3 CO MDF or X-Connect Box Pair ID Hookup & Procedure SCAN Mode Front ap Shoe Pair to be identified - also serves as a communication link between the CO & Field unit. here must be continuity to at least one of the conductors. Bridge CO Unit Note: he SCAN Mode can be used to identify both active and inactive pairs CO Unit ed to -48 to 52VDC CO Battery (eference Voltage) Note: It is possible not to connect the ED clip to the CO battery, the system should work normally. Only in this case, the reference voltage of -48VDC will be provided internally. Procedure: Very important: Cable Shield/ serves as the communication return path for both the CO and Field units. he cable shield must have continuity (no opens) from the CO to the field. If the cable shield is open use a any known good pair within the 100-pair group under test, instead. 1. With the Field unit ON and the GOUND clip connected to the cable shield, connect the BIDGE clip to any pair you wish to identify within the 100-pair group under test, then press the SCAN key. he pair number, color code and status of the pair will then be displayed on the screen. he LCD elements for the particular pair will also light up on the screen. 2. If SPECIAL(any service other than POS) or UNBAL (unbalanced which means one side of the pair is grounded) is detected, the unit will pause. his is to allow the operator to decide if he wants to go ahead and identify the special or unbalanced circuit or just leave it alone. o force the unit to identify the pair, press the SCAN key twice. See examples on the following pages. 3

4 SCAN Mode Display Examples SPAE WHIE SLAE SCAN Fig. 1: NOMAL SCAN Mode Display Connect the Bridge to any pair and press SCAN key. Pair #5 is identified as shown by the numeric display at bottom right-hand corner of the LCD screen and the corresponding LB elements also light up. he color code of the pair (WHIE/SLAE) is also displayed. Bridge APICS 3322 or SPAE CHK CLIP OPEN FAUL SCAN Fig. 2: OPEN (one conductor only) Connect the Bridge to any pair and press the SCAN key. he unit emits a HI-LO tone which indicates a condition that is not normal. he pair is identified to be Pair #13 with an OPEN fault. A single lighted LB element also confirms the OPEN. 4

5 SCAN Mode Display Examples SEND E SCAN Fig. 3: OPEN (both conductors) Connect the Bridge to any pair and press SCAN key. he unit emits 3 successive LO tones which means no communication link has been established between the CO and Field units. A SEND E(or) message is also displayed. In this situation, the pair cannot be identified. he OPEN fault must be cleared first before pair ID can be achieved. Bridge APICS 3322 or 3122 SHO SPAE FAUL SCAN Fig. 4: SHO Connect the Bridge to any pair and press the SCAN key. A HI-LO tone is emitted which indicates an abnormal condition. he pair is identified to be Pair #37 with a fault, a SHO. 5

6 SCAN Mode Display Examples SPAE EVESE ED GEEN SCAN Fig. 5: EVESE Connect the Bridge to any pair and press SCAN key. A HI-LO tone is emitted which indicates an abnormal condition (conductors EVESED). he pair is identified to be Pair #8. Bridge APICS 3322 or 3122 SPAE COSS FAUL Fig. 6: COSS SCAN Connect the Bridge to any pair and press the SCAN key. A HI-LO tone is emitted which indicates an abnormal condition. Pair #22 is identified and is crossed (fault) to pair #25 as indicated by the LB elements. 6

7 SCAN Mode Display Examples SPAE SPLI FAUL SCAN Fig. 7: SPLI Connect the Bridge to any pair and press SCAN key. A HI-LO tone is emitted which indicates an abnormal condition. he pair is identified to be Pair #15 and is SPLI to Pair #12 as indicated by the lighted LB elements. Bridge APICS 3322 or 3122 WOKING WHIE BOWN SCAN Fig. 8: WOKING (active, non-busy) Connect the Bridge to any pair and press the SCAN key. A single HI tone is emitted indicating a normal condition. he pair is identified to be Pair #4 and its color code (WHIE/BOWN) is also displayed. 7

8 SCAN Mode Display Examples Bridge APICS 3322 or 3122 UNBAL SCAN SPAE Fig. 9: GOUND Connect the Bridge to any pair and press SCAN key. he unit emits single LO tone, displays an UNBAL(anced) condition of the pair and then goes into a pause to allow the operator to further investigate the pair. he UNBAL(anced) condition means that one side of the pair is grounded and it can either be a normal characteristic to the pair or it can be a fault. Note: he GOUND can be verified by using the LB mode and to force the unit to identify pair, follow instructions in Fig. 9a. FAUL SCAN Fig. 9a: GOUND Press the SCAN key, twice. A successive HI-LO-HI tone is emitted indicating a possible fault condition. Pair #45 is identified but then one LB element did not light up. Note: In SCAN mode, the LB element of a GOUNDED conductor will not light up. Also, in a #5 Xbar office, it is normal for all the IP[A] conductors of non-busy pairs to be GOUNDED. his is the reason why this condition requires further investigation, to determine if the GOUND is normal to the pair or it can be a fault. 8

