Table 2. TS25D Test Set Icons (Cont’d)IconsLine Voltageand CurrentMeasurementDescriptionThe TS25D measures the voltageacross Tip and Ring when the testset is on-hook. It displays the Voltagewith the V icon in the upper righthandcorner of the LCD screen. Thetest set measures the current it drawsfrom the line when off-hook anddisplays the result with the mA icon inthe upper right-hand corner of theLCD screen.Voltmeter Range: 0 - 250 VdcCurrent Meter Range: 0 - 120 mAsignaling if present. The test set draws no directcurrent from the line and it transmits no signalsto the line. Also, in Monitor mode, the TS25Dmonitors for high-speed data signals on the line.If the test set detects data it will display DATADETECTED on the LCD. If there is no highspeeddata on the line, the LCD will display NODATA.In the Monitor mode, the test set is typicallyused to perform one or more of the followingprocedures:■Verification that a line is idle when lookingfor a line to borrow.OPERATIONThe test set has two basic modes of operation:Talk mode and Monitor mode.■■■Listening for noise on the line.Performing a test for the presence of highfrequency data on the line.Measuring the DC voltage from Tip to Ring.CAUTION:When testing circuits which are close toa battery source, the pops in the handsetreceiver that result from clipping onto aline may be quite loud. Although there isprotection against acoustic shock builtinto the test set, if the receiver is heldtightly against the ear, acoustical shockmay occur.Monitor ModeMonitor mode primarily is for audio monitoringof the Tip and Ring pair while on hook. InMonitor mode, the test set has a high inputimpedance, which allows monitoring of the linewithout disrupting conversations or data■■Detecting DTMF signals.Monitoring line polarity.The TS25D will respond to incoming ringingsignals when it is in Monitor mode. It does notdetect ringing signals when it is off.Talk ModeWhen the TS25D is connected to a workinganalog telephone line and is switched to Talkmode, the test set will go off-hook and draw dialtone. An off-hook TS25D works like a standardtelephone. When off-hook, the TS25D is usedto perform its main purpose, which is to verifythe proper operation of analog voice telephonelines or to establish temporary communicationson a “borrowed” pair.TS25D Test Set 5

In both Talk and Monitor mode you can changethe receiver’s volume level by pressing the Upor Down arrow keys.Each time the TS25D is switched to Talk mode,it quickly tests the line for high-speed data andfor DC voltage before it goes off-hook. If thereis no high-speed data on the line, and there isenough DC voltage to go off-hook on (>3V), thetest set will go off-hook without you evernoticing that the tests have been performed.Occasionally you may run into the situationwhere you have accidentally connected to aline carrying high-speed data or where youhave connected to a line with either too little ortoo much DC voltage to go off-hook on. Thedata and voltage tests are designed to detectthese conditions and are discussed in thefollowing sections.Data LockoutWhen the TS25D is switched to Talk mode, ittests the line for high-speed data signals andfor DC voltage before it goes off-hook. If data isdetected in the frequency band from 20kHz toabout 1 MHz, the test set will refuse to go offhookand the LCD will display DATADETECTED, DOWN ARROW TO OVERRIDE.This mode is called Data Lockout mode. In theData Lockout mode, the test set is kept onhook,“locked out”, despite having beenswitched to Talk Mode. Data Lockout Mode isprovided to prevent accidental corruption ofdata transmissions while working in moderntelecommunications cable environments thathave a mix of analog telephone and dataservices. There is often no way to know byinspection or by audio monitoring if the wirepair you are connecting to is a high-speed dataline or not. Most high speed data is above thehuman hearing range so listening to the line inMonitor mode may not allow you to identify it asa data line. If you see the DATA DETECTEDmessage, chances are you have accidentallyconnected to a data line. If so, disconnect thetest set from the line, being careful not to shortthe clip leads together in the process. If youhave accidentally connected to a data line, donot press the DOWN ARROW TO OVERRIDEbecause “overriding” will cause the test set togo off-hook and take the data service down. Insome situations you may want to go off-hook.The next section covers this.Data Lockout OverrideCAUTION:Shorting the Tip and Ring leads togetherwhile connected to a data line will causedisruption to the data.Whenever you try to go off-hook on a highspeeddata line, the TS25D Test Set will go intoData Lockout mode and will refuse to go offhook.This is to protect data services, most ofwhich would be corrupted by loading the linewith the low impedance of an off-hook6 TS25D Test Set

