1.1 Product Description

The GSM gateway provides direct interconnection of the2N Enterprise / BRI Lite

ISDN with GSM networks. It can also be used for direct interconnection of an ISDN PBX with a GSM network, ISDN telephone set and, via a terminal adapter, with an analogue apparatus or coin machine. The voice mode, i.e. outgoing and incoming calls, is the basic function of the gateway. Moreover, the BRI gateway provides connection to the VoIP–SIP networks. The gateway is equipped with all functions necessary for this mode

and is very user–friendly. In addition, allows you to 2N BRI Enterprise / BRI Lite

send and receive SMS messages. No additional devices (an external telephone, e.g.) are required for normal operation. All gateway parameters can be set using a configuration program (on an enclosed CD), or using the AT commands. Programmable parameters are pre–set to make it possible to make calls as soon as the supply cable, antenna a SIM cards are connected.

2N® BRI Enterprise / 2N® BRI Lite Differences

The and gateways are based on one and the2N® BRI Enterprise 2N® BRI Lite same type of hardware and apply identical firmware and control (configuration) software. The only difference lies in the count of BRI ISDN interfaces:

*The VoIP–SIP support depends on Part No. (subject to licence).

Telephone Cost Cuts

Having connected to your ISDN PBX, you can2N® BRI Enterprise / BRI Lite make calls to the mobile network directly. This saves your PSTN – GSM

.connection costs You do not pay for barred calls. You can set groups of barred numbers in the gateway. A flexible setting of the Least Cost Router helps you call GSM numbers at

.minimum operational costs You can route calls to alternative providers' networks via the VoIP/SIP interface. As all gateway user calls are added up for billing purposes, you are advised to use the most advantageous tariff offered by your provider.

functionality. DialThru enables the gateway to be connected between the PBX and the voice service provider line, i.e. PSTN. The GSM gateway in the DialThru mode routes, based on the LCR, calls into the PSTN or GSM/UMTS networks.

Refer to the figure below for a schematic diagram of the connecti2N BRI Enterprise

on.

72N TELEKOMUNIKACE a.s., www.2n.cz

The gateway works as a dial–through router (using both the TE and NT ports in the DialThru mode) for calls to a mobile network, and a monitoring system, which, with the appropriate licence, sends SMS to the provider (in the case of line unavailability, e.g.).

The GSM gateway contains just one ISDN BRI port and thus cannot2N BRI Lite

work in the DialThru mode. It can be connected to a PBX on a trunk line or extension and route calls to the GSM/UMTS networks only – see the figure below.

82N TELEKOMUNIKACE a.s., www.2n.cz

1.2 Safety Precautions

It is prohibited to use any transmitters, including the GSM/UMTS gateways, in areas where explosives are used, such as quarries.

It is prohibited to use the GSM gateways at petrol2N BRI Enterprise / BRI Lite

stations where mobile telephones are also prohibited. GSM phones may affect sensitive life–saving devices in medical centres. Therefore, it is forbidden to use GSM/UMTS devices, including the GSM gateways, in such facilities. In general, any prohibition regarding mobile phones based on RF energy radiation applies to GSM/UMTS devices too. If necessary, the GSM gateways may be installed at a safe distance from the prohibited area and connected with the original place through an Ethernet cable. Although GSM gateways are not intended for cars or aeroplanes, all relevant prohibitions and regulations regarding mobile phones apply to them too.

Potential GSM/UMTS Troubles

All gateways work reliably under a long–time full load. The following2N GSM

problems may be caused by GSM/UMTS networks:

The GSM/UMTS module(s) cannot log in, log in slowly, or log out occasionally. This problem may be caused by any of the following situations:

The GSM/UMTS signal is low. The minimum signal level should be approximately . If lower, change the antenna position or type!–80dBm The GSM/UMTS cell (BTS) to which the GSM/UMTS modules are trying to log in is overloaded. Change the antenna position or reduce the count of

the logged–in GSM/UMTS modules. One of the GSM/UMTS modules is permanently logged–out or fails to make outgoing calls:

