3 ISDN - Analogue Converter Installation Manual Description The D0700 is a converter that allows control panels, Dualcom, digtal communicators and other PSTN analogue telephone equipment to connect to an ISDN2 telephone line. The board is small and fitted with self adhesive feet so that it can be installed in most control panels or other security enclosures. The unit is supplied with a 1-metre cable for connection to the ISDN Network Termination Point (NTP). The unit has a two-wire analogue line allows connection to the control panel or other equipment etc A 12-volt supply is required, normally from the auxiliary 12-volt output on the control panel. The unit monitors the ISDN line to the telephone exchange. If this fails, it is indicated to the control panel (or other equipment) connected to the analogue line. The Line Snatch feature allows the control panel (or other equipment) connected to the analogue line, to make a call even when both channels of the ISDN line are in use on other calls. The unit may be programmed with its own Multiple Subscriber Number (MSN). Note: The D0700 is designed for an ISDN2 telephone line. It is not suitable for connection to ISDN30 or ADSL lines.

5 Installation 1. Install the D0700 in the control panel or other security enclosure where the analogue telephone connection is required. 2. Connect the D0700 analogue line to the analogue PSTN telephone line connection on the control panel s digi-modem (or the Dualcom A and B terminals). Where the analogue line is supplied with connectors on both ends, cut off one connector. Cut off the two outer wires and use the inner pair of wires to connect to the control panel s digi-modem. 3. Using the supplied Cat5 Patch Lead, plug the lead onto the D0700 ISDN connector. Longer cables are available as Cat5 cables from many electronics or PC suppliers. 4. Plug the other end of the Cat5 Patch Lead into the S-bus connector on the ISDN NTP (Network Termination Point). The NTP will be supplied by, and fitted by your telecoms service provider. 5. Connect the D0700 red and black power leads to a 12 volt supply (normally the Aux 12 volt output on the control panel). 6. The D0700 is now ready for testing. System Testing Ensure you have informed your Alarm Receiving Centre that you are ready to test your alarm system. 1. Ensure that the green Status LED is on solidly or flashing. This indicates that power is applied. 2. When the digital data on the ISDN line is detected, the green Status LED should be on solidly. If the green Status LED is flashing then the D0700 cannot detect any digital data on its ISDN connector. This may indicate a fault or it may be the normal situation. Some telephone exchanges remove all digital data on ISDN lines when there is no call in progress. To determine if this is a fault or normal, make a call to any telephone number associated with the ISDN line. If the D0700 detects the call on the ISDN line then the green Status LED will be on solidly. At the end of the call if the green Status LED returns to flashing then the digital data is not permanent and it is the normal situation. If the green Status LED does not go on solid, and there is no response to the call then there is a fault on the ISDN line. Repeat the test by making the equipment that is connected to the D0700 analogue line send a call. If the call is established correctly on the ISDN line then the green Status LED will be on solidly. At the end of the call if the green Status LED returns to flashing then the digital data is not permanent and it is the normal situation. If the green Status LED does not go on solidly and there is no response to the call then there is a fault on the ISDN line. 3. Some ISDN lines are not designed to terminate at more than one unit. Refer to the section on point-to-point ISDN lines on page Make the control panel (or other equipment) that is connected to the analogue line go off-hook to make a call. The red Status LED should be on. Make the control panel (or other equipment) that is connected to the analogue line go on-hook. The red Status LED should be off.

