1. Introduction

1.1. Purpose

• When connected to a PBX, the

MUSITEL®

- GSM Gateway allows its
users to make direct calls via the GSM network. It can work with a
telephone set, coin-operated automatic machines, etc.

• The voice mode, i.e. an outgoing or incoming call, is the basic function of
the Musitel GSM Gateway.
The Musitel is equipped with all functions necessary for this purpose and
offers ease of use in this mode.

• Moreover, the Musitel Gateway provides (in connection with a PC) data
mode and SMS receive/send mode too. With SMS messages, universal
inputs and outputs can be used also.
These additional functions increase the utility value of the product.

• You need no additional equipment (mains adapter, external GSM
telephone) to run the Musitel GSM gateway. The installation is so easy
that even a non-professional can install it.
All programmable parameters are set at optimum values by default.
Once you have connected the telephone line, antenna, power supply and
your SIM card, you can start making calls without hesitation.

1.2. How to Save GSM Call Costs

• By connecting a Musitel GSM Gateway to y our PBX you can make direct
calls into a mobile network.

This saves PSTN – GSM connection costs.

Mobile telephone calls
made by your colleagues from outside to your headquarters will be
cheaper too.

• With the GSM Gateway you can use

the most convenient tariff rate of

your GSM

operator, because calls of all y our G S M Gateway users will

be billed together.

• If you use

an answering and recording machine

– a GSM service, you
may pay for retrieving messages. If you connect an answering machine
of your own to the GSM Gateway,

you pay nothing for the retrieval

.

• With the Musitel GSM Gateway you can eliminate selected numbers.

You won’t pay for a call that is disabled.

• You can also get a listing of the time and length of selected calls to

find

easily why your bill is higher than it should be.

MUSITEL 52T, 53T & 61E page 6

1.3. Other Advantages and Applications

• You can establish a

telephone connection even where there are no

fixed telephone lines available

(exhibitions, fairs, conferences,

chalets...).

• You are not exposed to the high-frequency electromagnetic field as with
a mobile telephone.

• You can also attach a coin-telephone to the Musitel, as it is able to send
tariff pulses.
You can assess the price for call connections yourself (with profit).

MUSITEL 52T, 53T & 61E page 7

2. Basic Installation Instructions

This chapter describes the basic connection of the Musitel - GSM Gateway
that can be made in a few minutes.
All you have to do is to connect an antenna, the power supply cable and
telephone line, insert your SIM card and the GSM Gateway is ready to work.

2.1. Proper Location

• The

Musitel

®

- GSM Gateway is a transmitter in principle.
You must comply with the local regulations and laws in your country
pertinent to usage of mobile phones and transmitters!

• The Musitel - G S M Gateway is designed for vertical mounting.
For the required working position see Fig.1.

• The Musitel may be operat ed in a position other than vertical (on a desk,
e.g.) for a short time only – for quick maintenance testing, for example.

• For the acceptable range of operat ing temperature and humidity refer to
the “Technical Parameters”.

• The Musitel 52T, 53T and 61E may not be operated at places exposed
to direct solar or heat radiation.

• Exceeding the acceptable operating
temperature does not have an
immediate impact on the Musitel
function, but may result in
accelerated ageing (of batteries
in particular!) and lower reliability.

• The Musitel is designed for
indoor use. It must not be exposed to
rain, water, condensed moisture,
fog, etc.

• The Musitel must not be exposed to
corrosive gas, fumes of acids or
solvents, etc., or corrosive
liquids, during cover cleaning,
for example.

• The Musitel is not intended for use
in high vibration locations such as
means of transport, machine rooms, etc.

• The Musitel should be located
with respect to the GSM signal quality.

• A free space should be left over and
under the Musitel - GSM Gateway for
cables and flowing air that removes
heat produced during the operation.

2.2. Telephone Line Connection

2.2.1. MUSITEL 52T and 53T - Connection to PBX
models for external line of PBX

Connect the

Musitel 5xT

to a free external (C.O.) line of your PBX (the
Musitel 53T models for external (C.O.) and Musitel 61E for local line
(extension) are not interchangeable!).
With a CO line, define a different access number for this line than for the
remaining CO lines during the PBX programming.
Musitel 53T and 61E are equipped with the Least Cost Routing (LCR)
software, which allows you to use the same access number for all CO lines.

Fig. 2.:

Connection to PBX
C.O. line including callmaking
example

Access to Musitel 5xT, connected
this way (to external line of PBX)
must be provided by a prefix,
different to the prefix for C.O.
line access.
Another solution is a LCR
(Least Cost Router) inside the
PBX - software that is able to choose

MUSITEL 5xT

right direction for every call automatically.

2.2.2. Musitel 52Tand 53T - Connection to Telephone Set

(Answering

Machine, Coin- Operated Automatic Machine)

- models for external line of

PBX

You can connect any telephone set or some other terminal equipment to the
Musitel 52T and 53T; see Fig. 3.

Note:

If you connect a coin-operated phone, be sure to program the
transmission of tariff pulses and pseudo tariff met ering properly as well as to
bar calls with unpredictable tariff rates!