The problem indicates a GSM/UMTS network overload on the installation

site. To eliminate the problem, set the parameter to Relax delay 2

2.4 IP Voice Transmission

Speech Encoding Methods

Voice transmission is strictly separated from signalling in VoIP networks. Modern VoIP networks mostly use the RTP (Realtime Transport Protocol) for voice transmission. The purpose of the RTP is only to transmit data (voice) from a source to a destination at real time. Codecs are used to save the channel data capacity. Codecs process the voice signal using variable algorithms to minimise the volume of user data. The degree of compression used by the codec affects the quality of voice transmission. Thus, the better voice transmission is required, the wider data range (the higher transmission rate) is needed. The MOS (Mean Opinion Score) scale is used for rating voice transmission quality, where 1 means the worst and 5 the best quality. For a survey of

the codecs supported by gateway refer to the table below.2N BRI

Codecs supported

G.711u PCM 64 4.1

G.729 G.729 is an optional part of the system.

CS–ACELP 8 3.92

For gateway, quadruple the above mentioned rates (two fully duplex calls) 2N BRI

and add the TCP and IP header transmission rate to the result to get the resultant transmission rate. It is important to keep both a stable appropriate transmission rate during connection and a small and identical transmission time per data packet in order to maintain a high–quality voice transmission.

G.711 – this codec is used in digital telephone networks. The PCM (Pulse Code Modulation) is used for voice signal encoding. The sampled signal is encoded in 12 bits and then compressed using a non–linear scheme into the resultant 8 bits. Europe uses the A–law compression system while North America and Japan obey the µ–law. The resultant data flow is 64 kbps. G.729 – this codec uses the CS–ACELP (Conjugate–Structure Algebraic–Code–Excited Linear–Prediction) algorithm with the resultant transmission rate of 8 kbps. The speech signal is split into blocks of 10 ms each. The parameters of these blocks are then inserted in frames of the size of 10 bytes. 2–byte frames are generated for noise transmission.

During call set–up, a codec is selected automatically for voice transmission. g2N BRI

ateway supports the codecs included in the table above. The type of codec to be used depends on your VoIP network (individual devices) and your gateway2N BRI

Initiation Protocol) signalling.

Tip

In the case of separated direct connection of your SIP Proxy and 2N

, use the G.711 codec to achieve a high voice VoiceBlue Next

quality.

SIP Components

The following components are involved in the SIP message exchange:

UAC (User Agent Client) – the terminal device client, which initiates SIP signalling. UAS (User Agent Server) – the terminal device server, which responds to SIP signalling from the UAC. UA (User Agent) – a SIP network terminal (SIP phones, gateways to other networks, etc.), which contains the UAC and UAS. Proxy server – receives connection requests from the UA and transfers them to the next Proxy server if the given station is not under it administration. Redirect server – receives connection requests, but, instead of sending them to the called line, sends them back to the requesting device asking for where to route the request. Location server – receives registration requests from the UA and updates the terminal database accordingly.

All the server components (Proxy, Redirect, Location) are mostly on one physical device called Proxy server, which is responsible for keeping a client database and connection establishing, maintaining and terminating, as well as call routing.

The gateway VoIP–GSM gateway acts as a UA in any case (has the same2N BRI

functions as a VoIP phone), i.e. receives call set–up requirements and, on the basis of its inner LCR table, routes calls to GSM networks.

None of the SIP–defined server components are integrated in the gateway2N BRI

gateway.

SIP Signalling Messages

Below is a list of messages sent via the SIP:

INVITE – connection set–up request; ACK – INVITE confirmation by the final message addressee; BYE – connection termination; CANCEL – failed connection cancellation; REGISTER – UA registration with the SIP Proxy; OPTIONS – server capability query.

282N TELEKOMUNIKACE a.s., www.2n.cz

The answers to the SIP messages are numerically coded as the case is with the http protocol. Below are the most important ones:

1XX – information messages (100 – trying, 180 – ringing, 183 – progress); 2XX – successful request completion (200 – OK); 3XX – request forwarding needed (302 – temporarily moved, 305 – use Proxy); 4XX – error (403 – forbidden, 486 – busy here); 5XX – server error (500 – Server Internal Error, 501 – not implemented); 6XX – global failure (606 – not acceptable).

2.5 Types of 2N® BRI Enterprise Connection

This subsection deals with the types of connection of the gatewa2N BRI Enterprise

y to the main ISDN BRI extension.

