ADMONISHMENTS Important safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment. An admonishment identifies a possible hazard and then explains what may happen if the hazard is not avoided. The admonishments — in the form of Dangers, Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of the triangular alert icon (seen below), and are listed in descending order of severity of injury or damage and likelihood of occurrence. Danger: Danger is used to indicate the presence of a hazard that will cause severe personal injury, death, or substantial property damage if the hazard is not avoided. Warning: Warning is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial property damage if the hazard is not avoided. Caution: Caution is used to indicate the presence of a hazard that will or can cause minor personal injury or property damage if the hazard is not avoided.
GENERAL SAFETY PRECAUTIONS 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. 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 transceiver of any digital 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 transceiver or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the adapter or connector. Danger: Do not look into the ends of any optical fiber. Exposure to laser radiation may result. Do not assume laser power is turned-off or the fiber is disconnected at the other end. Danger: 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. Warning: The Digital Chassis and other accessory components are powered by 48 VDC power which is supplied over customer-provided wiring. To prevent electrical shock when installing or modifying the power wiring, disconnect the wiring at the power source before working with uninsulated wires or terminals. Caution This system is a RF Transmitter and continuously emits RF energy. Maintain 3 foot minimum clearance from the antenna while the system is operating. Wherever possible, shut down the HUB before servicing the antenna.

ADCP-75-193 • Issue 1 • December 2005 • Preface
Caution: Always allow sufficient fiber length to permit routing of patch cords and pigtails without severe bends. Fiber optic patch cords or pigtails may be permanently damaged if bent or curved to a radius of less than 2 inches (50 mm). Caution: Exterior surface of the RAN may be hot. Use caution during servicing. Caution: Hazardous voltages are present. The inverter located in the HUB FIR converts 12 VDC to 120 VAC. Use caution when servicing the equipment.
SAFE WORKING DISTANCES The Digivance CXD, when connected to an antenna, radiates radio frequency energy. To comply with Maximum Permissible Exposure (MPE) requirements, the maximum composite output from the antenna cannot exceed 1000 Watts EIRP and the antenna must be permanently installed in a fixed location that provides at least 6 meters (20 feet) of clearance. For the Occupational Worker, safe working distance from the antenna depends on the workers location with respect to the antenna and the number of wireless service providers being serviced by that antenna. Emission limits are from OET Bulletin 65 Edition 97-01, Table 1 A. Should the criteria for safe working distance not be met, the power amplifiers must be turned off at the site where work is to be performed prior to commencing work.

HUB EQUIPMENT The Digivance CXD/NXD Hub equipment consists of a rack assembly housing the Digivance CXD/NXD system hardware. The Hub provides a radio frequency (RF) to optical interface between a wireless service provider (WSP) Base Transceiver Station (BTS) and Radio Access Nodes (RAN) distributed in the network. On the forward path, the Hub takes RF signals from a base station, digitizes the signals, formats the signals into the Sonet protocol, digitally processes the signals and communicates the signals using an optical transceiver to the RAN locations. On the reverse path, the Hub receives signals from multiple RAN locations and converts the Sonet protocol back into RF, conditions the signals, and couples the signals into the receive chain of the BTS. The Hub is a host terminal consisting of the high power attenuators, base station interface modules, a power distribution unit, Ethernet hubs, Hub Reference Modules, and the Digivance CXD/NXD RF and digital hardware sufficient to provide the interface between the BTS electronics of the WSP and the RAN’s. Digivance CXD/NXD Hub equipment is typically housed in a common telecommunications structure with the WSP’s base station electronics, either in the same room, or nearby as shown in Figure 1-1.

