Introduction

INTRODUCTION

The MAGIC TH2 system allows the forwarding of telephone calls to analogue and digital Audio interfaces.

The connection to the telephone network can be established either via an analogue POTS interface or via ISDN.

To optimise the calling signal each caller line has implemented its own digital Echo Canceller, an AGC (Automatic Gain Control) as well as an Expander.

The configuration of the system can be made via the Windows application included in delivery or via the front keypad of the unit. Optionally, the MAGIC TH2 Keypad is available for separate operation without a PC.

Construction

1 CONSTRUCTION

The functions of the MAGIC TH2 are implemented in a single unit. The system is designed for mounting in a half 19" rack(1 U).

Optionally, a dual mounting kit is available (MAGIC TH2 DUAL 19“ Mount- ing Kit ID: 800202) for installing two MAGIC TH2 systems next to each other.

System Description

2 SYSTEM DESCRIPTION

The functional elements of the system are pictured in Fig. 2.

FIG. 2 FUNCTIONAL ELEMENTS OF THE MAGIC TH2 TELEPHONE HYBRID

2.1 Functionality

The MAGIC TH2 system incorporates an analogue POTS interface as well as an ISDN interface. The operating mode can be set with the help of a software. If the ISDN telephone interface is used, two independent telephone hybrids are available within one system (channel 1 and channel 2). If the analogue POTS telephone interface is selected, only one line can be used.

The complete signal processing is taken over by a digital signal processor. In this way the following functions are carried out:

– G.711 Audio encoding and decoding –two independent Echo Cancellers for each line –two independent AGCs (Automatic Gain Control) –two independent Expanders (to suppress spurious signals) – control of the complete system (Keypad, Display, Relay, TTL, RS232)

As ON AIR Audio interfaces (input/output) for the mixing u nit two independent analogue channels as well as a optional digital AES/EBU interface are available. If the AES/EBU interface is selected (optional AES/EBU software licence is necessary), both channels are multiplexe d to ge the r (right/left channel). The input as well as the output possesses a separate digital Sample Rate Converter (SRC). For connection with an external clock a clock input and a clock output are available.

Page 18

PAGE 18

System Description

A separate PRETALK interface provides the possibil ity for Pre Talk. In the analogue POTS operating mode a standard analogue telephone can be connected to the system. Via this telephone the connection to the subscriber can be established or a call can be accepted and the Pre Talk can be conducted. Alternatively, instead of a telephone, a Telephone Handset/Headset (Options: ID:800203/800204) can be connected. This has the advantage that it is possible to switch between ON AIR and PRETALK anytime. With a connected telephone this is only possible after the ’ignition’ (= caller is ON AIR) if it has not been rung off. In the ISDN operating mode only a telephone handset or a headset can be connected. Using a telephone is not possible.

The configuration and operation can be c arried out primarily via the front keypad and the illuminated display. The configuration and operation is especially comfortable via the MAGIC TH2 Software (see CHAPTER 5) included in delivery, which communicate s with the system via the RS232 interface. The most basic operating functions like accepting a call, dropping a connection and establishing a connection with a preprogrammed number can be carried out via three programmable TTL contacts. Two relays are available for status indication. Optionally, the operation can be carried out via the MAGIC TH2 Keypad (see CHAPTER 6) that can be connected to the RS232 interface instead of the PC software.

HYBRID INTO OPERATION

3.1 Mounting

With its dimensions (W × H × D) of 220 mm × 44,5 mm (1 U) × 220 mm the MAGIC TH2 system can be either used as desktop device or mounted in a 19 inch rack. Corresponding 19“ mounting brackets are included in delivery. Optionally, a mounting kit (ID: 800202) is available to implement two MAGIC TH2 next to each other

When mounting the unit please keep in mind that the bending radius of the cables is always greater than the minimum allowed value.

When the MAGIC TH2 Telephone Hybrid is installed, please make sure that there is sufficient air ventilation: It is recommended to keep a spacing of ca. 3 cm from the openings. In general, the ambient temperature of the system should be within the range of +5°C and +45°C. These limits are especially to observe if the system is inserted in a rack. The systems works without ventilation.

During operation air humidity must range between 5% and 85%.

3.2 Connection to the mains voltage

The system can be operated with mains voltage in the range of 90 V and 253 V via the external power supply adapter included in delivery. The mains frequency can range from 45 Hz to 65 Hz. The maximum power consumption is 15W. The rack must be earthed according to the VDE Regulations. This can be carried out via the earthing screw on the back side of the unit.

