Product description
1. Product description
OfceMaster Gate is a family of hardware controllers designed for Unied Communications applications. More
than 20 years of work experience by Ferrari electronic have own into the construction. Hereby the acquired skills
in the elds of active Fax/ISDN cards and networking Fax/SMS/voice mail solutions played a major part. The rm-
ware of the intelligent controllers has since then been signicantly extended and improved. Versatile scenarios are
supported:
Fax, SMS and voice mail services are supported for different operating systems when combined with the Unied
Messaging Software OfceMaster.
OfceMaster Gate can be used as a phone gateway to link ISDN-Private Branch Exchanges (PBX) or Trunks to
Microsoft Exchange Server 2007/2010/2013 UM, Ofce Communications Server 2007 and Microsoft Lync Server
2010/2013 in order to integrate their Unied Communications functionalities.
Those functionalities can be combined as well.
OfceMaster Gate is connected to the voice network via ISDN Basic Rate Interface (BRI) respectively ISDN
Primary Rate Interface (PRI) ports. An overview on all possible combinations can be found in the chart below.
OfceMaster Gate stainless steel box is always usable as Unied Messaging Controller or Gateway. There also is
a cheaper version of the larger PRI edition, solely for telephony (“UC”-edition). If need be those can be enhanced to
full functionality afterwards by purchasing the required licenses. All versions of the product can be set up at ISDN
main ports as well as on phone PBX’s.
By purchasing licenses OfceMaster Gate can be extended by multiple ports and functionalities.

Product description
1.1 OfficeMaster Gate: ISDN-Controller and Media gateway
Through the various scenarios of use different versions of OfceMaster Gate were developed. In this part Of-
ceMaster Gate products are described that function as independent Gateways respectively Controllers. (Apart from
that there are versions of boards that are described later on.)
No additional software needs to be loaded into the box. All of the linux based rmware is placed in the ash drive
and loaded into the RAM for execution when booted.
Operated on a PBX (resp. Point-to-Point protocol), Ofce Master Gate acts similar to a PBX, meaning it sup-
ports direct inward addressing and allows automatic assigning of calls (fax, SMS, voice mail and phone) depending
on different dial through numbers.
OfceMaster Gate complies with the specications dened by the ITU for fax group 3. Apart from the compul-
sory transmission with 4800 and 2400 bps, 9600 resp. 7200 and 14400 resp. 12000 bps are possible too.
For fax transmission dened one and two dimensional modes of compression MH, MR and MMR as well as the
error correction mode (ECM) are supported.
Alternatively or simultaneously OfceMaster Gate can be used as a media gateway for Microsoft Exchange UM,
OCS 2007 (incl. R2) as well as for Microsoft Lync Server 2010.
1.1.1 OfficeMaster Gate stainless steel box for Basic Rate Interface (BRI)
The BRI editions of OfceMaster Gate run a powerful 32-bit microprocessor. No additional software needs to be
loaded into the box. All of the linux based rmware is placed in the ash drive and loaded into the RAM for execu-
tion when booted. Because of the autonomy of the system, the UM server is supported by the controller, keeping
the strain to a minimum. No settings via jumper are needed for the hardware, making installing, implementing and
if needed replacing very simple

Product description
OfceMaster Gate for BRI can use both channels of a line simultaneously. The controller supports Euro-ISDN
(EDSS1) and works on a multiple device line as well as on the system line. OfceMaster Gate is also usable for
subsystems and supports some performance characteristics of the TK system protocol QSIG (Q-Interface Signaling
Protocol).
OfceMaster Gate can either be plugged in with the included power adapter or, if supported in the network ac-
cording to 802.3af, be supplied via Power over Ethernet (PoE).
Note!▼Are both power supplies enabled, the power adapter is used. Hereby it is strongly
recommended to first plug in the mains power supply and after that the Eth-
ernet connection. A switch of power supplies is to be avoided while booting.
1.1.2 OfficeMaster Gate for Primary Rate Interface (PRI)
OfceMaster Gate for PRI is shipped in a 19“ case. This case holds a PC Mainboard. The PRI adapter is included
in form of a PCIe board.
Image 1.2: OfceMaster Gate 19“ version
OfceMaster Gate for PRI (19“) can use all 30 to 60 (respectively 120) channels of a line simultaneously. The
controller supports Euro-ISDN (EDSS1) as well as important features of the TK system protocol QSIG (Q-Interface
Signaling Protocol).
1.1.3 OfficeMaster Gate UC
For the use as a Media gateway for Microsoft Exchange 2007/2010/2013, Microsoft Ofce Communications
Server 2007 R2 and Microsoft Lync Server 2010/2013, specic versions of OfceMaster Gate are available, which
are not supported on delivery.
By subsequently adding additional licences, channels for the selection of OfceMaster Software for fax, voice
mail and SMS can be enabled step by step.

