Product Presentation

Here is a survey of what you will find in this section:

•Purpose

•How to Cut Telephone Costs

•Other Advantages and Applications

•RF Radiation Safety Precautions

3

1.1.Purpose

•The 2N - VoiceBlue Lite gateways help interconnect SIP based VoIP networks directly with GSM networks. They can also be used for a direct connection with a VoIP telephone set.

•The voice mode, i.e. an outgoing or incoming call, is the basic function of the system. The gateway is equipped with all functions necessary for such use and provides a very high comfort in this mode.

•In addition to voice transmission, the 2N - VoiceBlue Lite gateways enable to send and receive SMS messages.

•No extra equipment (an external GSM telephone, etc.) is needed for normal operation. To set the basic parameters use the configuration software included in the product CD. All programmable parameters are default-preset in such a manner that you can commence your telephone traffic the moment you connect the Ethernet and supply cables, antenna and SIM card and set the GSM and VoIP parameters.

1.2.How to Cut Telephone Costs

•Once you connect the 2N – VoiceBlue Lite gateway to your VoIP PBX, you can make all outgoing calls to a mobile network directly. Thus, you cut your PSTN - mobile network call costs. All mobile telephone calls from your personnel in the field are cheaper too.

•You are advised to use the most advantageous rate of your GSM provider for your GSM gateway because all gateway user call accounts are added up for billing purposes.

•You can bar selected numbers or groups of numbers in your gateway. You shall pay nothing for the calls you have barred.

•2N - VoiceBlue Lite keeps detailed records on all calls. This helps you find out easily why your bill is higher than it should be.

•The Least Cost Router is flexible enough to help you set rules for GSM calling at the lowest possible operation costs.

2N - VoiceBlue Lite

•The intelligent Callback function enables your personnel to call at the cost of your GSM gateway SIM cards.

1.3.Other Advantages and Applications

•2N - VoiceBlue Lite integrates the best of the GSM and VoIP communication technologies.

•The GSM gateway keeps detailed statistics on incoming and outgoing calls.

•With the Compact Flash memory you get an almost unlimited depository for your call records.

•The Intelligent Routing of Incoming Calls function accelerates the incoming call establishing and provides a higher calling comfort.

•The DISA function with the option to record easily a welcome note is available.

•You can use the conditioned or unconditioned call forwarding function.

•You can disable the CLIP function on your GSM telephone set.

•Unlike mobile telephones, this system does not expose you to the RF electromagnetic field while making calls.

•All functions may be configured through the Ethernet, USB and serial interfaces.

•With the aid of external software, you can implement your VoiceBlue Lite gateway into the Unified Messaging system of your company.

1.4. RF Radiation Safety Precautions

It is prohibited to use any transmitters, including VoiceBlue Lite, in areas where explosives are used, such as quarries.

It is forbidden to use mobile phones and thus VoiceBlue Lite too at refuelling points.

A GSM gateway may affect sensitive life-saving devices in medical centres. So it is prohibited to use mobile phones and thus VoiceBlue Lite here.

In general, any restriction regarding mobile phones based on RF energy radiation applies to GSM gateways.

Where necessary, VoiceBlue Lite may be installed at a safe distance (in the neighbouring building, e.g.) and an Ethernet cable may be carried from the GSM gateway to the original building.

Although GSM gateways are not intended for aircraft or cars, all relevant restrictions and regulations regarding mobile phones apply to them here.

Fig. 2 – Top View

2.2.Brief Installation Guide

•Proper mounting – 2N – VoiceBlue Lite is designed for suspension on a vertical surface. Fit the holder included in the delivery on a wall and hang the gateway on it. For details on the prescribed working position and other recommendations refer to Subs. 2.3.

•Cable connection – connect the gateway using an Ethernet cable to your VoIP PBX (or any other VoIP terminals). For more details on proper wiring refer to Subs. 2.4.

•Antenna connection – connect an external antenna cable into the SMA antenna connector. Place the antenna on a place with a good GSM signal (refer to Subs. 2.5).

•Gateway power supply – the delivery includes a mains adapter. Make sure that an antenna has been attached to the antenna connector before supplying voltage. Plug in the adapter connector into the GSM gateway and the power adapter into a wall socket. The gateway turns on immediately (see Subs. 2.6).

9

•SIM card insertion – SIM cards are inserted in holders on the gateway top. The SIM card holder is of the push/pull type, which means that all you have to do is insert a SIM card and press the holder gently until it snaps into position (see Subs. 2.7). Secure the SIM card with a latch to avoid incidental removal. !CAUTION! If you use PIN-asking SIM cards, first set an identical PIN code for all SIM cards used in the GSM gateway, save it into the GSM gateway configuration and only then insert the SIM cards in the GSM gateway.

