FCC ID: F8I-DLC0802A User Manual - Part 3 ADCP-75-150 • Preliminary Issue A • March 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 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 DEMS computer. Figure 2-19. NOC/NEM Interface Typical Commands 11 SPECIFICATIONS Refer to Table 2-6 for the Digivance 800 MHz 20 Watt System nominal specifications. All specifications apply after a five minute warm-up period.

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. OUTDOOR CABINET OSP FIBER CABLE INSTALLATION GUIDELINES The outside plant (OSP) fiber optic cables should be routed between the HU and RU outdoor cabinet and terminated before the equipment is installed. A diagram of a typical OSP 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. Jumper 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. ADCP-75-150 • Preliminary Issue A • March 2003 • Section 3: Host Unit Installation HOST SITE HOST UNIT SPLICE FIBER DISTRIBUTION PANEL PATCH CORD PIGTAIL OUTSIDE PLANT CABLE REMOTE SITE STM REMOTE UNIT CABINET INDOOR/OUTDOOR CABLE WITH PIGTAIL LEADS SPLICE ENCLOSURE 16889-A Figure 3-1. Typical OSP Cable Routing At 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 routed into the 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 the 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). Page 3-3 © 2003, ADC Telecommunications, Inc. ADCP-75-150 • Preliminary Issue A • March 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 LRCS. If the application does not require the use of a WDM, skip this section and proceed to Section 4. At the HU, the WDM system consists of a WDM module and a WDM mounting shelf. Each WDM module can support two HU’s and each WDM mounting shelf can hold two WDM modules. A fully loaded WDM mounting shelf can therefore support four HU’s. When multiple HU’s require connection to a WDM, the WDM 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 WDM 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 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 WDM mounting shelf in the equipment rack and to mount the WDM modules in the WDM mounting shelf: 1. The WDM mounting shelf is shipped with the mounting brackets installed for 19-inch 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-75-150 • Preliminary Issue A • March 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 rack types specified in step 1. 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 WDM 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 #1224 machine screws provided as shown in Figure 3-4. 6. Install each WDM 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 WDM module to the mounting shelf by twisting the handle on each quarterturn fastener 90º. 8. Carefully store the pigtail leads from each WDM module. The routing and connection procedures for the pigtails are provided in Section 7. Page 3-5 © 2003, ADC Telecommunications, Inc. ADCP-75-150 • Preliminary Issue A • March 2003 • Section 3: Host Unit Installation WDM MOUNTING SHELF WDM MODULE 16888-A Figure 3-4. WDM Mounting Shelf and WDM 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-75-150 • Preliminary Issue A • March 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. HU Rack Mount Installation Page 3-7 © 2003, ADC Telecommunications, Inc. ADCP-75-150 • Preliminary Issue A • March 2003 • Section 3: Host Unit Installation CHASSIS GROUND CONNECTION A stud is provided on the rear side of the chassis for connecting a grounding wire to the chassis. Use the following procedure to connect the grounding wire to the chassis and to route the grounding wire to an approved earth ground source. 1. Obtain a length of #18 AWG (1.00 mm) insulated stranded copper wire for use as a chassis grounding wire. 2. Terminate one end of the wire with a ring terminal. 3. Locate the chassis ground stud at the rear of the HU as shown in Figure 3-7. 16169-A Figure 3-7. Chassis Ground Stud 4. Attach the ring end of the wire to the chassis ground stud (see Figure 3-7). 5. Route the free end of the chassis grounding wire to an approved (per local code or practice) earth ground source. 