PABX and PC

You do not require an additional ISDN card in your PC. The PABX is equipped with an integrated USB port for con

nection to the PC. You can then set up an Internet connection via the PABX system from your PC (details given on Page 3).

An IPaddress range is required for proper operation of your PABX system (see Page 7). Thiscould resultin conflicts when operating thePABX in parallelwith an additionalIP network (forexample,with DSLrouters).You mustthere

fore ensure that the IP address ranges do not overlap, as this would impair proper functioning within the network and of the PABX system. Makeany necessary changesto PABX system IP addresses, or to the existing network. For example, change the default IP address for the PABX system from 192.168.1.250 to 192.168.2.250.

Note If there isadedicated firewall installedin your PC,theInternet access for thePABX system IP addressmustbe enab

led in the firewall configuration ( see Page 7).

After you installthe programsand drives containedon the CDsupplied withthe system, variousfunctions areprovi

ded by the PC and the PABX via the USB port. You can then:

configure yourPABX via the USB port

searching for and configure your system telephones

edit thephone directory.

Control_Center

The Control Center monitors allISDN router activites while Internetconnections are establishedor terminated.The program is launchedautomaticallyafter beinginstalledevery time thesystem is started.Itindicates forinstance:The provider, the duration of the existing connection, the port (ISDN or DSL), the external IP address assigned by the provider (if applicable),andthe volume ofthetransferred data foruploadand download. AnInternetconnection can also be established or severed via the Control Center. You have the option of selecting to establish Internet access manually or automatically.

If the connectionis established automatically (»Activate automatic connection establishmentwith Internet Service Provider« is active), opening the Internet browser automatically establishes an Internet connection via the ISDN router (factory setting )

Note Additional costs may be incurred if the Internet connection is established unintentionally or not disconnected when desired.We recommend that you do not activatethe item»ActivateAutomatic Connectionto Internet Servi

ce Provider« in your PABX system.

If theconnection is established manually (»Activate automatic connection establishment withInternet ServicePro

vider« is active), a connection to the Internet is only established with the »connect« button in the Control Center«. The connection is severed with the »disconnect« button.

If Internet accessfor the routeris blocked bythe Control Centerbutton »inhibit«, itcan be re-activatedusing the but

ton »enable«. The functions are then restored as configured.

Note If access to the Internet has been blocked through the Control Center, this inhibit is canceled automatically by a PABX system reset, for example interruption of power supply.

Under »Select access method«, specify access viathe router.

Under »LAN selection«, mark »HomeLAN«.

After yourPC has been restarted you will seethe ControlCenter iconin theWindows »Toolbar«.

You can now initiate Internet access via the Control Center, or using the T-Online icon on your desktop.

3. Configuring the PABX system with current Internet access via ISDN (e.g. ISDN card)

Connect thePABX system to the 230 V powersupply systemthrough theplug-in powersupply unit. Do notconnect the PABX system tothe PCthrough theUSB port.

Place theCD suppliedwith the system containing WIN-Tools in thedrive ofyour PCand startthe program »ProfessionalConfigurator«.

Install WIN-Tools on your PC so thatyou canconfigure thePABX system.

Remove the CD containing WIN-Tools and restartyour PC.

Connect theISDN card to the internal S0 busof thePABX system.

Open thePABX Configurator and under »Data exchange« setthe portto »ISDN,internal«.

Program theISDN card as an »InternalS0« subscriber.

Note You mustenter the dial-up number for your Internetservice provider (for example, T-Online 0191011) under »Di

aler protection«.

You can then continue to use the Internet as you normally do.

Description of the ISDN router functions

The PABX system provides allfunctions required forhigh-performance Internet accessfor a PC, via ISDN. Security is provided by a firewall integrated into the PABX system, along with NAT (network address translation).

Internet access for all of the PCs connected to the PABX system is provided via one single connection (SUA - single user account); only one set of access data is required from your Internet service providers (ISP). You can configure more than one ISP.

