Universal telephone interfaces: What are the models?

The models are:

Article 3531 (for Sound System technology)

Article 3532 (for Two Wire technology)

Article 3533 (for Digibus technology)

 

Universal telephone interfaces: General characteristics

The universal telephone interfaces are designed above all to enable telephone switchboards not produced by Elvox to interface with Elvox audio and video door entry systems. The technologies involved in the connection are Sound System, Two Wire and Digibus. The interfaces are analogue and passive, so they must be connected to the telephone switchboard as extensions.

If for connection requirements the interface uses an urban line, the active interface article 3530 must also be connected to the universal interface.

 

Open voice telephone entrance panels: General characteristics

Open voice telephone entrance panels are analogue telephones installed inside panels used normally for audio or video door entry systems. All the entrance panel models have LEDs under the transparent glass, for displaying the telephone panel engaged/free and programming status. The panels are self-powered from the telephone line and can be connected to a switchboard or the PSTN (analogue) telephone network by means of a telephonic pair.

All models of entrance panels can be programmed locally or remotely by sending DTMF codes.

After programming the telephone number on the corresponding key, calls are made by pressing the same key. A maximum of 5 keys can be used for programming telephone numbers. Dialling is in multi-frequency and the max. length of each stored telephone number is 32 digits. Two telephone numbers can be programmed on each key, selectable according to the set profile. There can be 3 set profiles, characterised as: profile 1 memorisation of first telephone number, profile 2 memorisation pf second telephone number, profile 3 selection of call routing to first profile and if it is engaged routing of call by dialling the number memorised in the second profile. The profiles can be both programmed and activated from a remote telephone. The panels are equipped with 2 micro relays with a maximum capacity of 1 A - 30 V usable for services such as "door lock release" and "automatic gate opening", which can be activated by either a local or remote telephone. The series 80T5 entrance panel is equipped with a numerical keypad for making standard telephone calls.

 

Telephones art. 3562 - 3597: How are the dedicated keys (key, lamp, square) programmed?

For telephone 3562:

The keys with the key, lamp and square symbols already have the codes for interphone controls memorised. Different codes can be memorised by keying in the following programming string on the telephone 3562.

P, ME, 1,2,3, n° tel. P

Where:

P = the telephone key with arrow and rhombus symbol (indicates the entrance being programmed).

ME = the button located inside the telephone on the printed circuit (it must be pressed to memorise the codes).

1,2,3 = the direct memories M1, M2, M3 (key, lamp, square).

tel. no. = the new code to be memorised

On telephone 3562 it is possible to enable or disable the interphone control function on the dedicated keys. The programming string is the following:

P, *, x, P

Where:

X = 1 enables the interphone control dedicated key service.

X = 2 disables the service, the keys become direct memories allowing various numbers to be memorised for controls.

P = the telephone key with arrow and rhombus symbol (indicates the entrance being programmed).

Reset is performed by keying the following codes in sequence into telephone 3562:

P, R, 000.

For telephone art. 3597:

The keys with the key, lamp and square symbols already have the codes for interphone controls memorised. Different codes can be memorised by keying in the following programming string on the telephone 3597:

(arrow with rhombus), M1 (key), R2, R, 1, R, (arrow with rhombus).

(arrow with rhombus), M2 (lamp), R2, R, 2, R, (arrow with rhombus).

(arrow with rhombus), M3 (square), R2, R, 3, R, (arrow with rhombus).

The settings must be programmed after inserting the battery provided in the appropriate housing.

Reset is performed by keying the following codes in sequence into telephone 3597:

(arrow with rhombus), R, 0, (arrow with rhombus).

BCA ANALOGUE TELEPHONES WHICH DO NOT HAVE DEDICATED KEYS FOR INTERPHONE FUNCTIONS CAN STILL BE USED. THESE FUNCTIONS CAN BE OBTAINED BY PRESSING IN SEQUENCE ON THE TELEPHONE THE KEYS 1 R FOR THE "KEY" COMMAND, 2 R FOR THE "LAMP" COMMAND, 3 R FOR THE "SQUARE" COMMAND.

 

Telephones art. 3562 - 3597: Main characteristics of Elvox telephones

Elvox telephones are analogue BCA telephones capable of calling telephone numbers in either Decadic and Multifrequency mode with various characteristics. The special feature of these telephones is the presence of 3 dedicated keys for interphone functions that can be performed only by interfacing these interphones/telephones with Elvox telephone switchboards.