An industrial Ethernet hub or Ethernet switch. The Digivance BIM, Digivance HRM, attenuator shelf, attenuators, PDU and the Ethernet hub are sold as accessory items. The following sections define the functionality of the Digivance CXD/NXD base hardware: 1.2.1
Digital CPCI Chassis & Backplane
The Digivance Digital Chassis is a cPCI shelf that houses cooling fans, a CPU, System Interface Module (STF2), Sonet Interface Module (SIF), Reverse Simulcast Module (RSC) and power supplies. The backplane of the Digital Chassis provides the distribution for clock, communication, control data and timing. 1.2.2
RF CPCI Chassis & Backplane
The Digivance RF Chassis is a cPCI shelf that houses the cooling fans, RF transceiver modules, HUC, FBHDC, FSC Modules and the power supplies. The backplane provides the distribution for clock, communication and control data and timing. RF and digital intermediate frequency (DIF) signals are interconnected between modules and chassis’ using the appropriate cabling. 1.2.3
Central Processing Unit (CPU)
The Hub Central Processing Unit (CPU) is a cPCI single board computer running the LINUX operating system. Each Digital Chassis requires one CPU module. There are two Hub CPU types, the Hub Master CPU module and Hub Slave CPU modules. The Hub Master CPU manages its own local hardware as well as controlling the overall system. The Hub Slave CPUs only manage their local hardware. All Slave CPUs communicate to the Hub Master over a network connection. The Hub Master CPU is the main CPU in a CXD/NXD system. There is one Hub Master (HM) CPU per system and it is used to perform the following functions: •
Tenant setup (frequency band, gain, delay)
•
Tenant monitoring (input/output power levels, delay)
•
RF connection setup (BTS & RAN RF connections)
•
Hub equipment placement setup (location of Hub boards, chassis & racks)
•
Provide network services (DNS and DHCP) to all Slave CPUs in system
•
Provide alarm information via SNMP Traps
•
Manage a subset of Hub hardware similar to a Hub Slave CPU
Page 1-4 2005, ADC Telecommunications, Inc.
ADCP-75-193 • Issue 1 • December 2005 • Section 1: Description
With the exception of the Hub Master CPU, the remaining CPUs at the Hub are Slave CPUs. The Slave type CPU provides the following functions: •
Hub slave CPU
•
Manages digital modules within its Digital Chassis (STF2, SIF, RSC)
•
Manages RF modules in the adjacent RF chassis (FBHDC, FSC, HUC)
•
Manages up to two adjacent BTS Interface Modules (BIMs)
•
Communicates information to Hub Master
1.2.4
System Interface (STF2)
The System Interface Card (STF2) provides the communications interface between the CPU and other modules within the Digivance system. The STF2 uses four I2C busses to serially pass functional data between cPCI modules and the cPCI chassis fans for monitoring purposes. The four I2C busses are accessible via the cPCI backplane or via front panel connectors. The STF2 also communicates with the GPS modules found in the Hub Reference Module (HRM). 1.2.5
Sonet Interface (SIF)
The Sonet Interface (SIF) provides the optical interface between the Hub and RAN’s. The SIF has an SFP optical transceiver module installed that provides the optical transmit and receive functions. The SIF has also the following functions: •
Interfaces Digitized RF Signal information to the fiber
•
10BaseT Ethernet for command and control between Hub and the RAN’s.
1.2.6
Small Form-Factor Pluggable Optical Transceiver (SFP)
The Small Form-factor pluggable optical transceiver (SFP) provides the optical interface between the Hub equipment and the RAN hardware. The SFP has a laser transmitter and optical receive detector. The Digivance CXD/NXD system uses industry standard SFP optics compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The pluggable optical transceiver allows a number of configuration options depending on the requirements of the project. The SFP modules are typically factory installed with the SIF or may be purchased separately and may not be installed in the SIF depending on the system as ordered. 1.2.7
Full Band Hub Down Converter (FBHDC)
The Full Band Hub Down Converter (FBHDC) down converts the forward RF carrier to an intermediate frequency (IF) that is then digitized by the Forward Simulcast Card (FSC). Each FBHDC can support up to 15 MHz of contiguous spectrum.

