High Density Block BRCP HD BRCP- 128/192/256 pair Installation Instructions
Product Introduction The BRCP block is the latest generation of MDF terminal blocks developed by 3M, specifically designed for xdsl deployment in the central office and remote sites for DSLAM interconnection with the existing main distribution frame (MDF). The BRCP high density terminal block is modular by design (16-pair modularity) and available in various pair counts enabling perfect match with most DSLAM line card configurations. The BRCP block features a swiveling front and rear side block providing a clear demarcation of two termination areas, one at the rear for the DSLAM vendor installation team (direct termination of DSLAM cables), the other at the front for the xdsl service provider team to jumper its DSL subscribers. 1.0 Kit Contents 3M TM High Density Terminal Block BCRP Note: Examine kit contents. Ensure that all components are present and that they are in a usable and defect free condition. A. 3M HD BRCP Block (1) B. Bolt & Nut M6x20mm (2) C. Cable Ties 2.5mmx100mm (24) - 2 -
2.0 Block Identification Terminology Management Rings Block back mount frame Jumper Rings Locking Latch Labels & Label Holder Line identification labels are located at the top of the front face of the block. Free marking area is located at the bottom of the front face of the block. Wire Guides (White or Black) The blocks can be installed horizontally, side by side, or vertically, one above the other. - 3 -
3.0 Mounting the Block 3.1 Disengage the locking latches and open the block. Each block element can be secured in the open position. Cable tie ports Cable port Note: When aligning the block onto the vertical frame, ensure that the cable tie ports and the cable port are not obstructed in any way. 3.2 Fix the block back mount frame on the vertical frame. 4.0 Rear Side Termination DSLAM IN & DSLAM OUT Cable Termination Note: Pair 1 on the inside is connected at the bottom of the block element. - 4 -
4.1 Route the cable towards the back of the block back mount frame. 4.2 Open the block element and pass the cable through the block back mount frame (leave a minimum of 15" (400 mm) of cable extending from the rear of the back mount frame.) 4.3 Cut the cable sheath approximately 1" (25 mm) from the rear of block back mount frame using company approved tools and practices. Note: Do not completely remove the cable sheath yet. 4.4 Slide the cable sheath down the conductors approximately 10" (250 mm). Note: Keep the outer jacket intact till the cable is out of the port. This would protect the cable from the edges of the port. 4.5 Organize the conductors in bundles of 16 pairs per company practice and color code. 4.6 Remove the remaining section of cable sheath off the conductors. - 5 -
4.7 Route the first bundle of 16 pairs of conductors through the management ring. Technical Tip for wiring: For smaller capacities, one half of the block (96 pairs) can be used for DSLAM in and the other half (96 pairs) can be used for DSLAM out. Technical Tip: To ensure sufficient slack during the routing of the pairs, use a piece of scrap cable (or cable jacket) and insert as shown. 4.8 Select the location for the desired pair and route the wires into the corresponding IDC slot. Note: Color code of pairs for internal terminations will be reversed from those of external terminations. 4.9 Terminate the pairs with the approved 3M Termination Tool SOR-OC. Straddle the tool on the IDC contact with the screw head facing toward the middle of the module. 4.10 Push the tool into the module until click is heard, signifying the IDC contact. - 6 -
4.11 Remove the wire scrap. 4.12 Route remaining pairs into their corresponding IDC slots. 4.13 Terminate all remaining pairs using the approved SOR-OC termination tool. 4.14 Use cable tie as shown and close the block. Cable Ties Note: Remove the piece of scrap cable (or cable jacket) that might have been used as previously described in the technical tip to ensure sufficient slack during the routing of the pairs. 5.0 Front side termination - Jumper wires Termination (coming from exchange side & line side blocks) Jumpers are terminated one pair at a time. The following steps will be repeated until all required jumper pairs are connected. External conductor terminations are opposite of internal terminations. Pair 1 on the outside is terminated at the top of the block element. Pair 1 for external termination - 7 -
5.1 Route jumper into the HD BRCP jumper ring. 5.2 Route the pair of conductors into the wire guide, per company practice and color code. 5.3 Pull the pair of conductors over the corresponding IDC slots, and split the conductors between the slots. 5.4 Terminate the pairs with the approved 3M Termination Tool SOR-OC. Straddle the tool on the IDC contact with the screw head facing toward the middle of the module. 5.5 Push the tool into the module until click is heard, signifying the IDC contact. 5.6 Remove the wire scrap. 5.7 Repeat steps 5.2 through 5.6 until the required jumper terminations are complete. - 8 -
6.0 Testing the 3M High Density Block BRCP 6.1 Test Plug To test the HD BRCP block, the 3M Test Plug (SORIB) should be used. Insert the test plug to the port to be tested in the block. This is a polarized test plug; hence it cannot be flipped in the reverse direction. Please ensure that the arrow marked on the rear side of the test plug housing, faces upwards while inserting the test plug. Note: Ensure that the test plug is not inserted in the reverse direction (arrow facing downwards) 6.2 Block Testing To test a pair of upper ports (port no. 1-8) in the module, use the black and red wires at the open end of the test cord, after inserting the plug. To test a pair of lower ports (port no. 9-16) in the module, use the yellow and green wire at the open end of the test cord, after inserting the plug. 7.0 Accessories Termination Tool Test Plug - 9 -
