Components Confidea is a wireless conference system offering conferencing facilities over a robust wireless link. Depending on the model, these facilities include discussion, voting and/or language distribution. The delegate units are stand-alone, table top units that wirelessly connect to the Confidea Wireless Conferencing Access Point (WCAP). This Access Point has a built-in web server that allows configuring and monitoring of the system from any PC or laptop with a network card, using a standard internet browser. Depending on the application, Confidea can work as a standalone system, but can also be connected to an existing Televic TCS2500 or TCS5500 system. 4.1.2. Stand-alone system A stand-alone Confidea system offers basic discussion and basic voting or opinion polling (depending on the model) In this case there are no connections to other systems, except for the Confidea WCAP that can be connected to a LAN network for monitoring and configuring. The Confidea access point (WCAP) will in this set-up act as a mini central unit, offering all functionality for a basic discussion and/or opinion polling application. 4.1.3. Connected to Televic wired conference system As part of a wired system, the Confidea offers full functionality such as extended voting facilities and language distribution. When connected to a TCS2500 or TCS9000 central unit, the Confidea set-up becomes an integral part of the wired system
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 17 5. Wireless networks and frequency bands 5.1. Wireless LAN Most of the wireless local area computer networks today are based on the IEEE 802.11 a/b/g standards. These standards were developed by the IEEE (Institute of Electrical and Electronics Engineers) in order to insure inter-operability between different WLAN vendors. Refer to Table 5.1: Wireless LAN standardsTable 5.1 for an overview of the different standards: Table 5.1: Wireless LAN standards 802.11 Standard Release Date Frequency (GHz) Maximum bit rate (Mbits/sec) Modulation type a 1999 5 54 OFDM b 1999 2.4 11 DSSS g 2003 2.4 54 OFDM 5.2. Televic Confidea system The wireless network of the Televic Confidea system is based on the 802.11 a/g standards. Additional protocols have been added on top of the 802.11 a/g standards to provide high robustness against interference from other wireless devices. These additional protocols also ensure a guaranteed quality of service for the audio streams on the wireless network. The Confidea system supports the following frequency bands (refer to Table 5.2): Table 5.2: Frequency bands supported by Confidea ISM 2.4 GHz RLAN low RLAN high ISM 5 GHz 2412 MHz 5180 MHz 5500 MHz 5745 MHz 2417 MHz 5200 MHz 5520 MHz 5765 MHz 2422 MHz 5220 MHz 5540 MHz 5785 MHz 2427 MHz 5240 MHz 5560 MHz 5805 MHz 2432 MHz 5260 MHz 5580 MHz 2437 MHz 5280 MHz 5600 MHz 2442 MHz 5300 MHz 5640 MHz 2447 MHz 5320 MHz 5660 MHz 2452 MHz 5680 MHz 2457 MHz 5700 MHz 2462 MHz 2467MHz 2472 MHz In the 2.4 GHz ISM (Industrial Scientific Medical) band, there are 13 overlapping wireless carriers available. Only 3 non-overlapping carriers are available. In the “RLAN low” frequency band, there are 8 non-overlapping wireless carriers. In Europe all of these wireless carriers can be used. In the USA and Canada (FCC regulations) only the 4 lowest wireless carriers Note: The 2.4GHz and 5GHz frequency bands are license free world wide. However you must be aware of country specific limitations and follow them.
