2. INSTALLATION AND COMMISSIONING
The following steps need to be carried out for the commissioning of the MMk-736:
2.1. Installation of the SIM card
Before starting up the equipment, it is necessary to install a SIM card so that it can make calls.
Before installing the SIM card, we should make sure that the PIN has been disabled and
services such as call diversions or voicemails are not activated.
The slot to insert the SIM card is found on the left-hand side of the device, so it is NOT
necessary to open it for the insertion of the card. The gold-plated side of the SIM card must be
inserted downwards and the cut-off corner towards the inside. Then, push it in until you hear a
click.
2.2. Connection of the GSM antenna
Connect the GSM antenna provided in the corresponding SMA female connector.
It is important to find a place for the antenna which offers a good level of coverage, so as to
guarantee good audio quality when making voice calls.
To check the level of coverage, once the equipment has been switched on, inspect the
corresponding status lights (see section 3).
2.3. Connection of the telephone equipment
Connect the home automation/emergency phone equipment to the FXS connector.
IMPORTANT: The GSM gateway MMk-736 is not designed to supply power to emergency phones
that are powered from phone lines. MERak is not responsible for the malfunctioning of the
installed equipment in these circumstances.
2.4. Connection to the power supply
The MMk-736 is powered through the DC 12V frontal connector.
The power voltage of the equipment is 12VDC ±20%.
Connect the included power supply to the device, which complies with the above mentioned
specifications. The use of a power supply different from the provided one may cause serious
damage to the equipment.
2.5. Switching on and verification of proper functioning
Switch on the device using the ON/OFF switch. Check proper functioning by observing the
corresponding status LEDs:

4. CONNECTIONS
The MMk-736 has a group of communication ports that provide remote access to various types of
devices, allowing for it to be monitored and controlled (for more information regarding how to access
these ports, refer to the M2M Communication Manual).
The available connectors and their pinouts are indicated below.
4.1. Power supply
1.9mm DC connector. 12V DC max input.
It is recommended to use the provided power supply with the
equipment.
4.2. FXS (telephone line output)
Terminal block (pitch 5.08mm).
A maximum of four pieces of equipment can be connected
simultaneously.
4.3. GPOs
Terminal block (pitch 3.5mm).
NPM open collector transistor
output. Maximum current in NPN
150mA pins per pin. Maximum
300mA.
These outputs can be activated or deactivated remotely via CSD and/or GPRS connections.
Furthermore, once the equipment is registered in the GSM network, it regularly checks the level
of coverage received. If, at any moment, insufficient coverage levels are detected lasting longer
than one minute, which is blocking a phone call from being made, the OMSL NPN Collector - Out of
Mobile Signal output will automatically activate. That way, the output can be used to notify the
lift's control panel that the emergency equipment is inoperative.
For more information, refer to the MMk-736 - M2M Communication Manual.

5. OPERATION
5.1. Incoming calls
The MMk-736 is capable of receiving two types of calls: voice calls and data calls. The
behaviour of the MMk-736 depends on the kind of call received.
5.1.1. Incoming voice calls
When the MMk-736 receives a voice call by means of the GSM line, it relays this call
through the simulated analogue telephone line output.
When the equipment connected to this output picks up, the MMk-736 answers the
incoming GSM call and establishes bidirectional communication.
Furthermore, DTMF tones can be sent to programme the emergency phones. These are
transmitted transparently through the GSM line's audio channel
2
.
5.1.2. Incoming data calls
This kind of call allows programming of the equipment WITHOUT transmission errors.
If the call received is a data call, the MMk-736 will answer it straight away, allowing access
to the internal parameters of the equipment.
Simultaneously, the MMk-736 relays this incoming call through the simulated analogue
telephone line output.
When the equipment connected to this output picks up, the call origin can transmit
characters associated to the set of DTMF tones (0..9, *, #, A, B, C, D), which the MMk-736
converts into audible DTMF tones in the simulated analogue telephone line output.
Similarly, if the equipment connected to the MMk-736 emits DTMF tones, these are
detected by the MMk-736 and retransmitted as characters along the data channel.
This type of call does not allow for the transmission of audio, and so they are only suitable
for programming emergency equipment, test calls, etc.
5.2. Outgoing calls
When a piece of telephone equipment connected to the MMk-736 dials a valid phone number,
the MMk-736 will make a call on the GSM line to that number.
Depending on the number dialled, the MMk-736 will apply a series of rules which allow this
number to be transferred to another one, and to make voice or data (CSD) calls, depending on
the case.
These rules are defined through the joining together of programmed settings in the MMk-736
(see section 6).
To be able to make data calls (CSD), the recipient equipment must be a set capable or
responding to this kind of call.
2
Due to the characteristics of the GSM network, it is not possible to ensure error-free transmission of DTMF tones through the voice
channel, and in some cases, depending on the level of network congestion, the error rate may be sufficiently high to impede effective
data transmission.