Telephone switchboard art. 3511: How is the “Follow Me” service programmed and how are the controls activated remotely?

The telephone number is programmed on the switchboard as follows:
R * * * 12 * (telephone or mobile phone number) *

Remote controls:
Call the switchboard 3511 from a remote telephone, wait for at least 5 rings to allow the call to be forwarded. After the fifth ring, a beep sounds indicating that the system password (1234) can be keyed in, followed immediately by the number:

0 = continue the conversation for another 30 seconds.

1 = activates the door lock release for a few seconds (auxiliary 1)

2 = activates an impulse to open the gate (auxiliary 2)

3 = activates an impulse to turn on the stair light (auxiliary 3)

4 = activates auxiliary 4

5 = deactivates auxiliary 4

*= activates remote control

#= deactivates remote control

When operating the telephone switchboard 3511 with the "Follow Me" service activated, it is possible to perform the auxiliary activation controls only after the first minute of audio connection and after the beep indicating continuation of the conversation.

 

Telephone switchboard art. 3511: Accessory 352T

Accessory type 352T enables the controls to be activated remotely and/or the interphone call to be diverted ("Follow Me" service). The status of the services can be seen by the illumination of two red LEDs.

Telephone switchboard art. 3511: How many telephones can be connected together in parallel?

The switchboard allows one urban line and up to 3 telephones to be connected in parallel.

Telephone switchboard art. 3511: Main characteristics of switchboard 3511

The characteristics are:

a) Possibility of conversation between telephone and external line or between telephone and interphone speech unit. The two types of conversation are alternatives.

b) Prevalence of communications towards the external telephone line (default) or towards the telephone switchboard.

c) Transfer of interphone call to urban line towards a programmed number with signalling of function being performed.

d) Control of auxiliary "door opening", "gate" and "stair light on" functions during interphone conversion, during external line conversation and at rest.

Remote control of auxiliary functions through password protected procedure

 

What needs to be done in the event of a malfunctioning switchboard?

If the switchboard malfunctions, it is advisable to call an authorised Elvox service centre by telephone. If repairs are necessary, the switchboard must be sent to the Elvox area agency or to the wholesaler (where the purchase was made), who in turn must send it to the Elvox headquarters. If necessary, you can ask for an estimate of the repair costs by calling 049-9202590.

How does the switchboard behave in the event of a power failure?

In the event of a power failure to the switchboard, urban line 1 is routed to internal number 41 while urban line is routed to internal number 45.

Can more than 8 telephones be connected to the switchboard?

A further two telephones can be connected to the switchboard in addition to the 8 extensions already present, making a total of 10. If the number were to be increased further, the switchboard would be unable to allow all the telephones to ring simultaneously.

Can non-Elvox analogue and cordless telephones be connected?

BCA analogue and cordless telephones of any make can be connected to the telephone switchboard. In the event of a malfunction of key R it is possible to correct the "calibrated opening" time and set new values on the telephone switchboard.

Does the Elvox switchboard require special telephones?

Dedicated multifunctional telephones are not required. All BCA analogue telephones are sufficient for the functions required by an Elvox telephone switchboard. Elvox dedicated telephones are also used for interfacing between a telephone switchboard and an Elvox audio or video door entry system.

Programming switchboards: Special program settings for door entry systems?

For the interphone function in the telephone switchboard two settings are possible.
The first setting 98 1234 66 1 R allows the interphone call ringtone to be changed, switching from one ring on pressing the call button to a ringtone consisting of two rings repeated every 5 seconds for a duration of 30 seconds.
The second setting concerns the duration of the excitation time of the relay connected between terminals 12 V and B of the interphone interface.
The duration is between 1 and 50 seconds. The setting is 98 1234 67 yy R. Where yy is the number of seconds to be set (01......50).

Programming switchboards: How is the “Telephone call transfer” programmed?

An incoming call to the switchboard can be transferred externally only if there are two telephone lines by programming the switchboard as follows:
1 - Program the "direct call" and "private line" functions for both lines
98 1234 61 2 5 R
98 1234 62 2 5 R

2 - Activate the function with 911 R

3 - Program quick-dial number 30
98 1234 30 yyyyyyyy R

4 - Activate the function with 961 R (960 R to deactivate).

With these switchboard settings, the telephone line is no longer engaged by pressing "0" but by pressing "20".

