TM Hotwire 6020 MVL POTS Splitter Central Office Installation Instructions Document Number 6020-A2-GZ40-00 March 1998 About the Hotwire MVL POTS Splitter The Hotwire MVL (Multiple Virtual Lines) System enables simultaneous high-speed digital data access and analog voice service over the same twisted-pair telephone line. The simultaneous access to MVL and POTS (Plain Old Telephone Service) requires the installation of a POTS splitter at the central office (CO). A CO POTS splitter is not necessary when the MVL line is not used with analog voice for POTS. The POTS splitter filters out the MVL signal and allows the POTS frequencies to pass through. Each central office POTS splitter card contains 12 filters to serve 12 local loops with MVL-based service and POTS. The POTS splitter card is a passive device and requires no power. The POTS splitter chassis is shipped separately from the POTS splitter card(s). Two chassis are available:
1-slot chassis which can be placed on a tabletop or installed in a rack.
6-slot chassis which must be installed in a commercial EIA-standard 19″ or 23″ rack or cabinet. Before You Begin Consider the following before installing the POTS splitter:
Installation Site The location should be well-ventilated, clean, and free of environmental extremes. Allow clearance at the front of the POTS splitter chassis to provide access to the cables.
Cabling Three Telco 50-conductor cables are used to connect to the three interfaces on the POTS splitter card. The location of the system hardware affects the length of the three cables. Cables and Hardware You Need For each POTS splitter card, obtain three Telco 50-conductor cables with 50-position amphenol-type connectors at the appropriate length based on cabling requirements in your environment. Refer to Cabling Overview, page 11, and Connector Pin Numbers, page 17. 6020-A2-GZ40-00 March 1998 1 POTS Splitter Card Package Checklist Verify that your POTS splitter card package contains the following:

To plan the bracket and chassis installation, determine:
Width of the rack: 19″ or 23″.
Chassis position in the rack: center mounted or front mounted. Center mounted is recommended for convenient access to cables.
Whether the rack has mounting rails with threaded or non-threaded screw holes.
If a 1-slot chassis is being placed on a tabletop. If so, plan to install the rubber feet as shown on page 2. Discard rubber feet for any rack-mounted chassis. NOTE: In order to reduce the risk of accidental tip over, it is strongly recommended that the chassis be installed into the rack from the bottom up. 6020-A2-GZ40-00 March 1998 5 Installing the Brackets The brackets can be installed in the chassis in a center-mounting or front-mounting configuration. Mounting holes are provided in the chassis for either configuration. Install the appropriate 19″ or 23″ brackets on the 1-slot or 6-slot chassis. 1-Slot Chassis 19-Inch Rack 23-Inch Rack 98-15486-01 6-Slot Chassis Center Mount 23-Inch Rack Front Mount 19-Inch Rack 98-15434-01 Select one of the next two procedures for chassis installation in a rack. 6 March 1998 6020-A2-GZ40-00 Installation into a Rack with Threaded Screw Holes
Procedure After installing the appropriate brackets on the chassis: 1. Determine the preferred placement of the chassis in the rack. 2. Use the four Phillips-head mounting screws provided and a Phillips screwdriver to install the chassis. Front Rail Screw 97-15435 3. Tighten all four screws. To install the next chassis in the same manner, follow Steps 1 through 3. For a standard rack installation, chassis can be mounted directly on top of each other. Installation into a Rack without Threaded Screw Holes
Procedure After installing the appropriate brackets on the chassis: 1. Determine the preferred placement of the chassis in the rack. 2. Insert a speed nut onto each mounting rail hole selected and align the hole of the speed nut with the hole in the rail. 6020-A2-GZ40-00 March 1998 7 3. Use a Phillips screwdriver to install the: — 1-slot chassis in 19″ or 23″ rack, or a 6-slot chassis in a 19″ rack. — 6-slot chassis in a 23″ rack. Install the top two screws loosely enough to allow the bracket’s upper keyholes to drop under the screw heads during installation. 4. Line up the chassis-mounting bracket with the speed nut and start to rotate the speed nut screw into the chassis mounting bracket and the speed nut. 5. Loosely install the bottom screws first and then the top screws. Tighten each screw until the head is flush with the chassis and securely mounted in the rack. To install the next chassis in the same manner, follow Steps 1 through 5. For a standard rack installation, chassis can be mounted directly on top of each other. Installing the Ground Wire To comply with Network Equipment-Building Standards (NEBS) requirements, the ground wire must be installed.
Procedure 1. There is a ground lug on each chassis. Locate the ground lug. If you have a . . . Then the ground lug is . . . 1-slot chassis On the rear of the chassis on the left. 6-slot chassis On the front of the chassis on the top right.

