1. INTRODUCTION OF GATEWAY DIAL-112
DIAL-112 is a device that redirects voice telephone calls over the GSM network allowing a
significant reduction in the cost of calls to mobile telephones by, for example, negotiating corporate
contracts. DIAL-112 gateway is available with 1 or 2 GSM modules (1-2 SIM). In this manual, will
be described the 2 GSM modules version. Users of the 1 GSM module version will not be able to
use the features available on the second GSM line.
The unit has a NT port for ISDN attach and double GSM module. Using DIAL-112 as the default
output interface for all calls directed to one or more telephone prefixes selected by internal
exchange (or mobile network prefixes) is obtained to address to the GSM network all the calls
coming by the two channels of the fixed line directed to mobile phones: DIAL-112 uses the GSM
modules to contact the user of mobile network and connect it inside the caller internal extension of
PBX. This will exploit the greater convenience of GSM network than fixed calls to mobiles.
If the PBX is provided with advanced routing functionality (LCR - Least Cost Routing) it is possible
to configure the relevant table (ARS - Automatic Route Select table) in a way that DIAL-112 is
chosen as the default output line for calls directed to one or more mobile GSM numbers,
depending on their prefixes. If the PBX has no LCR function, a dial code for the DIAL-112
connection can be prefixed to the telephone number normally called, so as to use DIAL-112 as an
outbound gateway. Moreover, DIAL-112 has an internal LCR mechanism that allows the selection
of the GSM module to use depending on the prefix of the called number.
For incoming calls, i.e. for calls to the SIM number of the built-in GSM module, DIAL-101A redials
the calls downstream the PBX, forwarding the caller identity (CLI). It is also possible to use
advanced features for calling management as the Smart callback function: in the case of an
internal PBX’s extension has placed a call attempt failed to a mobile phone, any request by the
called mobile phone will be transferred automatically from DIAL-112 into the PBX, and then directly
to the person who had originated the first call.
The unit connects directly to an ISDN BRI free PBX’s urban line attack (ISDN BRI T0). It can also
be used in processes where there is no access to the public telephone network (i.e. sites and
places decentralized). Calls to the GSM network does not pass from the basis of the fixed network,
thus leaving these possible resources always available for any incoming calls to the company. In
fact it is like to add two more lines in the PBX, used, for example, only to dial GSM network
numbers.
DIAL-112 can perform additional functions as two alarm contacts inputs: it is possible to be notified
via SMS (customizable) after alarm activation.
DIAL-112 is easy to install and connects to the programming PC via an USB port. For the
programming is not necessary to install any software, just a normal terminal emulation software
(such as HyperTerminal
™
for Windows
®
), and its installation is very simple and quick and requires
no special knowledge.
DIAL-112 can also be programmed with DTMF tones, locally reaching the ISDN attack of PBX or
remotely via GSM.

Services for outbound calls (converted from the wired line network to GSM)
DIAL-112 allows making direct calls to cellular telephones using the GSM network, which is
more cost-effective than calling from a wired line. Moreover:
• Call by call conversation timeout with time recharge option
• Table for inhibiting outbound calls to complete unwanted numbers or to unwanted prefixes,
possibility to inhibite all the outbound calls, so all inbound calls will be privileged.
• Possibility of SIM identity hiding of the GSM modules to the called number
• Possibility of counting minutes of traffic for outgoing calls, with the possible blocking of
outgoing calls following to the end of credit or sending SMS text alerts
• Access to the module for local programming via DTMF
Services for inbound calls (converted from GSM to wired line)
DIAL-112 receives calls from the GSM network and reroutes them to the PBX (or telephone) in
wired line ISDN mode. Moreover:
• Possibility of rejecting all incoming calls or anonymous incoming calls
• Table for inhibiting unwanted callers (rejecting incoming calls)
• Sending the caller-ID (CLI) to the downstream ISDN device
• No timeout on incoming calls
• Access to the remote programming via DTMF
Additional functions
• Smart callback: for the automated diversion of the call back to the PBX’s internal
extension (outgoing calls)
• SMS callback: similar to the previous service, the caller that have not reply or is busy will
receive a SMS with predefined text
• GSM module selection: depending on the chosen B channel of the ISDN BRI line
• Alarm contacts: 2 contacts of external input for Alarm / Remote Notification service via
SMS
• Output contacts: 2 internal relays contact for remote control of low power devices, in
impulse or stable mode (future implementation)
• CLI-based automatic routing service: Service to automatically route the caller based on
his CLI to an internal extension target

