General information Information on the proper operation and usage of the telephone system - In some specific frequency domains, a high electrical interference field strength may have an impact on the transfer quality of internal and/or external telephone communications - for the duration of the interference. The sort and the extent of the impact depends on the characteristics of the connected terminal equipment.
Introduction What is the ISDN telephone system tiptel 31 home designed for? Congratulations and many thanks for purchasing the ISDN telephone system tiptel 31 home. The telephone system serves as a linking element between your analog terminals - such as telephone, fax machine or modem - and the digital telephone network (ISDN). This allows the further usage of your existing analog terminal equipment - as those devices cannot be connected to the ISDN network directly.
Introduction - Activation/deactivation of the call number display for incoming calls (COLP/COLR) programmable per extension.
Initial operation - step by step It is important to unplug the AC adapter as well as the ISDN connecting cable before taking out installation tasks at the internal line network. The installation must be done professionally. Step 1: Installing the device (wall mounting) The ISDN telephone system has to be installed in a dry room with an ambient temperature range between 0oC and 40oC. The telephone system can be used as a table-top or a wall mounted model. Follow the steps below for wall mounting: 1.
Initial operation - step by step Step 2: Connecting the terminal equipment (continued) Analog telephones with pulse or tone dialling can be connected to the ISDN telephone system. The dialling mode is recognised automatically. For telephones with specific plugs an individual adapter may be required. If you connect telephones with charge counter, a charge pulse can be assigned to the corresponding telephones.
Initial operation - step by step Step 4: Entering MSNs (optional) If you enter multiple subscriber numbers (MSNs) in your telephone system, the individual MSNs can be addressed separately and selectively. As soon as one or more MSNs are entered, only the telephone system terminals with the entered MSNs will ring in the case of an incoming call. Up to 6 MSNs can be entered. As for the entry, the MSNs are addressed by an index.
Initial operation - step by step Step 5: Designated ringing signal for individual terminals in the case of incoming calls If the connected terminals shall react selectively to a specific MSN, this must be determined as follows. The assignment of extensions to the MSNs is done as follows: 1. Pick-up the handset. 2. Dial code number for programming. 4. Dial code number for assignment to the extension. 5. Enter extension number. You hear the programming tone. You hear the dialling tone. 6.
Internal telephone calls Step 5: Designated ringing signal for individual terminals in the case of incoming calls (continued) If you connect a fax machine, the function "automatic access to the public exchange" and "access to the public exchange with bearer capability fax group 2/3" will be very useful (see "Configuration via telephone"). Example: If there is an incoming call for the third or fourth MSN, the telephone at extension 3 shall ring: Internal dialling You can make internal calls as follows: 1.
External telephone calls Access to public exchange and dialling Make external telephone calls as follows: 1. Pick-up the handset. 2. Dial code number for access to public exchange. 3.

The call forwarding function is activated.
Feature functions Call deflection (CD) In principle, the call deflection function corresponds to the call forwarding. As for call forwarding, the incoming call is transferred automatically via the exchange office. In the case of call deflection, the telephone system initiates the call transfer. If there is an incoming call for the MSN for which CD is activated, the telephone system transfers corresponding commands to the exchange office.
Feature functions Automatic call-back on busy (CCBS = completion of call to busy subscriber) The ISDN telephone system supports the ISDN feature "automatic call-back on busy" (CCBS). If you make an external call and the target subscriber is busy, you can request an automatic call-back via the exchange office - informing you on when the desired subscriber is free again. Then, pick up the handset and the subscriber will be called back automatically.
Feature functions Keypad protocol Some exchange offices use the "keypad protocol" to program features (e. g. call forwarding). Here, keypad information are sent with reference to an MSN to be indicated. The following signs which can be transferred to the exchange office for keypad control are as well as and . The exact number sequences and thus the programming parameters within the exchange office are informed by your telecommunications provider.
Configuration via telephone Accessing the programming parameters The parameters of the ISDN telephone system can be adapted to the user requirements: 1. Comfortably, via the Windows software from the scope of supply (recommended, see "Telephone system configuration via Windows software"). 2.

You can consider free variable parameters ( button) which will stand for any number ranging from 0 to 9. 1. 2. 3.
Configuration via telephone Charge pulse The exchange office transfers charging information which are converted to a 16 kHz charge pulse by the ISDN telephone system. Connected telephones can use the charge pulse to determine the charges incurring for calls (see also " Entering the charge factor" and operating instructions of the individual terminal equipment). The telephones must be able to evaluate the charge pulse.
Configuration via telephone Entering the charge factor Whether the incurring charges for outgoing calls are transferred as units or as a fixed amount mainly depends on your local telecommunications provider and the situation. If units are transferred, those can be directly converted to charge pulses by the telephone system. If amounts are transferred, the telephone system has to convert those in the corresponding number of charge pulses applying a charge factor (see also "Charge pulse").
Configuration via telephone Calling line identification presentation/restriction for outgoing calls (CLIP/CLIR) As for outgoing external calls, you can transfer your own telephone number to the called party (CLIP) or restrict the transfer of the number (CLIR). The MSN you selected for outgoing external calls will be transferred to the called party when CLIP has been programmed. In order to support the number transfer, your ISDN access must provide the feature CLIP/CLIR.
Configuration via telephone Connected line identification presentation/restriction (COLP/COLR) When you get an incoming call from an external party, you can determine whether your telephone number shall be transferred to the calling party (COLP) or not (COLR). When COLP is set, the calling party gets the MSN you selected for outgoing calls displayed at his/her telephone. In order to support the number transfer, your ISDN access must provide the feature COLP/COLR.
Configuration via telephone CLIP at internal analog terminal equipment It is possible to display the telephone number of a calling party at analog terminal equipment, if the connected terminal is suitably equipped (analog CLIP). It is only possible to display the calling party's telephone number at analog terminals if: 1. CLIP (ISDN) on the calling party's side is active and supported. 2. CLIP analog is set in the ISDN telephone system - for the extension in question 3.
Configuration via telephone CLIP at internal analog terminal equipment (continued) In step 4, the extension is selected as follows: 24 25 26 extension 1 extension 2 extension 3 The function "CLIP analog" can be activated (= 1, number is displayed, factory pre-set) or deactivated (= 0) (step 5). Example: CLIP analog shall be activated for extension 2. The PIN is set to 1234.
Configuration via telephone Setting the procedure to receive call numbers at the internal analog terminals The procedure for receiving telephone numbers at analog terminals is not standardised. The ISDN telephone system supports the DTMF (Dual Tone Multi Frequency = tone dialling) as well as the FSK procedure (FSK, Frequency Shift Keying = modem transmission procedure) for the number transfer.
Configuration via telephone MSN assignment for call number identification for external calls You can store up to 6 multiple subscriber numbers (MSNs) in the telephone system (see "Entering multiple subscriber numbers (MSNs)"). The MSN to be displayed in the case of an external call can be set individually for each extension.
Configuration via telephone Call waiting When you are holding an internal or external call while there is another incoming call for you on that line, you will hear a call waiting signal. This is identified by a signal tone which is heard through the handset. You now have the option to answer the waiting call (two-line operation with hold / three-party conference). Proceed as follows to set the call waiting function ON or OFF: 1. Pick-up the handset. 2. Dial function code for programming.
