AP32 is an easy-to-use multipurpose test telephone for telecom technicians. It has been designed in co-operation with users to meet their practical daily work requirements.

With AP32, the user does not need to carry several individual devices. Yet AP32 is compact and inexpensive. To switch AP32 from telephone to line monitor mode, or from DSL tester to signal generator mode, just use the simple keypad shortcuts. The LCD display shows active mode and essential settings all the time with its large characters and informative symbols.
CI (communication identification) mode is the basic test mode for monitoring lines without causing interference. It shows the line voltage and possible frequency clearly on LCD and helps the technician to define which type of line is at hand, such as POTS, ISDN, or xDSL.
DSL pair identification
The DSL test mode is an extended monitor mode for checking especially DSL lines. Besides showing voltage and frequency, DSL test makes high frequencies audible, which helps the user to recognize active DSL lines or, for example, to tell whether a DSL modem is sending a handshake signal.
AP32 also includes an unbeatably fast DSLAM test: just press OK during DSL test and AP32 will tell within a few seconds whether there is an ADSL or VDSL DSLAM on line or not. No more waiting with a laptop and modem! In telephone modes AP32 uses an integrated ADSL/DSL filter to minimize interference to DSL lines.
Calling over a POTS line with the AP32 is as easy as using a mobile phone: Choose a name from the phone book, redial a number from the redial list, or manually dial a number and press off-hook. If the AP32 is off, it will wake up to an incoming call and give a ring tone. Furthermore it will tell the caller ID number with DTMF or FSK protocols.
LB Field phone
AP32 works as a field phone as well. Using the LB-mode over a cold pair is very easy: just connect, press off-hook and start talking. You can even use DTMF tones in LB-mode for testing or programming certain equipment.
Monitoring security equipment messaging
AP32 also supports monitoring of the security messaging protocols widely used in the security & alarm systems. Supported protocols include SIA® standardized 300 bd FSK ("SIA"), Ademco® Contact ID, most common pulse formats and generic DTMF of telephone dialling. AP32 can monitor and display both the transmitted messages & data and the received handshakes and acknowledgement signals.
There are even more handy features in the AP32 to ease your work, for example...
Check line status - See the line voltage before a call and check that the loop current is within limits during a call.
Pair tester - Test the approx. resistance of a pair to find out if the pair is open, shorted or low-ohmic.
Monitor dialing - In CI mode monitor all DTMF codes sent by a terminal equipment, such as telephone dialing sequence.
Signal generator - Use the AP32 as a signal generator to produce specified frequency between 0.1kHz and 99.9kHz on three alternative levels.
AP32's new firmware supports monitoring of the security messaging protocols widely used in the security & alarm systems. When AP32 is connected parallel with the telephone line of an alarm equipment, it can monitor and display the transmitted messages data as well as the received handshakes and acknowledgement signals. AP32 does not take part in the messaging nor does it interfere with it.
Supported protocols include SIA® standardized 300 bd FSK ("SIA"), Ademco® Contact ID, most common pulse formats and generic DTMF of telephone dialling. Active format can be chosen using the menus.
SIA format (300 bd FSK)
In the example below there is an SIA message transmitted by an alarm device. <OK> tells that the message is formally correct. In case of an interrupted message a <BREAK> message will be displayed and in case of a parity error, AP32 will display <ERROR>. Browsing to screen 2/3 displays the account ID code of the alarm device and the area ID by which the alarm was caused. Screen 3/3 shows that the cause was burglar alarm in zone 01.
Pulse formats are mostly used with older alarm devices and central stations. AP32 supports their most common pulse speeds from 10 to 40 characters per second. Below there is an example of a pulse coded alarm message triggered by tamper sensor.
AP32 can also monitor handshake signals transmitted by a central station. Below example shows that AP32 has detected a handshake or kiss-off signal on 1400 Hz frequency (2300 Hz signals are also supported)
This example shows a formally correct Contact ID message from a device with ID 4502. Cause is again burglar alarm. The message can be browsed back and forth just like an SIA message.
Some alarm equipment and many others use generic DTMF for messaging through the telecom network. AP32 displays these number coded messages just like telephone dialling, hence numbers are also aligned to the right, as seen in the example below.

LSA/BNpk adapter connects a test equipment with 4mm banana plugs to Krone LSA Plus terminals by breaking (disconnecting) the pair. The adapter plug has a fabric reinforced rubber strap. With the strap the adapter can be hung e.g. to a test telephone connecting cord. This way the adapter is always at hand and the strap tightening mechanism prevents the adapter getting lost.