ISDN TE – 2N BRI Enterprise Connection

The connection type shown in the figure below provides communication via a GSM/UMTS gateway without PSTN connection. The ISDN telephone sets are connected to the NT port of the GSM gateway, while a mains adapter simulating power supply from the PSTN is connected to the TE port. The adapter is available under Part No.

5020002.

2N BRI Enterprise Point–to–Point Connection

This type of connection is especially suitable for direct calls from an ISDN branch network to a GSM/UMTS network.

Another possible connection type is NT, where gateway synchronisation is derived from

302N TELEKOMUNIKACE a.s., www.2n.cz

the PSTN BRI extension.

With multiple GSM gateways, the connection lay–out is as follows:

2N BRI Enterprise Connection as DialThru Router

This type of connection saves one BRI port to the PBX. Incoming PSTN calls are treated by the GSM/UMTS gateway in the DialThru mode while outgoing calls are routed according to the LCR table. The figure below shows the gateway as a DialThru router for the Point–to–Multipoint extension. Calls are routed automatically into GSM, UMTS or ISDN based on the internal LCR rules.

3.2 Call Routing Principles

2N BRI Lite

The gateway is equipped with one BRI ISDN and one VoIP–SIP ports. You can select one of the following incoming call processing modes for each of the ports via the web interface:

Use LCR table – in this case, calls with be routed as set in the LCR table; Reject calls – all incoming calls will be rejected; Route to port – all calls will be routed to the selected port without change.

If your BRI gateway is connected to a PBX subscriber line, you can activate DTMF. If you do so, the GSM gateway automatically answers any incoming call from BRI ISDN and offers the caller dialtone for another DTMF dialling. The call will then be routed to the GSM/UMTS modules. Incoming GSM/UMTS calls can be either DTMF–processed or automatically routed to the ISDN BRI / VoIP–SIP interface according to the active intelligent GSM gateway rules functions (Auto CLIP, CLIP routing). They are routed to the ISDN NT or ISDN TE interface depending on the GSM gateway configuration. Incoming GSM/UMTS calls can also be rejected and, with the aid of CLIP, used for CallBack. The LCR algorithm routes outgoing calls on the basis of the call type, current time tariff, day in a week and, if available, free minutes of GSM providers.

2N BRI Enterprise

The gateway is equipped with two BRI ISDN and one VoIP–SIP ports. You can select one of the following incoming call processing modes for each of the ISDN ports via the web interface

If your BRI gateway is connected to a PBX subscriber line, you can activate DTMF. If you do so, the GSM gateway automatically answers any incoming call from BRI ISDN and offers the caller dialtone for another DTMF dialling. The call will then be routed to the GSM/UMTS modules. Incoming GSM/UMTS calls can be either DTMF–processed or automatically routed to the ISDN BRI interface according to the active intelligent GSM gateway rules functions (Auto CLIP, CLIP routing). They are routed to the ISDN NT, or ISDN TE interface depending on the GSM gateway configuration. Incoming GSM/UMTS calls can also be rejected and, with the aid of CLIP, used for CallBack. The LCR algorithm routes outgoing calls on the basis of the call type, current time tariff, day in a week and, if necessary, free minutes of GSM providers.

352N TELEKOMUNIKACE a.s., www.2n.cz

Tip

2N BRI Enterprise / BRI Lite® can also route outgoing calls into

the GSM/UMTS networks according to the B–channel used. In that case, the GSM/UMTS module is paired with a specific B–channel of the ISDN BRI line.

LCR Table

The LCR (Least Cost Routing) table is the key telephone cost cutting factor. It helps you set call routing rules according to the CLIP, daytime and day in a week. By entering state (bank) holidays into the LCR table you achieve even more remarkable cuts. To make the prefix–based call routing to external ports and the LCR table work properly, select the module for the call in the parameter whileOutgoing destination creating the LCR record. The gateway also allows you to route outgoing GSM calls on the basis of the SIM card position. Such outgoing calls are not routed according to the GSM provider's number but through the defined GSM module. In addition, the ISDN ports can work in the DialThru mode. This means that all calls are routed to the respective port without any check. Namely, from TE to NT and vice versa.