ADCP-75-193 • Issue 1 • December 2005 • Section 1: Description
1.2.8
Forward Simulcast Card (FSC)
The Forward Simulcast Card (FSC) converts the IF signals from the FBHDC to Digital IF (DIF) format. There are eight (8) separate analog-to-digital conversion circuits on one FSC. 1.2.9
Reverse Simulcast Card (RSC)
The Reverse Simulcast Card (RSC) sums the Digital IF (DIF) from up to eight (8) RANs into a single DIF signal that is sent to the appropriate HUC for up conversion to RF. 1.2.10 Hub Up Converter (HUC) The Hub Up Converter (HUC) accepts two (2) Digital IF (DIF) signals from a SIF or RSC. The two (2) DIF signals are converted from digital-to-analog and provided as two (2) separate RF signals (primary and diversity) to the BIM and BTS. 1.2.11 Base Station Interface Module (BIM) The Base Station Interface Module (BIM) is a multi-port transition module used to interface with the tenant’s base station sector. The BIM accepts either duplexed or non-duplexed RF from the base station sector and provides the Hub RF section separate transmit and receive paths. The BIM is controlled via an I2C connection from its respective CPU and provides the following BTS interface functionality: •
Interface to a low power forward BTS RF path.
•
Handles duplexed and non-duplexed signals.
•
Gain adjust for optional reverse path configurations.
1.2.12 Hub Reference Module (HRM) The Hub Reference Module (HRM) generates the RF reference and fiber clocking for distribution within the Hub. In addition, it contains a GPS that generates a 1 PPS (one pulse per second) for distribution to the Digital Chassis modules for delay management. 1.2.13 Ethernet Hub Each Hub rack is equipped with an Ethernet Hub or Ethernet Switch located near the top of the rack. The module is a commercially available unit rated for industrial use. ADC offers a 24 port 120 VAC unit or an optional 24 port –48 VDC unit can be chosen. The Ethernet Hub is used to provide connectivity between Hub CPUs and RAN CPUs through the SIF optical interface as well as providing LAN/WAN connectivity between Hub CPUs and the user. When using the Digivance CXD/NXD SNMP Agent or Digivance Element Management System, the user connects a computer to a port on the Ethernet Hub.

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 Hub equipment 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 5 at the end of this manual) for an RMA (Return Material Authorization) and to reorder if replacement is required.
4
OSP FIBER CABLE INSTALLATION GUIDELINES The outside plant (OSP) fiber optic cables should be routed between the Hub and RAN locations and terminated before the equipment is installed. At the Hub, 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 optical transceivers on each Sonet Interface Module (SIF) to the OSP cable terminations. Whenever possible, a guideway such as the ADC 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 SIF is provided in Section 8. At the RAN, the OSP fiber optic cable should be spliced to a connectorized outdoor-rated cable (consisting of individual jacketed pigtails) which is routed into the RAN cabinet. The individual pigtails can then be connected directly to the SIF optical transceivers. A connector is provided on the bottom of the RAN cabinet to seal the cable entry point and provide strain relief.
5
HUB RACK The Hub rack is a 19-inch four-post rack assembly that is used to mount the Digivance CXD/NXD Hub hardware. The Hub rack secures to the floor and several racks may be mounted together to form a continuous line-up. When multiple racks are installed in the same line-up, position the first rack on the left (as viewed from the front) and build out the line-up working from left to right. Cool air is pulled into each rack from the left and heated air is pushed to the right. An air baffle must be installed between adjacent racks to separate the inlet and outlet airflow. Consult ADC if there are any questions concerning placement of the air baffle. Note: Only trained and qualified personnel should install, replace, or service this equipment. Note: The Digivance CXD/NXD shall be installed and wired by licensed electricians in accordance with the National Electrical Code and local building codes. Electrical service shall accommodate the Hub Base Rack maximum load of 34 amps at –42 VDC. The maximum load means the racks are fully loaded with Digivance CXD/NXD equipment. Note: The HUB shall be bonded and grounded in accordance with National Electrical Code requirements.

