very high versatility and avoids expensive and

time-consuming trips for SIM cards replacement and recharging.

• Central store & management. The info from all the SIM cards of all the SIM BOX equipments is stored and managed centrally, on the PC running the Server software application. Later, the relevant info (for a group of modules, valuable for a specified time interval) may be sent to the GSM Gateway (TOPEX multiAccess equipment).

• Simultaneous remote access to the SIM cards

• Flexible SIM cards allocation, according to tariff plans of the mobile carriers (advanced LCR). This way you always get the lowest possible rates for the calls.

• Detailed billing (CDR)

• Different algorithms for SIM selection; flexible SIM timer settings (minute, hour, day)

• A very flexible allocation: at any given moment of time, any SIM may be assigned to any Gateway, no matter where they are in the world

• Group based SIM card management – the user can define a group of mobile modules that will be assigned a group of SIM cards (a base). Any client can have one or several bases of SIM cards.

• Remote administration via IP

• Real time alarming system – the alarms concerning blocked SIM cards or other problems can be sent out via e-mail, SMS or phone. Also, when the user enters the Web based management interface, he will see warning messages.

• Additional local SIM cards can be used for backup. The remote Gateways currently use virtual SIM cards from the server, but they are also fitted with real (local) SIM cards. In case of IP link failure, the Gateway carries on by using the local SIM cards, until the IP connection is restored.

• Automatic SIM insertion / removal detection – the boards with SIM cards are hot swappable, the program scans the SIM BOX to detect the changes (insertion, removal, replacement of SIM cards) and updates accordingly the data base

• Flexible integration into existing GSM Gateways. New mobile cards for the multiAccess gateways include the SIM emulators. Older cards require an addition / replacement: the processor replaced with a piggy-back card. This small PCB includes not only a new processor, but also the required simulation circuits. Also, it features a pair of SIM adapters (miniature PCBs) that you must insert in the last two SIM holders, to emulate the local SIM cards.

• Remote recharging (from the Web interface of the SIM Server) of the pre-paid SIM cards.

• Generates detailed log files. These files can be sent out by e-mail.

1 TOPEX SIM Server DESCRIPTION The structure of the TOPEX equipment is composed from: TOPEX SIM Server, TOPEX SIM BOX and TOPEX multiAccess equipments. The all three equipments are dependent one from another and the operation without one of them is impossible in this configuration. The TOPEX SIM Server equipment acts like a central core of the TOPEX structure. It is a Linux PC which has installed the SIM Server application where through you can manage and configure the all structure of equipments. The TOPEX multiAccess is the GSM Gateway. It contains several mobile modules with attached SIM emulators. Thus every GSM channel can be configured to use the most convenient tariff at a specified moment of time. The TOPEX SIM BOX equipment is a 6U cabinet rack which contains the SIM cards. Single SIM BOX equipment can include up to 512 SIM cards. The TOPEX multiAccess asks for a SIM card to the SIM Server. The SIM Server analyzes the status of the requested SIM card. If the SIM card can be used for a call, the SIM Server communicate with the SIM BOX where the SIM card is physically located. The communication between the three TOPEX equipments is bidirectional.

1.1 Why should I need a SIM Server?

Substantial cost reductions are achieved through the Mobile Gateways from TOPEX (multiAccess equipments) by converting fixed-to-mobile and mobile-to-fixed calls to mobile-to-mobile calls. Optimization is performed both by time using the most convenient route at any given moment and by choosing among different wireless networks, depending upon the called number. The GSM gateways may be distributed in various locations all over the land. It is sometimes difficult to protect the SIM cards from theft.

Moreover, the SIM cards used in gateways are of pre-paid type. When the credit expires, the card must be recharged or exchanged. This means expensive and time-consuming trips to all the locations. While operation, management of debugging of the gateway can be performed remotely via IP, SIM-related problems needed on-site interventions. Such problems include exchanging, recharging of expired cards, repair of defects and so on. But if you use the TOPEX SIM Server system, all these are no longer required! There is no more need to use SIM cards locally in TOPEX multiAccess systems, although SIM cards may be present for backup purposes. Now the subscriber cards can be used centrally, by means of our new Server of SIM card. The SIM data can be supplied over an IP network from one or several secure locations, to all TOPEX multiAccess systems at their various sites in the world.