1.2 OfficeMaster Survivable Branch Appliance (SBA)
With Microsoft Ofce Communications Server (2007/2007 R2) it was for the rst time possible to use a central
installed OCS at a remote branch. This cost-efcient solution had the drawback that in case of a WAN failure the
whole telephony at that specic branch would fail.
Image 1.3: Solution scenario with OfceMaster SBA
Microsoft Lync Server 2010 was the rst version that supported remote site telephony even on WAN outages.
Microsoft has dened an appliance type of products containing all functions needed for telephony in a branch of-
ces; therefore called “Survivable Branch Appliance” (SBA). The same holds true for the new Lync Server 2013
which also offers a compatible SBA product.
„OfceMaster SBA“ is based on high quality industry grade server hardware which runs Windows Server 2008
R2 together with Microsoft branch ofce components like Registrar and Mediation Server.
A separate PCI-Express card contains the complete media gateway which supports different types of ISDN con-
nections – four basic rate interfaces (BRI) supporting 8 ports and up to 60 channels of E1/T1 primary rate (PRI)
connections. Four analog FXS ports are available through an additional low prole PCIe card. If more ports are
needed, separate external devices can be added. In addition, support for SIP trunks and legacy telephony devices are
available as well. The gateway board is recognized by the hosting server machine as a standard network interface
card – all gateway functions are completely off-loaded from the main CPU.

Product description
The same hardware can also be used as a Basic Hybrid Gateway for Microsoft Ofce Communications Server
2007 R2 which can be upgraded to a Survivable Branch Appliance later.
1.1 Functionality and Connection
1.2.1 One product – multiple possible applications
For the use as gateway for Exchange 2007/2010/2013 / Ofce Communications Server 2007 (OCS/OCS R2) /
Microsoft Lync Server 2010 as well as when used as Unied Messaging Controller, it is necessary to obtain certain
information about the caller. The called number and potential carried out call forwarding need to be evaluated in
order to nd the appropriate way of processing the call.
When used as Gateway and Unied Messaging Controller at the same time, it is to be decided whether an incom-
ing call is meant for Exchange, OCS, Lync Server or the OfceMaster Messaging Server. This calling information
is provided on each call via the ISDN-D-Channel-Protocol. Depending on the different telephone system, the depic-
tion can however vary. To ensure uniform depiction for the further use, an extremely capable call number analysis
and call number correction has been integrated into OfceMaster Gate.
Inherently, OfceMaster Gate is installed on a telephone system or a trunk line via ISDN and is able to process
incoming calls. For those calls OfceMaster Gate decides whether or not to take the call, upon the routing (by which
instance, for example Exchange 2007/2010, OCS, Lync Server or OfceMaster, the call is to be handled) and upon
the replacing or respectively modifying of call information (which call information does the processing instance
expect at what point).
Through additional functions provided by OfceMaster Gate for Microsoft UM/UC solutions (Exchange, OCS,
Lync) and through the double functionality as controller for the Unied Messaging System OfceMaster, relatively
complex settings for calling numbers can be required. The conguration of usual cases of application is therefore
possible via a very simple dialog, while more complex settings can be made via exible rule-table in the advanced
mode. It is possible to switch between advanced and simplied mode. In the simplied mode created congurations
are internally converted into rules and can be looked at in the advanced mode.
1.2.2 Connection to Exchange 2007/2010/2013 UM
In the following, the processing of incoming calls in Exchange UM is described. The phone number of a par-
ticipant, who has been activated for Exchange Unied Messaging, is saved in the Active Directory as a EUM-
(Exchange Unied Messaging) address. For incoming calls, the participant is identied via this phone number. Has
the participant set up call forwarding to the so called Pilot-ID of the Exchange UM on his connection, the incoming
call is redirected. The calling number of the participant is in that case provided as Redirecting Number (Redirected
Number; in SIP-Protocol: Diversion Header). With this information, Exchange determines the partaker and starts to
play the welcome message to the called to, if applicable, record a voice mail.
Is the incoming call a fax, OfceMaster Gate will automatically note this and in interaction with Exchange ac-
tivate the fax function.