The unit does not have a circuit closer and a circuit breaker. After plugging in the external power supply adapter the unit boots in a few seconds. In standby mode the AVT logo is shown on the display.

In this way, you can also combine the TH2 with the products MAGIC DC7 and MAGIC AC1.

TIP

The system temperature can be indicated on the display (

Menu Status Infor-

mation

(see CHAPTER A1.4, Page 103))

ATTENTION Incorrect ambient temperature and humidity can cause functional defi-

ciencies.

Operation outside the threshold values indicated above leads to a loss of warranty claim.

PAGE 20

Putting into Operation

3.3 Earthing of the system

For EMC reasons an earthing via the earthing screw of the system must be carried out in either case.

3.4 Operating elements on the front side

The system has an illuminated graphical display with a resolution of 160 x 32 Pixels and 21 operating buttons.

On the right next to the display there are two softkeys whose current functions are indicated on the display. In the middle there are two buttons for navigation (selection upwards/downwards), two buttons for accepting/dropping calls as well as an

button. The numerical pad supports in addition to

the numericals

0...9

also the ’*’and ’#’button. For entering text the numerical

pad can also be used as a normal keypad.

The operation is similar to standard mobile phones.

3.5 Operating modes of the system

The following figures show the system in the different operating modes and their respective cablings.

3.5.1 Analogue POTS operating mode

The minimal wiring for the operation with an analogue telephone line is pictured in Fig. 4. Via the optional analogue telephone the Pre Talk can be carried out if required.

FIG. 4 MINIMUM WIRING IN ANALOGUE POTS OPERATING MODE

The maximum wiring with all options is shown in Fig. 5. The RS232 interface allows the connection with a PC with MAGIC TH2 software or the application of the MAGIC TH2 Keypad as alternative to the operation via the front keypad.

ATTENTION Earthing

If the analogue POTS interface is in operation, the system must be earthed via earthing screw for EMC reasons. If the earthing is not carried out, the Audio signal can be faulty on the caller’s side (humming).

ATTENTION Connection of an analogue telephone or a telephone handset

Please notice that the HANDSET/PHONE interface is implemented as 6-pole Western socket. Standard telephones or handsets with 4-pole Western connectors must not be used because otherwise the contacts in the socket wi ll be destroyed.

ATTENTION Connection of an analogue telephone

Please notice that in case of using an analogue telephone only Pin 3 & 4 of the

HANDSET/PHONE interface must be used. The Pins 1, 2, 5 and 6 of the interface are used for connecting the handset and must not be occupied by the telephone.

General

• Via the option Line Mode you can select the line interface. The following

configurations are possible:

Page 42

PAGE 42

Windows PC Software

– ISDN Single Hybrid: The system is operated with ISDN, but only one

channel of the two available B channels is used. If there is a call on the second channel, the system signalises ’Line busy’. Only the Audio1/AES IN/OUT interfaces (see Fig. 6 and Fig. 7) are used.

– ISDN: The system is connected to the ISDN and two independent hy-

brids are available.

– POTS: The system is connected to an analogue telephone line. In this

operating mode only one channel is available in general. Only the Audio1/AES IN/OUT interfaces (see Fig. 6 and Fig. 7) are used.

•Via the function Enable Auto Answer on Audio Line the auto answer can be activated. Under the option Current Audio Line , PRETALK, HOLD or ON AIR you can set which Audio line is activated automatically after the call has been accepted.

• It is possible to activate a ring tone as audible signal for incoming calls via the function Enable System Ringing Tone.

•If you select Enable Ringing Tone on Handset/Headset incoming calls can be signalised via the Pre Talk Audio line if a telephone handset or headset is connected.

•If the POTS 50 Hz Filter is activated, a disturbing 50 Hz humming is filtered out. The spurious signal is injected via the POTS connection in the system.The reason is in the majority of cases an incorrect cabling of the private branch extension.

• Via the slide control POTS Redial Delay it is possible to insert a pause before redialling - directly after disconnection - in a range of 0 ... 7 seconds.

Prefix number

•Under Length of internal telephone numbers the length of your internal telephone numbers is set. Subsequently, the prefix number is automatically dialled first if the length of the telephone number exceeds the length specified in this setting. If you do not want to use this function or if you operate the system with a main telephone station, enter 0.