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 18 may be used (5180 MHz – 5200 MHz – 5220MHz – 5240MHz). In the “RLAN high” frequency band, there are 10 non-overlapping carriers. In Europe all of these wireless carriers can be used. In the USA and Canada (FCC regulations) these frequencies cannot be used. In the 5 GHz ISM frequency band, there are 4 non-overlapping carriers. All of these carriers can be used. 5.3. Frequency Planning 5.3.1. Use with WiFi base stations nearby When the CONFIDEA system is set to automatically select the wireless carrier frequency, the COFIDEA carrier frequency will be dynamically set to another channel if other existing WiFi wireless devices occupy the same channel. This dynamic frequency allocation ensures a high robustness of the system even if the frequency occupation changes during the meeting. When the CONFIDEA system is set to manually select the wireless carrier frequency, then you must make sure the CONFIDEA wireless carrier does not overlap the already occupied WiFi wireless carrier channels. 5.3.2. Use of multiple Confidea systems When the CONFIDEA system is set to automatically select the wireless carrier frequency, the COFIDEA carrier frequency will be dynamically set to another channel if another CONFIDEA wireless system occupies the same channel. This dynamic frequency allocation ensures that each CONFIDEA system will be set automatically to different frequencies. When the CONFIDEA system is set to manually select the wireless carrier frequency, you must make sure the CONFIDEA wireless carriers of the different rooms do not overlap each other. Note: When manually setting the CONFIDEA wireless carrier, make sure to avoid channels already occupied by Wireless LANs or other Confidea systems in the area. Note: When manually setting the CONFIDEA wireless carrier, make sure to avoid channels already occupied by Wireless LANs or other Confidea systems in the area.

Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 42 12.2. RF Configuration 12.2.1. General Power Room size: the transmitted output will be adjusted to cover the configured room size. The system will decide the appropriate power setting when the auto setting has been selected Frequency The drop down list box allows you to select the frequency on which the system needs to operate. Auto When the ‘Auto’ setting has been selected, the system will decide automatically on which frequency to operate, based on its measurements of the available spectrum. In this way, interference with equipment that operates nearby is avoided. Frequencies listed in BLACK color. When one of the frequencies is selected out of the list, the system will be forced to work on that frequency and will not automatically switch to another channel should interference occur. Frequencies listed in BLUE color. Some frequencies require a special procedure before equipment can occupy the channel. These frequencies are indicated with a blue color. Compliancy with the ETSI EN301893 standard requires a channel availability check on these special frequencies before one of these frequencies can be used. This also implicates that, although an operating frequency has been manually selected, the system will still switch to another available channel when a radar signal or other interfering signal has been detected on that channel. Frequencies listed in RED color. Some frequencies will be marked in red indicating that an interfering signal was detected on that channel. The interference severity can be monitored in the quality pages. 12.2.2. Quality 2.4 GHz ISM Channel Quality On this webpage the expected quality for each possible RF channel in the 2.4GHz ISM band can be monitored. This visualization of channel availability and quality helps to select a fixed RF channel in case the system is set not to work in automatic mode. 12.2.3. Quality 5.15 – 5.35 GHz On this webpage the expected quality for each possible RF channel in the 5.15-5.35 GHz band can be monitored. This visualization of channel availability and quality helps to select a fixed RF channel in case the system is set not to work in automatic mode. 12.2.4. Quality 5.47 – 5.725 GHz On this webpage the expected quality for each possible RF channel in the 5.47-5.725 GHz band can be monitored. This visualization of channel availability and quality helps to select a fixed RF channel in case the system is set not to work in automatic mode. Note: The channel availability check takes 60 seconds. During that time delegate units cannot connect to the Confidea Access Point
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 43 12.2.5. Quality 5.8 GHz ISM On this webpage the expected quality for each possible RF channel in the 5 5.8 GHz ISM band can be monitored. This visualization of channel availability and quality helps to select a fixed RF channel in case the system is set not to work in automatic mode. Note: From time to time, the Confidea system will also measure its own activity in the channel on which it is currently operating. This results in a RED indication on the corresponding bar graph, but does not affect the reliable operation of the system. Note: The channel availability is visualized using colors: A full GREEN bar indicates the channel is available 100% of the time. This channel is thus safe to use. A full RED bar indicates the channel is fully occupied by other radio devices. This channel should not be used to operate the Confidea system. The more activity on a channel, the more the corresponding bar will color RED, and thus the more likely interference will occur with other systems.