2.2.3. MUSITEL 61E- Connection to PBX
models for local line of PBX (extension)

Connect the Musitel 61E to an unused local line of your PBX (extension).
Attention! The GSM Gateway models for external (C.O.) and local line
(extension) are not interchangeable!

Attention!

It is highly recommended to set your PBX to disable outgoing
calls from this extension to C.O. lines, and to disable access to this
extension from C.O. lines.
This way you avoid an abuse of GSM gateway from "outside" (making
expensive long-distance calls on your bill).

MUSITEL 61E

Fig. 4.: Connection to PBX local line (extension) including call-making example

MUSITEL 52T, 53T & 61E page 10

2.3. External Antenna Connection

Connect an antenna or an external antenna cable into the FME connector.
The antenna location should have a good GSM signal. The antenna should
be in the vertical position. For antenna and cable parameters refer to the
“

Technical Parameters

”.

Tighten an antenna connector gently by hand;

do not use any tools!

2.4. SIM Card Set-up and Installation

2.4.1. Operator / SIM Card Selection

To perform this GSM Gateway function you need a SIM card of a GSM
network operator, using the 900 MHz or 1800 MHz band (depending on
GSM gateway model). The

MUSITEL

-GSM Gateway works with 3V SIM
cards. All SIM cards except for the oldest ones meet this condition. If you
are not sure, ask your GSM operator about voltage of your old SIM card.
If your SIM card is new or you are going to buy a new one, you need not
worry – your SIM card will be O.K.

2.4.2. PIN Entering Blocking (Optionally)

The Musitel provides automatic PIN entering by default. You can disable
PIN entering on your SIM card (using a mobile telephone into which you
insert your SIM card for this purpose).
If you do disable, you need not worry as to whether there is a PIN code
stored in your Musitel memory. If you enable PIN entering, your GSM
Gateway will require a PIN code after the first power-on and if you enter the
PIN correctly, the GSM Gateway will store it in its memory and enter
automatically in the future.

2.4.3. GSM Network Service Setting (Answering Machine, Call
Forwarding)

Before the SIM card installation decide whether you will use the

incoming

call forwarding

service provided by GSM networks (call forwarding in the
event of busy line, absence, unavailability...). However, it is more
convenient to disable all call forwarding modes (the GSM operator’s
answering machine, e.g.) and use an answering and recording machine of
your own. If you have more Musitel’s with your PBX, you can forward calls
when one GSM Gateway is busy, etc.

MUSITEL 52T, 53T & 61E page 11

2.4.4. Roaming Parameters Setting (Calling via Foreign GSM Networks)

The GSM Gateway disables roaming by default. I t is usually convenient
because most people do not travel with the Musitel and there is a risk with
roaming in foreign countries that, due to a failure in the local GSM network,
you might get registered in another network and pay much more for your
calls. To enable roaming and set network preferences, complete the list of
GSM networks to be preferred using your mobile telephone and then enable
roaming while programming the GSM Gateway.
The registration of the GSM Gateway in a foreign GSM network is signalled
by a special dial tone (refer to the list of tones) and you have to dial
numbers including international prefixes that can be easily barred (refer to

Programming, Call Sorting Table

).

2.4.5. SIM Card Insertion in GSM Gateway

Some models have a cover without hole for SIM exchange. In this case,
release the two screws and remove the upper cover face (see Fig. 6).
To install the SIM card press the yellow button on the SIM holder using a
suitable tool (e.g. scissor) to make the drawer slide out. Remove the drawer,
insert the SIM card in it, slide the drawer back and click into position.
Then replace the cover face and tighten the screws, if removed.
This protects the GSM Gateway circuits against dust and damage!

2.5. Power Supply Connection

2.5.1. For all GSM gateways models



Make sure that the voltage in your mains corresponds with the data on
the product label.



Make sure that the antenna has been connected. If you connect a
power supply to the equipment without the antenna, you might
cause damage to the GSM module transmitter.



Connect your power cord. After a while, the green indicator “AC Supply
O.K.” should go on.

2.6. Back-Up Battery Connection

This paragraph applies to models Musitel 53T and Musitel 61E.
For these models, a back-up battery with cover can be ordered - ordering
No. 910121090 (E).
This is a maintenance-free lead battery pack 12V / 1,2Ah with metallic
cover, whose design matches the GSM G ateway. This cover includes the
accessories for wall mounting.

MUSITEL 52T, 53T & 61E page 12

Battery installation

While placing the battery pack, avoid exposing it to high temperature if not
necessary and mount it to the wall, if possible. Mounting method, holder etc.
is the same, as for GSM gateway.
Plug a cable into a fitting connector on GSM gateway. Check a fuse in
holder and insert it, if the holder is empty. Switch on.

Notes:



Circuits in Musitel are designed to handle 12V / 1,2Ah maintenance-fr ee
lead battery.
Also a different lead battery with a nominal voltage 12V and a capacity of
1 to 2Ah or a set of 10 NiCd or NiMH cells of the capacity from 600 to
1,600mAh can be used too. Of course, a manufacturer cannot guarantee
a proper charging, if the battery parameters are too different.
Especially, a battery of a higher capacity may not reach an end-of-charge
voltage. It may cause a permanent charging, and it m ay damage the
battery! Such battery must be charged externally.
In this case, the charging function has to be disabled by software – see
chapter 7.1, parameter 170. An external 12V power can be applied too.