Examples:

Length of internal telephone numbers: 3 Entered telephone number: 130 Dialling: 130

Length of internal telephone numbers: 3 Entered telephone number: 5271130 Dialling: 0 5271130

NOTICE

The following configurations are only necessary if the system is operated with a private branch exchange.

Page 43

PAGE 43

Windows PC Software

•Under External prefix number please enter the prefix number that you need to get an external line. In most cases it is 0.

• Some private branch exchanges transmit telephone numbers with prefix number to the system. If you enable the function Skip prefix number on incoming call, you can save a displayed number in the phone book without prefix number since the prefix number of the displayed number is deleted automatically.

MSN (Multiple Subscriber Number)

Normally, a MSN entry is not required. However, if you operate further units on your ISDN interface, you can allocate a certain number to a certain unit by a MSN entry. When you order an ISDN user port in Germany, you usually receive three MSN, which you can use for your connected units.

Example: You operate a telephone, an ISDN PC card and a MAGIC TH2 system using one ISDN interface. You received the following MSN from your provider: 5271011, 5271012, 5271013. If no MSN is allocated to the system, all three devices respond to an incoming call no matter which of the three telephone numbers has been called. However, if a MSN is allocated to each device, the unit only responds if the corresponding number is called. For instance, if you enter the MSN ’5271013’ for the MAGIC TH2, the system only signalises an incoming call if the subs criber has dialled the ’5271013’. This example, however, requires that you enter the same MSN for MSN 1 and MSN 2.

Please enter the desired MSN in MSN 1 respectively MSN 2. Of course, you can allocate the same MSN to both B channels. Please notice that a MSN is always entered without the area code.

In the operating mode ISDN Single Hybrid only MSN 1 can be set.

Default Audio Line

• Via the function Default Audio Line you can select which Audio line is set automatically after the connection has been dropped. The options are: PRETALK, HOLD or ON AIR.

ATTENTION You need to enter the prefix number at any rate if you work with a private

branch exchange because otherwise the system does not wait for the free-line signal. Without dialling the prefix number at a private branch extension the telephone number is transmitted too fast and no connection can be established.

NOTICE

A MSN can only be set if an ISDN operating mode is selected (see Page 41 General).

NOTICE

For some private branch exchanges the entry of a MSN is obligatory since otherwise no operation is possible. If you cannot establish a connection to a subscriber with the MAGIC TH2, however, you are sure the ISDN is working correctly, please enter a MSN on trial.

5.6.1.1.2 Signal Processing

With the option Signal Processing configurations to optimise the caller signals can be carried out. It is possible to configure the AGC (Automatic Gain Control), the Echo Canceller as well as the Expander.

FIG. 15 SIGNAL PROCESSING

Line Settings

• A separate Automatic Gain Control (AGC) can be switched on for both

channels.

Please select the desired line with your mouse and press the button Edit, which opens the configuration window. To switch off the AGC select Off. To switch it on select On.

FIG. 16 CONFIGURATION AGC AND ECHO CANCELLER

Via the button Set AGC on/off for all lines you can switch on respectively switch off the AGC for all lines.

ATTENTION An Automatic Gain Control is reasonable if you do not have the possibility

for Pre Talk during which the level can be adjusted.

But: An AGC is no wizard. Extremely low callers cannot be boosted boundlessly. Extremely loud callers cannot be toned down boundlessly.

Page 45

PAGE 45

Windows PC Software

•An Echo Canceller can be set on or set off separately for each channel.

Select the desired line with your mouse and press the button Edit, which opens the configuration window (see Fig. 16). To generally set the Echo Canceller off select Off.

If you always want to have the Echo Canceller activated select Always ON. In this case, no test tone to detect the echo is sent.

If the option Auto is selected, the Echo Canceller is switched on or switched off dynamically. The system sends a short test tone to determine if an Echo Cancelling is required or not.

Via the button Set EC on/off/auto for all lines you can select the same operating mode of the Echo Canceller for all lines.

Automatic Gain Control Settings (AGC)/Expander

The correct functioning of the AGC can be optimised via several parameters.

• Threshold : The AGC does not start before the signal exceeds the threshold value set here. The default setting is -30 dBu.

• Level :The level set here corresponds with the average desired level. Please consider sufficient head room. The default setting is -12 dBu.

• Speed : Depending on the desired speed of the level adjustment (Slow or Fast) the setting of the AGC speed can be configured here. The faster the AGC must work the more noticeable are the inconsistencies. If the set speed is too slow, the caller signal is too low or too loud on average. The default setting is Medium.