This way you have several benefits:

• now each mobile channel of every TOPEX multiAccess gateway is generally available to every SIM card at the SIM card server, making possible dynamic SIM card exchanges. Assignments of existing card may can be changed at any time and re-allocated to different GSM channels;

• pre-paid cards can be exchanged without need for “on site tourism” • also, other tasks of SIM card maintenance may be performed remotely, from anywhere

in the world, via the Web interface of the application running on the SIM Server. • very good protection against theft, the SIM cards are in SIM BOX equipments in secure

locations, not physically present in the remote gateways.


TOPEX S.A. Page 6

1.2 Principles of operation of the TOPEX SIM Server

• All of the SIM cards used are virtually stored and operated in a single central “SIM server”

• The SIM Server allocates the SIM cards remotely, via an IP connection • The GSM/UMTS modems from the TOPEX gateways (multiAccess equipments) have

access to the remote SIM via a GSM terminal adapter / SIM emulation device.

2 SYSTEM ARCHITECTURE The TOPEX SIM Server system consists of:

• central SIM Server, that manages all the SIM BOX equipments and the Gateways. The Server program is an application that runs on a highly reliable Linux PC

• the remote gateways (multi-Access equipments) with emulation capabilities – each mobile module of the remote gateway includes a hardware and software SIM emulator.

• one or several SIM BOX equipments, each with several SIM boards (SIM2PCIs up to 16)

Figure 1. TOPEX SIM Server architecture

All these elements are connected via IP (the big Internet) as shown in the drawing above.

To ensure continuous operation, it is highly recommended that you use uninterruptible supplies (UPS) for powering both the remote SIM BOX equipment and the SIM Server computer.

Warning! Use only the equipments shipped in the TOPEX package! Do not try to use other components even if they seem to operate in the same circumstances. For example do not use a simple Linux PC other than the TOPEX SIM Server equipment.


TOPEX S.A. Page 8

2.1 TOPEX SIM Server The administration component of the TOPEX system is a Linux PC named TOPEX SIM Server. It manages every TOPEX SIM BOX and TOPEX multiAccess equipments, no matter where they are located in the world. Any SIM card from any SIM BOX may be assigned to any GSM channel of any TOPEX gateway (multiAccess equipment) that features a SIM emulator. The SIM server equipment has a compact design; it is reliable being enclosed in a 2U height case.

Figure 2. TOPEX SIM Server – General View

2.1.1 Functional description For reliability purposes, the SIM Server makes use of a RAID system that always performs backups of the SIM cards data bases, log files and software application. Its main features are:

• Linux PC

• SIM card management via IP from one central location.

• SIM-Server Database.

• Advanced least cost routing (LCR) functions.

• Management software and remote administration console via TCP/IP.

• User shell for SIM-card management (selection of SIM assignment algorithm, registering and deregistering of SIM cards, monitor function, history, automatic substitution of blocked SIM cards or SIM cards without charge contingent, simulation of card movement, cost-balancing).

• The physical movement of SIM cards is simulated by different algorithms that assign for specified GSM modules various SIM cards, located in different places.

• The number of SIM BOX equipments and Gateways managed is limited only by the processing power of the PC and the bandwidth of the Internet connection (you need a thick pipe).

TOPEX S.A. Page 15

F. Modules card – subscriber unit for mobile network connection

The mobile interface card assures the connection to a mobile network (GSM / CDMA /UMTS).

It contains two modules (wireless modems) on the printed circuit card. There are three types of cards, for GSM, CDMA or UMTS networks. Furthermore, the mobile interface card can be equipped with modules for different frequency bands, such as GSM 900/1800 MHz, GSM 850 MHz, GSM 800/1800/1900 MHz, CDMA 450/800/1900 MHz respectively UMTS 2100 MHz.

In this picture you can see a drawing of the card, with GSM modules.

Inside each mobile module, there is a 4-slot adapter (holder) for the SIM or RUIM cards, if your network operator uses subscriber cards.

Also, each mobile module features a connector for its external antenna. The SMA connector is located on the front panel. On the connector you may thread directly the discreet antenna or a cable to connect to external antennas, directly or through a splitter / concentrator.

On the front panel there are also nine optic indicators for the mobile modules card (four LED indicators per each mobile module and one general).

The significance of these LED indicators is shown in detail in the tables below.

Note: If there is no serial communication between the main processor card and the module card, after a delay of about 15 seconds the reset of this card will be triggered.