ADCP-75-193 • Issue 1 • December 2005 • Section 2: Installation
Figure 2-1. Digital Chassis
Modules and circuit cards are placed into the Digital Chassis and are mated to standard cPCI connectors on the backplane of the chassis. Data and signals are transported over busses on the backplane of the chassis to other modules and ports on the backside of the chassis. Rear connections are made to the Digital Chassis to connect power, route DIF signals to inputs and outputs of respective modules mounted in the chassis, connect the I2C bus to the chassis, input a 1 PPS reference signal, input FAN tachometer readings from the RF Chassis, and distribute 12 VDC to other elements of the system. The Digital Chassis also has a Module/Port status indicator that can be used to trace signals through the system and show activity on the ports. Figure 2-2 shows the back panel connections for the Digital Chassis. The references for the back connectors of the Digital Chassis are shown in the Table 2-2.

6.1 Digital Chassis Mounting Procedure The Digital Chassis requires it to be mounted in a 19-inch EIA or WECO equipment rack. Both US standard and metric machine screws are included for rack mounting the Digital Chassis. When loading equipment 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 safely support the combined weight of all the equipment it holds. In addition, maximum recommended ambient temperature for the Digital Chassis is 50º C (122º F). Allow sufficient air circulation or space between the Digital Chassis and other equipment when installed in a multi-rack assembly because the operating ambient temperature of the rack environment might be greater than room ambient.
Page 2-8 2005, ADC Telecommunications, Inc.
ADCP-75-193 • Issue 1 • December 2005 • Section 2: Installation
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 Digital Chassis in the equipment rack: 1. The Digital Chassis is a cPCI shelf with 19-inch rack installations. 2. Position the Digital Chassis 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). Note: Provide a minimum of 3 inches (76 mm) of clearance space on both the left and right sides of the Digital Chassis for air intake and exhaust.
6.2 Digital Chassis Module Installation The Digital Chassis is an 8 slot chassis. Modules are extracted by pushing outward on the Injection/Extraction Locking (IEL) handles and then drawing the module out of the chassis. They are inserted by aligning the module into desired slot and then pressing inward on the IEL handles until the module is securely seated. The following is specified per the Digivance CXD/NXD system configuration for use in the Digital Chassis: •
Sonet Interface Module
•
Systems Interface Module
•
Reverse Simulcast Module
•
Master Central Processor Module (Hub Master CPU)
•
Slave Central Processor Module (Hub Slave CPU)
The quantity for each module is determined by the network configuration and simulcast ratio. Note that each card slot is not equivalent, thus requiring certain modules to be specifically located within the chassis. Labeling is provided on the chassis for correct installation of the modules. Selection of the modules for this chassis and the Digital Chassis itself should be done in accordance with Table 2-5. The Digital Chassis modules are installed in the front of the unit as shown in Table 2-6. As an example of a standard digital simulcast configuration of one sector to four remotes (1:4 simulcast ratio) the mounting of modules and circuit cards into the Digital Chassis may be done in accordance with Table 2-7.

Figure 2-5. Digital Chassis with 1:4 Simulcast Set-up
The actual configuration may vary depending on the application and the availability of unused cards slots on other Digital Chassis units that may be operating in the system. Before proceeding with the installation of modules, care must be taken to assure that ElectroStatic Discharge (ESD) will not affect components. Slip on an Electro-Static Discharge (ESD) wrist strap and connect the ground wire to an earth ground source such as the grounding stud on the RAN cabinet. Wear the ESD wrist strap while completing any module installation procedure. Warning: Electronic components can be damaged by static electrical discharge. To prevent ESD damage, always wear an ESD wrist strap when handling electronic components.
6.3 Central Processor Unit (CPU) The Hub CPU installs into the Digital Chassis. There are two CPU types used in the CXD/NXD system, Hub Master and Slave CPUs. The Hub Master manages its own local hardware as well as controlling the overall system. The Slave CPUs only manage their local hardware. All Slave CPUs communicate to the Hub Master over a network connection. Figure 2-6 shows the relationship between Master and Slave CPUs.

