7 1 PRODUCT INTRODUCTION This section describes the ADC Next Generation Cross-Connect NCX-1000 Small-Size Service Delivery Cabinet, hereafter also called the NCX-1000 or NCX-1000 cabinet. 1.1 General Description The NCX-1000 small-size cabinet is a secure, above-ground, outdoor cabinet that provides a distribution intercept (DI, 1:1) for OSP cables. The cabinet is intended for a telephone-based network that is in the process of being upgraded to xdsl service. Figure 1 shows an example. Figure 1. NCX-1000 Small-Size Service Delivery Cabinet Physically, the small-size NCX-1000 has an active area and a passive area. The active area contains mounting provisions for a hardened DSLAM and the associated electronics required to combine Plain Old Telephone Service (POTS) with the enhanced services available through xdsl. The passive area consists of an intercept enclosure containing ADC Series 2 disconnect and switching blocks. When a service upgrade is ordered for a specific subscriber, a service technician installs jumpers that route the POTS circuit for that subscriber into the DSLAM and out again to the subscriber with the POTS+DSL signal. Page 1

8 Jumpers are only required when POTS service is upgraded to POTS+DSL. A test jack module, provided with the cabinet, can be used for circuit testing. The NCX-1000 cabinet can be pad- or pole-mounted. It is constructed of heavy gauge aluminum and is coated with an almond-colored finish. The cabinet has dual front doors with tamper-resistant latches. It has hasps for padlocks, stainless steel hinges, and door catches to prevent accidental closing. Access to the cabinet requires a 216B key tool (accessory). The intercept enclosure within the cabinet is secured with the same 216B tool. Lifting rings allow use of hoisting equipment. The NCX-1000 has a grounding bus used for grounding the cabinet. Each cabinet is equipped by the factory with pre-terminated OSP cables 3 ft. (91.44 cm) in length. Within the cabinet, these cables are terminated to the disconnect blocks used for OSP input and output connections. Stub ends of cables are terminated to splice connectors for splicing to a network interface cable. Switching blocks used for POTS input to the DSLAM and xdsl output are equipped with pre-terminated cables 3 ft. (91.44 cm) in length and terminated to splice connectors. These connectors are used to connect to the DSLAM when installed. 1.2 Cabinet Function The NCX-1000 cabinet provides an intercept point, somewhere along the course of a network cable, where DSL service can be added on demand to POTS-carrying twisted pairs. Figure 2 shows how a cabinet is positioned in a typical network.

11 Enclosure Door: provides secure access to the intercept enclosure. Items mounted on this door include a jumper wiring label and a designation label. Series 2 Disconnect Blocks: provide cross-connect and test access to the twisted pairs of the pre-terminated network cables. These blocks are white in color. Series 2 Switching Blocks: provide cross-connect and test access to the individual twisted pairs of the pre-terminated DSL input and output. These blocks are brown in color. Jumpers, installed between the Series 2 disconnect blocks and switching blocks combine POTS and DSL to provide broadband capacity for an upgraded subscriber. NT Power Blocks: provide a connection point for power input to the DSLAM when line powering is used. Site Mounted Test Cord: provides test access to an individual circuit including monitor and look-both-ways testing without removing wires. Vertical Cable Management Rings: are used to route jumpers vertically in the cabinet between rows of termination blocks. Cables: connect the Series 2 blocks to pre-terminated OSP cables 3 ft. (91.44 cm) in length and terminated with splice connectors. DSLAM: is a hardened unit that combines an enhanced signal, received by optical fiber or copper feed from the central office, with the POTS signal received from a remote cabinet or the central office. Note: The NCX-1000 small-size cabinet is shipped without a DSLAM. One or more DSLAMs of a type selected by the customer are installed in the field. Integration Box: is a customer installed aggregation unit or equivalent device (not provided), if required for the type of DLAM being used. Lifting Rings: are used to hoist the cabinet into position. Ground Posts: are used to attach a ground wire. Green Disconnect Plugs: (not shown) are used in Series 2 disconnect blocks to activate a xdsl circuit after the jumpers for the circuit have been installed. Page 5