NOTICE

In general, the use of the Echo Canceller is recommended. When a subscriber calls on the hybrid with an analogue telephone, a line echo is produced which can interfere with the incoming signal. Digital telephones (e.g. ISDN or mobile phones) do not produce these line echoes. In this case an Echo Canceller would worsen the incoming signal. For this reason the hybrid sends a short test tone when a connection is established (only in the Auto mode) and detects the level of the echo. If a certain threshold value is not exceeded, the Echo Canceller is set off because the us e of a digital phone on the counterpart is anticipated. If the level is too high, the Echo Canceller is set on automatically.

But: Echo Cancellers can only suppress echoes if the delay of the signal lies within a certain scope. Telephone connections via satellite have such a long delay that the Echo Canceller cannot work properly anymore.

TIP

If your callers are put through by a Call-In-Center , you should use the option Always ON because otherwise the Echo Canceller is possibly not adjusted correctly.

In the Auto mode, the test tone is namely send between the hybrid and the Call-In-Center - and not, as required, between the hybrid and the caller. Since most of the lines of Call-In-Centers ar e digital ones, the Echo Canceller woul d be turned off internally. However, if the caller uses an analogue telephone, disturbing echoes would be audible.

Page 46

PAGE 46

Windows PC Software

•An Expander tones down the caller signal automatically, if its level falls

below a certain threshold value. The aim is to completely filter out background noises of callers who are not currently speaking.The Expander is activated by checking the respective box.

• With the use of the key Default Settings the default settings named above can be configured and the Expander can be activated.

• Under the setting HOLD signal source you can select the HOLD signal

that you want to use.

With the option ON AIR the signal which is transmitted via the AUDIO 1 respectively AUDIO 2 input interface is used as HOLD signal. In this setting no further options can be configured.

If you select Recorded Hold Signal, the caller hears the Audio signal stored in the system. The signal is identical for both lines (in ISDN operating mode).

• With the use of the slide control Pause between repetition you can set the

pause between the repetitions of the recorded signal. The pause time ranges from 0 to 30 Seconds.

HOLD signal recording

• To record a HOLD signal you can select the line on which the signal is recorded under Record source. The options are: Audio 1, Audio 2 or Hand- set/Headset.

• Via the button Start you start the recording. With Stop the recording is stopped. With Save the recorded signal is saved in the permanent memory (FLASH-EPROM) of the system.

– External: The AES/EBU output clock is derived by the external clock

connected via the interface Audio 2/CLK IN. The clock rate of the connected clock must be 48-kHz.

– Recovered: The AES/EBU output clock is derived from the digital in-

put signal of the interface Audio 1/AES IN. This configuration is usually to be selected if you use the digital input of the system. In this way a synchronous functioning of the transmission chain is ensured

• If you operate the input or the output in an analogue mode, the corresponding slide control for adjusting the nominal Audio level of the ON AIR interface (ON AIR Nominal Level) is displayed. The nominal level

NOTICE

The AES/EBU input always works with recovered clock, therefore a configuration of the output is required. For clock synchronisation to other systems you can use the Audio output Au- dio 2/CLK OUT. The clock rate of the output clock is 48-kHz.

can be adjusted separately for the input (Level In) and for the output (Level Out) in the range of -3 ... +9 dBu in 1-dB steps. The head room is 6 dB in general. If you want to have the maximum level of 15 dBu for the system, you must set 9 dBu as nominal level. The default settings are 0 dBu.

• If you configured the PRETALK interface for a Handset/Headset (see

Page 52, Pretalk Interface), two slide controls for the Audio level adjustment are displayed. Under Handset Nominal Level you can set the Audio level separately for the input (Level In) in the range of -24 ... +6 dBu and for the output (Level Out) in the range of -6 ... +6 dBu in 1-dB steps. The defaults settings are 0 dBu.

• Via the slide control Audio Level Offset it is possible to increase or decrease digitally the caller signal level in a range from -16 ... +15 dB.

• To set all parameters to default values press the Default Settings button.

5.6.1.2.4 Relay / TTL

The MAG IC TH2 system incorporates three GPIO Pins (TTL) which can be programmed separately as input or output. Additionally, two Relays are available.

The operating mode of a TTL-Pin - Input or Output is selected via the option Direction.

The following specification accounts for all three configuration windows TTL1, TTL2 and TTL3.