SFP Installation
If the optical transceivers are factory installed in the SIF, skip this section and proceed to Section 6.7. If the optical transceivers are not factory installed, use the following procedure to install each transceiver: 1. Locate the transceiver socket on the front of the SIF and remove the port cover from the socket. 2. The color of the transceiver extractor handle corresponds to the optical specifications of the SFP and CWDM designations. Select the optical transceiver that is to be used to communicate with the target RAN. Note: For CWDM systems, it is extremely important that the correct wavelength is installed in each SIF. Consult the site fiber plan for details. 3. Remove the transceiver from the anti-static packaging and orient for installation. 4. Insert the optical transceiver into the socket until it locks into place. 5. Replace the optical transceiver dust cap if it was removed for installation. 6. Repeat procedure for each optical transceiver that requires installation.
6.7 Reverse Simulcast Card (RSC) The Reverse Simulcast Card (RSC), shown in Figure 2-11, sums the Digital IF (DIF) from up to eight RANs into a single DIF signal that is sent to the HUC via DIF cables and the chassis rear panel for conversion to RF. The RSC is utilized in the Digital Chassis and is specified as one per tenant per sector per 4 RANs, plus an additional one RSC for RANs 5-7, and an additional one RSC for RAN 8. The references for the RSC are shown in Table 2-11.

7.1 RF Chassis Mounting Procedure The RF Chassis requires it to be mounted in a 19-inch EIA or WECO equipment rack. Both US standard and metric machine screws are included for rack mounting the RF Chassis. When loading equipment 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 RF Chassis is 50º C (122º F). Allow sufficient air circulation or space between the RF Chassis and other equipment when 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.
Page 2-24 2005, ADC Telecommunications, Inc.
ADCP-75-193 • Issue 1 • December 2005 • Section 2: Installation
Use the following procedure to install the RF Chassis in the equipment rack: 1. The RF Chassis is a cPCI shelf with 19-inch rack installations. 2. Position the RF Chassis 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). Note: Provide a minimum of 3 inches (76 mm) of clearance space on both the left and right sides of the RF Chassis for air intake and exhaust.
7.2 RF Chassis Module Installation The RF Chassis is a cPCI shelf with 8 card slots. Modules are extracted by pushing outward on the Injection/Extraction Locking (IEL) handles and then drawing the module out of the chassis. They are inserted by aligning the module into desired slot and then pressing inward on the IEL handles until the module is securely seated. For the RF Chassis, the customer is required to specify various modules as required: •
Forward Simulcast Module (FSC)
•
Hub Up Converter (HUC)
•
Full Band Hub Down Converter (FBHDC)
Modules must be installed into specific slots of the chassis. The RF Chassis can host up to two bands or tenant sectors. Air baffles are inserted into unused slots. Modules are extracted by pushing outward on the extractor release buttons and drawing the module out of chassis. They are inserted by aligning the module into desired slot and pressing inward on the extractor button until the module is securely seated. Refer to Table 2-16 for slot assignments. Slots 1 – 4 are for band or tenant sector 1 and slots 5 – 8 are for band or tenant sector 2. Table 2-16. RF Chassis Slot Assignments SLOT

7.7 RF Chassis Air Baffles The air baffles for the RF Chassis are used in all empty chassis slots. This is done to maintain airflow around the chassis modules. The number of air baffles can be determined by subtracting the number of filled RF Chassis slots from the total available RF Chassis slots, according to Table 2-24.