7
www.ferrari-electronic.com
Product description
The welcome message will also be played, should the participant call his own redirected line from a different
phone, for example his mobile phone. Through the appropriate key input („*“-key), Exchange can be set into the
remote query mode where the called will be asked to identify himself via his PIN.
No redirecting number is available should the participant, for remote query purposes, directly call the Pilot-ID
of Exchange UM, because no redirecting occurs. In this case Exchange will ask for the Voicebox-Number (meaning
the redirecting path) of the participant for identication and afterwards for the PIN for authentication. Therefore, the
fax function of the calling number of the participant will only occur when the connection is redirected. OfceMas-
ter Gate provides ways to work around this signicant limitation and enable the fax function permanently without
having to keep a separate dial-through number as EUM ¬address for fax. Detailed information for this can be found
under „conguration“.
1.2.3 Use as media gateway for Lync Server 2013/2010
An important use of OfceMaster Gate is as phone gateway for Microsoft‘s UC-systems. The Gateways passed
the necessary certication tests for those systems and can therefore be used restrictive free - both as stand-alone
Gateways and in combination with the OfceMaster software, using the hardware and ISDN-ports together for all
communication services (Fax, SMS, voice mail and telecommunication).
The communication can optionally take place encrypted (SIP/TCP, RTP) or not encrypted (SIP/TLS, SRTP).

2.1 ISDN Port
An important use of OfceMaster Gate is as phone gateway for Microsoft‘s UC-systems. The Gateways passed
the necessary certication tests for those systems and can therefore be used restrictive free - both as stand-alone
Gateways and in combination with the OfceMaster software, using the hardware and ISDN-ports together for all
communication services (Fax, SMS, voice mail and telecommunication).
The communication can optionally take place encrypted (SIP/TCP, RTP) or unencrypted (SIP/TLS, SRTP).

Located left and right below the BRI port of OfceMaster Gate are two LED‘s. These are triggered by the rm-
ware of the controller:
• The right hand side LED is triggered, when layer 1 of the ISDN protocol is activated.
• The left hand side is triggered, when the in-build ISDN terminating resistors are triggered via the congura-
tion program.
Note!▼In older versions of the hardware, the left hand side LED is triggered, when the
terminating is turned off! In all cases though, the settings in the configuration
program apply.
Should an additional ISDN device be connected to the same BRI as OfceMaster Gate it is mandatory that the
ISDN port is declared as a multiple-device-port (point-to-multi point). When used in parallel connection, Ofce-
Master Gate and others connected to this line need differing MSN (Multiple Subscriber Number) to be assigned to
them. Is the ISDN line in point-to-point mode, no parallel connection is possible.
2.2 Network Integration
OfceMaster Gate is addressed by the OfceMaster Server-Software or, if used as media gateway, via the net-
work. The Server-Software in this case is the component OMCUMS of the messaging server.
OfceMaster Gate and OMCUMS communicate via TCP/IP. For this, they need to know each others IP addresses.