The accumulator is charged and checked automatically, and the GSM
Gateway indicates the charging and emergency statuses

(disconnected,

short-circuit, or fully discharged battery)

and stores these events in the
service buffer. If lamp "charge" is dark (strict ly speaking, it flashes
shortly with a long period, done by conservation charging), the
accumulator is fully charged.
End of charging, discharging and all failures, such as disconnected
accumulator or short circuit, are stored in service buffer .



See chapter 5.5 for details, as well as for standard battery replacement .

MUSITEL 52T, 53T & 61E page 13

2.7. Functional verification

Recommendation: check GSM gateway functionality prior to connecting it to
your PBX and programming.

2.7.1. MUSITEL 53T - for GSM gateways for external (C.O.) line of PBX

If you have a GSM gateway model MUSITEL 53T for

external (C.O.)

lines

on a PBX, follow these instructions:

1. Connect GSM gateway to previously checked telephone set.
Verify that t his telephone is switched to DTMF and its ringer is ON.
If is better to check a SIM card too, using a mobile phone. It is not
necessary to fix GSM gateway to a wall for testing – it can lie on flat
surface as well.
Excepting this, follow chapters 2.2 to 2.5 to connect all needed.

2. If the inserted SIM card requires a PIN, the red lamp “Enter PIN” will light
up. In this case, pick up the handset of connected a phone.
You will hear a PIN tone .
Enter PIN as described in chapter 3.9.2 and hang up, the red “Enter PIN”
lamp will go out.

3. The GSM gateway will register itself into the GSM network. First, the red
“No GSM network” lamp must go out. After a moment, the green “GSM
ready” lamp will light up.

4. Pick up the phone; you will hear the dialling tone and the green “Line
ready” lamp will start blinking. If it doesn’t, the phone or its connection is
bad.

5. Now check for signal quality. Ent er programming mode according to
chapter 6.3.2, skipping step No. 1 (this applies only in the case of
connection to a PBX). Indication of GSM signal quality will be turned on
automatically.
As more lamps are lit, signal quality is better .
If at least one green lamp is lit up, signal quality is excellent.
Try to find a good place for the antenna.
Keep the antenna vertical and move it slowly – signal quality information
is updated every three seconds.
Remember that a movement as small as 10 cm may have a
considerable effect on signal quality, as well as a position close to your
body.
The best way is to step aside after each relocating of antenna.
Hang up after positioning the antenna; do not program anything!

6. Make an outgoing call. Call your colleagues mobile e.g. and verify that
you hear each other well. In the case of a completely new pre-paid SIM
card, one outgoing call is necessary for SIM card activation.
Until it is activated an incoming call cannot be received! Make an
incoming call now.

MUSITEL 52T, 53T & 61E page 14

Call the Musitel 53T; the phone should ring.

7. The Musitel 53T is now checked. You can now connect it to a vacant
C.O. line in the PBX.
After connection is completed, check both incoming and outgoing calls
again.
This may, of course, necessitate some programming or settings changes
of the PBX.
If everything is O.K., you can go to programming, if it is required - see
chapter 6.

MUSITEL 52T, 53T & 61E page 15

2.7.2. MUSITEL 61E - for GSM gateways for local line (extension)
of PBX

If you have a GSM gateway model for a

local line (extension)

in the PBX,

follow these instructions:

1. Use an unused, previously checked local line of PBX.
Special lines, such as lines for so called "key phones", or ISDN lines
cannot be used! It is recommended that the PBX will give a busy or
permanent tone after call finishing (after hooking up on one side,
the other side is advised by this tone).

2. Use a previously checked telephone handset, switched to DTMF and
connected to another extension of the PBX. It is best to use a cordless
phone; this allows you to closely observe the lamps on the Musitel 61E.

3. Disconnect the phone, which was previously used to check the unused
line. Using the same cable connect the Musitel 61E.
It is recommended that you check the SIM card too, using a mobile
phone. Again it is not necessary to fix the Musitel to the wall for testing
– it may be placed on a flat surface if necessary.
After this, follow chapters 2.2 to 2.5 to make all required connections.

4. If inserted SIM card requires a PIN, red “Enter PIN” lamp will light up.
In this case, pick up the phone connected to another extension (e.g.
cordless phone) and call GSM gateway extension. You will hear a
PIN tone . Enter pin as described in chapter 3.9.2 and hang up. Red
“Enter PIN” lamp will go out.

5. The Musitel 61E will register itself into the GSM network.
First, red “No GSM network” lamp must go out (if present).
After few seconds the green “GSM ready” lamp will light up.

6. Pick up the phone connected to another extension (e.g. cordless phone)
and call Musitel 61E extension; you will hear dialling tone and green
lamp “Line ready” will start blinking. If not, and you hear ringing only, the
phone or its connection is bad or you called an invalid extension number.