6. Cut the chassis grounding wire to length and connect it to the approved ground source as required by local code or practice. Note: Be sure to maintain reliable grounding. Pay particular attention to ground source connections. COAXIAL CABLE CONNECTIONS The RF interface between the HU and the BTS is supported through two type N female connectors mounted on the HU front panel. One connector provides the coaxial cable connection for the forward path (downlink) signal and the other connector provides the coaxial cable connection for the reverse path (uplink) signal. In most installations, it is usually necessary to insert some attenuation in the forward path link between the HU and the BTS. A signal level that is greater than –10 dBm will overdrive and Page 3-8 © 2003, ADC Telecommunications, Inc. ADCP-75-150 • Preliminary Issue A • March 2003 • Section 3: Host Unit Installation possibly damage the HU receiver. Refer to Section 4, Subsection 2.3, before completing the forward path connection between the BTU and HU. If the Conditioning Panel or Duplexing Panel is required, refer to the Digivance 800 and 1900 MHz Interface Panels User Manual (ADCP-75-147) for the installation procedures. The HU should be mounted as close as possible to the BTS to minimize cable losses. Use the following procedure to route and connect the forward and reverse path coaxial cables to the HU: 1. Obtain the required lengths of high performance, flexible, low loss 50-ohm coaxial communications cable (RG-400 or equivalent) for all coaxial connections. 2. Route the forward and reverse path coaxial cables between the HU and the BTS interface (per system design plan) and cut to the required length. Allow sufficient slack for dressing and organizing cables at the HU and for installing an external attenuator in the forward path link. 3. Terminate each cable with a type N male connector following the connector supplier’s recommendations. 4. Connect the forward path cable to the FORWARD RF IN connector on the HU front panel as shown in Figure 3-8. Note: Do not connect the forward path cable at the BTS until the composite forward path RF signal level is measured and the amount of attenuation required is determined. REVERSE RF OUT CONNECTOR (REVERSE PATH) TYPE-N MALE CONNECTOR FORWARD RF IN CONNECTOR (FORWARD PATH) 18655-A Figure 3-8. Forward and Reverse Path Coaxial Cable Connections 5. Connect the reverse path cable to the REVERSE RF OUT connector on the HU front panel (see Figure 3-8). 6. Dress and secure cables at the HU. 7. Complete all remaining coaxial connections as specified in the system design plan. Page 3-9 © 2003, ADC Telecommunications, Inc. ADCP-75-150 • Preliminary Issue A • March 2003 • Section 3: Host Unit Installation OPTICAL CONNECTIONS The optical interface between the HU and the RU is supported by two optical ports. Each optical port consists of an SC optical adapter which is mounted on the HU front panel. Port 1 provides the optical fiber connection for the forward path (downlink) signal. Port 2 provides the optical fiber connection for the reverse path (uplink) signal. The optical connections are dependent on whether or not a WDM (accessory) or CWDM (accessory) module is installed. If the installation does not include a WDM, proceed to Section 7.1 for the optical connections procedure. If the installation includes a WDM, proceed to Section 7.2 for the optical connections procedure. If the installation includes a CWDM, refer to the Digivance System Coarse Wavelength Division Multiplexer User Manual (ADCP-75-142) for the optical connection procedure. Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transmitter of any unit or exposure to laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating transmitter or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the connector. 7.1 Optical Connections Without WDM Use the following procedure to connect the optical fibers when a WDM is not installed with the HU: 1. Obtain two patch cords that are of sufficient length to reach from the HU to the fiber distribution panel. 2. Designate one of the patch cords as the forward path link and the other as the reverse path link and attach an identification label or tag next to the connector. 3. Remove the dust caps from the HU optical ports and from the patch cord connectors that will be connected to the HU. 4. Clean each patch cord connector (follow connector supplier’s recommendations). Note: To protect the optical receivers, insert a 15 dB attenuator in each optical path. After the optical power has been measured, the attenuator may be resized or removed. 5. Insert the connector into the appropriate optical port as shown in Figure 3-9 and as specified by the following: Port 1 - Forward path patch cord Port 2 - Reverse path patch cord 6. Route the patch cords from the HU to the fiber distribution panel. Note: The HU optical adapters are angled to the left. Therefore, patch cords should always be routed to the HU from the left side of the rack. Routing patch cords to the HU from the right side of the rack may exceed the bend radius limitations for the optical fiber. Page 3-10 © 2003, ADC Telecommunications, Inc.