Installation Manual 13 of 16
5.3. Control of excessive number of calls
The MMk-736 can be programmed to detect an excessive number of outgoing calls and notify
this event with a text message.
This behaviour is defined using two parameters:
- Number of calls relayed: it indicates the maximum number of calls which may be made in
a time interval, as from which the MMk-736 will send a notification of an excessive number
of calls.
Once this limit is surpassed, the MMk-736 will send an SMS alert each time that a call is
made from the equipment.
- Interval for calls relayed counter: it indicates de duration of the time interval (in minutes)
during which the number of calls established by the “Number of calls relayed”parameter
cannot be surpassed.
6. ADVANCED FEATURES
The default configuration of the MMk-736 allows for its basic functioning as a telephone line
simulator.
However, the GSM gateway MMk-636 has a set of parameters which allow for advanced
features that give the equipment added value to be activated.
There are two types of advanced features:
Call diversion table
Activation of notifications
The equipment is programmed by means of SMS text messages. The content of these
messages is composed of a header and a list of pairs <parameter id>:<value>, as indicated below:
PROGGSM <confirmation> <password> <param1_id>:<param1_value> <paramn_id>:<paramn_value>
<confirmation>: The possible values are “s”or “n”. They tell the MMk-736 whether it
should send an SMS confirming that the programming was carried out correctly or
not. This confirmation SMS will be sent to the same phone the programming SMS
was sent from.
<password>: Access password of 4 digits for the MMk-736. The default value is
“0000”.
<paramn_id>: Number which identifies the parameter we wish to modify. In the
following list, the possible parameters and their corresponding identifiers are shown:

54: Number of calls relayed
55: Interval for calls relayed counter
<paramn_value>: Desired value to be assigned to the parameter.
Below it is shown how to programme the call diversion table and the different types of
notifications.
6.1. Programming the call diversion table
The MMk-736 can be instructed to divert a call dialled by the tele-alarm, to a different number,
according to the number dialled.
It is even possible to activate an unconditional diversion so that, independently of the number
dialled, all calls are made to the desired phone number.
Further, through the call diversion table, whether the call should be made in voice mode or
data mode (CSD) can be defined, and in this way the periodic test calls can be configured in
data mode and there will be no transmission errors.
It is possible to activate up to 4 diversions in which a voice call is made, and up to 4 diversions
in which the call will be made in data mode (CSD).
The MMk-736 will check whether the number dialled by the tele-alarm coincides with one of the
“origin phones”programmed, and if so, it will make the call to the corresponding “destination
phone”.
If the number dialled does not coincide with any of the “origin phones”, no diversion will be
made and the call will be made to the number dialled (see Figure 4.1).

6.2. Programming the activation of notifications
It is possible to configure the MMk-736 to send a notification by SMS when one of the following
events takes place:
A voice call has been made
An excessive number of calls has been made
An incident in the external power supply of the equipment has taken place
Insufficient battery charge has been detected
To tell the equipment to send these kinds of notifications, we must programme the number to
which they will be sent, and activate those notifications we wish to receive.