12 1.4 Termination Blocks (Three Types Used) Three types of termination blocks are used in the NCX cabinet. All of these types feature 45- degree angled silver-plated contacts, built-in test ports, and insulation clamping ribs to protect the termination against vibration and mechanical stresses Series 2 Switching Block (Non-Protected) 10-pair Series 2 Switching Blocks (example shown in Figure 6) are used for DSL in and out connections. These blocks are brown in color A Figure 6. Series 2 Switching Block (Non-Protected) When the cabinet is shipped, these blocks are pre-terminated to OSP cables with 3-foot (91.44 cm) stubs that in turn are terminated to splice connectors. The splice connectors are used to splice the stubs to cables linking the cabinet to the internal DSLAM. These blocks have a normally-open contact between the punch-down terminals. When a twisted pair is installed and punched into a circuit position, the circuit is ready to be activated Series 2 Disconnect Block 10-pair Series 2 Disconnect Blocks (of which an example is shown in Figure 7) are used in NCX-1000 cabinets for OSP IN/OUT connections. These blocks are white in color. DISC A Figure 7. Series 2 Disconnect Block When the cabinet is shipped, these blocks are pre-terminated to OSP cables with 3-foot (91.44 cm) stubs that are in turn terminated to splice connectors. At the installation site, the splice connectors are used to splice the stubs to a network interface cable. Page 6

13 These blocks are closed between the OSP input and output positions within each block. Therefore, there is no need to use jumpers when adding POTS subscribers in a NCX-1000 cabinet. Jumpers are only required when a POTS circuit is upgraded to add DSL service. This block has a normally-closed contact between the punch-down terminals. When the OSP input and ouput circuits are jumpered to the DSL blocks to add DSL service, a green disconnect plug (shown in the figure) is inserted into the center hole of the OSP block to open the contact. This causes the Normally Closed contacts to open NT Power Pairs Caution: Use caution when accessing the NT power blocks. The NT power blocks have a high voltage potential (up to 191 VDC). 10-pair NT Disconnect Blocks (example shown in Figure 8) are used in the NCX-1000 smallsize cabinet to provide a power interface when line powering is used for the DSLAM(s). These blocks are white in color. When the cabinet is shipped, these blocks are pre-terminated to cables with 3-foot (91.44 cm) stubs that in turn are terminated to splice connectors A Figure 8. NT Power Block NT power blocks have a normally-closed contact between punch-down terminals. When a twisted pair is installed and punched into a circuit position, the circuit becomes active at once.

Do not stand in the hole while placing the FMS in position. An unexpected shift of the FMS could result in personal injury. Use the following procedures to place the FMS into the excavation. 1. Fill the bottom of the hole with stone aggregate, tamping it as it is filled to build a 12 inch (30.5 cm) layer with a level surface. The stone aggregate will provide a stable base to support the FMS. Note: Use crushed rock 3/8-inch or less in size mixed with stone dust (per local practice) to fill the hole. The name of the material may differ in different geographical areas. Possible names are Class 5, stone dust, aughts (0s) and ones (1s), or stone aggregate Page 14