•PC connection – the gateway parameters are normally set using the configuration software available on the CD included

in the delivery. To interconnect your PC with 2N - VoiceBlue Lite use the USB cable* or laplink RS 232 cable** included in the delivery.

•Configuration program installations - run the installation file from the installation CD on a PC connected to the gateway and install the VoiceBlue Lite configuration software (refer to Subs. 0).

•Configuration program - run the VoiceBlue Lite program and set the serial port communication for your PC - gateway connection. Establish communication between your PC and the gateway (refer to Subs. ).

•2N - VoiceBlue Lite configuration - now use the configuration software to set all necessary gateway parameters - VoIP parameters basic GSM parameters and tariff metering/pricing parameters, routing, restrictions, system parameters, and input and switch properties. Having set the required parameters, upload the configuration data to the gateway via a serial link. For more details on the configuration software see Section 9.

* Be sure to install the drivers available on the CD included when you use a USB cable. **of the same type as used for direct PC-PC connection.

2N - VoiceBlue Lite

2.3.Proper Mounting

•The 2N - VoiceBlue Lite gateway is designed for mounting on a vertical surface. For this purpose a wallmounting holder is available. Just fit the holder with dowels and screws (Fig. 3) to the wall and hang the gateway as shown in (Fig. 4).

Fig. 3 – Gateway Holder Wall-Mounting

Fig. 4 – Gateway Hanging

•It is possible to operate the VoiceBlue Lite gateway in another working position (e.g. on a desk) for a short time only, for example in servicing centres for quick testing purposes.

11

•Exceeding the recommended operating temperature values may not affect the gateway function immediately but may result in more rapid ageing and lower reliability. The allowed working temperature and relative humidity ranges are included in Section 12.

•The gateway is intended for indoor use. It may not be exposed to rain, flowing water, condensed moisture, fog, or mist.

•The gateway may not be exposed to aggressive gas, acid vapours, solvents, etc. or aggressive liquids, during cover cleaning, for example.

•The VoiceBlue Lite gateway is not designed for high-vibration environments e.g. means of transport, machine rooms, etc.

•Free space has to be left under and over the gateway for cables and agitated air to remove operational heat.

•Install the gateway on a place with a good GSM signal.

•A misplacement of the GSM gateway or its antenna near television, broadcasting or similar RF-sensitive devices may evoke an adverse effect upon their function.

•Being a source of RF energy emission, the VoiceBlue Lite gateway antenna should not be located close to human bodies. The hazard is higher than with mobile telephones because the gateway is usually used by many people and thus employed more often.

2.4.PC or LAN Connection

The 2N - VoiceBlue Lite gateway can be connected to a PC using a USB cable terminated with a USB B connector or a laplink serial cable with RS 232 connectors. A direct connection of 2N - VoiceBlue Lite and a PC is necessary for the initial gateway configuration when the gateway IP address is unknown and the gateway cannot be configured using the LAN.

VoiceBlue Lite supports connection via the Universal Serial Bus (USB) of version 1.1. In this type of connection, however, it is necessary to install VoiceBlue Lite drivers into your operating system (OS). At present, the drivers support the Microsoft

12

2N - VoiceBlue Lite

Windows 98SE/ME/2000/XP OS. While installing the drivers please following the instructions below:

•Insert the included CD into your PC CD-ROM drive.

•Connect the USB cable to the PC and then to VoiceBlue Lite.

•The Windows OS recognises the connected device automatically and asks for suitable drivers.

•Find the VoiceBlue Lite drivers on the CD included in the delivery in the following directory: CDROM:\VoiceBlue\USB drivers.

•The OS recognizes the right drivers automatically and starts installing them.

The OS may also require the USB COM port drivers. They are available in the same CD directory as mentioned above.

The VoiceBlue Lite gateway operates as a modem in the data mode, communicating through a virtual COM port. The gateway USB port default parameters are 921,600 bps, 8 data bits, no parity, 1 stop bit, and no flow control. If you intend to use the USB cable for distances longer than 5 meters, you are recommended to use the USB hubs.

.

Fig. 5 – Direct PC Connection Using USB

The serial port transmission rate is 57,600 bps, the remaining communication parameters are the same. Set the communication parameters on the PC side identically.

14

2N - VoiceBlue Lite

2.5. Antenna Connection

The VoiceBlue Lite gateway has one SMA antenna connector for all GSM modules, see Fig. 9. An external antenna cable is connected to this connector. The external antenna should be installed vertically on a place with a good GSM signal. For the technical parameters of the antenna refer to Section 12.

Fig. 9 – Antenna Connection

Tighten the antenna connector gently with your hand, never use a wrench!

2.6.Gateway Power Supply

•Be sure to use only the mains supply adapter that is included in the gateway delivery.

•Before plugging in the gateway, make sure that the mains voltage value meets the data given on the mains adapter label.