TTL-Pin as input

FIG. 23 TTL-PIN AS INPUT

If you use a TTL-Pin as Input, you can program two different functions separately when edges change:

• Positive edge: The event is activated when the voltage on the TTL-Pin changes from 0V to+5V.

• Negative edge: The event is activated when the voltage on the TTL-Pin changes from +5V to 0V.

The following functions can be configured (Function Code): – Idle: No function, the Pin is not used. – Call Out/Accept Call In:

Via this function you can establish a connection to a certain Phone Number. Under Line you select the line (Line 1 or Line 2) on which the connection is established (only in the ISDN operating mode). Under Audio Line you select the Audio line (PRETALK, HOLD or ON AIR) which is activated when the partner accepts the call.

Page 58

PAGE 58

Windows PC Software

– Drop: If you activate this function, a connection on the selected line

(Line 1 or Line 2) can be dropped.

– Load Preset: Via this function it is possible to load a preset which you

have to select under Preset.

– Set Audio Line: This option allows a switching on a certain Audi o line

(PRETALK, HOLD or ON AIR), which you must set under Audio Line. In the ISDN operating mode you must additionally select the desired Line.

– Connect via DTMF/Accept Call In: The system supports the connec-

tion via DTMF tones (Option, see CHAPTER 8), which are fed in via the inputs AUDIO 1 IN/AUDIO2 IN. The call initiation is realised by this function so that the systems knows when the phone number is complete. Under Line you set the line (Line 1 or Line 2) on which the connection is established (only in ISDN operating mode). Under Audio Line you select the Audio line (PRETALK, HOLD or ON AIR) which is activated when the partner accepts the call. If the system receives a call, it can be accepted on the selected line via this function. The Audio interface is activated according to the configuration.

– Connect Level Triggered : After selection this funtion the call initia-

tion is realised by a static level (+5V = configuration under Positive Edge or 0V = configuration under Negative Edge) instead of a edge triggered level (see above).

Example 1:

You want to accept a call on line 1 with TTL 1. The caller is to be switched directly in the ON AIR mode. After the conversation has been finished the connection is to be cleared with TTL 1.

Programming:

Positive egde:

Function Code: Call Out/Accept Call In Audio Line: ON AIR Line: Line 1 Phone Number: -

Negative egde:

Function Code: Drop Line: Line 1

FIG. 25 TTL-PIN AS OUTPUT

If a TTL-Pin is configured as Output, the event is signalised as change of voltage on the TTL-Pin from 0V to+5V.

Under Positive edge you can select one of the following Function Codes:

– Fixed to Low (0V): The TTL-Pin is set to 0V permanently.

– Fixed to High (5V): The TTL-Pin is set to +5V permanently.

– Connection Status: Via this function you can signalise the connection sta-

tus of a line. Select the connection status u nder Status. The following configurations are possible:

– Disconnect – Calling – Incoming call – Connect

Under Line (only in the ISDN operating mode) you select the line whose status you want to signalise. In addition to Line 1 and Line 2 you can monitor the connection status of both lines if you select the option All Lines. As soon as one of the two lines meets the criteria, the signal is set on the TTL-Pin.

ATTENTION Please pay attention to the maximum switch current of 10 mA respectively

the maximum switch voltage of 5V per TTL output.

You can read the files with any text editor.

The following events can be activated: – Line Events (ISDN/POTS): All line events (link connection and discon-

nection) are recorded.

– Internal Events: All internal events are recorded in the log file (e.g.

RS232 connecting error).

– Alarms: All alarms are recorded.

FIG. 47 EXAMPLE LOG FILE

•Under System Logfile you can create a detailed ISDN log file .

– ISDN Layer 1: Physical Layer: All messages concerning the physical ac-

tivation/deactivation of the ISDN interface are stored in this layer.

– ISDN Layer 2: Data Link Layer: The main task of the data link layer is

to take a raw transmission facility and transform it into a line that appears free of transmission errors in the network layer.

This layer should only be activated for the log file if there are potential problems. Please notice that if this layer is enabled an entry is generated every 8 seconds and therefore the memory is filled quickly.

– ISDN Layer 3: Network Layer: The Network Layer enables that a con-

nection between two subscribers is established by adequate addressing. This layer is the most important one for the logging since all connection data is recorded here.

The system saves all messages of the activated ISDN Layer. The internal memory capacity is 128-kByte

. The data is filed cyclically.

NOTICE

The log file is created by the PC software. If the PC software does not run, the logging is not continued.

An entry in the ISDN protocol is about 15 Byte on average.
