FCC ID: F8I-DLC1902A ADCP-75-158 • Preliminary Issue A • June 2003 • Section 2: Description The NOC/NEM interface is a command line interface that is presented at an NOC terminal. The NOC/NEM interface is used for remote control and monitoring operations. The NOC/NEM interface consists of ASCII text strings that are input as standard SET or GET commands which are followed by the action or information required. A text string response is received from the specified system or systems to confirm the requested action or to report the requested information. Examples of several typical NOC-NEM interface commands and the responses received are shown in Figure 2-19. The NOC/NEM interface requires only a VT100 terminal/ emulator or a PC-type computer that is loaded with a communication software such as Procomm Plus. While primarily intended for use at the NOC, the NOC/NEM interface commands may also be input from the EMS computer. Figure 2-19.

Installation of the RU outdoor cabinet or RU indoor mounting shelf and the RU electronic modules may proceed separately from installation of the HU. The mounting procedures for the outdoor remote cabinet are provided in the 20 Watt Outdoor Remote Cabinet Mounting Instructions (ADCP-75-147) which are shipped with the cabinet. The installation procedures for the STM and LPA electronic modules are provided in the 20 Watt Indoor Remote Unit Installation Instructions (ADCP-75149) and the 20 Watt Outdoor Remote Unit Installation Instructions (ADCP-75-148) which are shipped respectively with the outdoor cabinet and indoor mounting shelf. When all units of the Digivance system have been installed, refer to Section 4 of this manual for the system turn-up and test procedures. Before beginning the installation, review the system design plan with the system engineer. Make sure each equipment installation site is identified and located and all cable runs are mapped out. 1.1 Tools and Materials The following tools are required to complete the procedures in this section: • Box cutter • Pencil or scribe • Medium size flat-bladed screwdriver Page 3-1 © 2003, ADC Telecommunications, Inc. ADCP-75-158 • Preliminary Issue A • June 2003 • Section 3: Host Unit Installation • • • • • • • • Phillips screwdriver (#2) TORX screwdriver (T20 bit) Pliers Wire cutters Wire stripper Tool kit for attaching N-type male connectors to coaxial cable Multimeter Optical power meter The following materials are required to complete the procedures in this section: • • • • • • • • • 1.2 #18 AWG (1.0 mm) insulated stranded copper wire (for chassis grounding wire) #18 AWG (1.0 mm) red and black insulated copper wire (for DC power wires) Category 3 or 5 cable (for external alarm system wires) #6 ring terminal (1) for #18 wire (for chassis ground wire connection) #6 fork terminals (2) for #18 wire (for DC power wiring connection) Single-mode patch cord(s) with SC connectors (1, 2 or 3 depending on the application) High performance, flexible, low-loss 50-ohm coaxial cable N-type male connectors Wire ties Unpacking and Inspection This section provides instructions for opening the shipping boxes, verifying that all parts have been received, and verifying that no shipping damage has occurred. Use the following procedure to unpack and inspect the HU and any accessories: 1. Open the shipping cartons and carefully unpack each component from the protective packing material. 2. Check each component for broken or missing parts. If there are damages, contact ADC (see section 6 at the end of this manual) for an RMA (Return Material Authorization) and to reorder if replacement is required. FIBER OPTIC CABLE ROUTING AND INSTALLATION GUIDELINES The outside plant (OSP) fiber optic cables should be routed between the HU and RU and terminated before the equipment is installed. A diagram of a typical fiber optic cable routing is shown in Figure 3-1. At the HU, the OSP cable should be terminated at a fiber distribution panel and spliced to pigtails. Patch cords may then be used to link the HU optical ports to the OSP cable terminations. Whenever possible, a guideway such as the FiberGuide system should be provided to protect the fiber optic patch cords from damage and to prevent excessive bending. The procedures for connecting the OSP cable optical fibers to the HU is provided in Section 7. Page 3-2 © 2003, ADC Telecommunications, Inc.