Description of the ISDN router functions Setting up the ISDN router and WIN-Tools

Page 9

The default holding period for an Internet connection is set to 180 seconds in your PABX system for each provider. That meansthat thePABX system terminates the Internet connection automatically after thisconfigurable timepe

riod when there is no exchange of data from/to the Internet. This can result in increased connection costs with fre

quent, short excursionsinto theInternet, for example for pickingup e-mails,as the connection is alwaysmaintained for the duration of the set holding time. Youcan change this time setting inPC configuration tomeet your personal needs. In theSection»Internet«, »Internet access»selectone of theISPs from thelist and thenclickthe button »Edit«. On the tab »Properties for new Internet provider« under »Dial-up parameters« in the field »Disconnect if inactive for« you can activate/de-activate this performance feature, or can change the setting.

Initial Commissioning and Minimum Configuration

Connection of a PC through USB installation

At present, only Microsoft Windows operating systemsare supportedfor connectionof a PC to the PABX systemvia the USB port. The PABXsystem USBport also functionsas aUSB network card. This meansthat PC configuration of the ISDN router is performed in the same manner as that for an Ethernet installation.

Note If you are connecting your PABX system to an existing network follow the instructions given on Page 1.

Place the CD containing WIN-Tools supplied with the system in the disk drive.

Connect your PCtothe PABX systemusingthe USB cablesuppliedwith the PABXsystem.When both devices(PABX and PC) are switched on, the PC will recognize the linked PABX system and installation of a device driver is then started. Then, just follow the instructions shown on the screen.

When you have successfully completed the connection and configuration the LED marked »USB«on the PABX sys

tem lightsup; when data is being exchanged viathe USBEthernet port this LED will flicker inthe rhythm of data ex

change.

Configuration of the Internet Service providers (ISP)

An InternetService Provider (ISP) provides you withan »entranceportal« to the Internet. A distinction is made bet

ween ISPs with whom you have a contract (for example T-Online) and Internet-by-call providers that bill you through your phone bill (for example Freenet).

The access method does not depend on how rates arecharged; this can be done based ontime or on volume, for ex

ample.

You can use your PABX system to set up an Internet connection via ISDN dial-up connections (using PPP protocol, with one or two ISDN B channels, i.e. at 64 or 128 kBit/s). To set up these typesof connections you need the following access data: the number to be dialed, the user name, the password and, where required, other information, such as IP address for the name server.

Configuring the PCs

IP addresses

The PABX system is configured with a default IP address of 192.168.1.250 and the DCHP server integrated into the PABX is activated, meaning thatany PCs connected to thesystem must be set sothat they automatically receive their IP address from the PABXsystem. Thismode isrecommended to dispense with thecomplicated, manualconfigura

tion of the IP addresses for the PC that would otherwise be required. The following IP-addresses are available:

IPaddress for thePABX 192.168.1.250

IPaddress for thePCconnectedto the USB-port 192.168.1.50

IP-addressesfor RAS-access 1 92.168.1.72-192.168.1.73

IP address allocation

Internet-by-Call

You can usethe Internet-by-Callservice if youdo notwish toconclude a fixedcontract witha provider (ISP)for your Internet connection. Any charges for this will then be listed on your telephone bill. You can also configure Internet-by-Call in addition to an existing contract you may have with a provider (for example, T-Online).

You can easilychange the orderof theISPs with whichthe Internetconnection is tobe set up(»Fallback order« down / up). You can also set the number of and intervals between these attempts at setting up an Internet connection for each ISP that has been configured. When the waiting period between the attempts expires and when the configured number of actual attempts is reached and no connection has been established, the next ISP in the list is selected.

Connection to the Internet is always set up automatically by the PABX system when adata packet is to besent to the Internet. This occurs automatically when you enter http: //www. Funkwerk-ec.com in your browser for example.

Note Automaticconnection to theInternetcan also bede-activatedinthe PABXconfiguration.In this caseyoumustthen initiate setup of every Internet connection via the Control Center (Page 2).

Billing of the costs is made through the telephone bill from your network provider.

Discontinuing an Internet connection

Click the»Control Center«symbol located in the taskbarand thenselect »Disconnect«.

After aset time (which can be defined), duringwhich thereis nodata trafficto theInternet, the connection is terminated automatically.