2.2.3 Mobile antennas A. Individual antennas

The TOPEX equipment uses different types of individual (discreet) or collective antennas. There are available stick antennas to be threaded directly to the output of wireless modules, Yagi high-gain antennas to be used with the splitter/combiner, or magnetic-base antennas (see details below).

If you use one antenna per each mobile module (GSM / CDMA / UMTS), the recommended type is the “magnetic antenna” described below. These have a connection cable and a base with a magnet for fastening to a ferrous support. The base is heavy, so the antenna will stand upright even if you place it on a flat surface that is not metallic.

Type: “magnetic antenna” Directivity: omni directional Frequency: Multiple bands - 890 to 960, 1710 to1880, 1850 to 1990 MHz and 2100 MHz Gain: 2 dbi Polarization: vertical Height: 72,5 mm total, 43mm effective Cable: RG174, length 2,5m Connector: SME female Magnetic base: diameter 2,8 cm


TOPEX S.A. Page 17

B. Common / combiner splitter

TOPEX provides several types of combiners for using one antenna for several mobile channels. See below illustration and explanations for the 32-way combiner/splitter. It allows grouping of up to eight RF modules on a single high-gain remote antenna. Its banks depend on of the variant of equipage providing a total of 32 cellular channels, so you may use only 4/2/1 external antennas for all of the mobile channels of the TOPEX multiAccess equipment!

This means an easy way to use it and simple installation. The combiner saves both mounting space and RF connecting cables. The high-gain,

directional (Yagi) antennas can be mounted on the roof, for better field strength, and pointed towards specific base stations of the wired network provider.

Our splitter-combiner features four banks (A, B, C, D) with eight RF inputs each, labeled as A1 …A8, B1 … B8, C1 … C8 and D1 …D8 respectively.

The outputs of the wireless modules on the UABxxx cards of the TOPEX multiAccess GSM gateway must be connected to these inputs, as shown in the image to the right. Remember that all wireless modules connected to one bank of the splitter will go out through the same external antenna.

Example: (the 4/32 variant) The outputs of the splitter-combiner marked A, B, C and D, are located at the back of the unit.

The combiner is a rugged, reliable unit intended for mounting inside the 19” rack, as shown in the image to the left.

Alternately, you may simply place the box of the splitter on top of the multiAccess equipment.


TOPEX S.A. Page 18

Its wide pass band characteristics (from 800 MHz up to 2.100 MHz) allow the combiner

to be used with a wide range of the wireless mobile modules (dual band or triple band, 800/850/900/1800/1900/2100 MHz).

The TOPEX combiner/splitter is completely passive equipment, consequently it requires no additional power supply.

In Linux enter the following command to access the TOPEX SIM Server equipment:

ssh tpxadm@<IP address of TOPEX SIM Server>

When you use Putty make the settings according to the Figure 8.

Figure 8: Ethernet connection through Putty

In the Putty main window press check the SSH option, insert the IP address of TOPEX SIM Server, insert the number of port “2212” and press the “Open” button in order to access the TOPEX SIM Server. The authentication data required for the login are:

- SSH port – 2212;

- User name – “tpxadm”;

- Password – “u53rp455”.

The direct connection as root is not allowed. You must enter to the prompt the “su -” command after you are logged in, and insert the “5y5t3mp455” password. The firewall is open by default.

For the serial connection use a serial cable which is inserted in the DB9 connector from the back panel of the TOPEX SIM Server enclosure and in the serial connector from a PC.

Use the HyperTerminal from Windows with parameters 115.200, 8, N, 1 in order to establish a serial communication with the TOPEX SIM Server.


TOPEX S.A. Page 37

4.2 Configuration of multiAccess equipment

The GSM Gateway – TOPEX multiAccess is independent configured from the TOPEX SIM Server equipment. Also the TOPEX SIM BOX equipment is independent configured from the other two TOPEX equipments. You can configure the TOPEX SIM BOX and the TOPEX multiAccess equipments and then the TOPEX SIM Server equipment but the order is random. 4.2.1 Accessing LINUX system console, verifying and modifying IP address of

the multiAccess

To access LINUX system console, you can use a serial connection (local) or a serial emulator through the Ethernet connection.

A. In case of using serial connection, plug the serial cable into the serial connector (COM2

port) of the PG card.