21 2. Use appropriate lifting equipment to place the FMS into the center of the hole. Lifting loops are provided on either side of the FMS for attaching a sling or chain. 3. Use a carpenter s level to verify that the FMS is level. If it is necessary to add or remove fill for leveling, tamp any added fill to maintain the base stability. 3.4 Cable Conduit Installation Select the conduit entrance holes (see Figure 12) for the OSP feeder and distribution cables and the optical fiber from the Central Office. If necessary, additional conduit entrance holes may be cut using a power drill and hole saw. Place and route the conduit into the entrance hole(s). If preferred, the FMS may be installed without conduit. Cables may be routed into the FMS at any point that is convenient. Cut the cable entrance hole to match the size of the cable. 3.5 Grounding System Installation 3.6 Back Fill Install a grounding system (not provided) that meets all local electrical codes. Check local codes for grounding system installation, use of clamps, wire size, and any other grounding requirements. Typically, #6 AWG copper wire is used for the grounding wire. Install the grounding system inside the FMS where it will not interfere with the conduit or cables. Connect the grounding wire to the grounding system, Leave sufficient slack in the grounding wire to allow it to be routed into the cabinet after the cabinet is mounted on the sleeve. Avoid sharp bends in ground wire. A sharp bend in the ground wire greatly decreases the effectiveness of the grounding system. If installing conduit, hand shovel stone aggregate under the conduit to avoid damage from the power tamper. Complete the back fill as follows: 1. Add stone aggregate evenly around the FMS and tamp. Fill to approximately 6 inches (15.2 cm) from the top of the excavation. 2. Complete the back-fill with crushed rock or topsoil depending on the landscaping requirements. The top surface of the mounting sleeve may be located from 0 to 4 inches (10.2 cm) above the surrounding grade (see Figure 12). 3.7 Mounting the Cabinet on the ACE100-KIT-A Use the following procedure to mount the NCX-1000 pad-mount cabinet on the FMS. Use the 216B key tool to un-latch and latch the cabinet doors as needed during the mounting process. Refer to Figure 13 as necessary during the installation. Warning: Use appropriate lifting equipment when moving or installing the cabinet. Do not stand under a cabinet as it is being hoisted into position for mounting. A failure of the lifting equipment could result in serious personal injury. 1. Mount the FMS adapter cover on the FMS and secure using the two capscrews and flat washers provided. Tighten each capscrew securely. Page 15

22 2. Place the isolation gasket (provided with cabinet) on the adapter cover and align the holes in the gasket with the holes in the adapter cover. Make sure the CABINET FRONT side of the gasket is the front side of the cabinet. 3. If a split skirt riser (optional accessory) will be installed, place the split skirt riser in position for mounting on the adapter cover. The isolation gasket installed in step 2 should remain in place between the adapter cover and ground spacer. If a split skirt riser will not be installed, proceed to step Align mounting holes in split skirt riser with the mounting holes in the adapter cover. 5. Secure the spacer to the adapter cover using the four capscrews, four lock washers, and four flat washers provided with the split skirt riser. Tighten all capscrews securely. 6. Using appropriate lifting equipment, hoist the cabinet several feet into the air to provide access to the feeder and distribution cables. Danger: Do not stand directly under the cabinet as it is being hoisted into position for cable installation. A failure of the lifting equipment could result in serious personal injury. 7. Position the cabinet over the rectangular hole in the adapter cover. 8. Route the DSLAM feeder cable from the Central Office through the hole in the adapter cover and into the NCX-1000 through the smaller of the two cable entry holes in the bottom of the cabinet (Figure 14). For connection details, refer to Section 6 on Page 30. If the cable has a metallic element, ground it to the grounding lug shown in Figure Route the OSP interface cable through the hole in the adapter cover and into the NCX through the larger of the two cable entry holes in the bottom of the cabinet (Figure 14). For connection details, refer to Section 7 on Page 33. If the cable has a metallic element, ground it to the grounding lug shown in Figure 15. Note: Avoid sharp bends in ground wire. A sharp bend in the ground wire greatly decreases the effectiveness of the grounding system. 10. Insert the grounding wire (installed in Section 3.5) through the smaller entry hole in the bottom of the cabinet (with feeder cable). Pull through several feet of slack. 11. Lower the cabinet onto the adapter cover or spacer and align the mounting holes in the bottom of the cabinet with the holes in the cover or spacer. If a split skirt riser was not installed, the isolation gasket installed in step 2 should be left in place between the adapter cover and cabinet. 12. Secure the cabinet to the adapter cover or split skirt riser using the four capscrews, four lock washers, and four flat washers provided. Tighten all four capscrews securely. 13. Tear off the perforated edge strips located on the left and right sides of the installed isolation gasket and discard. 14. Attach the grounding wire to the grounding lug as shown in Figure 15. The grounding lug can be used for #6 #14 AWG wire. Tighten the grounding lug set screw securely. 15. The lifting eyes may be left in place or removed from the cabinet. To remove the lifting eyes, use the security key tool (accessory) to remove the lifting eye screws. Store the lifting eyes inside the cabinet and then re-install the lifting eye screws in the cabinet. Page 16