7. Now check signal quality. Ent er programming mode according to chapter

6.3.2. Indication of GSM signal quality will be turned on automatically.
As more lamps light up, signal quality is better .
If at least one green lamp is lit, signal quality is excellent.
Try to find a good place for antenna. Keep the ant enna vertical and
move it slowly – signal quality information is updated every three
seconds.
Remember that a movement as small as 10 cm may have a
considerable effect to signal quality, as well as a position close to your
body. The best way is to step aside after each relocating of the
antenna. Next, if PBX doesn't support DTMF dialling, program
parameter 114; switchboard operator number, i.e. extension to be called
in case of incoming call and set parameter 311 - type of dialling, to pulse
dialling. Programming can be done by phone - see chapter 6.3 , or by

MUSITEL 52T, 53T & 61E page 16

PC. It is not possible to check an incoming call without this setting!

8. Hang up after placing antenna; do not program anything!

9. Make an outgoing call. Call your colleagues mobile e.g. through the
Musitel 61E and ensure that you hear well each other.
In the case of a completely new pre-paid SIM card, one outgoing call is
necessary for SIM card activation.
Until the SIM is activated, an incoming call cannot be made! Check an
incoming call now. Call the GSM gateway.
If PBX doesn't support DTMF dialling, line selected by parameter 114 will
be ringing.
Otherwise, you will hear the dialling tone of your PBX.
Dial the number of an extension; the phone will ring.

10. The Musitel 61E is now checked.
If necessary you can go to programming now - see chapter 6.

MUSITEL 52T, 53T & 61E page 17

2.8. LED Indicators

2.8.1. Table – Basic LED Functions.

Note:

Three LED's destined for battery status indication (Battery charge,

Battery supply, Battery low) are unused in models without battery backup.

MUSITEL 52T, 53T & 61E page 18

2.8.2. Signal Intensity Indication

On models MUSITEL 53T and MUSITEL 61E the bottom group of nine
LEDs is used for indicating the GSM signal level.
Using the “GSM Signal Level Indication” (refer to

Programming, Basic

Parameters

) you enable the indicating mode where the Musitel displays the
signal intensity for 2 seconds every 10 seconds.
In the meantime, the

LED's

indicate all statuses normally.
When the GSM Gateway is in the programming mode, the LEDs indicate the
signal intensity continuously and the information is updated every three
seconds. This mode is suitable for searching for the ideal antenna position
during installation.

2.8.3. LED indicators

3. User Manual – Description of Basic ( Voice) Function

Users mostly use their PBXs and MUSITEL intuitively, without reading any
instructions, or follow very simple instructions provided by an authorized
person. The following functional description is therefore intended for
technicians, who follow the instructions (depending on the PBX set-up) and
solve any operational problems.

3.1. Outgoing Calls - MUSITEL 52T and 53T
GSM Gateway on PBX’s CO line

3.1.1. Picking Up the Line

The PBX picks up a line the moment a subscriber picks up his or her
handset and dials a number that is interpreted by the PBX as the
“MUSITEL Access code“.
This code depends on the PBX type and set-up.
Some PBXs accept the GSM prefix as this code.
Then, the user need have no worry that the call is made via the Musitel.

Note

: If the Musitel 5xT is busy, the PBX can either give the caller the
busy tone or choose another connection (PSTN, or there may be more
GSM Gateways with one PBX).

3.1.2. Musitel 52T and 53T - GSM Gateway Ready Signalling

The Musitel 5xT registers the off-hook (current inflow) immediately and
then, if everything is O.K., starts sending its usual dialling tone .
Now the subscriber can dial the number.

Note:

If there is no GSM signal, no SIM card has been inserted, no PIN
code has been entered, or if there is another problem, the PBX transmits
a special tone (see below – “Telephone Line Tones“).

3.1.3. Dialling Receive

The Musitel 5xT is ready to receive pulse or tone dialling (according to
the set-up). As soon as the subscriber starts dialling a number, the
Musitel mutes the dialling tone (as with public telephone exchanges).
The user must dial digits in no more than 6 second intervals; otherwise
the number is regarded as complete and sent to the GSM network (this
timeout is programmable).

Note:

Some PBXs analyse the whole number first and then transm it the
dialling into the CO line (Musitel). Here, the signalling t y pe and the
timeout depend on the PBX set-up!

3.1.4. Dialling End Recognition

The Musitel 5xT itself can recognize the end of some numbers according
to their length.

MUSITEL 52T, 53T & 61E page 20

Moreover, you can set your Musitel in such a way that the Musitel 5xT
accepts the ‘L‘ or ‘#‘ (for tone dialling only) symbols as the end of
dialling.
Otherwise, it waits 6 seconds after the subscriber stops dialling (the
timeout is programmable).
Then, the subscriber can hear a short tone signalling the dialling end and
the Musitel transmits the received number into the GSM network.
If the caller goes on dialling, the Musitel GSM Gateway will not accept
the extra digits!

3.1.5. Connection Establishing

In this moment, Musitel is making a connection, and it takes typically 8
seconds.
During this time, the subscriber hears a special "call progress" tone
(differs by GSM gateway model and version of software). Next, the
subscriber usually hears the ringing tone or another signal transmitted by
the GSM network. The connection, however, is not established and paid
for until the called party answers the phone.
The GSM network signals this moment and the Musitel 5xT can pass the
information to the PBX. If this type of signalling is used (exceptionally),
the calling party can hear a click in the earphone.