6. INSTALLATION AND DIAGNOSTICS
DIAL-112 has two GSM modules that require 2 SIM cards from the telephone operators to work.
The procedure for registering the SIM card on the wireless network when the device is turned on is
automatic and identical to that of a normal GSM telephone.
6.1. Installation of the DIAL-112 unit
In addition to resting on table, a desktop or shelf, the DIAL-112 unit can be wall-mounted, using the
appropriate slots located on its rear panel.
To do that proceed as follows:
• Attach the DIAL-112 to the wall, with the antennas connectors facing upwards.
• Manually screw the antennas connectors (do not use a wrench).
• Connect the ISDN cable from the “TE-Pbx” port to the ISDN port of your PBX (or to a self-
powered ISDN phone).
• For each GSM module, insert the SIM card.
To insert the SIM card into DIAL-112, use a small screwdriver or pen point to press the
centre of the yellow button on the front slot with the SIM holder. Remove the holder and
insert the SIM with the gold contacts facing upwards. Note that there is only one correct
way to place the SIM in the holder. Now, carefully align the holder in the slot and insert it
until it stops in its operating position.
Note
To avoid damaging DIAL-112 or the SIM card, make sure the unit is disconnected from its
power supply before inserting or removing the SIM card.
Important tips for proper operation
We recommend disabling the PIN code request, voice mail, all call diversions (such as
when busy, absent or not available) and call notifications on the SIM card before inserting
the SIM in the DIAL-112, using a normal GSM device with keypad.
• Connect the power supply cord.
6.2. Connection modes
ISDN is a digital system in which communications between various devices must be synchronized
with a common clock. Some PBX (including Alcatel, Ericsson, Philips, Selta, Siemens) can not
tolerate a lack of synchronization between different TE ports.
If you use a PBX with these characteristics is necessary to connect an output of NT at "Sync-NT"
input of DIAL-112 in order to keep the DIAL-112 clock synchronized with other present devices on
NT ports. To connect, use a cable with only 2 connection wires inside (only the RX to the device).
In the diagrams on the following pages are presented several solutions for connecting where are
highlighted the connections and the possible source of signal synchronization.
For the sole purpose of synchronization, DIAL-112 must be connected to a normal NT port, in
order to receive the same clock that the NT port sends to the PBX and on which the PBX
synchronizes (showed in the images with a dotted line).

TEMA TELECOMUNICAZIONI SRL GSM Gateway Interface DIAL-112
MAS-DIAL112-REV06EN Page 11 of 35
Connecting device as NT (ending) and synchronization from NT port
This method of connection requires that DIAL-112 is related to an external ISDN line (ISDN port
TE) of the PBX: in other words, DIAL-112 has the same role of a new NT port. From the
perspective of the PBX, there is no difference between the external lines available, and between
one or more BRI lines existing and the new BRI attack system offered by the DIAL-112 that goes to
be installed.
From the "Sync-NT" connector, DIAL-112 is limited to receive the clock synchronism therefore
does not affect in any way traffic between the NT and the PBX. Please note that the ISDN system
provides the Point-Point and Point-Multipoint variants. To function properly, DIAL-112 must be
configured in the same way as the TE port of the PBX connected to it, and set appropriate fields on
the form PTMP PTP in the “General Parameters” mask of the configuration of the device.
Nota 1 If there are multiple ports in the installation, use the sync one of the existing ones that is
configured as Point-to-point, in order of priority from the following:
1. derive synchronization from a port with Point-to-point setup, on which the disabling of level 1 of
the Protocol ISDN does not happen;
2. derive synchronization from a port with Point-to-point setup, configuring the PBX maintaining
always-on the level 1 on this line;
3. If no described above link type is available, obtain the synchronization from the port that made
the most traffic. This will reduce the chance that the port turns off wasting synchronization while
other lines (and their ports) are active.
Nota 2 If more DIAL-112 are connected to the PBX, make sure that all are synchronized to the
same NT port or S0 bus of the plant. If the customer has NT port (for example, has a PRI) and no
S0 free output to use any of DIAL-112 to synchronize the others (take in parallel the central wires
of the TE-PBX port of the first device and connect them to the Sync NT port of the others).