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 44 12.3. Conference Management 12.3.1. General Conference Configuration Maximum Number of Active Microphones: Defines the maximum number of simultaneous active microphones. The system can handle a maximum number of 8 active microphones. Microphone Mode: Defines the conference mode. With Request: Enables the participant to send a request to speak to the chairman or conference operator by pressing the microphone button (or to cancel his request by pressing the microphone button again). Once the floor is requested, the green LED above the microphone button will flash. This means that the conference unit is in request mode. The chairman or conference operator grants the participant the permission to speak by using the NEXT button or by clicking the green microphone on the computer screen in case the Confidea system is connected to a central unit and PC control software is used. While the conference unit is in request, the red signal ring of the microphone will flash. With Request No Clear: Enables the participant to send a request to speak to the conference operator or chairman. However, he cannot cancel his request. The chairman or conference operator grants the participant the right to speak by using the NEXT button or by clicking the green microphone on the computer screen in case the Confidea system is connected to a central unit and PC control software is used. While the conference unit is in request, the red signal ring of the microphone will flash. Direct Access: Enables the participant his microphone to turn on or off at any time. The only limitation here is the maximum number of microphones which may be active simultaneously. FIFO: In this conference mode, only one microphone can be active at a time without intervention of the conference operator. Activation of another microphone switches of the current active microphone. The only exception here is that the microphones of a delegate and the chairman can be active at the same time. Override: Works like the FIFO mode; however multiple microphones can be active at the same time. The number of microphones that can be active simultaneously is set by "Maximum Number of active Microphones" setting. When the maximum allowed number of microphones are switched on, activation of an additional microphone will automatically switch off the microphone that was active for the longest time. Again, the Chairmen units can always be activated, regardless of the number of microphones already switched on. Note: Choosing a high number of active microphones will limit the number of interpretation channels.
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 45 Group 1: Enables one microphone at a time to be active without a request for activation. Other participants can switch their microphone in request mode; the first applicant gets the floor when the delegate who has the floor turns off his active microphone or when the chairman or conference operator grants the participant the permission to talk by using the NEXT button or by clicking the green microphone on the computer screen. Group 2: Enables two microphones to be active at the same time. Other participants can switch their microphone in request mode; the first applicant who requested the floor gets the floor when one of the currently active microphones is turned off or when the chairman or conference operator grants the participant the permission to talk. Group 3: Works exactly like Group 1 and Group 2, with the alteration that three participants can have the floor at the same time. Group 4: Works exactly like Group 1 and Group 2, with the alteration that four participants can have the floor at the same time. Volume: Defines the loudspeaker volume. Interpreter Configuration Defines the number of broadcasted interpretation channels. A maximum of 16 interpreter channels can be set. Note: Although it is possible to select the highest setting of number of active microphones together with the highest number of interpretation channels, it is advised to use the settings that are not marked in red! Note: Choosing a high number of interpretation channels will limit the number of maximum microphone channels. Reference: When using Confidea in conjunction with other Televic conference systems and PC control software, please refer to the User Manual of those systems for more information on the use and setting of the various conference modes. Note: If the Confidea system is connected to a Televic conference system central unit, the conference mode settings will be managed from that central unit.

Encryption 12.5.1. Key Assignment Introduction To ensure a highly secured wireless system, the Confidea system uses an encryption algorithm and mechanism that is fixed and cannot be changed. The information that is sent over the radio link is encrypted with a key to make it inaccessible for 3rd party equipment. This key is default and identical for all Televic units. Security can be increased by adding a custom key, that is specific to a certain set-up or installation. Only the units and access point that share the same encryption key are able to communicate with each other. In this way, the system has become customer exclusive and as a result an even higher degree of security has been reached. Encryption Key Default Key: When selecting this key, information over the wireless link is encrypted, using the Televic default key, used by all Televic equipment Custom Key: To further increase security, or to limit the access to the Access Point only to a well controlled number of delegate units, a custom key can be generated and send to those units that are allowed to join. The result of this action is that only the units that know this key can Caution: Updating of firmware is not without risk and should only be performed by, or under the strict guidance of, qualified personnel.

Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 49 13. Initialization 13.1. Introduction The system can be controlled by the WCAP in stand-alone mode or together with the TCS2500 / TCS5500 Central unit in coupled mode. In stand-alone mode it is not required to initialize the units. However, if you want to authorize the wireless units that will be connected into the system you can follow the unit initialization procedure. In coupled mode, the same initialization procedures have to be followed as defined in the documentation from the central unit. To personalize the system and to further extend the confidentiality of your wireless conference system a unique encryption key can be defined. 13.2. Stand-alone mode 13.2.1. Access modes When you use the Confidea system in stand-alone mode, i.e. with no connection to a TCS2500 or TCS5500 central unit, the WCAP is responsible for the unit initialization and access control. In stand-alone mode, the WCAP supports two kinds of access: open access and controlled access. Open access: This is the default mode. Any unit can connect to the WCAP without authorization procedure Controlled access: a unit can only connect after going through an initialization and authorization procedure. 13.2.2. Selecting the Access Mode To select the desired access mode go to the “Init Units” sub tab in the “Conference Management” menu from the web server (refer to Figure 13.1) Figure 13.1: Web server init page selection The following screen will appear: Figure 13.2: Unit init page
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 50 To select ‘Open Access’ click the radio button next to ‘Open Access’ on the ‘Init Units’ page (refer to Figure 13.3) Figure 13.3: Init units page - Open access Select this mode if the wireless units are not required to be authorized, before they are allowed to connect with the WCAP. This mode is especially useful for a fast setup. To select ‘Controlled Access’ click the radio button next to ‘Manual’ on the ‘Init Units’ page (refer to Figure 13.4) To control which wireless units connect with the WCAP a manual initialization of the units is required. Figure 13.4: Init units page - Manual 13.2.3. Unit initialization in ‘Open Access’ mode Switch on all wireless units and wait a few seconds until the units have discovered the WCAP (see chapter xxx) All active wireless units will automatically connect with the WCAP and join the conference. 13.2.4. Unit initialization in ‘Controlled Access’ mode In this mode, a manual initialization is required. The manual initialization procedure requires the use of the 3 buttons on the web server displayed above: “Start Init”, “Save and Stop Init” and “Clear Init List”. Take the following steps to initialize all units: 7. Switch on all wireless units and wait a few seconds until the units have discovered the WCAP (see chapter xxx) 8. Select the “Clear Init List”, , to clear any previously created initialization list. 9. Start the new initialization by selecting the “Start Init”, ,button. After you started the new initialization, the LED’s on all wireless units will start to blink. 10. To add a unit to the initialization list, press the microphone button of the unit to add. 11. The LEDs will go out indicating that the unit has been added to the list. 12. Repeat step 3 for each unit that needs to be added. 13. When finished, stop and save the initialization by pressing the “Save and Stop Init” button,. Note: Avoid using Open Access in areas with more than one active Confidea system, as there is no control over which WCAP the delegate units will connect to.
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 51 Only the units that are have been initialized and listed in the Init List will now be able to join the conference. The init list is stored in the WCAP and stays in memory even after switching the WCAP off. Next time the WCAP and delegate units are switched on, only these units that are in the Init List will be allowed to connect to the WCAP. 13.2.5. Adding a new unit in ‘Open Access’ mode In ‘Open access’ mode, adding a unit requires simply to switch the unit on. It will then automatically connect to the WCAP in operation. 13.2.6. Adding a new unit in ‘Controlled Access’ mode In a ‘Controlled Access’ set-up, adding a unit requires the following steps: 14. Switch on the wireless unit to add and wait a few seconds until the unit has discovered the WCAP (see chapter xxx) 15. Open the existing initialization by selecting the “Start Init”, , button. 16. After you started the new initialization, the LED’s on the wireless unit(s) will start to blink. The LED’s on the units that are already known in the init list will automatically go out. 17. Add the new wireless unit(s) by pressing the microphone button on the unit(s). 18. Stop and save the initialization by pressing the “Save and Stop Init” button, . Note: When multiple WCAPs with ‘Open Access’ are in operation in the same area, there is no control over which WCAP the new unit will connect to.