telephone. But ADSL (Asymmetrical DigitalSubscriber Line) is a different circumstance.ADSL is a high-speed data service intentionallydesigned to co-exist on the same wire pair asstandard analog telephone service. If you try togo off-hook on a wire pair carrying both ADSLand analog telephone service, the TS25D TestSet will detect the ADSL data signal and go intoData Lockout mode as it would on any data line.You will see the message DATA DETECTED,DOWN ARROW TO OVERRIDE. Now, if youwant to go off-hook to access the analog phoneservice sharing the line with ADSL, press thedown arrow as instructed on the LCD. TheTS25D will override the lockout, will go off-hookand draw dial tone without disturbing the coexistingADSL service. The TS25D Test Set hascircuitry that protects the ADSL service when itis off-hook. Going off-hook on ADSL lines is themost common use of Lockout Override.There is another case where the overridefunction may be needed. You may encounterthe rare circumstance where the analogtelephone line you connect to is not carryingany data but there is enough high frequencynoise on the line that theTS25D Test Set thinksthere is high-speed data on the line. If you knowyou are connected to such a line, use theLockout Override function to go off-hook. Thisusually only happens when the telephone line isnear a commercial AM radio broadcastantenna.There is a provision for turning the data lockoutfunction off. When Data Lockout is turned off,the test set will go off hook on a powered linewhen switched to Talk (T), even if data ispresent. Whe Data Lockout is off, the test setwill still detect data in Monitor mode. To learnhow to turn Data Lockout on and off, refer to theSystem Configuration section.High Voltage LockoutCAUTION:Do not short the test set leads to eachother while it is connected to a linecarrying high voltage.The TS25D Test Set is designed for use inenvironments where analog voice lines co-existwith lines that carry high DC voltages. When theTS25D Test Set is switched to Talk mode, ittests the line for high-speed data and itmeasures the DC voltage on the line before itgoes off-hook. If the DC voltage exceeds 140 V,the TS25D Test Set will prevent itself from goingoff-hook and will display HIGH VOLTAGELOCKOUT. Going off-hook on a line carrying ahigh DC voltage can damage the power supplyfeeding the line. The test set will prevent thisfrom occurring. Unlike the data lockout, there isno provision for the operator to override a highvoltage lockout. Lines with voltages exceeding140 Volts DC do not carry analog voiceservices. If you encounter a high voltagelockout, switch the Talk/Monitor switch back toMonitor (M) and carefully remove the test leadsfrom the line.TS25D Test Set 7

Low Voltage LockoutEach time the TS25D Test Set is switched toTalk mode, it tests the line for high-speed datasignals and it measures the DC voltage on theline before it goes off-hook. If there is less than3 Volts on the line, there is not enough voltagefor the test set to go off-hook and the LCD willdisplay LOW VOLT LOCKOUT, DOWNARROW FOR TALK BATTERY. The LowVoltage Lockout message is an indication thatthere is very little or no voltage on thetelephone line — not enough voltage for thetest set to perform off-hook operations. Themost common cause of this message is whenthe test set is switched to Talk mode and it iseither not connected to anything or it isconnected to an un-powered pair of wires (dryloop). In this state you have the option ofactivating the TS25D Test Set’s Talk Batteryfunction.There is one additional line condition thatshould be mentioned. When the test set,connected to a line carrying data signals but noDC voltage, is switched to Talk mode, the LCDwill display DATA DETECTED AND LOW VOLTLOCKOUT. Some data services have noassociated DC voltage. The low impedance ofthe TS25D Test Set’s off-hook state wouldcorrupt these types of services. Thus the testset does not have any provision to override thelockout when this line condition is encountered.In any of the test set’s lockout states, removingthe test set from the line condition that iscausing the lockout automatically clears thelockout condition.Talk BatteryThe TS25D Test Set has the ability to power adry telephone wire pair to enable voicecommunications between itself and anothertest telephone connected to the other end ofthe pair. After turning on Talk Battery at yourend, the person at the other end should takehis test set off-hook. If the test set at the otherend has talk battery capability, it should not beenabled.The Talk Battery function provides:■■Communications capability on 26 gaugewire pairs up to about 1000 feet, longer onlarger gauges.A continuity test.When Talk Battery is active, the LCD displaysLINE = SHORTED if the test set is connectedto a short circuit of 0 ohms to about 100 ohms.To enable Talk Battery:1. Connect the test set to a dry pair.2. Switch the test set to the Talk (T) position.3. Press the down arrow when the messageLOW VOLT LOCKOUT, DOWN ARROWFOR TALK BATTERY appears.Note: The Talk Battery function will use up your 9Vbattery more quickly than other TS25D functions.8 TS25D Test Set