3.1.6. Call

During outgoing calls, the Musitel 5xT is computing the cost (pseudo
tariff metering) and it can send tariff pulses. A call may be terminated
forcibly if the GSM signal gets lost, for example, or in similar situations.

3.1.7. Connection Termination (End)

If the caller is the first to hang up, the Musitel registers the on-hook
immediately (the current flow stops) and terminates the connection.
If the called party is the first to hang up, the M usitel 52T and 53T gets

the information from the GSM network and terminates the connection.

The Musitel can pass the information to the PBX.
The calling party gets the busy tone (or another type depending on t he
set-up).

Note: With some calls, the called party‘s on-hook information is
considerably delayed by GSM network (30s, e.g.). The subscriber
usually registers the on-hook earlier, hangs up, and the Musitel 5xT
terminates the connection immediately.

3.1.8. Subscriber’s Disconnection (Power Down)

If a subscriber blocks the Musitel by seizing the line without dialling a
number, or fails to hang up after the call, he or she will get the busy tone
first and then is disconnected (Power Down status).

MUSITEL 52T, 53T & 61E page 21

3.2. Outgoing Call - MUSITEL 61E
GSM Gateway on PBX’s Subscriber Line

3.2.1. Musitel 61E Ringing

The subscriber picks up the line and dials the extension number of
Musitel.
The PBX starts ringing this extension; the Musitel 61E registers this and
picks up the line after a programmed time.

Note

: If the Musitel 61E is busy, the PBX can either give the caller the
busy tone or start ringing another extension (there may be more Musitel ­GSM Gateways than one with one PBX).

3.2.2. Musitel 61E Ready Signalling

After picking up the line, the Musitel 61E starts sending the usual dialling
tone (if everything is O.K.). Then the subscriber can dial the number.

Note:

If there is no signal, no SIM card has been inserted, no PIN code
has been entered, or there is another problem, the Musitel transmits a
special tone (see below – “Telephone Line Tones“).

3.2.3. Dialling Receive

The Musitel 61E is ready to receive tone dialling. As soon as the
subscriber starts dialling a number, the Musitel stops sending the dialling
tone (as with public telephone exchanges).
The subscriber must dial digits in no more than 6 second intervals;
otherwise the number is regarded as complete and sent to the GSM
network (the timeout is programmable).

3.2.4. Dialling End Recognition

The Musitel 61E itself can recognize the end of some numbers according
to their length.
Also, you can set your Musitel in such a way that the Musitel accepts the
‘L‘ or ‘#‘ symbols as the end of dialling.
Otherwise, it waits for 6 seconds after the subscriber stops dialling (the
timeout is programmable).
Then, the subscriber can hear a short tone. signalling the dialling end
and the GSM Gateway transmits t he dialling into the GSM network.
If the caller goes on dialling after this signal, the Musitel 61E will not
accept the excessive digits!

3.2.5. Connection Establishing

In this moment, Musitel 61E is making a connection, and it takes typically
8 seconds.
During this time, the subscriber hears a special "call progress" tone
(differs by GSM gateway model and version of software).
Next, the subscriber usually hears the ringing tone or another signal

MUSITEL 52T, 53T & 61E page 22

transmitted by the GSM network. The connection, however, is not
established and paid for until the called party answers the phone.

3.2.6. Call

During outgoing calls, the Musitel 61E only computes the cost (pseudo­tariff metering) and detects the permanent tone, busy tone or another
tone (e.g. ringing) to terminate the call.
A call may be terminated forcibly if the GSM signal gets lost, for example,
or in similar situations.

3.2.7. Common Connection End

If the caller is the first to hang up, the Musitel 61E registers the on-hook
immediately (usually permanent or busy tone from the PBX) and
terminates the connection.
If the called party is the first to hang up, the Musitel get s the information
from the GSM network and terminates the connection.
The calling party then gets the permanent or busy tone (depending on
the set-up).

Note:

With some calls, the called party‘s on-hook information is
considerably delayed by GSM network (30s, e.g.).
The subscriber usually registers the on-hook earlier, hangs up, and the
Musitel terminates the connection immediately.

3.2.8. Other Connection End Cases

If a subscriber blocks the Musitel 61E unnecessarily by calling it and not
dialling a number, or fails to hang up after a call, the Musitel hangs up
after a programmable timeout.
The Musitel 61E also hangs up when it has received the busy tone from
the GSM network (when the calling party is busy or refuses the call).

MUSITEL 52T, 53T & 61E page 23

3.3. Incoming Call - MUSITEL 52T and 53T
GSM Gateway on PBX’s CO Line

3.3.1. Musitel 53T Ringing, Extension Dialling, Extension Ringing
and Connection Establishing

When the Musitel 5xT receives a command from the GSM network and,
if available, the CLIP information, it starts ringing (i.e. generating the
ringing voltage – whose timing is programmable) into the PBX.
The PBX registers the ringing and then, one of the following situations
may occur:

3.3.1.1 PBX without DISA = Selected Extension Ringing

In this case, the selected extension (or several extensions at the same
time or sequentially according to the PBX set-up) starts ringing and the
calling subscriber will not pay for the call until the ringing extension
answers.