on the internal attack.
6.3. Operational and diagnostic indicators
When DIAL-112 is correctly connected and powered, the LEDs signal the status of the system in a
simple, effective manner. For each GSM section, the yellow LED “GSM” has diagnostic purposes,
and the way it blinks depends on the GSM engine onboard (see next page for details). The built-in
modules now will registrate itself to the GSM network.
6.4. Diagnostics LEDs
On power-up, the two red LEDs “On” flashes quickly for a while: it means that the device is booting
correctly. After this short time the flash will slow down and, after the correct machine boot, the two
LEDs will flash slowly every 3 seconds (stand-by status of the lines).
The use of the telephone line will be indicated by a faster flashing of the red LED; the flashing is
quicker during the call and, during the conversation the red LED remains lit. At the end of the call,
the flashing will slow down.
The two yellow LEDs are used to monitor the status of the GSM modules. During the registration
phase or in case of absence of SIM card, the yellow LED remains lit. After the correct registration
to the GSM network, the yellow LEDs will flash slowly. During a call, the yellow LED will flash
quickly.
The gateway is ready to be used when connected to the ISDN line and when the registration to
GSM network has been made. Make an incoming and an outgoing call to check communications in
both ways.
In summary, meaning of the LED "Line" (red):
Slow flashing Line in stand-by status, no active calls
Quick flashing Taking a line from the PBX, the device expects the numbers to make
the call
Very quick flashing Call in progress, waiting the reply by the called number
Lit Conversation in progress
4 very quick flashing One of the SIM has exhausted the credit and the system has blocked
the ISDN line so there are not allowed more outgoing calls

TEMA TELECOMUNICAZIONI SRL GSM Gateway Interface DIAL-112

Meaning of the LED “GSM” (yellow):
Slow flashing Stand-by status of the line, SIM correctly registered and no ongoing
conversation
Quick flashing Call or conversation in progress
Lit SIM not inserted or not yet registered
6.5. PC connection
The following describes the phase of preparation to program the system. First, once powered on
the system and connected via the USB cable (included) that comes with a free USB PC port,
Windows
®
asks if you want to download the latest drivers for the new device detected (in the
following pages and figures will be next steps Installation on Windows
®
XP
®
, regarding Windows
®
2000 the process is very similar):
At the request for access to Windows
®
Update, select "No, not this time" and press "Next" to
continue.
Choose to install from a list or specific location and press "Next".

TEMA TELECOMUNICAZIONI SRL GSM Gateway Interface DIAL-112
MAS-DIAL112-REV06EN Page 14 of 35
Make sure you have inserted the supplied CD in the CD-ROM reader of your PC, set the option
"Search removable media” and click "Next". Windows
®
will find a suitable driver to install:
Pressing "Finish", you will be prompted to install the driver for the virtual serial port:
This phase is simpler because just leave selected "Install the software automatically". Press "Next"
and finish the installation.

TEMA TELECOMUNICAZIONI SRL GSM Gateway Interface DIAL-112
MAS-DIAL112-REV06EN Page 15 of 35
Now, a virtual serial port has been added to your system. Since the device is not equipped of a
video or a keyboard, for programming is necessary to connect to the new COM port a terminal
ANSI emulator set at 115,200 BPS. There are many programs on the market that allow such
operations. The following describes how to configure the terminal emulation program called
HyperTerminal
™
, provided as part of default in all versions of Windows
®
from Windows 95
®
(but no
longer supplied with Windows Vista
®
).
To configure the program to our purpose, select from the toolbar, the voice HyperTerminal
™
from
accessories menu.
The next screen asks you to create a new connection, similar to the following:
In the Name field, type the identification of the connection, for example “tema”, and confirm with
<enter>. It might be asked to configure the modem, in this case no answer.