7 ISDN (Integrated System Digital Network) Introduction The digital ISDN is a communication network where the line from the exchange equipment and the service supplied to the subscriber is digital, i.e. not analogue. An ISDN line is a digital telephone line that conforms to the international ISDN standard. It can carry several calls simultaneously. A basic rate ISDN telephone line can carry the equivalent of two simultaneous calls. In the UK, a basic rate ISDN line is called ISDN2 or ISDN2e. Some suppliers call an ISDN2e line Home Highway or Business Highway. See page 8/9. A primary rate ISDN line can carry the equivalent of up to thirty simultaneous calls. In the UK, a primary rate ISDN line is called ISDN30. An ISDN line is always terminated at the user s premises by an NTP (Network Termination Point) which is provided by the Telecomms Service Provider. The NTP is a socket or connection where the user s equipment can be connected. The service supplied to the user from the NTP may vary. The user s digital connection on the NTP is called the S-bus. The S-bus allows many different types of digital communication equipment to be connected, e.g. an ISDN interface card in a PC. An ISDN2 line can be provided as point-to-point or point-to-multipoint. Where there is only one item connected to the S-bus then a point-to-point service is OK. Where two or more items are connected to the S-bus then a point-to-multipoint line must be provided. In many cases, the ISDN NTP operates using power supplied from the exchange equipment via the ISDN telephone line. However some types of NTP may require a connection to the mains supply at the user s premises. Some ISDN NTPs include a converter to provide analogue sockets (e.g. Home Highway). See page 8/9. Where an ISDN2 line is fitted, but an analogue line is required, e.g. for Dualcom, then the D0700 ISDN-analogue converter may be used. The D0700 has some important features especially for security communications including over-ride line grab. Dualcom and other equipment requiring an analogue telephone line cannot be directly connected to a digital telephone line. ISDN2e (Integrated System Digital Network, 2 channel) A basic rate ISDN telephone line can carry the equivalent of two simultaneous calls. In the UK, a basic rate ISDN line is called ISDN2 or ISDN2e. Some suppliers call an ISDN2e line Home Highway or Business Highway. See page 8/9. Where an ISDN2 line is fitted but an analogue line is required, e.g. for Dualcom, then the D0700 ISDN-analogue converter may be used. The D0700 has some important features especially for security communications including over-ride line grab. Dualcom and other equipment requiring an analogue telephone line cannot be directly connected to a digital telephone line. Please note that ISDN lines may be provided by the ISDN Service Provider as point-topoint or as point-to-multipoint A point-to-point ISDN line is normally provided for connection to a PABX telephone exchange in a building. This enables DDI (calling telephone telephone number display) to operate. This type of ISDN line is specifically for connection to only one ISDN terminal device, e.g. a PABX telephone exchange. You cannot connect more than one terminal device on this type of ISDN line. D0700 ISDN Analogue Converter Installation Manual D0700-INST-EN/09G/v1 7

8 ISDN2e (Integrated System Digital Network, 2 channel) (cont d) A point-to-multipoint line is provided for connection to one or more ISDN terminal devices. This is the type of ISDN line normally required by the D0700. Contact your ISDN Service Provider for more information about the type of ISDN line that they can provide. Fig 3 - ISDN2 Home & Business Highway Home Highway, Business Highway Home Highway or Business Highway is the marketing name for a basic rate ISDN2 line supplied by BT with an NTE9 NTP. The NTP provides two S-bus sockets and includes an ISDN-analogue converter and two analogue telephone sockets. This type of NTP can have an analogue telephone, fax, modem etc connected at either or both of the analogue telephone sockets. Dualcom and other equipment that requires an analogue line may be connected to these analogue connectors. See Fig 3. Power for the NTE9 comes from the exchange equipment via the ISDN line and also from the mains supply at the user s premises. In the event of mains failure, the right-hand analogue telephone socket on the NTE9 will cease to operate but all other functions are powered from the exchange equipment. It is important therefore to connect Dualcom and other equipment requiring an analogue telephone line to the left-hand analogue telephone socket on the NTE9. See Fig 3. A maximum of two calls on an NTE9 may be in progress at the same time. Use of one analogue telephone socket constitutes one call. Use of the S-bus on either S-bus socket constitutes one or two calls (64 or 128 K byte bandwidth). If two calls are in progress it is impossible to make another outgoing call or receive another incoming call. D0700 ISDN Analogue Converter Installation Manual D0700-INST-EN/09G/v1 8