The manufacturer recommends you to turn off your computer before connecting the serial cable to it. A proper functioning of TOPEX multiAccess requires this operation.

You must use a serial communication program (terminal emulator). This may be “HyperTerminal" under Microsoft Windows, Minicom from Linux, TERM95 under MS-DOS etc.

The communication parameters for the serial link are 19200, 8, N, 1:


TOPEX S.A. Page 38

Baud rate: 19200 bps Data bits: 8 Parity: none Stop bits: 1 Flow control: none

Once the connection to the multiAccess gateway is open, press ENTER. You should see the window below that asks you for the login name and password. Enter name “root” and password “91qwerty19”:

If the connection was successful, the window below shows up. If you do not see the "login" cursor, you must wait until it will show up again (usually the delay is of maximum 60 seconds) to repeat the login procedure.

After connecting to the TOPEX gateway, you may use Linux commands for navigating through the directory structure of the TOPEX system.


TOPEX S.A. Page 39

B. In case of using an Ethernet connection, you can use a remote connection to the TOPEX equipment. This is done by “ssh” from Linux or using a program that performs ssh under another operating system (for instance Putty).

[Secure Shell (SSH), also known as Secure Socket Shell, is a command interface and protocol for getting secure access to a remote computer. To ensure this secure access ssh commands are encrypted and secure in several ways: both ends of the client/server connection are authenticated using a digital certificate, and passwords are protected by being encrypted.]

In Linux, you enter the following command to connect to the multiAccess gateway: ssh gsmgw@< IP address of TOPEX gateway>

When using Putty the connection is done as shown in the window below:

Use these parameters when you achieve an Ethernet connection: - for SSH connection : the used port is 2222

- for user name “gsmgw” : the password is “5tgb4rf”

- for “root”: the password is “ 91qwerty19” available only for privileged users

Note: For security reasons, the direct login as „root” can be performed only from those terminals that are included in the list of „secure” (trusted) terminals. From terminals that are not included in this list log-in can be done only indirectly, by log-in as a non-privileged user and going into root mode with the command su followed by the root password.

In a Linux system, privileged user is the system or network administrator, who has access permission above those of an ordinary, non-privileged user. Direct access to root is available only for privileged users]

Remember that the terminal on COM2 serial port is included in the list of trusted terminals, while the pseudo-terminals used by ssh are not on this list.


TOPEX S.A. Page 40

The network settings are located in two different files: one for the equipment settings and

one for the gateway settings. The IP Address and the Netmask of the multiAccess are in the eth0 file.

To see and to modify the IP address of the multiAccess, you must follow next steps: • change the directory typing "cd /etc/sysconfig/"

• to see or to modify the content of file named eth0, use vi editor, typing command vi eth0 like in the image bellow

• if you want to modify some information in this file, you must switch the editor in edit mode by typing the I key.

The editor starts in its command mode. To enter the “edit mode” of the editor you must press “i”. To return to “command mode” press “ESC” key.

To delete an entire line go to “command mode” and press “dd” while the cursor is on line you want to delete.

To delete a single character goes to “command mode” and press “x” after having placed the cursor on the character you want to delete. The first character at the right of the deleted character will be moved over the cursor.

To change the IP address of the TOPEX equipment and the network mask just type in the command line:

<IP Address of the multiAccess> <Netmask>

For example the following IP address and Netmask

192.168.244.5 255.255.0.0


TOPEX S.A. Page 41

Move the cursor at first character in the line. You type "i" to go to the "edit mode”. (You may exit from this mode by pressing the "ESC" key). After that type "ENTER".

If you want the multiAccess equipment to be configurable via Internet you must de-comment (activate) the line shown below by removing the “#” character from the beginning of the line. Remember to change the IP address to that of the gateway of your local network:

# GATEWAY=192.168.1.1 The de-commented line should look like it is shown below. Of course, your gateway

address could be different: GATEWAY=192.168.1.1

Note: It is highly recommend that you make a backup copy of this file to edit it safely. For example you type at the command line: "cp eth0 eth0copy" or "cp eth0 eth01”.

Be very careful when you make changes in the eth0 file. A single incorrect (misplaced) character may cause the multiAccess system to stop working after restart. It is recommended that you only change the numbers of the IP addresses and of the netmask.