•Make sure that the antenna has been connected. If you connect the gateway to the power supply without an antenna, the GSM module transmitter might get damaged.

•Now plug the supply adapter into a wall socket and after it connect the adapter connector to the gateway, see Fig. 10. The status indicators indicate the proper operation. For their meanings refer to Subs. 2.9.

15

Fig. 10 – Supply Adapter Connection

2.7. SIM Card Installation/Removal

Insert the SIM card into the SIM card slots with your hand as shown in Fig. 11. Please make sure that the slashed SIM card side is on a side opposite to the latch. Having inserted the SIM card, push the card gently until you hear a click signalling that the push/pull holders have snapped the card. Secure the SIM card by shifting the latch to the right in order to avoid incidental removal of the SIM card.

To remove the SIM card take the opposite steps. You can replace a SIM card even with the gateway on.

16

2N - VoiceBlue Lite

Fig. 11 – SIM Card Inserting Procedure

Each SIM card inserted in the gateway has a unique set of parameters. Their values are bound to the card IMSI, remain stored in the gateway even if the SIM card has been removed and thus need not be reset upon SIM card re-insertion.

2.8. PIN Entering Disable (Optional)

2N - VoiceBlue Lite is set at automatic PIN entering by default (1234). To disable the PIN use any mobile telephone in which you insert the given SIM card. By disabling the PIN entering you invalidate any other VoiceBlue Lite parameters or PIN stored in the gateway memory. If you do not disable this function, VoiceBlue Lite will always ask for a PIN by LED signalling, which must be identical for all SIM cards inserted.

2.9. Status Indicators

There is a panel with five LEDs on the gateway upper cover for a quick GSM gateway status detection (see Fig. 12). The Power LED signals that the gateway as a whole is in operation. The GSM 1 to GSM 4 LEDs indicate the status of the respective GSM modules.

17

Fig. 12 – Signalling LEDs

Basic diagnostic tests and gateway initialisation are performed automatically whenever the gateway is connected to supply voltage. Each test step is signalled by a specific colour combination of the LEDs. If a test step fails, the indicator combination related to the failed test remains lighted.

Power Indicator

The Power LED signals whether the VoiceBlue Lite gateway is supplied or not.

Continuous light		The system is working.

Tab. 1 – Survey of Power Indicator Statuses

GSM Indicators

The GSM 1 to GSM 4 LEDs signal statuses of the respective GSM modules. Whenever the 2N - VoiceBlue Lite is started, detection of the GSM modules is carried out. This process is signalled by a green LED. If all GSM modules are present and ok, the LED goes out. After that the firmware and configuration uploading process is initiated, which is signalled by various LED colour combinations. The initialisation process is followed by a check of presence of SIM cards in slots. Quick blinking of the green LED of the respective GSM module indicates this procedure. If a GSM

18

2N - VoiceBlue Lite

module or a SIM card is absent, the red LED remains lighted. If a GSM module is not supplied, the respective GSM LED is blinking red. Upon a correct GSM module initialisation, the SIM card is logged in, which is signalled by a quickly blinking green LED. If the log-in has been successful, the LED goes out. If not, it shines red continuously.

In normal operation, a continuous green LED indicates an incoming or outgoing call within the particular GSM module.

It is unnecessary for the gateway function. Its average service life is approximately 3 years. You are recommended to replace it after three years for preventive purposes or, at least, check the voltage with a voltmeter (the value should not drop below 2.9V). A completely low battery results in the VoiceBlue Lite gateway losing the time and date information and false data appear in the trace and also in the service log buffer listing.

21

To replace the lithium battery, first disconnect your VoiceBlue Lite gateway from the mains and open the cover. Remove the old battery from the holder using a suitable tool and install a new one. We recommend you to have this service done by a 2N servicing centre.

2.11.Fuse Replacement

WARNING! Use only a fuse of the same type.

Disconnect the adapter power while replacing the fuse.

Fuse can be replaced only by service which is personnel qualified to check such parameters as power consumption, DC voltage etc.

If fuse fails again, unit must be returned to manufacturer for repair

To exchange the fuse disconnect power adapter cable first. The location of the fuse on the main board is on the Fig. 13. Open the cover, remove the faulty fuse and check it. Replace the fuse by a fuse of the same type only. Close the cover and reconnect the power adapter cable.

2.12. Antenna Splitter

The antenna splitter is a passive component that enables several GSM channels to share a single antenna. With VoiceBlue Lite it joins four antenna ports into one external antenna. This splitter saves both antenna costs and installation space. It is a passive element – it has a characteristic signal attenuation that the connected antenna must compensate. For technical parameters of the splitter and antennas refer to Section 12.

2N - VoiceBlue Lite Installation

This section shows how to install the VoiceBlue Lite gateway properly to avoid gateway operation troubles.