TEMA TELECOMUNICAZIONI SRL GSM Gateway Interface DIAL-112
MAS-DIAL112-REV06EN Page 16 of 35
Finally, the program asks you to configure your connection. In the "Connect" click "directly to
COM1" (or COM2, 3 ..., depending on the virtual serial port driver installed on your PC).
Confirming with OK, is now being asked to configure the port:
Select “None” in the "Flow control" (speed – Bits per second is not important):
If everything was done correctly, confirming by the OK button and pressing <enter>/<esc> few
times, then the main form of DIAL-112 will appear. If the mask appears to be confused, because of
used characters of program's emulation, please choose the option "Character" from "View" menu:
From the selection mask choose the font type "Terminal" and size 9 or 12 (a small font generates a
small mask on screen, a large font will be readable but on weak screen resolutions the mask may
not be fully displayed on the screen).
Now the program is ready for use. Closing HyperTerminal™ is required to save the connection:
answering "Yes", the subsequent opening of the program simply makes the connection that was
previously saved to connect again. See below, in Chapter 8 for details related to programming from
the PC.

7. SERVICES
7.1. Outbound call gateway
In its basic function, through the urban attack of the PBX connected to DIAL-112, you make
outgoing calls using built-in GSM modules by transforming a call from fixed line to a GSM one. The
service must be explicitly enabled by the "Enable outgoing calls" in the mask of programming
(active by default).
Lifting the handset of the connected ISDN device or engaging DIAL-112 through the PBX, you
heard the DIAL-112 invitation tone to select.
Then, type the phone number to call within the configurable time to select (field mask programming
"Interdigits", default 6 sec.).
DIAL-112 must gather all the digits of the number to call before making the call itself through its
internal GSM module (as it does with a normal GSM phone) using a configurable timeout
("Interdigits", default 6 sec.). So, after the last digit in the composed number, it must pass this
timeout before the call will be generated to the GSM network.
DIAL-112, however, send the call without waiting time for interdigit after receiving a number of
digits (the area of mask programming "Max digits", default 10), unless the number is not preceded
by the international prefix 00, in which case the device always waits for the expiry interdigit time
before making the call (since it can not know the actual length of the number to call). It is possible
to speed up the call of numbers consist of fewer digits simply by pressing the “#” (pound) at the
end of the number to call, to tell DIAL-112 to proceed immediately to connect to GSM network.
While sends the call to the GSM network, DIAL-112 may send the caller a special multitone
reporting to indicate to user that the call is being generated. The user can verify, for each call, the
actual use of DIAL-112 for calls planned. This service is subject to the parameter "Ringing tone": If
you do not want this alert, you can disable it in the form of programming.
After sending the call, DIAL-112 connects your phone to allow the caller to hear reports on the
progress of the call itself (free, busy, etc.).
It is possible to hide the identity of the SIM, simply activating the appropriate field ("Hide caller");
see 8.1 later in the manual. This approach is effective for all calls. Wanting to choose whether or
not to mask the identity of the SIM per-call basis, regardless of the programming of the system, the
GSM network allows the sending of force or masking the CLI using special codes from universal
add to the number called. The codes are:
CLI FORCED FORWARDING *31# + GSM NUMBER
CLI FORCED HIDING #31# + GSM NUMBER
To keep the modules GSM always available to make outgoing calls, is that it is possible to block
any incoming calls: DIAL-112 will refuse any incoming calls without answering.
If the PBX is equipped with advanced routing (LCR - Least Cost Routing), you can configure the
table (ARS - Automatic Route Select table) so that DIAL-112 is used as a general default output for
direct phone calls from internal PBX phones to one or more mobile telephone line prefixes.
If the PBX does not have the function of LCR, you can set a code selection where the DIAL-112
ISDN attack is linked, before the phone number every time you want to use DIAL-112 as an output
gateway. See the documentation of your PBX for more information on these advanced features.
It is also possible to activate the "Prepaid Traffic” service. In this mode, the system takes no
account of the real credit on the SIM Card (service not offered in a simple and uniform way by the
GSM operators), but count the minutes for outgoing calls (taking advantage of any promotions or
contracts providing for a certain number of free minutes to all or particular numbers).