• save the modifications using command wq! • restart the TOPEX multiAccess equipment using command /sbin/reboot

7 GLOSSARY ACD – Acronym for Average Call Duration - the average of duration for all the calls made by a subscriber. It is expressed in minutes.

ASR – Acronym for Answer Seizure Ratio – It is calculated by taking the number of successfully answered calls and dividing by the total number of calls attempted (seizures). Since busy signals and other rejections by the called number count as call failures, the calculated ASR value can vary depending on user behavior.

CAS – Acronym for Channel Associated Signaling - It is a form of digital communication signaling. As with most telecommunication signaling methods, it uses routing information to direct the payload of voice or data to its destination.

With CAS signaling, this routing information is encoded and transmitted along the same link as the payload itself. This results in lower available bandwidth for the payload, normally reducing a 64 Kbit/s DS0 to 56 Kbit/s. Because of this, and the inherent security benefits of separating the control lines from the payload, most current telecom systems rely more on the out-of-band signaling.

CDMA – Acronym for Code Division Multiple Access - Advanced communications technology that is a driving force behind 3G wireless networks around the globe. CDMA technology was invented and is promoted by QUALCOMM. It employs analog-to-digital conversion (ADC) in combination with spread spectrum technology. Audio input is first digitized into binary elements. The frequency of the transmitted signal is then made to vary according to a defined pattern (code), so it can be intercepted only by a receiver whose frequency response is programmed with the same code, so it follows exactly along with the transmitter frequency. There are trillions of possible frequency-sequencing codes, so CDMA communication is highly reliable, very difficult to intercept or jam. Because each carrier can be distinguished from the others by means of a specific modulation code, this makes possible the reception of signals that were originally overlapping in frequency and time. Thus, several transmissions can occur simultaneously within the same bandwidth, with the mutual interference greatly reduced by the degree of orthogonality of the unique codes used in each transmission. CDMA ensures excellent quality of voice signal, without noise or interferences, high rate of data transmission and permits a uniform distribution of energy in the emitted bandwidth. UMTS makes use of the W-CDMA technology, wideband CDMA.

DTMF – Acronym for Dual Tone Multiple Frequency - also known as "touch tone". Advanced method for dialing a number, instead of the older Pulse mode. When you press a key on the keypad a combination of two audio frequencies is sent on the line. DTMF capability is important because it allows access to a wide range of interactive voice applications.

E1 - European format for digital transmissions, equivalent with North-American T1. E1 has a data rate of 2,048 Mbps, containing 32 channels with 64 Kbps on each of them, and includes two reserved channels for signaling and control. The North-American T1 standard has 24 channels with 64 Kbps obtaining a data rate of 1,544 Mbps. The E1 and T1 line can be interconnected for international use.

Ethernet - Standard for wired computer networks. Ethernet networks are connected by cables and hubs, and move data around. For wired connections, TOPEX SIM Server provides Ethernet one 10/100 port.

GSM – Acronym for Global System for Mobile Communication - is a digital mobile telephone system that is widely used in Europe and other parts of the world. GSM uses a variation of Time Division Multiple Access (TDMA). GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot. The frequency bands used by the GSM mobile phones are: 400, 850, 900, 1800 and 1900 MHz. The most used are GSM 900 and GSM 1800.

H 323 - An umbrella recommendation from the ITU-T that defines the protocols to provide audio-visual communication sessions on any packet network. It is a part of the H.32x series of protocols which also address communications over ISDN, PSTN or SS7. H.323 is commonly used in Voice over IP (VoIP, Internet Telephony, or IP Telephony) and IP-based videoconferencing.

H.323 was originally created to provide a mechanism for transporting multimedia applications over LANs but it has rapidly evolved to address the growing needs of VoIP networks. One strength of H.323 was the relatively early availability of a set of standards, not only defining the basic call model, but in addition the supplementary services, needed to address business communication expectations. H.323 was the first VoIP standard to adopt the IETF standard RTP to transport audio and video over IP networks.

IMEI - Acronym for International Mobile Equipment Identifier. 15-digit number that uniquely identifies an individual mobile terminal wireless device. The device may be a phone, a data terminal, a modem module, etc. The IMEI code consists of TAC (Type Approval Code) that describes the type of the mobile device, FAC (Final Assembly Code) related to final assembly, SNR (Serial Number) which is unique, and a spare digit. Note that while IMSI is subscriber-related, the IMEI is equipment-related. IMEI is world-wide specific for a certain mobile terminal (phone or modem).