OPTICAL CONNECTIONS The optical connections with the optical transceivers on the Sonet Interface Card (SIF) are supported by a single dual-fiber optical port. Each optical port consists of a small form factor pluggable (SFP) LC-type optical transceiver. Each transceiver interfaces with single-mode fiber and is color-coded via the extractor handle to identify whether it supports standard range optical budgets, extended range or Coarse Wave Division Multiplexing (CWDM) wavelengths. The modular optical transceivers are accessory items and are field replaceable. The basic optical configuration between the Hub SIF SFP and RAN SIF SFP is shown in Figure 2-22. BASIC CONFIGURATION BETWEEN HUB SIF SFP AND RAN SIF SFP
Figure 2-22. Optical Connections Between Hub and RAN
Page 2-34 2005, ADC Telecommunications, Inc.
ADCP-75-193 • Issue 1 • December 2005 • Section 2: Installation
The optical connections are dependent on whether or not a WDM or CWDM multiplexing equipment (optional accessories) are installed. Additional information can be provided by ADC for different multiplexing options. 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.
8.1 Optical Connections Use the following procedure to connect the optical fibers from a fiber distribution panel to the SFP optical transceiver on each SIF card installed in a system: 1. Obtain a dual-fiber patch cords terminated with Dual-LC connectors that is of sufficient length to reach from the SFP optical transceiver located on a SIF to the fiber distribution panel to the appropriate fiber distribution panel. 2. Attach an identification label or tag next to the connector. 3. Remove the dust caps from the SFP optical transceiver and from the Dual-LC connectors that will be connected to the SFP. 4. Clean each patch cord connector (follow connector suppliers recommendations). 5. Insert the LC connector into the SFP optical transceiver. 6. Route the patch cord from the SIF module to the fiber distribution panel. Note: When using extended range SFP optical transceivers (accessory item) care must be taken to protect the optical receivers. Prior to turning the system one insert a 15 dB attenuator in each optical path. After the optical power has been measured, the attenuator may be resized or removed. Note: The SIF SFP optical adapters when installed in a Digital Chassis are angled to the left. Patch cords should always be routed to the SIF from the left side of the rack. Routing patch cords to the SIF from the right side of the rack may exceed the bend radius limitations for the optics. 7. 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.

GLOBAL POSITIONING SYSTEM (GPS) Each Hub requires one GPS antenna which is associated with the Hub Master CPU. The Hub Master is the manager of the GPS antenna and is responsible for generating a fault if there are any issues with the GPS signal or connection. The GPS antenna is connected to the Hub Reference Module via RF cable to input labeled ‘ANT’. The HRM that is connected to the GPS antenna must be managed by the Hub Master. A CAT5 jumper is connected between the I2C A Bus from the STF2 associated with the Hub Master Node to the I2C input of the HRM connected to the GPS antenna. Using the RS-232 cable supplied connect this HRM to the HUB Master via the STF2 port labeled “GPS”. The GPS antenna is cabled to the Master HRM. The GPS output labeled ‘AUX’ from the Master HRM is cabled to the HRM GPS input labeled ‘ANT’ in the next rack. This continues for all HRMs in the Hub. The last HRMs GPS output is not connected.
10 HUB CABLING ASSEMBLIES See SECTION 3 HUB DIF CABLING for a detailed description of how to configure and cable the Digivance CXD/NXD system for various simulcast configurations. ADC supplies CAT5e cables in lengths of 1, 2, 3, 5, 7, 10, or 15 feet in length for rear port connections between Digital Chassis and RF Chassis. The maximum cable length for DIF signals is 15 feet. DIF cables run from SIF, to RSC, to HUC on the reverse path and from FSC to SIF on the forward path. When the Hub has an LSE chassis, reverse path cables run from SIF, to LSE, to RSC, to HUC. Note To achieve maximum rack layout flexibility, the DIF cables should run directly from source to destination, without routing up to an overhead cable tray. The rack have cable hangers to facilitate direct routes. Note To assure the maximum cable length of 5 meters between ports requires that all modules in a specific simulcast grouping must be located within a group of 3 to 4 adjacent racks.
11 ETHERNET HUB MODULE The Ethernet Hub or Ethernet Switch is used to consolidate Ethernet connections within a Hub rack. The module is a commercially available unit rated for industrial use and is available as an accessory item to the Digivance CXD/NXD system. The standard Ethernet Hub requires 120 VAC power. For projects requiring all DC connections a -48 VDC Ethernet Switch is available as an option. Figure 2-23 shows the layout of a 24 port 120 VAC Ethernet Hub. The references for the Ethernet Hub front panel are shown in Table 2-26.