Typical Fiber Optic Cable Routing When routed to the RU outdoor cabinet, the OSP fiber optic cable should be spliced to a connectorized outdoor-rated cable (consisting of individual jacketed pigtails) which is then routed into the outdoor cabinet. The individual pigtails can then be connected directly to the STM optical ports. A connector is provided on the bottom of the RU outdoor cabinet to seal the cable entry point and provide strain relief. The procedure for routing the fiber cable into an outdoor cabinet and for connecting the pigtail leads to the STM is provided in the Digivance 20 Watt Outdoor Remote Unit Installation Instructions (ADCP-75-148). When routed to RU indoor mounting shelf, the OSP cable should be terminated at a fiber distribution panel and spliced to pigtails. Jumper patch cords may then be used to link the STM optical ports to the OSP cable terminations. Whenever possible, a guideway such as the FiberGuide system should be provided to protect the fiber optic patch cords from damage and to prevent excessive bending. The procedure for connecting the OSP optical fibers to an STM mounted in the indoor mounting shelf is provided in the Digivance 20 Watt System Indoor Remote Unit Mounting Shelf Installation Instructions (ADCP-75-149). Page 3-3 © 2003, ADC Telecommunications, Inc. ADCP-75-158 • Preliminary Issue A • June 2003 • Section 3: Host Unit Installation WDM MOUNTING PROCEDURE (OPTIONAL ACCESSORY) A bi-directional wavelength division multiplexer (WDM) system is available as an accessory item for the Digivance system. If the application does not require the use of a WDM system, skip this section and proceed to Section 4. At the HU, the WDM system consists of a WDM host module and a WDM host module mounting shelf. Each host module can support two HU’s and each host module mounting shelf can hold two host modules. A fully loaded host module mounting shelf can therefore support four HU’s. When multiple HU’s require connection to a WDM system, the host module mounting shelf and the HU’s should be mounted in the equipment rack as shown in Figure 3-2. This configuration allows the pigtail leads from the two host modules to be connected directly to the optical ports on any one of the four HU’s. POWERWORX FUSE PANEL HOST UNITS WDM MOUNTING SHELF (WITHOUT MODULES) 18652-A Figure 3-2. Typical WDM and HU Configuration The WDM host module mounting shelf may be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. Four #12-24 screws are provided for securing the mounting shelf to the rack. Use the following procedure to install the host module mounting shelf in the equipment rack and to mount the host modules in the host module mounting shelf: 1. The host module mounting shelf is shipped with the mounting brackets installed for 19inch EIA rack installations. If installing the mounting shelf in a 19-inch EIA rack, proceed to step 5. If installing the mounting shelf in a 19-inch WECO rack, a 23-inch EIA rack, or a 23-inch WECO rack, proceed to step 2. Page 3-4 © 2003, ADC Telecommunications, Inc. ADCP-75-158 • Preliminary Issue A • June 2003 • Section 3: Host Unit Installation 2. Remove both mounting brackets from the mounting shelf (requires Phillips screwdriver) and save screws for reuse. 3. Locate the extra mounting brackets that are provided with the mounting shelf and select the brackets that correspond to the rack type. Each mounting shelf includes extra brackets for installing the mounting shelf in the following rack types: • • • • 19-inch EIA 19-inch WECO 23-inch EIA 23-inch WECO 4. Install the replacement mounting brackets as shown in Figure 3-3. Use the screws removed in step 2 to attach the new brackets to the mounting shelf. 16885-A Figure 3-3. Installing the Replacement Mounting Brackets 5. Position the mounting shelf in the designated mounting space in the rack (per system design plan) and then secure the mounting brackets to the rack using the four #12-24 machine screws provided as shown in Figure 3-4. 6. Install each host module in the mounting shelf (see Figure 3-4). A rail on the side of the module fits into a guide within the mounting. 7. Secure each host module to the mounting shelf by twisting the handle on each quarter-turn fastener 90º. 8. Carefully store the pigtail leads from each host module. The routing and connection procedures for the pigtails are provided in Section 7. Page 3-5 © 2003, ADC Telecommunications, Inc. ADCP-75-158 • Preliminary Issue A • June 2003 • Section 3: Host Unit Installation WDM MOUNTING SHELF WDM MODULE 16888-A Figure 3-4. WDM Host Module Mounting Shelf and WDM Host Module Installation HU MOUNTING PROCEDURE The HU may be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. Both US standard and metric machine screws are included for rack mounting the HU. When loading the HU in a rack, make sure the mechanical loading of the rack is even to avoid a hazardous condition such as a severely unbalanced rack. The rack should safety support the combined weight of all the equipment it holds. In addition, maximum recommended ambient temperature for the HU is 50º C (122º F). Allow sufficient air circulation or space between units when the HU is installed in a multi-rack assembly because the operating ambient temperature of the rack environment might be greater than room ambient. Warning: Wet conditions increase the potential for receiving an electrical shock when installing or using electrically powered equipment. To prevent electrical shock, never install or use electrical equipment in a wet location or during a lightning storm. Note: To insure that all optical connectors remain dust-free during installation, leave all dust caps and dust protectors in place until directed to remove them for connection. Use the following procedure to install the HU in the equipment rack: 1. The HU is shipped with the mounting brackets installed for 19-inch rack installations. If mounting the HU in a 19-inch rack, proceed to step 4. If mounting the HU in a 23-inch rack, proceed to step 2. 2. Remove both mounting brackets from the HU (requires TORX screwdriver with T20 bit) and save screws for reuse. Page 3-6 © 2003, ADC Telecommunications, Inc. ADCP-75-158 • Preliminary Issue A • June 2003 • Section 3: Host Unit Installation 3. Reinstall both mounting brackets so the long side of the bracket is flush with the HU front panel as shown in Figure 3-5. Use the screws removed in step 2 to re-attach the brackets to the HU chassis. REMOVE AND REINSTALL MOUNTING BRACKETS AS SHOWN FOR INSTALLATION IN 23-INCH RACKS 18653-A Figure 3-5. Installing the Mounting Brackets for 23-Inch Rack Installations 4. Position the HU in the designated mounting space in the rack (per system design plan) and then secure the mounting brackets to the rack using the four machine screws provided (use #12-24 or M6 x 10 screws, whichever is appropriate) as shown in Figure 3-6. Note: Provide a minimum of 3 inches (76 mm) of clearance space on both the left and right sides of the HU for air intake and exhaust. 18654-A Figure 3-6.