Then the ground wire gauge must be . . . 1-slot chassis 10 — 14 AWG 6-slot chassis 6 — 14 AWG 3. Loosen the screw on the GND lug. 98-15879 4. Insert the stripped end of the wire into the open end of the GND lug and tighten the lug’s screw. Make sure that the wire is making contact with the stripped portion of the wire. 6020-A2-GZ40-00 March 1998 9 Installing the POTS Splitter Card in the Chassis
Procedure 1. Insert the POTS splitter card into the chassis. 2. Tighten the two 1/4-turn fasteners in the faceplate for each installed POTS splitter card.

Remove a filler panel and replace with a POTS splitter card, as needed. Keep filler panels in all unused slots. CO POTS Splitter 6-Slot Chassis Filler Panel 1/4-Turn Fastener DSLAM Interface Loop Interface PSTN Interface 1/4-Turn Fastener 98-15851 Cabling Overview The interfaces to both the POTS splitter and the DSLAM use 50-position amphenol-type connectors. Each MVL line uses a pair of copper wires. There are 12 pairs used on each 50-position connector for each POTS splitter card. The 12 pairs can be connected directly to the DSLAM using a straight-through cable or connected directly to the MDF. In order to directly connect 24 pairs, use a Y-cable to combine 12 pairs from two POTS splitter cards. 6020-A2-GZ40-00 March 1998 11 Cabling Examples The POTS splitter card supports 12 POTS lines, using only 12 pairs on the 50-position connector. The DSLAM 50-position amphenol-type connector feeds 24 MVL ports, comprised of six slots with four ports per MVL card slot. Interface connections:
DSLAM Interface connects to the 8800 DSLAM using a Y-cable. The Y-cable enables 24 POTS splitters to serve 24 DSL lines on the DSLAM.
LOOP Interface connects to the local loop via the main distribution frame.
PSTN Interface connects to the local PSTN switch. In the next example, the first two POTS splitter cards are combined using a Y-cable.

Procedure 1. Determine how the cables will be dressed. The cables can be dressed from either side based on the cable heads. Each cable head can have left-angle or right-angle heads. 2. Feed the cable head through the chassis’ front right or left opening. 3. Install the plastic tie-wrap anchor onto the faceplate on the cable exit side with the screws provided. 4. Slide the tie wrap through the anchor from the top. 6020-A2-GZ40-00 March 1998 15 5. Attach the cable head to the POTS splitter connector. — If the connector on the cable has a long screw, tighten the screw directly into the connector located in the circuit card. Discard the jack screws provided. Long Screw Anchor Mount 50-Pin Connector 97-15551 — If the connector on the cable has a short screw, install the #4-40 jack screw provided into the threaded hole of the connector in the circuit card. Attach the short screw in the cable to the jack screw and tighten. #4-40 Jack Screw Anchor Mount Short Screw 97-15552 6. Tighten the tie wrap and trim the excess. 97-15553 Repeat the procedure for all the interface cables. 16 March 1998 6020-A2-GZ40-00 CO POTS Splitter 6-Slot Chassis DSLAM Interface Loop Interface PSTN Interface 98-15848-01 Connector Pin Numbers Pin assignments are the same for all three connectors on the CO POTS splitter card. 50-Position Amphenol-type Connector Filter # Pin # Tip* Pin # Ring* 1 1 26 2 2 27 3 3 28 4 4 29 Pin 26 5 5 30 98-15482-01 6 6 31 7 7 32 8 8 33 9 9 34 10 10 35 11 11 36 12 12 37 Pin 1 Pin 25 Pin 50 *Pins 13—25 and 38—50 are not used. 6020-A2-GZ40-00 March 1998 17 Technical Specifications POTS Splitter 6020 Card Technical Specifications* Item Specification Height x Width x Depth 1.07″ x 15.77″ x 6.5″ (2.72 cm x 40.06 cm x 16.51 cm) Weight 1 lb. 3.7 oz.