Description of the ISDN router functions Configuration of the Internet Service providers (ISP)

Page 11

Note If you set the parameter »Terminate on inactivity« too high, this may result in considerable costs for time-based charges.

Note If you have a flat rate charge with your ISP you can deactivate the parameter »Terminate . on inactivity«. In this case the PABX system will not automatically terminate the Internet connection, but will re-establish theconnection ifrequired (for example B: after being disconnectedby theISP). If you have configured several ISPs, make sure that you make this setting for the correct ISP entry in the ISP list.

Terminating the connection to the internet

If the ISDN router of the PABX systemdetermines that there is incomingdata from theInternet the connection will not be terminated automatically when the set inactivity time expires. This can result in considerable costs, even though youare not actually using the Internet connection. Thiscan occur, for example, when a portscan isconduc

ted toward theISDN routerof the PABX(frequently the advancestage of ahacker attack). Afurther possibilityis that peer-to-peer file sharingsoftware has beenrunusing theIPaddress that wasassigned automatically totheISDN rou

ter of the PABX by the ISP. In this case, queries for downloading files from the Internet to the IP address currently being usedfor your Internet connection cancontinue toarrive overan extended period of time. Although these que

ries can not be responded to they can not be technically prevented either.

Note To ensure thatno costs arecharged to youalso use theControl Centerto terminate theInternet connection, orinhibit theISDN router against automatic connection to theInternet (seeControl Center, Page 2). Also checkafter you have switched off your PC to ensure that the ISDN LED indicates that the connection has been terminated.

Note When you use the manualdisconnection methodvia theControl Center,the Internetconnection isterminated im

mediately when you click the button »Disconnect«.

Using a fallback

Let’s assume you have an ISDN connection with T-Com and have selected T-Online as your ISP.

You have configured two ISPs:

1. Internetaccess over ISDN. The PABXsystem willuse anISDN dial-upconnection and the PPP protocol. Enteryour access data (mark theISP inthe list,field »Edit«,field »Accessdata forT-On

line«).

2. Internetaccess using anInternet-by-call provider.The PABXsystem willuse an ISDN dial-up connection and the PPP protocol. Enter any other required data.

When the configuredtime period (interval)expires the PABXsystemattempts tosetup an Internetconnection as of

ten asconfigured in the field »Connection attempts«. Youcan define the time between attempts under»Connection attempts« »Interval«under the configuration item »Network«»Internet«, »Internetaccess«. You can set the»Num

ber« for each ISP that has been configured.

After that, the PABX system will use the next ISP configured in the list for attempting to set up a connection.

If theconnection isdisrupted andan attemptis tobe madelater tore-establish theconnection, thiscycle isrestarted beginning with the first entry in the list.

Firewall

When youuse NAT, the PCs connected to the PABXare well protected against attacksfrom the Internet. Here, your PC is notlinked directly withthe Internet, butconnected via theISDN router integratedintothe PABXsystem.Inter

nal IPaddresses are not passed on to the Internet. The ISDN router carries out the transfer to the Internet and distri

butes the incoming data packets in the internal system. Your PC is protected from attacks from outside.

If you wishto haveadditional security youcan also usethe integrated packageFilter Firewall. Afirewall actsas a logi

cal wallfor data packets between theInternet andthe ISDNrouter which has »holes« for certain packets(firewall ru

les, also known as filters), allowing these packets to pass through the wall.

In the default setting the firewall is active only with a minimum ofprotection (Netbiosfilter). Thisfilter preventsthe forwarding of Netbios name queries from Windows PCs to the Internet. As the names of the Windows PCs are not known in the Internet, it is not meaningful to establish an Internetconnection for forwardingthe name query. This could result in considerable costs, as these name queries occur frequently, meaning that the Internet connection would practically never be terminated.

Note The defined filters of the Filter Wizardhave been configured based onour latestknowledge. Wecan, however, pro

vide noguarantee for the function of the filters.Use of a firewallshould gohand in hand with useof virus scanning software on all your PCs!Firewalls andvirusscanners coverdifferent areas ofdata securityand are anideal compli

ment to one another, but can not replace one another.