9 Home Highway, Business Highway (cont d) The two call maximum means that if either of the S-bus sockets are being used and a telephone call is in progress on one analogue socket, then anybody ringing into the other analogue telephone socket will get a busy signal. Equally any connection to the other analogue socket, e.g. Dualcom and other equipment requiring an analogue telephone line or a telephone at the user s premises, will not hear the dialling tone and will not be able to dial out. Note that an override line grab facility does not exist on an NTE9. ISDN30 (Integrated System Digital Network, 30 channel) A primary rate ISDN line can carry the equivalent of up to thirty simultaneous calls. In the UK, a primary rate ISDN line is called ISDN30. This is a digital telephone line that conforms to the international ISDN standard. It can carry up to 30 simultaneous telephone calls. This type of digital telephone line normally connects directly to a PABX telephone exchange. The D0700 converter cannot be connected to an ISDN30 line. Safety Earth connection Some equipment requires an earth connection to meet the safety requirement of testing and approval. Other equipment designs provide electrical safety with no earth connection. The D0700 does not require an earth connection. Where an E or earth connection is provided at the telephone line terminals of equipment, then this must be connected to an earth point. Ideally, the earth point should be an earth stake in the ground, close to the equipment. Where this is unavailable, then a connection to the mains supply earth should be used. ISDN Line Failure Detection The D0700 regularly checks the digital data on its ISDN connector. These checks incur no call cost. Every 30 seconds the digital path via the ISDN line to the telephone exchange is tested. If the test indicates a line failure the D0700 attempts to re-establish contact with the exchange. If contact cannot be re-established then the test has failed. When two successive tests have failed then the D0700 removes the DC voltage that it puts on its analogue line. This simulates an analogue line failure. Note: Some PABX exchanges with ISDN extensions de-activate the extensions when a call is not in progress. The next test by the D0700 will re-establish contact with the exchange. In this case there will be no line failure condition and the DC voltage will remain on the analogue line. The ISDN line is continuously tested. When the path to the telephone exchange is restored, then the DC voltage will be reapplied to the analogue line. Most security equipment that requires an analogue telephone line also includes a line monitor. This can be set to monitor the DC voltage on its analogue line. This allows the whole telephone line (analogue line, D0700 and the ISDN line) to the telephone exchange to be permanently monitored. Note that this monitoring feature can only be used on ISDN lines that have permanent digital data. See page 4, Testing, item 2. Some line monitors can be set to regularly monitor the telephone line and ensure a dial-tone is available. This feature allows the whole telephone line (analogue line, D0700 and the ISDN line) to the telephone exchange to be regularly monitored even when the digital data is not permanent.

10 ISDN Line Snatch When the control panel (or other equipment) connected to the D0700 analogue line attempts to make a call, e.g. to send an alarm, it is possible that both channels on the ISDN line are busy with calls to other equipment, e.g. a telephone call and a computer internet call. The calls may even be incoming calls that are intended to block the line. Under normal circumstances this would prevent the alarm call being made. The D0700 Line Snatch feature will overcome this situation by forcing all other calls on the ISDN to be cleared allowing the outgoing call to proceed. The Line Snatch feature is always operational. When it is used, the control panel (or other equipment) connected to the D0700 analogue line will have a short delay in receiving the dialling tone. This delay is typically 5 seconds maximum. Call Answering The D0700 is supplied with no MSN selected. In addition, any/all incoming calls on the ISDN line will put a ringing signal on the analogue line. This allows the control panel (or other equipment) connected to the analogue line to answer any incoming call. This response to incoming calls may be made selective or disabled. See Programming below. Programming Programming is stored in an NVM (Non Volatile Memory) in the D0700 and will be retained when the power to the D0700 is removed. To program the D0700: 1. Connect an ordinary analogue telephone to the analogue line. 2. Connect the power supply wires to 12 volts. 3. Press the keys as described below to send programming commands to the D Listen to the handset to hear confirmation beeps from the D0700. Multiple Subscriber Number The MSN (Multiple Subscriber Number) facility on ISDN lines allows different devices at the customer s premises, e.g. telephones, faxes, modems etc..., to have different telephone numbers so that each can be called separately. Contact your ISDN provider for more information about MSN. To make use of the MSN feature for the D0700 analogue line, it is necessary to program the D0700 with a number to uniquely identify its MSN telephone number. 1. Examine the telephone numbers that are allocated to the ISDN2 line. Determine the least number of digits that will uniquely identify each number that is applied to the ISDN line. The MSN numbers are normally sequential, e.g , , , In this example, the number of digits to uniquely identify each telephone number is one, this is the least significant digit, e.g. 0, 1, 2, Determine the number that is to be applied to the D0700 analogue line, e.g Therefore the number to uniquely identify this is Using the programming telephone, press * 9 0 * MSN #. You will hear a confirmation beep. For the example you would press * 9 0 * 6 #. D0700 ISDN Analogue Converter Installation Manual D0700-INST-EN/09G/v1 10

11 Incoming Ringing Response The D0700 can respond to incoming calls or it can ignore them. When the D0700 responds to incoming calls it will put a ringing signal on the analogue line. This allows the control panel (or other equipment) connected to the analogue line to answer any incoming call. When the ringing response is disabled then the D0700 ignores any ringing signal. To disable the response to incoming ringing Using the programming telephone, press * 7 6 * #. You will hear a confirmation beep. To enable the response to incoming ringing Using the programming telephone, press * 7 6 * 1 #. You will hear a confirmation beep.
