3m 965dsp manualThis document will give you a brief overview of the products, a description of their test functions, and some technical hints on how to find problems on telecommunications cables. For Technical Service, Warranty or Repair questions call: 800 426 8688 in the US or Canada, or contact your local 3M Representative. Communication Markets Division 3M Telecommunications 6801 River Place Blvd. The screen format is similar to the following for most functions. Test Leads The Test Lead icons are shown on each of the measurement screens. The active control keys for each function are shown at the bottom of the corresponding 965DSP screen.The blue keys become number or letter keys when editing.It shows the model name, installed options, serial number, copyright year, software version, and the selected country. The battery symbol in the upper right-hand corner of the display gives an indication of the approximate battery capacity. Selecting a new country will configure the 965DSP with the setups for language, units, clock format, wire gauges, and cable types for that particular country.Distance: Feet or Meters. This affects all distances displayed in the 965DSP. This affects the TDR “velocity of propagation.” Use “Vp” in the US and Canada.Use the blue keys to enter the values. The limits indicate the values at which the measurement result passes (OK), is marginal (Yield Sign) or is unacceptable (Stop Sign). After a period of inactivity equal to the default period, the unit will beep, then automatically power down. User Info This selection allows you to add optional additional information to your saved records.Once the User Info option has been changed, the changes remain in effect until you explicitly change them again.The highlighted reading is “live” and the non-highlighted readings are the last values.Connect the red and black leads to the pair to measure loop current.The “V” in the upper right corner of the screen indicates that the resistance measurement compensates for C.O.http://gorod-tvoy.ru/data/3m-overhead-projector-manual.xml

Connect the red and black leads to an inactive pair. Connect green to shield or ground. Calibrate the 965DSP at the same temperature at which it will be used. Note: Initiate a self-calibration prior to the very first use of your 965DSP. The distance measurement requires that you specify the wire gauge of the pair. This is done in the Load Setup screen.Connect the red and black leads to the selected pair. Connect green to shield or ground.If no results have been stored, “No Results Stored” will be visible on the screen. If one or more test results have been stored, the ID number for each will be displayed. The printer should be configured for 9600 baud, 8 data bits, 1 stop bit, no parity. If no ADSL Modem test results have been stored, “No Results Stored”. Certain result boxes may be blank if the information is not available.Preseize Time (B) - The measured time period between the first Ring Burst and Channel Seizure. Twist - The ratio of the received Mark and Space signal levels. Seizure Bits - The number of bits received during the Channel Seizure (C) period. Connect the red lead to one side of the pair. Connect the green lead to the other side of the pair. Connect the red lead to Ring of the active pair. Connect the black lead to Tip. Connect the green lead to Ground. You may choose to use a “far-end switch” to open and close the far-end. The 3M KM Box Model 1162 is recommended for this application. The 965DSP will automatically send tones on the blue and yellow leads to communicate with the 3M KM Box (far-end switch). If you are using a far-end switch (3M KM Test Switch Model 1162) to open and close the far-end, you should also connect the blue and yellow leads to the pair under test. This value is used by some companies as part of the K-Test measurement. The 965DSP displays the open and closed fault ratios.http://xn--80aamdqpfpr.xn--p1ai/upload_picture/3m-overhead-projector-9200-manual.xml If the size of faults is reversed, you will see the following screen: K-Test Error This screen indicates that the connections to the red and green leads are reversed and the leads should be. Start Connect the red and green leads to the pair. Connect the strap at the far-end across the pair.If other pairs are not active, short at least 30 of the inactive pairs to the cable shield. The TDR function should be used to determine distance to a “partial”. Edit Custom Use this function to change the value of the “Custom Cable” type. Select Custom Cable if you are using a specific type of special cable on a regular basis. Note that there are ten tones.No tone is heard in the speaker for the High Frequency Tone. Note: The volume control does not affect the level of the tone sent on the pair. There are two possible hookups: Separate Pair or Single Pair. Separate Pair (This is the preferred hookup) You must first use the Resistance function to determine the faulted conductor and identify a separate good pair (a pair with no faults). Connect the black Lead to the reference. (The reference is the return path for the fault and can be the shield or another wire in the cable.) Connect the green and yellow test leads to the separate good pair. The wire gauge, temperature and section number are displayed above the bottom bar. If the Yield Sign shows beside the results, this indicates a possible marginal result (due to noise or other line conditions). Use the Separate Pair hookup for all cases in which a separate pair is available; it is always the preferred method. The results at the top of the screen indicate the “Distance to Strap”. The results on the second line indicate the “Distance to Fault”. The screen will show the combination of errors that have been detected. If you choose Temperature or Length, enter the new value using the blue numeric keys. One cable parameter (a section length or temperature) should be left as unknown.http://www.drupalitalia.org/node/66958 If a value is entered for all parameters, temperature will be treated as an unknown and will be calculated by the 965DSP. In this case the screen will show the calculated Distance to Strap (the sum of all sections) in the main result