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 52 13.2.7. Reviewing Init information At any time it is possible to see how many units are known by the system, “Units in Init List”, and to see which units are actually connected with the WCAP, “Units Initialized”. This information is visible in the “Unit Monitoring” and “Init Units” sub tabs in the “Conference Management” menu (see Figure 13.2) Figure 13.5 shows the information on the screen when 1 unit is listed in the Init List but not connected with the WCAP: Figure 13.5: Init example 1 Figure 13.6 shows the information on the screen when 1 unit is listed in the Init List and this unit is switched on and connected with the WCAP: Figure 13.6: Init example 2 13.3. Coupled mode If the WCAP is used in combination with a wired central conference unit, e.g. TCS2500 or TCS5500, then the initialization procedure explained for that wired unit has to be followed. Reference: Refer to the manual of the connected central unit for the initialization procedure Note: The Init control like displayed in the web server has no functionality when the WCAP is coupled with another wired conference unit.
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 53 14. Encryption 14.1. Introduction To secure all communication between the WCAOP and the wireless delegate units, all information that is passed over the radio link is encrypted by default, using a default encryption key. This key is identical for all Televic equipment. To this default key, a custom encryption key can be added. This further enhances the confidentiality, but can also be used to control access in an environment where multiple adjacent rooms are using a Confidea conference system. In this way, access can be restricted to a single room or a selection of rooms. The custom key as it were adds a unique relationship between a wireless unit and a given access point. 14.2. Default encryption By default the system uses an encryption mechanism that is known by each unit in the wireless conference configuration. By using this setting it is possible to add new units in the conference configuration or using the delegate units with other WCAP’s at any time (also see Initialization) 14.3. Setting the default encryption The default encryption mechanism can be set by following these steps: 19. Select the “Key assignment” sub tab in the “Encryption” menu from the web server. Figure 14.1: Web server key assignment page selection The following screen will appear: Figure 14.2: Key assignment page 20. Select the “Use default key” option to return to the default encryption mechanism Figure 14.3: Default key selection Note: The advanced encryption mechanism used in the Confidea system makes decryption by third party equipment practically impossible.
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 54 14.4. Custom encryption The Confidea wireless conference system can be personalized by defining and selecting a unique encryption key. By using a customized key, only the units that have this key, i.e. on which the specific key has been uploaded, can connect with the WCAP. All other units will be rejected. It is impossible to receive the transmitted audio signal with a unit that does not have the customized key. Up to 3 (TBD) customized encryption keys can be defined. 14.5. Setting a customized encryption To set up your system with a custom encryption key, carefully follow these steps: Step 1 - Check your configuration Before uploading the custom key check if all units in your system are switched on and connected to the WCAP. Verify if the correct number of units is logged-on by checking the “Units Initialized” number which can be found under the “Unit monitoring” or “Init Units” sub tabs in the “Conference management” menu. Please refer to the initialization chapter (ref.) for more information. Step 2 – Go to the Key assignment web page Select the “Key assignment” sub tab in the “Encryption” menu from the web server (refer to Figure 14.1.) The key assignment page will appear (refer to Figure 14.2) Step 3 – Enter a new encryption key In this example we will modify custom key 1. To manually enter a new custom key, choose a 32-character long encryption key and manually enter it in the text box next to the “custom key 1” mark (refer to Figure 14.4). Note: If delegate units have received custom keys in the past, it may be necessary to select the default encryption mechanism first, (refer to chapter 14.3 Setting the default encryption) to allow each unit in the system to access the WCAP. Note: Once uploaded to the delegate units, custom keys cannot be retrieved from the system. Note: The basis of the encryption mechanism cannot be altered, so adding a custom key does not affect the encryption strength. Default- and custom encryption yield an encryption strength that is equally high.