IMSI - Acronym for International Mobile Subscriber Identity. Unique code number (for all the world) that identifies a mobile subscriber (its SIM card) to the network. 15 digit code, contains information about the module code for the country, the network, identification number for the mobile station (subscriber). Linked to the user account information at the network operator. IMSI resides in the SIM card. While IMEI is related to the mobile phone GSM/UMTS module, the IMSI code is related to the SIM.

IP - Acronym for Internet Protocol. It is the protocol from TCP/IP that directs the way data is sent from one computer to another on the Internet. The messages are divided into data packets, routed from the sender network to the receiver network and there re-assembled in the right order to re-create the original message. Because a message is divided into a number of packets, each packet can, if necessary, be sent by a different route across the Internet. These data packets can arrive in a different order than the order they were sent in. The Internet Protocol just delivers them. It's up to TCP protocol (Transmission Control Protocol) to put the packets back in the right order.

IP Address - Short from Internet Protocol address. The numerical address of a network device or resource as expressed in the format specified in the Internet Protocol (IP). In the current addressing format, IP version 4, the IP address is a 32-bit (4 bytes) sequence divided into four groups of decimal numbers separated by periods ("dots"). Each number can be zero to 255. These four groups of numbers look like “127.0.0.1” or „213.154.120.170”. The four numbers in an IP address are used in different ways to identify a particular network and a host on that network.

ISDN – Acronym for Integrated Services Digital Network - Worldwide digital network providing high-speed connection between the terminal devices (telephone, fax machines, computers) for a wide range of telecommunication services, using the existing telephony infrastructure.

LAN – Acronym for Local Area Network - computer network that spans a relatively small area. A group of computers, workstations and associated devices that share a common communications line or wireless link and are located in a relatively limited area, typically inside the same office building. The communications link that interconnects these computers allows any device of the network to interact with any other from the same network. The devices that compose a local network (workstations, personal computers and peripherals) are called nodes and typically share the resources of a single processor or server. This server has resources (applications, processing and data storage capabilities) that are shared in common by multiple computer users. The LAN can be connected to other local networks over any distance via phone


TOPEX S.A. Page 48

lines, wireless links or other connections, and the system of LANs connected in this way is called a wide-area network (WAN).

LCR – Acronym for Least Cost Routing - Refers to the method for delivering calls according to the lowest cost carrier. Often more than one carrier can compete to deliver a call and depending on their relative charges, the equipment will connect the call via the cheapest carrier. This process means searching for the optimum traffic routes via one or several traffic routings enabling a cost reduction.

PBX - Acronym for Private Branch eXchange. The PBX is a small, enterprise version of the larger central switching office of the phone company. A PBX is a private telephone switch. It is connected to groups of trunks (junctions) from one or more central offices and to all of the telephones at the location (subscribers, local extensions) served by the PBX. Current exchanges are in fact PABX, automated PBX, which don’t require a human operator to route the calls.

PCB – Acronym for Printed Circuit Board - Are used to mechanically support and electrically connect electronic components using conductive pathways, or traces, etched from copper sheets laminated onto a non-conductive substrate. Alternative names are printed wiring board or PWB or etched wiring board. After populating the board with electronic components, a printed circuit assembly (PCA) is formed. PCBs are rugged, inexpensive, and can be highly reliable. They require much more layout effort and higher initial cost than either wire-wrapped or point-to-point constructed circuits, but are much cheaper, faster, and consistent in high volume production.

PCM – Acronym for Pulse Code Modulation - is a digital scheme for transmitting analog data. The signals in PCM are binary; that is, there are only two possible states, represented by logic 1 (high) and logic 0 (low). This is true no matter how complex the analog waveform happens to be. Using PCM, it is possible to digitize all forms of analog data, including full-motion video, voices, music, telemetry, and virtual reality (VR).

PIN – Acronym for Personal Identification Number - A secret shared between a user and a system that can be used to authenticate the user to the system. Typically, the user is required to provide a non-confidential user identifier or token (such as a banking card) and a confidential PIN to gain access to the system.

PUK – Acronym for PIN Unlock Code - PUK is the code required to unlock a GSM SIM card that has disabled itself after an incorrect PIN code was entered three times in a row. If an incorrect PUK code is entered 5-10 times, the SIM card will permanently block (disable) it.