box and the “Distance to Fault”on the left on the next line and the “Distance Strap to Fault”. In this case the screen will show the entered Distance to Strap (or the sum of all sections) in the main result box, and will show the calculated temperature at the bottom. The screen also shows the number of the faulted section at the lower right side of the screen. The multi-section screen will now show the computed length of the unknown section. RFL Errors One of several errors may occur during an RFL multi-section measurement. Note: All 965DSP Series Loop Analyzers are equipped with the ISDN Datalink function;. The 965DSP displays the word “Connecting” while the instrument goes through three steps: 1) AIP (Activation in Progress), 2) Sync (Synchronization), and 3) Link (successful connection). If any of these three tests is unsuccessful, the words “Link Failed”. Note: This function is suppressed in countries where ISDN interoperability with the 965DSP Block Error Test has not been verified. The 965DSP will count and display the number of near-end and far-end errors. Use the ADSL modem feature to establish a link with a DSL Access Multiplexer (DSLAM) in the central office or remote cabinet and determine the ADSL data rate that the pair will support. Select Captured Test to set up a link, measure the line performance, and drop the line automatically to save battery life. Contact 3M Technical Service for assistance. Status messages about the connection process are displayed as they occur. The hourglass indicator at the bottom of the screen is displayed as the connection process proceeds. Connection states include: Starting: The ADSL modem in the 965DSP is. Only the achieved Upstream and Downstream line rates and capacity values are shown.http://aeviladeste.com/images/3m-965ams-manual.pdf The pair PASSED if the line rates were greater than or equal to the threshold rates and the capacity values were less than or equal to the threshold capacities. FAST: Achieved line rate in kilobits per second on the Fast channel. INTR: Achieved line rate in kilobits per second on the Interleaved channel. Note: FAST or INTR will display with the achieved line rate to indicate the selected channel type. FEC, CRC, and HEC counts in each direction are also displayed. LOS indicates a Loss of Signal alarm. This means that the ADSL received pilot tone power was 6dB or more below its reference power. Pilot tones do not carry data and are used for line synchronization. LOF indicates a Loss of Frame alarm. ADSL modems require wide bandwidth to operate since they essentially use 256 separate simultaneous modems, each requiring about 4kHz of bandwidth called a bin. Use the blue keys to enter an alphanumeric ID. The ID may have up to fourteen characters. Up to 14 alphanumeric characters can be entered in each field. The data entered into each field will remain present for every saved result until explicitly changed or cleared. In the unlikely case that the warning message shown above appears, simply exit the ADSL Modem application for a few minutes to allow the modem to cool down. Contact 3M Technical Service for any undefined codes.Common error conditions and their causes are listed in the table below. Contact 3M Technical Service for any undefined codes. Numeric Meaning Code. The screen displays the signal level in dBm, the frequency of the tone in kHz, the selected service type, and the line terminating impedance. Connect the red and black test leads to the pair.The spectrum analyzer continuously analyzes the line and updates the screen as conditions change. The screen displays the average power of all signals and noise in the selected frequency span in dBm at the upper left. Extend the test leads away from the 965DSP when conducting DSL tests, and make sure that the red and black leads are kept as close together as possible to minimize RF noise pickup. TDR measures distance to events based on input about the pair. TDR Setup TDR features a setup function that allows you to enter the cable type, gauge and first length. Vp is then automatically set from these selections. Single Trace is used to view a single pair at a time. Dual Trace Connect the red and black test leads to the pair under test. Connect the blue and yellow test leads to the reference pair. The reference pair is displayed at the bottom of the screen. Any changes in the control parameters affect both traces. It is not possible to control each trace independently. Dual Trace is used to compare two pairs at the same time (usually a faulted and a good pair). Memory mode is used to compare a pair under test to a stored trace in memory. The first screen in memory mode will show a list of the ID numbers for all stored TDR traces. This mode continuously detects and displays the maximum and minimum traces that occur from the time that the mode is first selected. As a new maximum or minimum trace is detected, it will replace the previous one on the display. The 965DSP displays the controls and other parameters at the bottom of the screen.Gain allows you to select the vertical gain of the TDR. Higher gain will make events look taller on the screen and is helpful for finding small faults. This is demonstrated below. The first screen shows the TDR trace before vertical offset. The next screen shows the TDR trace after offset. The vertical offset function affects all modes except Memory. The distance to the cursor includes the five foot length of the test leads. Use the blue keys to enter an alphanumeric ID. The ID may have up to fourteen characters. Up to 14 alphanumeric characters can be entered in each field. The data entered into each field will remain present for every saved result until explicitly changed or cleared. For Loss, Noise and Longitudinal Balance, you will first be asked to dial a number (for a quiet line, milliwatt line, etc.) before starting the test. You must use a separate instrument to generate the tone at the far-end.The 965DSP automatically goes off-hook to measure Longitudinal Balance.This test can be used to analyze a pair for loading and bridge tap problems. The result is displayed on a graph with relative impedance level displayed on the y-axis (in dB) and the