Caller ID/Call Waiting IDThe TS25D Test Set will detect and display bothon-hook and off-hook caller ID messages. Thisis useful for verifying that a customer’s Caller IDservice is working properly. Caller ID (CID)messages are received when the receivingtelephone is on-hook. Call Waiting ID (CIDCW)messages are received when the receivingtelephone has already established a call to asecond party and a third party places a call toyour line.To perform Caller ID detection:1. Connect the test set to Tip and Ring of thecustomer’s phone line. Either remove thecustomer’s phone from the line or leave iton-hook.2. Switch the test set to the Monitor (M)position. If there is another line in thebuilding, call from that line to the line thetest set is connected to, or arrange forsomeone to call the line the TS25D Test Setis connected to. When the call comes in,you will hear the first ring, and then thereceived Caller ID message will bedisplayed on the test set’s LCD.Performing Call Waiting ID is a little morecomplicated:1. Connect the test set to Tip and Ring of thecustomer’s phone line. Either remove thecustomer’s phone from the line or leave iton-hook.2. Switch the test set to the Talk (T) positionand establish a voice call to a second party.If there is another line in the building, callfrom that line to the line the TS25D Test Setis connected to, or arrange for someone tocall the line the test set is connected to.When the call comes in, you will hear theCall Waiting Alert tone. This will be followedby the CAS tone and the Caller IDmessage. When the Caller ID message isreceived by the test set it will be displayedon the LCD.If the received Caller ID message has errors,the TS25D Test Set will display LINE ERROR.TonerThe Toner function is useful when tracing therouting of a pair of wires. When the Toner isactivated, the TS25D Test Set generates a toneonto the wire pair the test set is connected to.The routing of the wire pair can then be tracedby using an inductive Tone Probe to pick up thetone.To use the Toner:1. Connect the test set to the pair of wires youwant to trace.2. Switch the test set to the Monitor (M)position.3. Press the SEL button once to activate thetest set’s menu.4. Use the Down arrow key to scroll the cursordown to the TONER entry.5. Press the SEL key. The Toner will beactivated and the LCD will display TONERACTIVE.To turn off the Toner press the BACK key.TS25D Test Set 9

If you accidentally connect to a data line, whenyou try to turn on the Toner you will get amessage DATA DETECTED TONER NOTAVAILABLE. Remove the test set from the line.The Toner on the test set is intended for use ondry (un-powered) pairs of wire. Before turningon the Toner, verify that the wire pair you areconnected to is not carrying DC voltage bychecking the test set’s voltmeter in the upperright corner of the LCD. The Toner is onlyavailable when the TS25D Test Set is inMonitor mode.DTMF DetectionThe TS25D Test Set allows the user to captureDTMF tones generated on a telephone line bytelephones, fax machines, modems or anyother DTMF generating device. This feature isuseful when you suspect the customer’stelephone equipment is not generating properDTMF signals.1. Connect the TS25D to Tip and Ring of theline under test.2. Switch the test set to the Monitor (M)position.3. Put the customer’s telephone in tonedialing mode and take it off-hook.4. Dial a number on the customer’s phone.The number dialed will be detected anddisplayed on the test set’s LCD.5. Verify that the number on the LCD is thesame as the number you dialed.The TS25D Test Set will detect and display theDTMF tones for 0-9, ❋, #, A-D.To clear the LCD screen, switch the test set Off,and then back to Monitor mode. DTMFdetection is only available when the TS25DTest Set is in Monitor mode.Using Your Test SetNote: Remove the protective film that covers the LCDdisplay before using your test set.Originating a CallTo originate a call:1. Clip the test set to Tip and Ring of apowered subscriber loop.2. Switch the test set to the Monitor (M)position and listen to the line to verify it isidle.3. If not idle, disconnect the test set from theline.4. If the line appears to be idle, switch the testset to the Talk (T) positions.5. If no data is detected, the test set will go offhook.6. If high-speed data is detected, the test setwill not go off hook (will lockout) and willdisplay DATA DETECTED, DOWN ARROWTO OVERRIDE, indicating the presence ofdata. Try another line or you can overridethe data lockout (see Data LockoutOverride).7. The numeric keypad, LNR key, or memorydialing may be used to dial a number fororiginating a call.To disconnect a call, switch the test set off, or tomonitor, or remove the clip leads from the line.10 TS25D Test Set

Answering a CallTo answer an incoming call:1. Place the test set in Monitor mode torespond to incoming ringing signals.2. If a ringing signal is received, switch the testset to the Talk (T) position. The test setautomatically tests for high-speed data onthe line.3. If no data is detected, the test set will go offhook.4. If data is detected, test set will lock out anddisplay the message DATA DETECTED,DOWN ARROW TO OVER-RIDE.5. To go off hook with data present you canoverride the data lockout (see Data LockoutOverride).To disconnect a call, switch the test set off, or tomonitor, or remove the clip leads from the line.Last Number RedialIf a call is not successful and you wish to redialthe same number, do the following:1. Switch the test set off, then move the slideswitch to the Talk (T) position.2. After the test set goes off-hook press theLNR key. The last number dialed will beautomatically redialed.The last number redial function is available ineither the Pulse or Tone Mode. The method ofdialing is not stored with the number. The redialmemory has a 23-digit capacity.In Tone Dialing mode, the dialing keys that arepermitted to be stored in LNR memory include1,2,3,4,5,6, 7,8,9,0,❋, and #. If the star (❋) andpound (#) keys are pressed in pulse mode theywill be ignored.Memory DialingThe TS25D Test Set allows the user to dial preprogrammednumbers in either Tone or Pulsemode.