10
www.ferrari-electronic.com
Installation
If used as media gateway, the communication with Microsoft servers occurs in the same way.
To make this possible, every OfceMaster Gate is in need of a tting network address. Possible ways of ensuring
this:
with DHCP server
OfceMaster Gate in delivery condition (standard, even after resetting) receives its IP¬ conguration from the
in the network existing DHCP server. Via a DHCP server, IP¬ addresses and the Domain Name Server (DNS) are
assigned to computers in the network.
In OMCUMS, the IP-address of OfceMaster Gate is manually declared.
The uniqueness of the IP-addresses is ensured and an address conict ruled out, because only one side requires
a manual entry.
without DHCP server
Is no DHCP server existing in the LAN or is the existing DHCP server not assigning an address to OfceMaster
Gate (because he for example is out of valid addresses), then OfceMaster Gate will after a while automatically
assign itself a private address (a so called Zeroconf-Address, also called APIPA-method). This address allows the
activation of the build-in network interface, to ensure at least the availability via UDP broadcast. For the normal use
however, in this case a static address will have to be assigned.
The program OfceMaster Gate Conguration (OfceMasterGateCong.exe) is used to nd OfceMaster Gate
in the network. By clicking the correct button, sub network wide search for OfceMaster Gate is started via UDP
broadcast. Sub network in this case is the physical network, in which the computer with the IP conguration pro-
gram is integrated. This sub network is usually restricted by network routers, for example rewalls, that do not
redirect the UDP broadcast.
In order to assign an address to OfceMaster Gate, Ofce Master Software either uses an distinct IP address or
the resolved name.
If OfceMaster Gate, as described above, is used as DHCP client, than it should be ensured, that OfceMaster
Gate is available under the same IP address after reboots, so that the Server-Software can continue working properly.
Possible ways of ensuring this:
At the DHCP server, an IP address is reserved for the MAC address of OfceMaster Gate. This way, OfceMas-
ter Gate receives the same IP address after every reboot.
In the OfceMaster Server Software, instead of the IP address, the resolved name is congured. Now when the
DHCP server automatically refreshes the DNS server, OfceMaster Gate will still be reachable by the Server Soft-
ware, even after having been assigned a different IP address.

Separate Y-cables are available if all 4 BRI ports are to be used – the rst 2 BRI ports can be utilized using stan-
dard ISDN-cables.

Image 2.2: Detailed view of Media Gateway Board
The Primary Rate Interface (E1/T1) is implemented in a FPGA (Field Programmable Gate Array), which con-
tains additional support algorithms. It can even be upgraded in the eld to implement more features as needed!

2.3.3 Analog Card – 4 Port (FXS)
Four analog ports are contained on a separate low-prole PCI-Express Card connected to the main gateway
board using a at ribbon cable.
Image 2.3: Analog Card
The cable transports audio signals through a TDM bus as well as separate control information. High quality
faxing is possible since no VoIP technology is involved between PSTN and FXS ports.
2.3.4 ISDN and Analog Interfaces
Positions of analog and digital interface connectors are shown in this picture (rear view):
Image 2.4: Interfaces of the OfceMaster SBA
For BRI ports a separate Y-cable must be used if more than two BRI lines are needed.
Note!▼Never use PRI 2 without PRI 1 – if only one PRI interface is connected always use PRI
1, otherwise clock synchronization will not work!

Note!▼If BRI interfaces are used in the US, a separate FCC approved NT1 Network Ter-
mination Unit must be installed to connect to OfficeMaster SBA S/T BRI ports.
For LAN-connection, please plug in the network cable into the upper interface
(LAN1):

2.4 Recovery
2.4.1 Survivable Branch Appliance
Use of the Recovery USB Stick
The SBA system software can be reset to factory settings at any time by using the USB recovery stick.
Please follow these steps:
1. Connect the SBA device to Keyboard, Monitor and Mouse, either physically, using KVM or through tools
like HP ILO
2. Plug the USB stick into the front USB port
3. Power up SBA, it will automatically boot from the USB
4. At the end (message: press any key to shutdown computer) press a key
5. Remove USB stick
6. Power up SBA
7. Set the local Administrator password to OfceMaster!
8. Check network interface conguration (see below)
9. Open a cmd console and enter the following commands: %systemroot%\system32\inetsrv\appcmd.exe set
APPPOOL omsba_admin_pool -processModel.userName:ofmadmin %systemroot%\system32\inetsrv\appc-
md.exe set APPPOOL omsba_admin_pool -processModel.password:Sefte25AuTib
10. Now the deployment Web UI is ready for use

Note!▼When a SBA is shipped, the serial number of the embedded gateway board is al-
ready preconfigured. After using the recovery image, the gateway serial number
will be queried later by the Web UI during deployment. The serial number of
the gateway board can be found on a card, which can be pulled out at the front
side:
Image 2.6: In this example the number to be entered is 259 (last 5 digits without leading zeros). (On some models, the number may be hand-
written and may contain the serial number only, without the prex, e.g. 234).
Check of the network interface configuration
During deployment of the Windows image via USB stick, the desired network conguration is automatically
established:
