Procedure:

1. With the Field unit ON and the GROUND clip connected to the cable shield, connect the BRIDGE clip to any pair you wish to identify within the 100-pair group under test, then press the SCAN key. The pair number, color code and status of the pair will then be displayed on the screen. The LCD elements for the particular pair will also light up on the screen.

2. If SPECIAL(any service other than POTS) or UNBAL (unbalanced which means one side of the pair is grounded) is detected, the unit will pause. This 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. To force the unit to identify the pair, press the SCAN key twice. See examples on the following pages.

Pair to be identified - also serves as a communication link between the CO & Field unit. There must be continuity to at least one of the conductors.

Very important: Cable Shield/Ground serves as the communication return path for both the CO and Field units. The cable shield must havecontinuity (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.

Note: The “SCAN” Mode can be used to identify both active and inactive pairs.

Note: It is possible not to connect the RED clip to the CO battery, the system should work normally. Only in this case, the reference voltage of -48VDC will be provided internally.

Fig. 9: GROUND

Connect the Bridge Clip to any pair and press SCAN key. The 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. The 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: The GROUND can be verified by using the LTB mode and to force the unit to identify pair, follow instructions in Fig. 9a.

Fig. 9a: GROUND

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 LTB element did not light up.

Note: In SCAN mode, the LTB element of a GROUNDED conductor will not light up. Also, in a #5 Xbar office, it is normal for all the TIP[A] conductors of non-busy pairs to be GROUNDED. This is the reason why this condition requires further investigation, to determine if the GROUNDis normal to the pair or it can be a fault.

SPECIAL

Fig. 10: SPECIAL (non-POTS)

Connect the Bridge Clip to any pair and press SCAN key. The unit emits a single LO tone and displays a SPECIAL (non-POTS) classification of the pair.

Note: SPECIAL circuits are more sensitive and require more careful handling than regular POTS lines. This 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.

Procedure:

1. With the Field unit ON, connect the BRIDGE clip to any pair within the 100-pair group being worked on, the GROUND clip to the cable shield then press the LTB key. Wait for the Field unit to emit the scanning tones (2 short beeps in succession).

2. Take any pair you wish to identify and ground each conductor one at a time or both at the same time. The LCD elements corresponding to that pair should light up on the LTB screen. See examples on the following pages.

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

Note: In the “LTB” Mode, the pair or conductors to be identified must be grounded to identify therefore use this mode on inactive pairs, only.

Procedure:

1. With the Field unit ON, connect the Bridge clip to any pair within the 100-pair group being worked on and the GROUND clip to the cable shield. Enter the pair number you wish to identify using the numeric keys and then press the SELECT key. The Field unit will then send a command to the CO unit to place the interrupted ID tone on the pair number selected.

2. Take the TONE probe and locate the pair where the interrupted ID tone is on. You may activate the XPANDER to minimize tone bleed to the other pairs. Adjust the VOLUME level, accordingly. See examples on the following page.

Tone Probe

Note: The “SELECT” Mode uses “ Interrupted ID Tone” to identify a pair. It can be used for both active and inactive pairs.

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.


Note: It is possible not to connect the RED clip to the CO battery, the system should work normally. Only in this case, the reference voltage of 48VDC will be provided internally.

Press the appropriate numeric key to enter the pair number to identified. The number will then be displayed on the screen. Next step is to press the SELECT button. The field unit will now talk to the CO unit to send tone on pair #26. The LTB elements of Pair #26 will then light up and displays the pair color code to confirm that it was selected and that tone is already on it. The TONE Probe is then used to locate the tone. The pair with the strongest tone should be Pair #26.

To improve selectivity and minimize tone spreading or bleeding, press theXpander key. An X should appear under the function display box (see Fig. 11a).

2. Connect the “Battery” cable (“Black” clip to Ground and “Red” to the negative (-) terminal of the CO battery, if possible).

3. Connect the “Front Tap Shoe” between the CO unit and the 100-pair group to be identified at the MDF (Fig. 2).

5. Connect the Field unit’s “Ground” clip to the MDF system Ground (see Fig.4).

6. Connect the “Bridge” clip directly or through a jumper wire to any selected pair among the 100-pair group

under test at the MDF. (ex: pair #33).

7. Using the blue numeric keys, enter the selected pair number (ex: Pair # 33)

where the “ID Tone” will be put into and then press the <Select> key.

The Field unit then sends a command to the CO unit to put ID tone on

pair #33. The screen should display the following:

8. To verify that the “ID Tone” is already on the selected pair (pair #33), plug the Tone Probe into the Field unit.

Place the tone probe close to the selected pair or the Bridge clip (Fig. 7). The ID Tone should be heard from the

internal speaker. Adjust the volume level if necessary.

9. Once the ID tone is verified on the selected pair (Pair #33), turn the 3322 Field unit OFF, disconnect it from the

pair and proceed to the far-end of the cable.

10. Once out in the field, turn the Field unit ON, connect the GROUND cable to the cable shield, plug the tone PROBE into its jack and press the SELECT key to activate the tone PROBING process.

11. With the tone PROBE, look for the ID Tone on a pair. The ID tone should be on Pair #33. This should identify the 100 pair group under test. Note: As you close in to the pair with the ID tone, you may want to activate the Xpander by pressing the Xpander key. The Xpander function is used to minimize tone bleeding to other pairs.

12. Once the 100 pair group under test is identified, proceed to the normal Pair ID process using SCAN, LTB or SELECT Modes as the case maybe.