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 55 Alternatively, the system can generate a random 128-bit (32 hex characters) encryption key for you. To do this, click the “Calculate 128-bit full key” button (refer to Figure 14.4). Figure 14.4: Custom key entry field Step 4 – Upload a new encryption key After a key has been generated it must be uploaded into the system. Not only the WCAP, but also all wireless delegate units that need to connect with the WCAP must know the same key. Upload the key by clicking the “Upload key” (refer to Figure 14.4) Step 5 – Activating the new encryption key The WCAP will start encrypting the transmitted data and audio after a custom key has been selected. Figure 14.5: Custom key selection If the WCAP needs to use the selected key next time it powers up, push the button. Caution: Wireless units not containing the same encryption key as selected, because they were not connected with the WCAP at the time of upload, can no longer connect with the same WCAP. The units will be ignored by the system! Caution: Only the units that are connected with the WCAP can receive the newly generated encryption key. Other units will be ignored! Note: During the upload, the microphone LEDs will flash. Once the upload is successful, the LEDs go out. Caution: Only use hexadecimal characters i.e. choose 32 characters from the following list: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f. If a key shorter than 32 characters has been entered, then the remaining positions will be filled with zeros. If a key longer than 32 characters has been entered, then the key will be truncated after the first 32 characters.

Basic discussion In a basic setup where only discussion is applicable, the Wireless Conference Access Point WCAP (see link to chapter WCAP) acts as a central control unit. This means the system can operate without the need of an extra central control unit (CE2500 or CPU5500). Units applicable to this setup are listed below: Confidea DD Confidea CD In a standalone configuration power needs to be supplied to the WCAP separately. (see chapter WCAP power supply) Configuration and monitoring of the system can be done via the build-in web server, which is accessible via a standard web browser. (See chapter system configuration) Figure 15.1: Stand alone set up for basic discussion Note: In this case the chairman needs to guide the meeting by using his prior and next-inline button. Microphone activation by an operator is not possible via web server application.
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 60 15.2. Basic voting and opinion polling In a setup where there is only a need for basic voting or opinion check, the Wireless Conference Access Point WCAP (see link to chapter WCAP) acts as a central control unit. This means the system can operate without the need of an extra central control unit (CE2500 or CPU5500). Units applicable to this setup are listed below: Confidea DV (Figure 6.1 and Figure 6.4) Confidea CV In a standalone configuration power needs to be supplied to the WCAP separately. (see chapter WCAP power supply) Configuration and monitoring of the system can be done via the build-in web server, which is accessible via a standard web browser.

Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 61 Chairman has control over the voting session. With the voting session control buttons (see Confidea Wireless units - Controls and indicators) he can start, pause or stop a voting session. Figure 15.3: Voting control buttons After pressing the stop button, the voting session is terminated and the results are distributed to the information display of all registered Confidea units. Figure 15.4: Voting information display Pressing the stop button a second time clears the voting results. Note: The voting results are not stored in a file in this setup. In case there is a need see use case CE2500 or CPU5500
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 62 16. Connected to CE2500 or CPU5500 As the Confidea system is an addition to the Televic product family it is also possible to combine the Confidea system with the existing TCS2500 and TCS5500 system (refer to Figure 16.1: Televic Family concept) This family approach makes it possible to create a conference system fitting every customer needs. In situations where every now and then an extension of the fixed conference system is required, adding some wireless units can reduces the setup costs drastically. Depending on the demands of a project the central control equipment of the TCS2500 or TCS5500 does the job. The Confidea access point (WCAP) can be directly connected to one of the digital output busses of the TCS2500 central control unit. (CE2500/B) Connecting the Confidea access point to the central control equipment of the TCS5500 requires an additional splitter unit (SPL5525). In the following section three possible applications are described. This will help to define the correct system architecture for a given project. Figure 16.1: Televic Family concept Reference: When using Confidea in conjunction with other Televic conference systems and PC control software, please refer to the User Manual of those systems for more information.