Constructing the Concrete Pad for the NCX-1000 Cabinet 4.3 Grounding System Installation Install a grounding system (not provided) that meets all local electrical codes. Check local codes for grounding system installation, use of clamps, wire size, and any other grounding requirements. Typically, #6 AWG copper wire is used for the ground wire. If the grounding system includes a ground rod, install the rod outside the area of the concrete pad in natural soil (see Figure 17 on Page 20). From the grounding rod, route the grounding wire to the location marked for the bottom of the cabinet and leave a service coil of wire at that location. Page 20

27 Dig the wire into the ground slightly so that it will wind up below the concrete pad when the pad is poured. Leave sufficient slack in the grounding wire to allow it to be routed into the cabinet after the cabinet is mounted on the pad. Avoid sharp bends in grounding wire. A sharp bend in the grounding wire greatly decreases the effectiveness of the grounding system. 4.4 Concrete Pad Construction Use the following procedure to construct the concrete pad: 1. Build a wood form for the concrete pad using 2 x 6 framing lumber as shown in Figure Locate the PMF as shown in the construction diagram (see Figure 17). When installed, the top surface of the PMF must be flush and level with the top of the concrete pad. Note: Use temporary top framing to keep the top surface of the PMF flush and level with the top of the concrete pad (see Figure 18). 3. Place reinforcing material inside the form but outside of the PMF. DIMENSIONS SHOW FINISHED SIZE OF CONCRETE PAD 42 IN. (106.7 CM) 42.5 IN.

NCX-1000 Cabinet Concrete Pad Framing 4. Verify that the PMF and form are level. Depending on the landscaping requirements, the top surface of the concrete pad may be 0 to 3 inches (0 to 7.6 cm) above the final grade. The weld nuts are covered with plugs which must be left in place until the enclosure is mounted. 5. Pour the concrete to form the pad. Note: Do not pour concrete into the center area of the PMF. Page 21

28 Note: Allow some concrete to flow under the flanges on the bottom of the PMF so the PMF will be locked in place when the concrete hardens. However, do not allow concrete to fill the center of the PMF. If necessary, partially fill the center of the PMF with sand or gravel to prevent an inflow of concrete. 6. Remove the top framing and the temporary support wires when the concrete is ready to be finished. 7. Allow concrete to cure before proceeding with the installation. 4.5 Mounting the Cabinet on the Concrete Pad Use the following procedures to mount the NCX-1000 small-size cabinet on the concrete pad. Use the 216B key tool to un-latch and latch the cabinet doors as needed during the mounting process. Refer to Figure 19 as necessary during the installation. Warning: Use appropriate lifting equipment when moving or installing the cabinet. Do not stand under the cabinet as it is being hoisted into position for installation. A failure of the lifting equipment could result in serious personal injury. 1. Remove the plastic plugs that are installed in the threaded corner holes of the PMF and clean off any concrete that may have adhered to the top of the PMF. Note: Make sure all remnants of concrete are removed from the PMF prior to mounting the cabinet. It is not necessary to use shims to level or align the cabinet as long as the top surface of the PMF is clean and free of any installation debris. 2. Place the isolation gasket (provided with cabinet) on the PMF and align the holes in the gasket with the holes in the PMF. Make sure the CABINET FRONT side of the gasket (look for markings on the gasket) is on the side of the PMF that corresponds to the front side of the cabinet. 3. If a split skirt riser (optional accessory) will be installed, place the split skirt riser in position for mounting on the PMF. The isolation gasket installed in step 2 should remain in place between the PMF and split skirt riser. If a split skirt riser will not be installed, proceed to step Align the mounting holes in the split skirt riser with the mounting holes in the PMF. 5. Secure the spacer to the PMF using the four capscrews, four lock washers, and four flat washers provided with the split skirt riser. Tighten all capscrews securely. 6. Using appropriate lifting equipment, hoist the cabinet several feet into the air to provide access to the feeder and distribution cables. Danger: Do not stand directly under the cabinet as it is being hoisted into position for cable installation. A failure of the lifting equipment could result in serious personal injury. 7. Position the cabinet over the concrete pad and the PMF or split skirt riser. Page 22