Outgoing GSM Call Routing from Internal ISDN

If the GSM/UMTS gateway is connected to a subscriber line of your PBX, you are advised to enable the DISA function to GSM to make your GSM gateway answer every call routed to it by the PBX and wait for further dialling to GSM networks. The GSM/UMTS gateway routes outgoing calls to GSM as follows:

The calling subscriber dials a user number. If the user dialling is evaluated as , the gateway barredAccess to GSM gateway number table is searched through and, if a match is found, the call setup request is rejected. With an outgoing call, the gateway waits for further digits to be dialled. This timeout results in a certain delay between the subscriber's dialling and the subsequent dialling by the GSM gateway. Therefore, select the Count of dialled

for the called destinations while configuring your gateway. Then, thedigits gateway initiates the outgoing call processing algorithm on receiving the last digit The dialling prefix is first checked against the prefixes included in the first row of the LCR table. If no match is found, the following row is used for check and so on. In case the prefix and call time comply with the routing rules, the call is routed according to the first LCR rule to the module corresponding to the particular

included in the list.Outgoing GSM group Outgoing destinations If the selected GSM module is busy or has a low credit, the preceding step is repeated and the next LCR row is checked. In case the selected GSM module is free and has a sufficiently high credit, the GSM gateway starts dialling the GSM number. If the calling subscriber number has an unknown prefix or all routes are busy, the

362N TELEKOMUNIKACE a.s., www.2n.cz

GSM gateway rejects the call setup request. An outgoing call is not billed until the called party answers the call. The GSM network signals the off–hook and the GSM gateway transfers this information to the PBX. The gateway is able to generate the AoC tariff pulses during an outgoing call, which, if the GSM gateway is connected to the PBX, allows for call cost logging per user.

Incoming GSM Call Routing

Incoming GSM calls are routed by the algorithm described in the following steps and shown in the figure below: Incoming calls are processed according to the parameter in the Mode Incoming GSM

table. The following options are available:calls

Reject/Ignore incoming calls – incoming calls are not routed to extensions. The call setup request can either be rejected or ignored on the GSM side (the calling party hears the check ringing tone). Report to PC – information on an incoming call is sent to a PC equipped with the management software. The calling subscriber gets a voice message or the check ringing tone. The management software then completes the call routing procedure. CallBack – this function helps establish connection on the account of the SIM card inserted in the gateway. The incoming call is either ignored or rejected. After the calling subscriber hangs up, the GSM gateway sets up connection to the defined extension. When the extension answers, the GSM gateway replays the CallBack message to the extension while establishing connection to the previously calling GSM/UMTS subscriber. After the CallBack message, the GSM gateway interconnects the call. If CallBack with incoming call ignoring is enabled and the calling party fails to hang up within a defined timeout (default=10s), the CallBack function is disabled for this call and the subscriber can go on dialling the extension number. Set the CallBack function in the CLIP routing table. If none of the above mentioned options is selected, the AutoCLIP routing table is checked. If the calling number is found, the call is routed to the extension whose number is assigned to the calling number in the table. In case the calling number is not included in the AutoCLIP routing table, or the AutoCLIP routing function is disabled, the gateway receives the incoming call and either replays a voice message or transmits the dialtone to the calling subscriber. Then the gateway awaits the count of digits necessary for call setup. Define the minimum and maximum counts of DTMF digits in the Incoming GSM calls menu. If the gateway does not receive the minimum count of digits and no other digit comes from the GSM network within the timeout defined in the DTMF dialling

, the call is rerouted to the extension included in the .delay List of extensions

If call forwarding to extension is inactive, the incoming call is rejected.

372N TELEKOMUNIKACE a.s., www.2n.cz

DISA Message

With DISA activated and DISA welcome note recorded, the message is played to every incoming call whose CLIP is not included in the AutoCLIP table. After playing, the gateway waits for the first DTMF digit for the time period defined in the Incoming GSM

table. Having received the count of digits defined in the calls – DTMF dial timeout Inco

parameter, the gateway activates connection toming GSM calls – Minimum DTMF digits the SIP proxy or telephone via the port included in the table with theISDN parameters DTMF–received number. You can upload the DISA message using the GSM gateway web interface. Or, you can record the message using your PC as and load it into the gatewaydisa.wav using the configuration program via the web interface.

DISA Recording via PC and Web Interface

The DISA voice message parameters for PC recording are as listed below: maximum duration of 65s, compression according to ISDN A–law, mono, sampling frequency of 8kHz. Name the file Disa.wav and load it via the weGateway control – Voice messages b interface into the gateway.