11.1 Ethernet Hub Installation Use the following procedure to install the Ethernet Hub in the equipment rack: 1. The Ethernet Hub supports 19-inch rack installations. 2. Position the unit 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.
12 HUB REFERENCE MODULE The Hub Reference Module (HRM) is used to: •
Provide RF clock referencing (RF and digital) to the cPCI chassis.
•
Interface to GPS antenna.
•
Provide 1PPS, derived from GPS, to Digital Chassis for delay management.
For every Hubmaster CPU there is only one Master HRM. This unit is the interface to the GPS antenna. The Hub rack managing this Master HRM must be setup to monitor the GPS antenna. Therefore, only the Hubmaster HRM must be monitored for “antenna feedline” fault status. However, all other HRM’s must daisy chained to this GPS input. Starting with the Hubmaster HRM, connect “GPS AUX” of the donor HRM to “GPS IN” of the next HRM in line using an SMA coax cable.
Page 2-37 2005, ADC Telecommunications, Inc.
ADCP-75-193 • Issue 1 • December 2005 • Section 2: Installation
For simulcasting, redundancy, and other functions, HRMs must also share the same clock reference across multiple racks. This is accomplished by daisy-chaining the reference via RJ45 ports on the back of the unit (see figure 2-25). Starting with “9.6 MHz” RJ-45 port “B” of the Hubmaster HRM, connect a crossover CAT-5 cable from port B of each donor HRM to port A of the next HRM in line. Port B will remain open on the last HRM in the chain. Be sure to daisy chain HRMs prior to powering them on or connecting them to I2C. The HRM front panel is shown in Figure 2-24. The references for the HRM front panel are shown in Table 2-27. The HRM rear panel is shown in Figure 2-25. The references for the HRM rear panel are shown in Table 2-28.

12.2 Hub Reference Module Cabling 1. HRM outputs connect to both digital and RF Chassis. 2. The rear panel RJ-45 “Clock Out” connectors are connected to the Digital and RF Chassis 1 HZ REF located on the rear panel. 3. The front panel GPS Input is connected to the GPS antenna or previous HRMs “GPS_AUX” if not HRM master. 4. The front panel GPS Aux is connected to next HRM in adjacent rack (if present). 5. If this is the Master HRM, then the front panel DB-9 connector is connected to the RJ-45 GPS connector on the Hubmaster STF2. If this is not Master HRM, then the closest STF2 is connected. 6. If this is the Master HRM, then the I2C Input/Output is connected to the A-bus of the RF Chassis I2C managed by the Hubmaster CPU. Otherwise the nearest A-bus BIM I2C I/O is used. 7. If multiple HRMs are in use, connect a crossover CAT-5 from port B of each donor HRM to port A of the next HRM in line. Start with “9.6 MHz” RJ-45 port “B” of the Hubmaster HRM. Port B will remain open on the last HRM in the chain. For minimal system impact, be sure to daisy chain HRMs prior to powering them on. Note: The system is setup to automatically detect and configure a daisy-chained HRM configuration. 8. Connect 12VDC to nearest Digital Chassis 12VDC output using power cables provided.

15 HUB EXPANSION KITS In the Digivance CXD/NXD system, the addition of a new band or additional sector for an existing system requires knowing the exact configuration of the existing system and the requirements of the upgrade in service. Information provided by the operator would include number of bands in an existing simulcast cluster, number of additional RAN’s, and desired band load-out per RAN. This information is used to determine the minimum set of new hardware required for the application. ADC sales and customer service will work closely with the operator to understand the desired application and streamline this process. Once the correct kits are selected, their installation is identical to the procedures documented in this manual.

HUB SIMULCAST CONFIGURATION This section describes how to configure the Hub for different simulcast configurations and routing of the Digital IF (DIF) signals between modules and chassis'. Figure 3-1 shows an example configuration of the forward and reverse paths for a single band/tenant sector with a simulcast of 8. Shown is the required number of Sonet Interface (SIF) modules, Reverse Simulcast Card (RSC) modules, and DIF cables. Note that there are 7 different length DIF cables (1, 2, 3, 5, 7, 10, and 15 feet in length) available. The different length DIF cables are required for more efficient cable routing. The diagram in Figure 3-1 can be scaled down accordingly for lower simulcast ratios. Table 31 shows the required hardware for each of the 8 simulcast configurations. The numbering on each of the modules in the block diagram refers to the DIF connections on the rear panel of the Digital Chassis and RF Chassis. The unused connectors on the SIF cards are used to connect an FSC and RSC from a second tenant.

