They are as follows; DOOR TEST JACK MODULE DESIGNATION LABEL CABLE PASS-THROUGH HOLES (PUNCH OUT) DOOR LATCH GROUNDING STUDS TERMINATION BLOCKS (S2 OR S10) A Figure 4. Main Components of Add-On Cabinet Door: may be hinged on either left or right. Usually, it is desirable to have the door swing to the rear of the existing cabinet. Test Jack Module: may be inserted into an S2 or S10 block for circuit testing. Two types of test are possible: line monitoring (bridged circuit) or look-both-ways (open circuit). Note: The S10 block has only a bridged circuit mode (monitor). LBW (look both ways) is not possible on S10 blocks. Designation Label: provides a means to record the use of the block termination points as they are connected to jumpers. Page 3

10 Cable Pass Through Holes: may or may not be punched out depending on the use of the cabinet. The holes are used for passing through a network cable or for routing jumpers to the crossbox. The add-on cabinet also has floor cable portals for optional use. Door Latch: secures the cabinet. The door opens with an ADC 816 hex tool. Grounding Studs: provides a means to ground the cabinet. Termination Blocks: are used to connect jumpers. These blocks are pre-terminated in the factory to 3-foot (66 cm) OSP cable stubs.

The reason for shifting the panel is to provide better access to the pass-through holes for the cable and jumpers. The panel is shifted by lifting it up and moving it by hand; it has metal clips that hang on slots A PANEL IN SHIPPING POSITION PANEL SHIFTED LEFT PANEL SHIFTED RIGHT Figure 6. Panel Shift Positions Page 5

12 1.6 Panel Rotation Depending on which side of the crossbox the add-on cabinet is mounted, the panel can be rotated upward to the left or right to access the rear side of the blocks, as shown in Figure 7. This is done to splice incoming cables from a DSLAM or BLC (derived carrier system). Normally, this is not required because the blocks are pre-terminated in the factory. PANEL ROTATED LEFT (COVER AND DOOR REMOVED) PANEL ROTATED RIGHT (COVER AND DOOR REMOVED) A Figure 7. Panel Rotated Left and Right (0verhead View) 1.7 Termination Blocks (Two Types Used) Two types of termination blocks are used in the add-on cabinet. 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 8) are used in the add-on cabinet to provide the jumper connection between the feed and distribution cables in the crossbox and the adjunct DSLAM cabinet. These blocks are brown in color A Figure 8. Series 2 Switching Block (Non-Protected) Page 6

13 When the enclosure is shipped, the rear termination points on these blocks are pre-terminated to an OSP cable with a 3-foot (66.04 cm) stub. During installation, the cable is typically spliced to another cable that terminates at the adjunct DSLAM cabinet. Depending on customer order, the cable stub will be terminated with either 710 or MS2 splice connectors. 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. Note: Use only 24 AWG jumper wire for cross-connecting or activating circuits Series 10 Switching Block 10-pair Series 10 Blocks (shown in Figure 8) are used for straight-through connections. In the add-on cabinet, these blocks provide the connection between the crossbox distribution cable and the broadband loop carrier system. These blocks are white in color A Figure 9.

14 3 INSTALLATION The main steps in installation are determining how the add-on cabinet will be used, punching out the cable holes to be used, mounting the add-on cabinet on the crossbox, and routing and splicing the cable stub. Use the following procedure. 1. Determine the following based on the installation plan for the add-on cabinet: a. Is this add-on cabinet equipped with S2 or S10 blocks? Refer to Section 1.2 on Page 1 for a comparison of the two applications. b. Will the add-on cabinet be mounted on the left side or right side of the crossbox cabinet? Note the door is field reversible to provide for swinging in either direction. c. Will the network cable (pre-terminated stub) be routed through the cross-connect cabinet or will it be routed through the bottom of the add-on cabinet. For an illustration of the two routes, refer to Figure 2 and Figure 3 on Page 2. d. Note, also, through which holes the jumpers will be routed. Normally, the jumpers pass through the front side of the cabinet (leftmost holes on rightside add-on cabinet, rightmost holes on leftside add-on cabinet). 2. Based on the expected cable routing, shift the termination block panel to the left or right. Note: To shift the termination block panel, lift it off the slots it is hanging on and move it across to the new position it. For an illustration, see Figure 6 on Page Using a hole puncher, punch out the holes selected for jumper and cable pass-through. 4. Open the crossbox to provide a clear view of the side of the crossbox on which the add-on cabinet will be mounted. 5. With the assistance of another person: a. Exactly position the add-on cabinet on the side of the crossbox cabinet and hold the cabinet steadily in place. b. Mark the position on the crossbox of the add-on cabinet mounting holes shown in Figure 10. c. Mark the location on the crossbox of the cable holes punched out of the add-on cabinet in step 2. d. Temporarily set aside the add-on cabinet. 6. Drill holes on the side of the crossbox for the mounting screws locations just marked. 7. Using a hole puncher, punch out the holes on the side of the crossbox for the cable hole locations just marked. Page 8

15 MOUNTING HOLES MOUNTING HOLES A Figure 10. Location of Mounting Holes in Add-On Cabinet 8. Mount the add-on cabinet on the side of the cross-box using four screws installed in the mounting holes just drilled (shown in Figure 10). 9. Install conduit sleeves and seals (provided) in the cable holes punched out in the add-on cabinet and crossbox. 10. Route the stub cable through the chosen physical route to the splice location for the network cable (or if the adjunct DLSM cabinet or broadway loop cabinet). 11. Splice the cable stub to the network cable or termination interface. 12. Close the add-on box if jumpering will not be done at this time. Page 9