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 63 16.1. Discussion For these applications, delegates of the meeting have a contribution unit with only a microphone to participate in an ongoing discussion. Several criteria can influence the choice of the Televic central control unit to be used. The criteria described below should guide you in designing the best possible system architecture for a given project. Figure 16.2: Central control equipment selection criteria Project size The number of participant units in a meeting will influence the descision on the system to use. The TCS2500 central control unit is limited up to 120 active delegate units. Projects requiring a larger number of participants should use the TCS5500 central control unit with expandable system architecture. Table 16.1 below gives an overview on the system compatibility. Table 16.1: Project size vs. Televic system Number of Participants TS2500 TCS5500 <50 • (CE2500/B) • 50 > 120 • (upgrade full option) • > 120 •
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 64 External Audio Peripherals PA systems: Whereas the Confidea units have a build in loudspeaker, some meeting rooms are equipped with external PA systems with loudspeakers installed on walls or in ceilings. Making use of such a setup, the floor language of the conference system needs to insert into the PA system. This requires an analog output, which is available on the central control equipment of both TCS2500 and TCS5500. Recording: Whenever meetings reports need to be written or audio of meetings is being published on the web, recording needs to take place during the meeting. The recording device (hardware or software solution) needs to have an analog input signal provided by the conference system. Both the Televic TCS2500 and the TCS5500 central control units have 7 analog outputs available. Additional outputs can be provided by adding external TCS5500 output equipment to the TCS5500 system. Audio reproduction: Feeding external audio signals (music before meeting, DVD sound, input external microphone, telephone line, …) into the conference system requires analog inputs on the central control unit. Both the TCS2500 and TCS5500 central control units have two analog inputs. If this is not sufficient the TCS5500 system has the capability to connect additional input equipment. Table 16.2: I/O Equipment vs. Televic system I/O TS2500 TCS5500 Input 2 2 Expandable Output 7 7 Expandable Connectivity Operator Control: Systems requiring a great degree of control can be equipped with the Televic software suite. This application makes it possible, depending on the license, to control the microphones in a meeting, assign delegate names, control speech time, display delegate and speech time information on monitors or projection screens. It offers easy initialization and configuration capabilities supporting an easy set-up and break-down, essential for successive meeting planning with low delays like convention centers. Furthermore it visualizes the battery and RF quality status of all units, giving the operator/technician the ability to assure no interruptions once the meeting started. Camera Control To enable a camera system to visualize the currently active Confidea user, a device bus controller needs to translate the commands received from the Televic system into preset positions of the camera control system. Both the TCS2500 and TCS5500 systems will do the job. The difference between the TCS2500 and the TCS5500 system on connectivity level is the way the communication takes place. The TCS2500 uses a serial communication protocol, whereas the TCS5500 system has additional IP connectivity.

Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 65 16.2. Advanced Voting The stand alone voting setup can be seen as an informal voting session. Making use of a Televic voting software suite enables following features: Voting agenda Voting session configuration options Voting result reporting Voting logging Voting result visualization All of these options are available for as well TCS2500 as TCS5500 systems. Main differences between the two systems are: Voting by authority Customizable voting result visualization Table 16.4: Voting vs. Televic system Voting TS2500 TCS5500 Authority • Result visualization fixed customizable 16.3. Interpretation Systems with simultaneous interpretation as a requirement always require a central control unit in combination with the interpreter desks. Installation Whereas the TCS2500 interpreter desks are of the table-top type, the TCS 5500 interpreter equipment can be semi-flush mounted. Conformity Standard The ID5500 interpreter desk is conform to the XXXXX standard and approved by interpreter organizations as the European Commission (SCIC), United Nation, AIIC. Interpretation capabilities The Confidea wireless system has the capability to send up to 12 languages to the contribution units. Both the TCS2500 and TCS5500 systems are capable of handling that number of languages. External Equipment As already described in External Audio Peripherals the number of analog outputs required for recording or needed to connect to an Infra red distribution system will determine the central equipment to be used. Table 16.5: Interpretation vs. Televic system Interpretation TS2500 TCS5500 Installation Table-top Semi-flush mounted Standard xxxx xxxx # languages Confidea : 12 Confidea : 12 # outputs 9 Expandable Next to these points it is also possible to connect interpreter systems of other vendors. That way it is
Confidea Wireless System Installation and User Manual Televic Conference Systems 2008-09-05 66 possible to use the Confidea system without the need to change all the interpreter desks. The PIO unit of the TCS5500 plays an imported role in such configuration handling the floor and interpretation languages between the two systems.