frequency on the x-axis. The Wideband Autotest requires the use of a Far-end Device (FED) such as a 3M FED, FED II, or CTC Smart Strap.The Active Pair results screen will appear. This can be used to identify the pair at the other end. If an ID tone is not needed, the 3M FED can be left off since it will be remotely powered up during the Autotest. A Wideband Module Model C1110W is required for Wideband Autotest. At the far end of the cable, connect the Control Pair (Pair 0) T and R terminals to the separate control pair in the cable. Inactive setup with 3M FED selected. When this part of the Autotest is reached, the user will be requested to swap the black and green test leads or to skip this test. If this test fails, the following warning screen will appear. The 965DSP performs a second test to determine if the user’s choice of a FED II is correct. If a FED is found instead of a FED II, this screen will appear. Check the test lead hookup for the 965DSP and the FED. The Autotest can be run with the FED connected directly to the 965DSP to determine if the cable hookup is causing the problem. Balance Load Coil Inactive Pair Tests without FED Ohms Opens Long. Balance Voiceband Scope Single Tone Loss Loop Resistance Load Coil Inactive Pair Tests with FED. The 965DSP will display the Save Results screen as follows: The date and time display the 965DSP “system clock.”. To change the character, press the key of the new character once (for a number) or several times (for a letter). Connect the red and black leads to the pair for lines using Loop Start. Also connect the green lead to ground on Ground Start lines. Typical life of the battery pack is two years. To change the battery pack: 1) Loosen the six screws on the battery compartment door and remove the door. 2) Remove the old pack. Plug the AC cord into the AC charger and into a power outlet. Plug the DC cord into the 965DSP. Make sure that the key on the plug fits properly into the slot in the connector. Replacement Items You may order any of the following replacement items from 3M.

Subscriber Loop Analyzer 965DSP The 965DSP analyzer is a microprocessor-controlled integrated test set that provides fullfeatured POTS, wideband and DSL-specific testing. The functions include fault location and repair verification on twisted-pair and drop cables (utilizing capacitance bridge, resistance bridge and Time Domain Reflectometer (TDR) functions). The 965DSP analyzer executes a wide range of individual tests, or performs automatic test routines to categorize and sectionalize problems. The hand-held set is housed in a lightweight, ergonomically designed case for portability and ease of handling. The spectrum analyzer test function enables the operator to view the DSL frequency spectrum and identify spectral interferers such as crosstalk noise generated by other services. It delivers all the multi-function capabilities of the 965DSP tester plus the testing functions of the ADSL modem. Extended loss measurement ranges, spectrum analyzer and E, F and G filtered wideband noise measurements complete this comprehensive family of rugged loop testers. The units are weather resistant and weigh only three pounds (4.5 lbs. with test leads and soft case). Preserving the rugged dependability of all Dynatel products, the ADSL option incorporates a durable “spacer” element to the current 965DSP molded plastic case to permit easy and robust expansion of the ADSL circuit board. Far End Device II Designed to provide remote controlled far end testing assistance during subscriber loop testing, the far end device II is a companion to the Dynatel 965DSP family of subscriber loop analyzers where the “one person out” concept has been implemented. The tester performs a wide range of voice band tests to analyze problems on twisted-pair cables. Weather-resistant and weighing only 1 pound, the hand-held 945DSP test set is housed in a lightweight case for portability and ease of handling. For charging only. Do not operate when using charger. Built to ISO9001 certification for manufacturing facilities. Built to Bellcore (Telcordia Technologies) TSY000078 manufacturing methods. Meets UL50 Rain Test. ADSL datalink capability is limited to link synchronization. Modem will initiate a connection with the far-end under operator command. Status messages indicating link progress will be returned.FUNCTION DESCRIPTION Voltage (V) Detects and measures the presence of central office or foreign DC and AC voltages on R-T, R-G and T-G. Current (mA) Measures DC loop current. Ground resistance When measuring mA, press the set up key to measure and display the ground path resistance (when supported by the switch). Resistance test Measures conductor and insulation resistance up to 30 megohms. Accurate readings in the presence of foreign voltage. Full autoranging. Insulation soak test Monitors the leakage resistance from the test leads to ground and indicates changes in the insulation resistance over time in the presence of high voltage. Increasing resistance is an indication of a wet fault and decreasing resistance is an indication of oxidation, which is breaking down and becoming more conductive. Opens Measures the open length of tip, ring or cable pair at distances up to 100,000 ft, (30 km). Tone Provides 577 Hz ID tone for conductor identification, and 404, 1004 and 2804 Hz precision tones for determining circuit loss. Loss Measures voiceband loss up to 5KHz, displaying frequency and level. Noise Measures circuit noise and power influence, and displays calculated balance. C-Message Weighting is used in the U.S. and Canada, and a Psophometric Filter where ITU (CCITT) Standards are used. Longitudinal balance This test provides active measurement of line balance. Dial key Allows storage of 10-14 digit numbers for testing of active lines. Load coils Counts up to 5 load coils on an unterminated pair. Result summary screen This screen shows the results from last V, mA, Ground Resistance, Ohms, Opens, Load Coil Count, Noise, PI, LB and Loss test in a tabular form for easy analysis. If desired, these results can then be saved to one of 10 result storage locations. Result storage Storage will be provided for 10 sets of results.