3.3.1.2 PBX with DISA, Intelligent Routing Off

In this case, the PBX answers and starts reproducing the so-called DISA
message.
The Musitel 5xT establishes connection immediately in order that the
caller can hear the message and dial the required extension.

3.3.1.3 PBX with DISA, Intelligent Routing On, and CLIP Present and

Known

In this case, the PBX also answers and starts reproducing the DISA
message.
The Musitel 5xT, however, has found the caller’s number in its Intelligent
Incoming Call Routing Table and thus knows the extension to be called.
Therefore, the Musitel 5xT does not establish connection immediately,
but serves the DISA function (waits and dials the extension number).
Then, it establishes the connection and the calling subscriber can hear
the ringing tone and the called subscriber.

3.3.1.4 PBX with DISA, Intelligent Routing On, but CLIP Absent or
Unknown

In this case, the PBX also answers and starts reproducing the DISA
message.
The Musitel 5xT, however, has not found the caller’s number in its
Intelligent Incoming Call Routing Table (or has not received the CLIP).
Then it can (according to its set-up) either work as described in 3.3.1.2,
or as described in 3.3.1.3, plus dial the operator’s number.

MUSITEL 52T, 53T & 61E page 24

3.3.2. Call

With incoming calls, the Musitel 5xT waits until the call is terminated,
which situation is the same as with an outgoing call.
A call may be terminated forcibly if the GSM signal gets lost, for example,
or in similar situations.

3.3.3. Connection Termination (End)

If the called subscriber (extension) is the first to hang up, the Musitel 5xT
registers the on-hook immediately (the current flow stops) and terminates
the connection.
If the calling party (PSTN) is the first to hang up, the Musitel 5xT gets the
information from the GSM network and terminates the connection.
The Musitel can pass the information on the PBX.
The calling party then gets the busy tone (or another tone depending on
the set-up).

Note:

With some calls, the called party‘s on-hook information is
considerably delayed by GSM network (30s, e.g.).
The subscriber usually registers the on-hook earlier, hangs up, and the
Musitel terminates the connection immediately.

3.3.4. Subscriber Disconnection (Power Down)

If a subscriber blocks the Musitel 5xT unnecessarily by not hanging up
after the call, he or she will get the busy tone first and then is
disconnected (Power Down status).

MUSITEL 52T, 53T & 61E page 25

3.4. Incoming Call - MUSITEL 61E
GSM Gateway on PBX’s Subscriber Line

As this procedure is most sophisticated and it may be difficult to
understand it, it is described by two forms: flowchart and text.
Please, choose a form, which you are more familiar with.

MUSITEL 52T, 53T & 61E page 26

3.4.1. Musitel 61E Ringing

When the Musitel 61E receives a command from the GSM network and
the CLIP information, if available, it picks up a subscriber line of the PBX.
Then, one of the following two situations may occur:

3.4.1.1 Extension Dialling - Intelligent Routing On, and
CLIP Present and Known

The Musitel 61E has found the caller’s number in its Intelligent Incoming
Call Routing Table and knows the extension to be called.
Hence, it dials the extension number.

Exception:

If 0 (

zero

) is found in Intelligent Incoming Call Routing Table
instead of extension number, Musitel 61E skips dialling, and calling part y
hears a dialling tone from PBX and dials number of required extension
by DTMF.

Attention!

In this case, PBX must support DTMF. If pulse dialling is

selected, and the switchboard operator’s number is present (parameter

114), M usitel dials this number.
If the switchboard operator’s number is empty, Musitel 61E refuses this
incoming call.

3.4.1.2 Extension Dialling - Intelligent Routing Off,
CLIP Absent or Unknown

The Musitel 61E has not found the caller’s number in its Intelligent
Incoming Call Routing Table (or has not received the CLIP, or Intelligent
Routing is off).
If a parameter 310, "enable dialling for incoming call" is enabled, GSM
gateway only picks up a line, such that a calling party hears a dialling
tone of PBX and dials an extension number by himself.
Otherwise, GSM gateway dials the pre-set number, the operator’s
number, e.g.

Attention!

If pulse dialling is selected, Musitel 61E ignores a parameter
353 and dials an operator's number.
If operator's number is not programmed, an incoming call is rejected.

3.4.2. Extension Ringing, Connection Establishing

If calling party dials an extension, the Musitel GSM Gateway establishes
connection immediately, without waiting for any "connect" handshaking
from PBX (if used or not).
If Musitel 61E dials an extension (to switchboard operator, or by I2CR
table), then it establishes connection just after dialling extension number
(above), or wait for "connect" handshaking from PBX (if used; in this
case PBX

must

send it, otherwise call cannot be connected!).
The calling party can hear the ringing tone either from PBX, or from GSM
network - it depends on this setting.

MUSITEL 52T, 53T & 61E page 27

3.4.3. Call

With incoming calls, the Musitel 61E only detects the permanent tone,
busy tone or another tone (e.g. ringing), i.e. waits until t he call is
terminated, which situation is the same as with an outgoing call.
A call may be terminated forcibly if the GSM signal gets lost, for example,
or in similar situations.