Programming switchboards: How are the quick-dial numbers programmed?

The quick-dial numbers are programmed as follows:
From extension 41 enter the sequence 98 1234 nn yyyyyyyyyy....R.
Where:
nn = The numbers starting with 00 and running to 39.
These quick-dial numbers must begin with the number 3. So in the table of quick-dial numbers, for 00 in reality you have to key in the number 300, with the quick-dial number 01 the number 301, with 02 the number 302, etc.
yyyyyyyy = The telephone number that is to be called with the given quick-dial number.
The quick-dial numbers set in 36, 37, 38 and 39 are also used for the "Hot Line" service. The quick-dial number 30 is also used for the "Message present warning" or "External call transfer" service.

Programming switchboards: How are telephone extensions programmed?

The telephone extensions present on the switchboard may be programmed for special functions or for simple functions. Special functions are programmed from telephone 41 and follow the indications of TABLE 1 in the instruction manual. Simple functions are programmed directly on the extension.

Programming switchboards: How is the switchboard programmed for changing recognition of calibrated opening?

This programming enables the switchboard to recognise key R present on telephones of different makes and needs to be carried out if the telephone switchboard performs no command or breaks off audio communication when key R is pressed.
Calibrated opening recognition is changed by programming on the switchboard the function:
98 1234 9x extension no. without 4 R
Where:
9x = Selects the time (depends on telephone model). The programming codes 97 or 98 modify calibrated opening recognition.
Code 97 is normally entered for fixed telephones, code 98 for cordless telephones.
97 = change to 50 - 160 ms
98 = change to 80 - 800 ms
Both settings can be programmed to extend recognition to the range
50 - 800 ms (98 1234 97 d R 98 d R).
A number of telephones can be programmed in sequence, e.g.: 98 1234 98 or 97 41,42,43,44,45,46,47,48 R.
extension no. without 4 = the extension number such as 42 must be programmed without the initial number 4, i.e. entering only the number 2.

Programming switchboards: How is the Fax Switch function (automatic fax recognition) programmed?

The recognition (Fax Switch) function is programmed as follows.
From extension 41 key in:
98 1234 61 2 R (for urban line 1)
98 1234 62 2 R (for urban line 2)
This setting assumes that faxes arrive on both lines.
Set the fax extension.
98 1234 80 extension no. R.
Activate the service by keying in code 911 R from any telephone.
After entering the activation code 911 R you should hear a voice message indicating that the direct call service has been activated.
Code 910 R deactivates the direct call service and therefore the fax-switch function.

Programming switchboards: How is the interphone system connected to the telephone switchboard?

The interphone interface included in the switchboard allows Elvox interphone systems to be connected with Sound System or A.C. calls.

The wires that need to be connected are the audio wires (1-2-3), the call wire (6) and the lock return wire (S or 7).

 

Programming switchboards: How should the switchboard be programmed to separate the two telephone lines?

If the telephones are to be divided up equally for each home, the programming is as follows:

98 1234 41 2 R, 98 1234 42 2 R, 98 1234 43 2 R, 98 1234 44 2 R
These settings totally disable the urban line 2 on extensions 41, 42, 43 and 44.

98 1234 45 1 R, 98 1234 46 1 R, 98 1234 47 1 R, 98 1234 48 1 R
These settings totally disable the urban line 1 on extensions 45, 46, 47 and 48.

 

Programming switchboards: How should the switchboard be set to operate with a single telephone line?

Jumper S2 must be moved according to the model of telephone switchboard. For switchboard models 35M8 or 35T7, the jumper S2 must be in the up position as S1. For switchboard model 3528/N, the jumper S2 must be in the down position as S1.

Programming switchboards: Can all the telephone calls be sent to a single extension that serves as a post-operator?

The switchboard must be programmed for the night-time service.
From extension 41 enter the sequence: 98 1234 (extension no.) 5 R
The number 5 indicates night-time service for line 1.
98 1234 (extension no.) 6 R
The number 6 indicates night-time service for line 2.
The night-time service is activated by keying in code 901 R from any telephone. Key in 900 R to deactivate. If the night-time service is activated, all the telephone calls must be sent to the extension set in the programming. There may be more than one extension telephone.

Programming switchboards: How can be interphone or telephone call be disabled?