9 SCAN Mode Display Examples Bridge APICS 3322 or 3122 SPECIAL SCAN SPECIAL Fig. 10: SPECIAL (non-pos) Connect the Bridge to any pair and press SCAN key. he unit emits a single LO tone and displays a SPECIAL (non-pos) classification of the pair. Note: SPECIAL circuits are more sensitive and require more careful handling than regular POS lines. his is the reason why the unit goes into a pause to allow the operator to decide whether to go ahead with the pair ID or not. If the decision is to go ahead and identify the pair, then follow instructions in Fig. 10a. ED GEEN Fig. 10a: SPECIAL (non-pos) SCAN Press the SCAN key, twice to force the unit to identify the pair. he unit emits a single HI tone to indicate a clean (non-faulted) pair. he pair is identified to be Pair #8 which is also confirmed by the lighted LB elements. 9

10 MDF or X-Connect Box Pair ID Hookup & Procedure LB Mode Front ap Shoe Communication link between the CO & Field unit (any pair within the 100 pair group) is required and there must be continuity to at least one of the conductors Bridge 3121 CO Unit Pair to be identified Note: In the LB Mode, the pair or conductors to be identified must be grounded to identify therefore use this mode on inactive pairs, only. conductors to identify 3322 CO Unit ed to -48 to 52VDC CO Battery (eference Voltage) Note: It is possible not to connect the ED clip to the CO battery, the system should work normally. Only in this case, the reference voltage of -48VDC will be provided internally. Procedure: Very important: Cable Shield/ serves as the communication return path for both the CO and Field units. he cable shield must have continuity (no opens) from the CO to the field. If the cable shield is open use a any known good pair within the 100-pair group under test, instead. 1. With the Field unit ON, connect the BIDGE clip to any pair within the 100-pair group being worked on, the GOUND clip to the cable shield then press the LB key. Wait for the Field unit to emit the scanning tones (2 short beeps in succession). 2. ake any pair you wish to identify and ground each conductor one at a time or both at the same time. he LCD elements corresponding to that pair should light up on the LB screen. See examples on the following pages. 10

11 LB Mode Display Examples APICS 3322 or 3122 Bridge SENDING Fig. 1: GOUNDED Conductors LB If the operator is not grounding any pair, any LB element that lights up upon pressing the LB key is GOUNDED at some point along the cable length. In this case, ING[B] (Pair #6), IP[A] (Pair #14) and both conductors of Pair #23 are all GOUNDED. APICS 3322 or 3122 Bridge SENDING Fig. 2: NOMAL LB Display LB If both conductors of a pair are GOUNDED by the operator, the corresponding LB elements should light up. In this case, Pair #23 is identified. 11

12 LB Mode Display Examples SENDING LB Fig. 3: OPEN (One conductor only) If both conductors of a pair are GOUNDED by the operator and only one LB element lights up, then one side is OPEN. In this case, IP[A] of Pair #6 is OPEN. Bridge APICS 3322 or 3122 SENDING LB Fig. 4: OPEN (Both conductors) If both conductors of a pair are GOUNDED by the operator, and no LB element lights up, both conductors of the pair are OPEN. In this case, the OPEN fault must be cleared first before the pair can be identified. 12

13 SENDING LB Mode LB Fig. 5: COSS If both conductors of a pair are GOUNDED by the operator and other additional LB elements light up with the LB elements of the pair. a COSS (fault) exists between the pairs. In this case Pair #23 is identified but COSSED to Pair #14 as shown above. Bridge APICS 3322 or 3122 SENDING LB Fig. 6: SPLI If both conductors of a pair are GOUNDED by the operator, and the LB elements light up, as shown above, the pairs are SPLI. In this case, Pair #23 and #25 are SPLI. 13

14 LB Mode Display Examples Bridge SENDING Fig. 7: SHO LB When only one conductor of a pair is GOUNDED by the operator and the two corresponding LB elements to the pair light up, then the pair is SHOED. APICS 3322 or