3.4.4. Common Connection Termination (End)

If the called subscriber (extension) is the first to hang up, the Musitel 61E
registers the on-hook immediately (usually the permanent or busy tone
from the PBX) and hangs up.
If the calling party (PSTN) is the first to hang up, the Musitel 61E gets the
information from the GSM network and hangs up.
The calling party then gets the busy tone (or another tone depending on
the set-up).

Note: With some calls, the called party‘s on-hook information is
considerably delayed by GSM network (30s, e.g.).
The subscriber usually registers the on-hook earlier, hangs up, and the
Musitel 61E terminates the connection immediately.

3.4.5. Other Connection End Cases

If the called subscriber blocks the Musitel 61E unnecessarily by not
hanging up after the call, the Musitel hangs up after a programmable
timeout.
The Musitel 61E also hangs up when it has received the busy tone from
the GSM network (when the calling party is busy or refuses the call).

3.5. More local calls during one GSM connection
with Musitel 61E

This possibility relates only to Musitel 61E for

local line of PBX

(extension).
This is contingent also on PBX's behaviour after end of local call: we
assume that an extension, which remain off-hook, after a second one
hooks up, hears a dialling tone and can dial another number, without
hanging up line and picking up again.
In this case, if local user (any extension of PBX), talking with remote user
(mobile, connected with Musitel 61E by GSM network) hangs up, remote
user hears a dialling tone and can dial another number.
This possibility applies to both incoming and outgoing calls. It may be
advantageous, e.g. if one employee needs to talk from "outside" with
more colleagues (in sequence), and a call is charged by flat price
(regardless of its duration).

MUSITEL 52T, 53T & 61E page 28

But the same possibility can be abused - e.g. for long, expensive long­distance calls.
Therefore, it is recommended to set your PBX to disable outgoing calls
from this extension to C.O. lines.

3.6. Automatic dialling ("baby call")

Outgoing calls are described in chapters 3.1 and 3.2 on the assumption
that automatic dialling is off (default).
If parameter "Number for automatic dialling" is filled, this function is
automatically switched on and Musitel operates as follows:

Musitel 52T and 53T - Model for external line :

As soon as line is picked up, Musitel 5xT awaits dialling for limited time,
defined by parameter "time for automatic dialling".
If user starts dialling within this time, Musitel 53T operates normally, as
described in chapter 3.1.
Otherwise, if this time is out, Musitel 5xTgateway automatically makes a
call to programmed number.

Note: It is assumed, that Musitel 5xT GSM gateway is connected to
phone.
If Musitel 5xT is connected to PBX, applicability of automatic dialling
function depends on PBX's settings.

Musitel 61E - Model for local line :

Musitel 61E detects ringing from line and picks up.
Then awaits dialling, for a time defined by parameter " time for automatic
dialling".
If user starts dialling within this time, Musitel 61E operates normally, as
described in chapter 3.2.
Otherwise, if this time is out, Musitel 61E automatically makes a call to
programmed number.

MUSITEL 52T, 53T & 61E page 29

3.7. Intelligent Incoming Call Rout i ng - Musitel 52T, 53T and 61E

This function can be applied to incoming calls (if enabled).
If CLIP (number of calling subscriber) is found in Intelligent Incoming Call
Routing Table (see chapter 7.6.), Musitel will call a dedicated extension
according to this table.
If Musitel 52T or 53T is connected to external (C.O.) line of PBX, DISA
function must be used in PBX to serve it.
This function is operating automatically, as described in previous
chapters 3.3 and 3.4.

3.7.1. Intelligent Incoming Call Routing Control

From the viewpoint of the user, this function can work completely
automatically but moreover it is possible to complete the Intelligent
Incoming Call Routing Table during any call by special command:

Command for Intelligent Incoming Call Routing fill-up:

If the Musitel executes this command, it will send a confirmation signal as
well as sending an error signal in the following events:



Routing is disabled (error will be sent as soon as password is entered).



Whole table is “locked” – only programming by PC can modify it.



CLIP is unknown (error will be sent as soon as password is entered).



CLIP is already stored in locked part of table; this entry has a priority and
cannot be modified.

Notes:



If 0 (zero) is entered instead of extension number, Musitel enables calling
party to dial any number. This is a way, how to enable this possibility
only to selected persons. Another incoming calls are connected to pre­selected extensions or refused (dependent on a Musitel configuration).



Only unlocked part of table can be filled-up by this command.

MUSITEL 52T, 53T & 61E page 30

Once it is full, new ones will overwrite oldest entries. Size of available
unlocked part is from 0 to 99 entries, depending on size of locked part .
Only programming by PC can modify the siz e of locked part and its
content.



This command is ignored until a connection is established.



In the case of outgoing calls, the called subscriber number is usually
incomplete (without international prefix). In case of incoming call, CLIP
is complete and international prefix starts with “+”.
To make these numbers comparable, incomplete number is completed
automatically within writing to the table, using your international prefix –
parameter No. 6002, see chapter 7.6, this way:

3

If called number begins with “00” (or with different international prefix
defined by parameter 115), it is removed and only “+” character is
added to its beginning.