Grounding Wire Connection To Cabinet 5 MOUNTING THE POLE-MOUNT CABINET ON A UTILITY POLE The NCX-1000 pole-mount cabinet is specifically designed for mounting on a utility pole. The cabinet is equipped with an integral pole-mount bracket system. A pole mount kit (catalog number OSP-PMK-001) is required. The kit is available from ADC and must be ordered separately. 5.1 Installation Recommendations The site chosen for the installation must conform to all local codes and any permits required must be obtained prior to the start of installation. The location must be accessible and provide adequate parking for worker and vehicle safety. The installed cabinet must not create a visual or physical obstruction to vehicular or pedestrian traffic or block pole-climbing access. Ensure that there is sufficient space on all sides to facilitate cabinet installation. The cabinet mounting bracket must be secured to the utility pole with 5/8-inch or 3/4-inch through-bolts or threaded rods (not provided). Page 25

32 5.2 Pole Loading Analysis A pole loading analysis should be performed before the NCX-1000 cabinet is mounted on the pole to verify that the pole can support the weight of the cabinet in various conditions. The weight of a fully loaded cabinet is 100 lbs. (45.36 kg). Three load types should be considered: static weight loading, ice loading, and wind loading. These types should be considered on the pole, wires, and any equipment installed on the pole. A qualified engineer should perform the pole loading analysis, taking into account both vertical and horizontal forces. 5.3 Grounding System Installation Install a grounding system (not provided) that meets all local electrical codes. Check local codes for grounding system installation, use of clamps, wire size, and any other grounding requirements. Typically, #6 AWG copper wire is used for the grounding wire. Bond the cabinet grounding wire to the MGN (Multi-Grounding Neutral) vertical grounding connector if one exists, or install a grounding stake in natural soil near the base of the pole for the grounding wire connection. Leave sufficient slack in the grounding wire to allow it to be routed to the cabinet. Avoid sharp bends in the grounding wire. A sharp bend in the grounding wire greatly decreases the effectiveness of the grounding system. 5.4 Mounting the Cabinet Note: A pole mount kit (catalog number OSP-PMK-001) is required. The kit is available from ADC and must be ordered separately. Use the following procedure to mount the NCX-1000 pole-mount cabinet on a utility pole: Warning: Use appropriate lifting equipment when moving or installing the cabinet or the mounting kit. Do not stand under the cabinet or mounting kit as it is being hoisted into position for installation. A failure of the lifting equipment could result in serious personal injury. 1. Determine the mounting location for the cabinet 2. Place the cabinet top support bracket (provided separately with the cabinet) in position for mounting on the utility pole as shown in Figure Mark the location of the support bracket mounting hole (use top hole) on the pole. 4. Drill a 5/8-inch hole into the utility pole at the point marked in step Secure the top support bracket to the utility pole using a through-bolt or threaded rod, flat washer(s), locking washer(s), and nut(s). Tighten nut(s) securely. Note: The fasteners specified in step 5 are not included with the cabinet and must be provided by the installer. 6. Using appropriate lifting equipment, hoist the cabinet into position for attachment to the utility pole. Page 26

Install a green activation plug to activate service. 9 MAINTENANCE AND REPAIR PROCEDURES 9.1 Painting Brush-in-cap type bottles of paint are available for touching-up nicks and scratches in the factory coat of paint. Lightly sand the area to be painted and then clean it thoroughly to remove any dirt, dust, or foreign matter. Shake the paint bottle until thoroughly mixed and then apply a light coat of paint to the damaged area using the small brush attached to the cap. Wait until the paint is dry and then apply a second coat if necessary. When finished painting, replace the paint bottle cap and tighten securely. Page 37