This section includes:

•Proper Installation Conditions

•VoiceBlue Lite Installation

•Potential GSM Network Problems

24

2N - VoiceBlue Lite

3.1. Proper Installation Conditions

The following installation conditions must be met for a proper function of VoiceBlue Lite:

•Sufficient space for VoiceBlue Lite installation.

•Sufficiently strong signal from the GSM network with which VoiceBlue Lite shall work with (the minimum signal intensity value is –80dBm). To measure the signal intensity before VoiceBlue Lite installation you can use a mobile telephone with the Net monitor function enabled (e.g. SIEMENS, NOKIA).

•A corresponding capacity of the GSM network (no GSM cell overloading). Remember that the use of multiple GSM gateways in one location may overload your current GSM cell base. This might lead to a permanent or occasional rejection of calls to GSM networks!

•No strong electromagnetic radiation on the installation site.

•No strong reflections on VoiceBlue Lite antenna sites.

•A correct VoIP connection configuration according to SIP and other VoIP recommendations.

3.2.VoiceBlue Lite Installation

•Place the VoiceBlue Lite GSM gateway to an environment that meets the gateway working conditions.

•It is recommended to connect the supply adapter with a battery backup (UPS) and appropriate surge protection.

•Configure the GSM gateway using the VoiceBlue Lite software available on the product CD enclosed.

•You may use remote GSM gateway administration through the Ethernet for a comfortable GSM gateway management.

25

3.3. Potential GSM Network Problems

The VoiceBlue Lite GSM gateway is designed for a continuous 100% load. The GSM network may cause the following problems:

•The GSM module(s) cannot log in, log in slowly or log out occasionally. This might be caused by any of the events below:

•The signal intensity received from the GSM network is too weak – the recommended minimum value is -80dBm. If the signal is lower, change the antenna position or type.

•The GSM cell to which the GSM modules log in is overloaded. Change the antenna position, or reduce the number of GSM channels connected to the troubled GSM network.

•One of the GSM modules keeps logged out or is unable to process an outgoing call – this indicates a potential GSM network overload on the installation site. To solve this problem, set the parameter “Relax delay” = 2. If a GSM module fails to log in or refuses to process a GSM call even after the gateway restart, check your GSM network provider for potential SIM card or GSM module blocking.

VoiceBlue Lite Connection to VoIP

This section discusses VoIP connection possibilities of the 2N - VoiceBlue Lite gateway. Since 2N - VoiceBlue Lite communicates using the SIP only, the interconnection of SIP and H.323 networks is mentioned here too. 2N - VoiceBlue Lite may be operated in the Point-to-Point or Point-to-Multipoint mode with a SIP Proxy server.

This section includes:

•SIP and H.323 Network Interconnection

•Point-to-Point Configuration

•Point-to-Multipoint Configuration

28

2N - VoiceBlue Lite

4.1. SIP and H.323 Network Interconnection

SIP-based devices cannot communicate with H.323-based ones directly but through a SIP/H.323 gateway. This gateway transfers signalling reports of both the protocols. Using the RTP (Real Time Protocol) for multimedia data transmission, both SIP and H.323 devices can communicate directly with each other after getting interconnected by a SIP/H.323 gateway. Therefore, 2N - VoiceBlue Lite may be implemented into the existing H.323 environment using a SIP/H.323 gateway.

4.2. Point-to-Point Configuration

In the Point-to-Point mode, VoiceBlue Lite can only communicate with one SIP VoIP telephone or another SIP VoIP terminal, e.g. a VoIP gateway. The IP address of the opposite side is always set as the Proxy server IP address in the VoiceBlue Lite P-T-P mode.

29

The VoiceBlue Lite configuration with one SIP VoIP telephone is often used for testing purposes before implementation to the VoIP network. For this connection see Fig. 15.

Fig. 15 – Point-to-Point Configuration with SIP VoIP Telephone

In the Point-to-Point mode using a VoIP gateway, all calls assigned to GSM are routed to VoiceBlue Lite by the VoIP gateway. You can either set the IP address of the opposite side as the Proxy server IP address for the two terminals, or, with an intelligent VoIP gateway, resend certain calls to the VoiceBlue Lite IP address directly.

4.3. Point-to-Multipoint Configuration

The Point-to-Multipoint arrangement means a classical structure of a distributed VoIP network with one or more SIP Proxy servers (VoIP gateways). The SIP Proxy is a software PBX version (or a standard PBX enhanced with VoIP services), which manages all signalling in the VoIP network. In this mode you can use multiple source terminals (e.g. VoIP telephones) and multiple destination terminals (e.g. VoiceBlue Lite). An internal routing algorithm (LCR) of your SIP Proxy is used for routing calls to GSM and other networks. GSM calls may be routed through the VoiceBlue Lite gateway. All signalling (SIP) is managed by the SIP Proxy and the subsequent voice stream is transmitted by the RTP in the Point-to-Point mode.