3

If called number begins with one “0” (or with different long distance
code defined by parameter 117), it is removed and “+” and your
country code is added to its beginning.

3

In other cases, “+” and your country code is added to its beginning.



While programming by PC, an incomplete CLIP can be entered – e.g.
bare international prefix. In this example, incoming calls from each
country will be routed to the person who is proficient in the appropriate
language etc.



While programming by PC, each CLIP must begin with country code.

3.8. Telephone Line Tones, Ringing Course - Summary

The MUSITEL - GSM GATEWAY transmits tones to the telephone line
that signal its operating status. The frequency is 425 Hz for all tones.

Common Dial tone:



Continue tone with break from 100msec.



The equipment is registered in the domestic GSM network.

This tone is transmitted if:



The SIM card has not been installed.



The GSM Gateway is not registered in the G S M network.



The equipment is registered in a foreign network, but roaming is

disabled.



The called number has too many digits (over 20).



The called subscriber is busy.



The called number is bared by call sorting table.



The connection has been terminated.



There is a communication error between the control processor

and the GSM module, and a servicing intervention is required.



This tone has the same parameters as the PSTN busy tone.



The parameters of this tone are programmable.

Dialling End Signalling:



The dialling reception is terminated, and the connection is being

established.



1 tone, 200 ms (programmable).

PIN Tone:





Transmitted upon power-on if the PIN code has to be entered

manually.

PUK Tone:



Your PUK code is required.



Transmitted upon repeated incorrect PIN code entering and the

subsequent SIM card blocking.

PIN/PUK OK:



This 2 s long tone signals that the PIN or PUK code was entered

correctly.

Ringing Course:

The ringing course (1 s ringing, 4 s pause) is the same as in the PSTN, but
can be reprogrammed any time.

MUSITEL 52T, 53T & 61E page 32

MUSITEL 52T, 53T & 61E page 33

3.9. PIN/PUK Code Entering

3.9.1. Three Way s o f PIN Code Entering

With a common mobile telephone, you have to enter your PIN code after
power-on in order to be protected against misappropriation (of your
powered-off telephone) and misuse. With the Musitel, this situation may
occur after power failure. The difference is that there is often no one to
know and enter the PIN code after power recovery .
There are three ways in which to solve this situation:

a) Enable the SIM card function without PIN code entering:

This is the simplest solution, but the SIM card can be easily misused
when stolen.

b) Set the automatic PIN code entering:

The PIN code is entered during programming or after power up of the
Musitel as mentioned below and stored in the memory.
The PIN code is then entered automatically after every power-on.

c) Set the manual PIN code entering:

This is the safest way, which requires manual entering of the PIN code
after every power on.
Therefore, it is useful for backed-up models only where such situations
are rare.

3.9.2. PIN, PUK Manual Entering

If the PIN
or PUK
tone is transmitted after picking up the line, enter the required code using
the DTMF and verify the dialling with the key.

If you enter the correct code, you will hear a 2 s long tone . If not, the
PIN/PUK tone will go on. An incorrect entering (incorrect PIN or PUK,
incorrect number of digits, unacceptable characters) makes the PIN or PUK
tone being transmitted repeatedly.
To delete an incorrect code, press ‘#’ or hang up (before entering ‘L’, of
course).

MUSITEL 52T, 53T & 61E page 34

Notes :

•

A four-digit PIN code is used in the example above. An eight-digit PIN
code is used exceptionally. The GSM Gateway supports this PIN too,
but has no information on how long the PIN should be. Theref ore, it
transmits the same PIN tone for this PIN code too.



The GSM Gateway does not support emergency calling without PIN
code!

3.9.3. Protection against Exhausting All PIN Entering Attempts by
Automatic PIN Entering

Every SIM card provides a limited number of PIN and PUK entering
attempts.
To avoid exhausting of all PIN-entering attempts, as a result of repeated
GSM Gateway power on/off after SI M card replacement, for example,

the automatic PIN entering is disabled temporarily

in case the SIM
card refuses the PIN stored in the GSM Gateway memory.
If the PIN is entered manually and is correct, it is stored and the
automatic entering is recovered.

3.10. Notes



Telephone Line Power Down (Musitel 52T and 53T - Model for
External Line of PBX Only)

Dialling , busy , PIN and PUK tones are transmitted into a line for 60s.
When this time elapses, the line is put in the Power Down status (no
power supply) until it is hung up.
In the programming mode, the line is put in the Power Down after 180s.



DISA

The DISA service relates to incoming calls only and those Musitel 53T
that are connected to the PBX’s external (CO) line.
The Musitel 5xT itself is not equipped with the DISA function because it
is useless – it is more convenient to use the PBX DISA.
For more details on the function refer to par. 3.3.1

- “GSM Gateway
Ringing, Extension Dialling, Extension Ringing and Connection
Establishing”.

If DISA is used, you are recommended to forward incoming calls at night,
during absence or busy line to the operator, mailbox or answering
machine, because any connection attempt is billed to the calling
subscriber.
Further, remember that the G SM operator usually limits the ringing time