RUIM (or R-UIM) - Acronym for Re-Usable Identification Module, is a removable ID chip for cellular phones made for the Code Division Multiple Access (CDMA) network. The RUIM card holds a user's personal information such as name and account number, cell phone number, phone book, text messages and other settings. The RUIM card provides flexibility to switch phones by simply removing the RUIM card and slipping it into another card-enabled phone.

RAID – Acronym for Redundant Array of Independent Disks - a category of disk drives that employ two or more drives in combination for fault tolerance and performance. RAID disk drives are used frequently on servers but aren't generally necessary for personal computers.

SIM – Acronym for Subscriber Identity Module - A subscriber identity module is a smart card that securely stores the key identifying a mobile phone service subscriber, as well as subscription information, preferences and text messages. The equivalent of a SIM in UMTS is a Universal Subscriber Identity Module (USIM). The SIM stores network state information such as its current location area identity (LAI). If the handset is turned off and back on again it will take data off the SIM and search for the LAI it was in. This saves time by avoiding having to search the whole list of frequencies that the telephone normally would. Each SIM is uniquely identified by its ICCID [International Circuit Card ID].

SMS – Acronym for Short Message Service - Means the transmission of short text messages to and from cellular phones. The messages must be text only (no images or graphics) and not longer than 160 alpha-numeric characters. Operators of Mobile Phone Networks use a spare


TOPEX S.A. Page 49

data channel to send SMS messages. You may send SMS messages to another mobile subscriber, the mobile operator can send you phone settings over-the-air or commercial companies may send dedicated content to your mobile terminal.

SS7 – Acronym for Signal System 7 - is a global standard for telecommunications defined by the International Telecommunication Union (ITU) Telecommunication Standardization Sector (ITU-T). The standard defines the procedures and protocol by which network elements in the public switched telephone network (PSTN) exchange information over a digital signaling network to effect wireless (cellular) and wire line call setup, routing and control. The ITU definition of SS7 allows for national variants such as the American National Standards Institute (ANSI) and Bell Communications Research (Telcordia Technologies) standards used in North America and the European Telecommunications Standards Institute (ETSI) standard used in Europe.

SSH – Acronym for Secure Shell or Secure Socket Shell - is a command interface and protocol for getting secure access to a remote computer. To ensure this secure access ssh commands are encrypted and secure in several ways: both ends of the client/server connection are authenticated using a digital certificate, and passwords are protected by being encrypted.]

TCP/IP – Acronym for Transmission Control Protocol / Internet Protocol. It was established by the Defense Department of the USA for communications between computers. It has been at first incorporated in Unix operating system but has become the de facto standard for data transmission via networks, including for Internet. Currently TCP/IP is the basic communication language or protocol of the Internet, but it can also be used as a communications protocol in private network. TCP/IP uses the client/server model of communication in which a computer user (a client) requests and is provided a service (such as sending a Web page) by another computer (a server) in the network. TCP/IP is a two-layer program. The higher layer, Transmission Control Protocol, manages the assembling of a message or file into smaller packets that are transmitted over the Internet and received by a TCP layer that reassembles the packets into the original message. The lower layer, Internet Protocol, handles the address part of each packet so that it gets to the right destination.

UMTS – Acronym for Universal Mobile Telecommunication System - represents an evolution in terms of capacity, data speeds and new service capabilities from second generation mobile networks. A key member of the global family of third generation (3G) mobile technologies identified by the ITU, 3G/UMTS offers mobile operators significant capacity and broadband capabilities to support greater numbers of voice and data customers - especially in urban centers - plus higher data rates at lower incremental cost than 2G.

VoIP – Acronym for Voice over Internet Protocol. It realizes the voice calls routing over the Internet or over any network based on the IP protocol, even in the local networks. Two principal standards are available for the VoIP technology: SIP (Session Initiation Protocol) and H.323. VoIP achieves the voice signal conversion from a standard phone into a digital signal which is sent over the Internet. If you call a standard telephone, the digital signal is reconverted at reception into a voice signal. VoIP allows calls directly from a PC, from an IP phone or from a standard phone using a special adapter.

WAN - Acronym for Wide Area Network. A system of LANs, connected together. A WAN is a network that connects computers located in separate areas, (i.e., different buildings, cities, countries). The Internet is a wide area network.
