Page 10: The Isdn Connection
1. 1 The ISDN Connection With the european DSS1 (Euro-ISDN) protocol, you initially need one S connection (or two connections if you want to run an ETS-4308 I with a second external S port). 1. 1. 1 The Type of Connection Your PBX is designed for the following types of connection: Basic access as a point-to-mulitpoint (PTMP) connection. -
Page 11: Opening And Assembling The Housing
Use the four screws and pegs supplied with the PBX to fasten the base by means of the fastening holes in the corners of the base plate. You should use the drilling template for AUERSWALD PBXes to mark the positions of the holes. IMPORTANT: For safety reasons, you must not remove the PCB with mounted com- ponents from the housing. -

Page 20: Connecting To A Computer/Printer
1. 10 Connecting to a Computer/Printer Your PBX has an RS-232-C, V.24 serial port. Using this interface allows you to conveniently program the system from an IBM or compatible PC. Apart from this, you can use the serial port to output directly the list of calls and charges. Connecting a serial printer to the port allows you to output a hard copy of these lists too. -

minal PC-GND. After this plug the SUB-D socket into the mating connector on your computer or printer. Distances above 10 meters can cause problems even if you use screened cables. It is not possible to guarantee correct functioning, since performance can be affected signif- icantly by the way in which the cable is routed and the condition of your computer interface. -

This is how to connect your PBX to the ISDN connection: Plug one end of the supplied ISDN cable into the RJ 45 (Western) socket labelled either “Amt” (Exchange) or “zum NTBA” (To NT) on your PBX. If you have an ETS-4308 I with a second external S port, plug the cable into one of the available sockets on the left-hand expansion module. -
Page 26: First Use
2. 1. 3 First Use The programming switch in the system must be in “Programmieren erlaubt” (Programming allowed) setting when you are programming the PBX by telephone. Before putting the PBX into operation, ensure that the lid is closed. Plug in the 230-V mains cable of your NT if it is fitted with one. -

To be able to make internal calls on a direct external telephone, to use abbreviated dialling numbers or to carry out programming steps, you must first press the star ( ) key. -

Page 46: Entering Abbreviated Dialling Numbers
3. 8 Entering Abbreviated Dialling Numbers Abbreviated dialling numbers primarily make it easier for you to dial. You can store numbers that you use often as three-digit abbreviated numbers that you punch in directly after lifting the handset. After this, the PBX automatically dials the access digit and the stored calling number. -

Page 48: Querying A Calling Number From The General Abbreviated Dialling Memory
When entering digits, if you pause between entries for five or ten seconds the system saves these pauses too, i.e. as a two- or a twelve-second pause. When you program a pause, the system emits a brief tone after five and ten seconds to indicate that the desired pause has been accepted. -
Page 49: Entering Private Abbreviated Dialling Numbers
3. 8. 5 Entering private abbreviated dialling numbers Each user is allowed to program ten private abbreviated dialling numbers. In each case, the abbreviated dialling numbers 100 to 109 are available for this. However, these numbers can only be dialled at the telephones at which they are programmed. This means that you must program a private abbreviated dialling number on the telephone set at which you want to use it. -
Page 50: Setting The Time
3. 10 Setting the Time Your PBX needs to be told the current time for the wake-up and day/night mode switching functions. Normally the system automatically updates the time on each subscriber-initiated external call, assuming that the exchange transfers the time. If this does not apply in your case, you can also use this programming function to enter the time. -

Page 52: Setting The Wake-Up Time
3. 11. 1 Setting the wake-up time You use the following programming step to set a wake-up time for a party. The PBX retains this wake-up time until you carry out this programming step again for the same party. In this connection, the wake-up time is activated for a one-off wake-up call. -
Page 53: Day/Night Mode Switching
3. 12 Day/night mode switching The PBX allows you to make different settings in the user program for some day and night operation functions. The following function allows you to specify whether you want to acti- vate and deactivate day and night operation time-controlled by the PBX's internal clock or whether you want this to be carried out manually at appropriate times, e.g. -
Page 54: Charge Transfer (For Analog Extensions
3. 13 Charge Transfer (for Analog Extensions) The PBX can switch the call charge signal individually for analog extensions. This allows parties to register the charges for external calls on their own telephone set (assuming that the telephone set has a charge display capability). It is not, however, possible to check exactly the number of charge units, since during a query from an external call, for example, the call charge signal cannot be clearly assigned to one or other of the calling parties involved. -
Page 55: Call Data Recording
3. 14 Call Data Recording The PBX can record all external calls in a memory buffered against power failures. The system records the following data per call: External calling number, maximum of 20 digits. Identification: successful/abortive. Identification: business/private. Identification: coming/going. Extension number. -
Page 56: Printing Charge And Call Data On Demand
You can do without stopping. In this case, you must, however, be aware that the data is lost of the calls that were carried on in the meantime. In the serial printer that you are using, you must set the parameters of the serial port (no protocol, 9600 bps, 8 data bits, 1 start bit, 1 stop bit, no parity). -

3. 18 Activating alarm (ETS-4308 I only) The ETS-4308 I PBX has an alarm input. If this input's two connections (ALARM and GND) are connected together, the system issues an alarm (for more details on the switching input, refer to Chapter Technical Data on page I-82). - Page 63 If necessary, the system repeats this alarm cycle up to ten times. Instead of the two-tone signal that the ETS-4308 I generates, it is also possible to use an answering machine with an appropriate recorded announcement (see user program/in the default setting, an answering machine is not used).
- Page 64 DDI in the case of a PTP connection. For more information on how to acknowledge (deactivate) an alarm once it has been trig- gered, refer to Chapter Acknowledging a triggered alarm (ETS-4308 I only) on page B-24 in the Operator’s Manual.

Page 66: Choosing The Dial Tone Mode
3. 19. 2 Choosing the dial tone mode You can choose between three different internal dial tones, i.e. continuous dial tone, exten- sion dial tone or special dial tone, which you can set at individual extensions. The dial tone that you set here can only be heard when the calling party lifts the handset (not with direct external telephones). -