CABLING OF DIGITAL CHASSIS AND RF CHASSIS The rear panels of the Hub Digital Chassis and RF Chassis consist of interconnect ports, allowing for various simulcast configurations. The connections are made via CAT5 cable. In the forward path, the Forward Simulcast Card (FSC) provides 8 identical Digital IF outputs. This allows a maximum simulcast of 8 nodes. Each RAN in the DAS has a corresponding SIF Sonet Interface Card (SIF) in a Hub Digital Chassis. A SIF can support up to two sectors using ports 1/2 and 3/4 on the rear of the cPCI Digital Chassis. To add a RAN to a specific sector, connect an available output (1-8) of the FSC to the corresponding SIF of the desired RAN as shown in Figure 3-2. FSC output 1 is connected to port 1/2 of the SIF. In this example, slots 5-8 house SIF modules and 3 & 4 house RSCs.
Figure 3-2 Hub Simulcast Cabling
The remaining SIF ports (5/6, 7/8) are reserved for reverse path signals. Port 5/6 corresponds to 1/2 (Tenant 1) and 7/8 corresponds to 3/4 (Tenant 2). To complete the reverse path, connect the desired SIF output (5/6 or 7/8) to one of the four inputs on the Reverse Simulcast Card (RSC). In Figure 3-3, the output of the SIF in slot 8 is connected to input 1 of the RSC in slot 4. A single RSC can support 4 RANs. To support larger simulcasts, it is necessary to “cascade” the RSCs. An example diagram of cascaded RSC modules is given in Figure 3-4.

The RSC sums the reverse path Digital IF signals of the simulcast and provides a Digital IF output to the HUC (Hub Up Converter). Connect the output of the RSC (port 9/10) to the proper RJ-45 port on the RF chassis, which corresponds to the HUC of the respective sector as shown in Figure 3-5. The simulcast is complete.

DIF CABLING – BASIC SYSTEM CONFIGURATIONS The Digivance CXD/NXD Hub can be configured in a number of different band/tenant sectors and simulcast scenarios depending on the requirements of the project. To help the user with understanding the basic cabling methods for the Hub Digital Chassis and RF Chassis, the following outlines five different simulcast configurations. These configurations are: 1. Two Band, 1:1 Simulcast 2. Two Band, 2:1 Simulcast 3. Two Band, 4:1 Simulcast 4. Two Band, 6:1 Simulcast 5. Two Band, 8:1 Simulcast

3.4 Simulcast Ratio 6:1 For simulcast ratios between 5:1 and 7:1 two (2) RSC modules per band are required. For each band signals from four RAN’s are digitally summed using a primary RSC and then cascaded to a secondary RSC module. The secondary RSC continues to sum up to an additional three RAN inputs up to a 7:1 ratio. In the example of a 6:1 simulcast ratio, signals from four (4) SIF’s are sent to the primary RSC card. A cable connects the output of the primary RSC to the input of the secondary RSC, where signals from two (2) SIF’s are combined. Figure 3-9 shows a 6:1 simulcast configuration. Note that the combination of six SIF cards and four RSC cards requires two (2) Digital Chassis to support the configuration.

3.5 Simulcast Ratio 8:1 For simulcast ratio of 8:1 requires three RSC modules. For each band signals from four RAN’s are digitally summed using a primary RSC, cascaded to a secondary RSC module that combines signals from three additional RAN’s, which is then cascaded to a third RSC module which combines the signal from an eight RAN. In the example of a 8:1 simulcast ratio, signals from four (4) SIF’s are sent to the primary RSC card. A cable connects the output of the primary RSC to the input of the secondary RSC, where signals from three (3) SIF’s are combined. A cable connects the output of the secondary RSC to the input of a third RSC, where signals from one (1) SIF are combined. Figure 3-10 shows a 8:1 simulcast configuration.