The code 80 R must be keyed into the relevant telephone. A voice message saying "ringtone deactivated" is heard, indicating that all the ringtones have been deactivated. To restore the ringtone of urban line 1 key the code 81 R into the telephone; to restore the ringtone of urban line 2 key in 82 R; to restore both ringtones, key in 83 R; to restore the ringtone of the interphone call key in 84 R.

For extension number 41 only it is necessary to include initially different programming so as to be able subsequently to program 80R, 81R, 82R, 83R and 84R.

This programming which applies only to extension 41 is the following:
98 1234 * 4 0189 002 R

 

How are telephone calls distinguished from intercom or interphone calls?

Urban telephone calls, intercom and interphone calls are distinguished only by the pause time between rings.

Automatic incoming fax recognition

By programming the FAX-SWITCH function it is possible to enable the switchboard to recognise incoming faxes without ringing the telephones.

How can the switchboard programming be reset?

The telephone switchboard can be reset to default values in various ways.

A reset can be performed with telephone 41 by means of the following settings: 98 1234 99 R.
This reset operation removes generic programming from the switchboard but does not affect the factory settings or hidden settings.


The second is always performed with telephone 41 by means of the following programming:
98  *##* 55 * * R
This reset operation goes to the heart of the switchboard, eliminating both hidden and generic programming. The factory settings remain unchanged.

If telephone 41 is not accessible and it is not possible to perform the first or the second reset, a manual reset can be performed by means of the following procedure:
a) Disconnect the switchboard from the power supply.
b) Move jumper S2 to the down position (2-3), leaving terminal 1 free.
c) Short circuit terminal 1 of S2 together with terminal 1 of S1.
d) Connect the switchboard to the power supply while maintaining the short circuit between the terminals. After a few seconds a reset click should be heard.
e) If the switchboard requires the presence of both telephone lines, disconnect the switchboard from the power supply and return the jumper S2 to position (1-2).

For articles 35M4, 35M8, 35T4 and 35T7 the manual reset procedure is as follows:
a) Disconnect the switchboard from the power supply.
b) Move jumper S2 to the up position (2-3), leaving terminal 1 free.
c) Short circuit terminal 1 of S2 together with terminal 1 of S1.
d) Connect the switchboard to the power supply while maintaining the short circuit between the terminals. After a few seconds a reset click should be heard.
e) If the switchboard requires the presence of both telephone lines, disconnect the switchboard from the power supply and return the jumper S2 to position (1-2).

 

How is it possible to check operation of the Elvox switchboard?

After connecting the telephone switchboard to the 230 V - 50 Hz mains power supply, check that a continuous tone is present on every extension. Intercommunication between extensions confirms that the internal telephone system has been connected correctly.

What are the characteristics of Elvox switchboards?

Elvox telephone switchboards handle a maximum of 2 urban lines and 8 internal extensions. Extensions allow for the connection of analogue telephones, cordless telephones, a fax and an answer machine. Dialling can be either decadic or multifrequency. The maximum number of simultaneous conversations is 2 external, 2 internal and one interphone. The system has on-hold music and an interphone interface that allows the telephone to perform all the functions of the interphone system including door lock release as well as a further two auxiliary functions.

How is the NT1-PLUS terminal block programmed with an Elvox telephone switchboard?

The terminal block is programmed by the telecom company technicians. The settings that must be programmed on the terminal block are linked to the ISDN line by way of a single number. In this case the call must leave the terminal block with alternative distribution, in other words an incoming call must ring just one telephone at a time. The called user must engage the first free line, while a second call must engage the second free line.

Operation in which both telephones ring simultaneously is not correct.

 

Functionality between the Elvox telephone switchboard and the ISDN digital line

The Elvox switchboard is an Analogue switchboard and cannot be connected to the ISDN line. In this case the telecom company installs a NT1PLUS terminal block on the digital line, which transforms the ISDN line into two analogue lines with a single number or a double number.

What is the function of an ADSL filter?

The ADSL filter is used when disturbance occurs on the line (e.g. crackle over the voice or broken connections), which often occurs when connected to the internet while making a telephone call. The filter must be installed between the telephone line and the point where the line enters the telephone switchboard.

What are the characteristics of an ADSL line?

The most important characteristic of an ADSL line is that it provides an internet connection while at the same time allowing telephone calls to be made and received. This is possible because the data are transmitted at a higher frequency to that used for voice transmission (300-3400 Hz), which is why it is referred to as "broadband".