Identify the OSP cable optical fiber terminations that correspond to the RU. 8. Designate one of the OSP fibers as the forward path link and the other as the reverse path link and attach an identification label or tag next to the connector. 9. Remove the dust caps from the OSP cable optical fiber adapters and from the patch cord connectors. 10. Clean each patch cord connector (follow connector supplier’s recommendations) and then mate the connector with the appropriate OSP cable adapter. 11. Store any excess patch cord slack at the fiber distribution panel. 7.2 Optical Connections With WDM Use the following procedure to connect the optical fibers when a WDM module is installed with the HU: 1. Obtain a patch cord that is of sufficient length to reach from the WDM module to the fiber distribution panel. 2. Remove the dust cap from one of the two optical ports on the WDM module and from the patch cord connector that will be connected to the WDM module. Note: Each WDM module can support two separate HU’s. The WDM module ports are numbered from 1 through 6 as shown in Figure 3-10. Ports 1 through 3 are used for HU #1 and Ports 4 through 6 are used for HU #2. Page 3-11 © 2003, ADC Telecommunications, Inc.

Note: To protect the optical receivers, insert a 15 dB attenuator in each optical path. After the optical power has been measured, the attenuator may be resized or removed. 4. Insert the connector into one of the WDM module’s optical ports (port 1 or 4). 5. Route the patch cord from the WDM to the fiber distribution panel. 6. Identify the OSP cable optical fiber termination that corresponds to the RU. 7. Remove the dust cap from the OSP cable optical adapter and from the patch cord connector. 8. Clean the patch cord connector (follow connector supplier’s recommendations) and then mate the connector with the appropriate OSP cable adapter. 9. Store any excess patch cord slack at the fiber distribution panel. 10. Remove the dust caps from the HU optical ports and from the WDM pigtails that will be connected to the HU. 11. Clean each pigtail connector (follow connector supplier’s recommendations) and then insert the connector into the appropriate optical port on the HU as shown in Figure 3-9 and as diagramed in Figure 3-10. Note: The HU optical adapters are angled to the left. Therefore, pigtails should always be routed to the HU from the left side of the rack. Routing pigtails to the HU from the right side of the rack may exceed the bend radius limitations for the optical fiber. Page 3-12 © 2003, ADC Telecommunications, Inc. ADCP-75-150 • Preliminary Issue A • March 2003 • Section 3: Host Unit Installation CONTROLLER AREA NETWORK CONNECTIONS Controller area Network (CAN) interface connections between multiple HU’s are supported by a pair of RJ-45 jacks. One of the jacks is designated as the NET IN port and the other jack is designated as the NET OUT port. The CAN interface allows up to 24 HU’s to be connected together (in daisy-chain fashion) and controlled through a single Digivance EMS computer. A one meter long cable is provided with each HU for CAN connections. Use the following procedure to connect CAN interface cables between multiple HU’s: 1. Connect one end of the CAN interface cable (provided with the HU) to either the NET IN or NET OUT port on HU #1 as shown in Figure 3-11. 18658-A RJ-45 CONNECTOR DETAIL Figure 3-11. Controller Area Network Connections 2. Route the CAN interface cable to HU #2 and connect the cable’s free end to the port that is the logical opposite of the network port the cable was connected to at HU #1. Note: If connected to a NET OUT port at HU #1, connect to the NET IN port at HU #2. If connected to a NET IN port at HU #1, connect to a Net OUT port at HU #2. 3. If a third HU will be connected to the network, connect a second CAN interface cable to the remaining network port on HU #2. 4. Route the second CAN interface cable to HU #3 and connect the cable’s free end to the port that is the logical opposite of the port that the cable is connected to at HU #2. 5. Repeat steps 3 and 4 for each additional HU that is added to the network up to a total of 24 HU’s. A diagram of typical CAN interface connections is shown in Figure 3-12.