44 9.2 Door Gasket Replacement Damaged door gaskets may be replaced using the door gasket kit which includes a roll of gasket material. The ideal installation temperature for the adhesive used on the replacement gaskets is between 60 and 100 ºF (16 and 38 ºC). Installation is not recommended if the temperature is below 50 ºF (10 ºC). Remove any damaged sections of gasket material from the door. If necessary, use a citrus based adhesive cleaner to remove any adhesive that may stay attached to the door. Cut replacement lengths of gasket material from the roll as needed. Remove the paper backing to expose the adhesive and then carefully apply the replacement gasket to the door. 10 TESTING PROCEDURES 10.1 Test Procedures Using ADC Test Jack Module Testing procedures are done using a test jack module such as shown in Figure 34. Each cabinet contains a test jack module mounted on the cabinet door. When using a test jack module, insert the test plug into the desired location with black stripe up. The black stripe represents the Central Office side of the circuit. MON/LBW SWITCH TEST JACK MODULE TERMINATION BLOCK RJ11 RECEPTACLE BLACK STRIPE TERMINAL POSTS (4) TEST PLUG A Figure 34. Test Jack Module (Series 2 Shown) Line Monitoring (Bridged Circuit) Note: Test cord insertion is make-before-break but is not intended to be non-intrusive. Page 38

45 Perform the following steps: 1. Place the MON/LBW switch in the MON position. 2. To monitor the line, do either of the following: a. Clip a test set to the left terminal posts on the test jack module; or b. Insert an RJ11 plug equipped with a test set into the RJ11 receptacle on the test jack module Look-Both-Ways Testing (Open Circuit) This procedure interrupts the circuit to test either the feed side (IN) or the cross-connect side (OUT). Perform the following steps: 1. Place the MON/LBW switch in the LBW position. 2. Test the feed side by clipping a test set onto the left terminal posts of the test jack module. 3. Test the cross-connect side by clipping a test set onto right terminal posts Procedures Using Standard (non-adc) Test Cord Turning Up a Broadband Circuit To turn up Broadband circuit, use the following procedure: 1. Insert the Look-Both-Ways (LBW) test cord as follows: Note: If using a site mounted test cord, flip the switch to monitor mode for the equivalent of plugging the red and black leads together in the following steps. a. Insert the test cord in monitor mode into OSP block (white). b. Connect the long and short red leads together. c. Connect the long and short black leads together. d. Verify that the black stripe is facing upward. 2. Confirm that the circuit is idle. 3. Set test cord into LBW mode (disconnect red-to-red and black-to-black connections). 4. Look toward dial tone source; verify DT (long lead). Page 39

46 5. Look toward cable pair; verify CP (short lead). 6. Remove the test cord from the OSP block. 7. Insert the test cord into the DSLAM block (brown). 8. Verify sync with DSLAM (long lead). 9. Remove the test cord. 10. Install jumpers between OSP block and DSLAM input/output block (ensure that jumpers are installed correctly so that dial tone source is connected to DSLAM input, and DSLAM output is connected to OSP cable pair out). 11. Insert a green activation plug into the OSP block Testing a Voice Circuit To test a voice circuit, use the following procedure: 1. Insert the LBW test cord as follows: Note: If using a site mounted test cord, flip the switch to monitor mode for the equivalent of plugging the red and black leads together in the following steps. a. Insert the test cord in monitor mode into OSP block (white). b. Connect the long and short red leads together. c. Connect the long and short black leads together. d. Verify that the black stripe is facing upward. 2. Confirm that the circuit is idle. 3. Set the test cord into LBW mode (remove red-to-red and black-to-black connections). 4. Look toward dial tone source (long lead). Page 40

47 Testing a Working Broadband Circuit To test a working broadband circuit, use the following procedure: 1. Insert test cord in LBW mode into DSLAM block (brown). 2. Monitor (short lead) for testing dial tone coming from source and toward DSLAM. 3. Monitor (long lead) for testing the Data/voice service coming from the DSLAM toward the customer. Note: In some cases, to test sync with DSLAM using a xdsl test set, the jumper at the OSP block (bottom row) toward customer may need to be lifted. The green activation plug must be removed to do this. This will remove the customers modem (if present) from the circuit. In many cases, DSL test sets bridged with the customers modem will cause problems in testing as the test set acts as a modem also so there are two modems trying to sync from a single DSLAM port. 4. After removing the jumper, insert a green activation plug prior to testing. This will reestablish the electrical path correctly for testing. 5. If jumper was removed for sync testing, re-terminate the jumper on the OSP block bottom row. Remove the green activation plug prior to re-terminating jumper. 6. Insert green activation plug to re-establish the correct electrical path for the broadband circuit. Page 41