7.2. Inbound call gateway
In its basic function DIAL-112, when receives a direct call to internal GSM module, diverts the call
to the PBX ISDN line; if you receive the caller identification it will be send by DIAL-112 to PBX so it
can appear on the phone display. After the answer, the caller and the called are in communication.
There is no timeout for incoming calls. Optionally, you can activate the DISA service (similar
service found in many PBX): the system does not immediately forward a call to the PBX, but
responds and sends a selection tone to the caller, which can type an extension number via DTMF.
Setting the correct box, it is possible to ignore all incoming calls (the internal GSM module rejects
it). The function is useful for maintaining the system always available for outgoing calls.
Note: This setup has the disadvantage of preventing the system programming by remote call.
7.3. Table of numbers and prefixes
It is possible to enter numbers or area codes or part numbers in a table so that DIAL-112 make
direct calls to those numbers only (see par. 8.3). Any other number will be blocked. If the table is
left empty, it is ignored. Numbers or prefixes in this table are at most 150.
7.3.1. Outgoing calls
It is possible to enter numbers or area codes or part numbers in a table so that DIAL-112 does not
make direct calls to those numbers (see par. 8.3). For example, inserting the value "06" will inhibit
all calls to fixed networks in Rome, entering "02615441" will inhibit direct calls to this complete
number. Entering "144" will be blocked the calls to the italian paying service centers. It is useful for
blocking calls to fixed network (not cheap by using GSM network) or unwanted, when the PBX
does not have the ARS service or to DIAL-112 is connected only a telephone. Enter a specific
prefix, such as "345" and tick the field "Deny", all the numbers that begins with these digits cannot
be called. Introducing the table with the number "3451234567" and tick the field "Allow" will be
done the call to and only to this number, despite the presence of the prefix blocked. So the rule is
that the number allowed take priority over those defined as being denied.
7.3.2. Incoming calls
Similarly as for outgoing calls, the tables fields can be compiled for incoming calls to block or allow
the reception of calls from particular numbers or area codes (see par. 8.3). This function is useful
to discriminate calls from certain geographical areas in the case of numbers from a landline. Very
useful in case of a company with outside staff that constantly moving himselfs that often need to
contact the company. In this situation these phone numbers (added to the table with the field
"Allow" enabled), can call the company, while other generic callers or that do not show the CLI will
be rejected automatically by the system. This creates a kind of preferential channels which
provides a high availability to authorized callers only.
7.3.3. Criteria for the use of the SIM cards inserted in the GSM modules
Automatically, call by call, DIAL-112 can decide which one of the two GSM modules must use. The
choice can be made with one of the following ways: The first free module, through LCR (controls
the first digit of the dialed number and according to them decide which way the call is routed),
alternating, in an equitable manner but the calls duration (allows to distribute traffic to the two GSM
operators or two SIM) through channel B (B1 is sent on GSM module No.1 and B2 on GSM
module No.2; in this configuration, incoming calls also will be presented on the same ISDN
channels). However, if you activate the count prepaid minutes feature, the system will always use
the SIM with more minutes available.
For each module there are four "LCR Prefixes” fields to fill for up to four area codes that govern the
use (see par. 8.2). You can also enable a feature so if the module set through "LCR Prefixes” is
busy, the call can be made through the other module; set the "Use module 2 if busy" for the first