After youhave configured the PABX system and are ready tosend datato the PABX, a message will beissued notifying you thatno otherfilter is currentlyconfigured exceptfor the NetBIOSfilter. Youthen have todecide whetheryou wish to configure the full protection provided by thefirewall (recommended), orwhether you wishto send thedata to the PABX system as currently configured.

The filters are described byrules whose configuration requires expert knowledge about the TCP/IP protocolfamily. The firewall of your PABX system can be easily configured using a Filter Wizard in which you need to indicate (in plain text) whether you wish to allow defined applications access to the Internet.

We recommend configuring the firewall filters with the aid of the Filter Wizard to ensure configuration(s) appropriate forand compatible to the applicationsbeing used. These filters provide protection against data packets from the Internetthat may resultin youbeing charged for certain connections.The functionfor the“Automatic connecti

on setup”,for example,may otherwise not always be ensured. A port scan from the Internet (usually the initialstage of ahack attack)may sometimesoccur; thetelephone systemfirewall then replies to this scan with »Reject packets«. But this may nevertheless result in data traffic that prevents automatic setup of a connection.

To start theFilter Wizardin the configurationitem »Networkfilters« click the button »FilterWizard«. The following mask is then displayed aftera warning that starting the Filter Wizard will delete all filters that have beenconfigured up to this time:

The Filter Wizard can be restarted at any time to load a modified (edited) configuration into the PABX system. Click the button »Send configura

tion data« to transfer and activate the filters. Af

ter the data is sent the new configuration is acti

vated in thePABX systemand any ongoingInter

net connection is terminated.

Description of the ISDN router functions Firewall

Page 13

The connection is re-established however as soon as a data packet must be routed to the Internet which the firewall lets pass in accordance with its configuration.

Note Note that when you clickthe button »Send«, the entire configuration for thePABX system will be overwritten. It is strongly recommended to read out the configuration for thePABX system andstoring it ina file prior to changing the filter configuration.

We recommend following the instructions given by the Filter Wizard, unless you establish that one of the applica

tions you areusingcannot set upaconnection to theInternet.In this case,pleasecheck whether theFilterWizard has a corresponding filter available.

Please note thatall filtersthat are generatedwith theFilter Wizard arebased onpackets being discarded,with theex

ception of those for which anappropriate rule exists. The more filters you configure for the PABX system, themore computing time is required for processing of these filters. This could slightly reduce the maximum achievable data throughput rate for the PABX system in some cases.

You cancall up instructionsfor manualconfiguration ofthe firewallfilter rulesusing the button »Help« inthe confi

guration dialog »Filters«.

Portmapping

You wishto accessyour PC from an externallocation viaInternet. Normally, access via the firewall shouldbe prohibited. When youuseport mapping, accesstoanISDN router portthatyou have enabledispermitted from anexternal location. The ISDNrouterthen forwards theaccessrequest to thedefinedport of thePC in thenetwork. When thePC returns data packets the IP address and portnumber of thePC are replacedby the ISDN router with the number for the port mapping port and the router IP. For “outsiders” on the Internet it then appears as though there is only one connection to the ISDN router.

Note Please note that when you use port mapping the firewall for the ports enabled for this function is ineffective. The target PC may then be susceptible to any potential attacks.

Port mapping is practical when you wish to run a game server on your own, for example.

Youcan make thisserveraccessiblevia the Internettootherusers.

Or, if you require certain peer-to-peer file sharing software that provides greater download band

width.

Costs for Internet connections

The PABX can store up to 500 call data records. This data is not lost in the event of a loss of power.

The PABX system also generates a call date record for connections made by the ISDN router. The call data records contain detailed information about the call. Forex.: Dateand time,duration of call, number ofcaller andof theparty called, type of connection, call costs and number of bytes sent and received.

Please note that only the network service provider is authorized for binding connection/call cost logging.

Information about data security when surfing the Internet

You should use a virusscanner on all LAN clients to protect yourpersonal data. Useof this type of software is indis

pensable for safeguarding personal data.