TEMA TELECOMUNICAZIONI SRL GSM Gateway Interface DIAL-112

module and "Use module 1 if busy" for the second. If the dialed number is not covered by the LCR
table of any module, DIAL-112 you still use the first module to allow the call.
7.3.4. CLI presentation service associated to the individual prefixes or numbers
Activating the option "Hide CLIP" in the GSM parameters, the system hides the CLI for all the
outgoing calls to the called number. It is possible, however, in cases where it becomes necessary,
to force the sending of CLI to certain area codes or even to individual numbers of users, selecting
the appropriate field in the table. For example, this is a useful function to facilitate the activities of
users that uses corporate RAM. Those particular users (and only them) that gets the CLI will know
that someone in the company is calling them or tried to reach them. This feature in conjunction with
the "Smart callback" service later described, makes DIAL-112 essential for this type of application.
7.4. DISA service
7.4.1. DISA service as general setting
It is possible to configure the DISA service in the General Parameters so that goes for the whole
system. With the DISA service enabled, will be offered to the incoming calls an inviting tone so the
caller can select the extension that want to achieve.
7.4.2. DISA service associated to the individual prefixes or numbers
Otherwise it is possible to configure this service in a specific manner on a user by user basis. For
example it is possible to deny the DISA service to the general level, but enable it only for some
special calling number (or prefixes). This service has lower priority than the general DISA and
higher priority than the DISA service’s direct association with the number to call.
7.4.3. Automatic routing service
Finally, you can instruct the system to make sure that when is received a call from a specific
number, it is forwarded to the internal extension shown in this field. For example, entering the
phone number of a commercial agent of the company, to each and every call, DIAL-112 recognize
the number and automatically forwards directly to the number of its reference person in the
company. It is often useful to associate the numbers of customers into the company's internal staff
that will give them assistance. The PO does not receive the call so he must not forward the call to
the person or group of reference work. Using the automatic routing in this way, if the extension
number to contact is busy, the external call is hunged up, without charge of costs to the caller.
7.5. Smart callback service
Making an outgoing call through DIAL-112, the called user becomes aware of the number of SIM
inserted in the used GSM module (if you have not enabled the option "Hide caller"). This could be
useful because, in the case of missed call, the called user might want to recall later.
Normally DIAL-112 in its basic configuration, forward this recall to the PO as any generic call. The
smart callback service (see par.8.1) of DIAL-112 instead optimizes the management of callbacks,
sending each of them to the extension that had tried to call that user. In detail, DIAL-112
automatically performs these steps:
• When from the PBX is making a call to a GSM module and it does not answer, DIAL-112 stores
in its own large callback table the association between internal number caller and called.
• When a module receives a call from the GSM network, DIAL-112 verify if the caller is present in
this particular table: in this case consider it a callback call, not forward to the PO, but within
previously written in the table. Immediately after DIAL-112 removes this information from the
table. Thus, subsequent calls from the same number will not be forwarded to a specific
extension.

TEMA TELECOMUNICAZIONI SRL GSM Gateway Interface DIAL-112
MAS-DIAL112-REV06EN Page 20 of 35
• The data in the table are still removed after 12 hours or after filling the table.
For the correct functioning of Smart callback is necessary that the PBX is properly set to send to
DIAL-112 the number of the caller and accept from DIAL-112 an internal extension call, all coded
according to the ISDN standard.
This service is very useful to prevent that the PO receives calls from people unsuccessfully
contacted by a number of the company (one of the numbers presented by SIM DIAL-112) and
recall without knowing the actual internal source of the call: the PO may not have enough
information to properly do the call of its kind, not necessarily aware of the call attempt went
unsuccessfully. The system can avoid this type of situation with the service described above.
7.6. SMS callback service
The service is similar to the Smart callback. When a user does not answer or is busy, you can
send a predefined message to this number (max 36 characters). If the PBX provides the number of
the internal extension caller, it is placed in the bottom of the message (are taken the last n digits of
the outgoing number, depending on the parameter "PBX digits len"). The message could then be
like "recontact TEMA" or "recontact TEMA at the number 123".
7.7. Callback for the incoming calls
This service is appliable for the incoming calls from the network. When the calling number is into
the “Prefix and number” table and the CB flag is enabled (see 8.3) then, when the call hangs up
before the 3st ringback, the system immediately calls back and let him use all the servicse he’s
enabled to. But if he doesn’t hang up, the system will treat the call as a normal incoming call.
This service is usefull to charge the cost of the call to the gateway SIM instead of the caller SIM.
7.8. Alarm contact dialer
The service allows you to send an SMS to one or two GSM numbers as a result of activation of the
contacts for alarms to alert management staff. If the alarm contact is reseted (reopen and closing),
will start another alert.
7.9. Relay contacts remotely operated
DIAL-112 has two integrated relays that can be used for electric drives (see par. 10.2.2)
7.10. Module access for local programming via DTMF
It is possible to program the parameters using the line of DIAL-112 through the PBX trunk
interface. See section 10.1 for the procedure.
7.11. Module access for remote programming via GSM
Call the number of the SIM card inserted in DIAL-112, wait for someone to answer on the
downstream line and in the first 30 seconds of conversation dial ### (3 pound) + programming
password (default is 1111, can be modified by the user, see paragraph 8.1).
