Primary Distribution Cabinet (Optional) 0

The Primary Distribution Cabinet (PDC) is an optional cabinet that provides a centralized point of demarcation for the various interfaces into and out of the microcell. It contains the components and interfaces necessary to properly connect customer-owned/maintained (and outside service provider-owned/maintained) equipment to the microcell cabinet.

There are two types of PDCs:

� Single PDC (supports one microcell)

� Multiple PDC (supports up to three microcells)

The following interfaces are provided by the PDC:

� AC utility power

� Peripheral bus

� T1/E1 facilities

� POTS line

� External alarm relay contacts

� Maintenance and test ports

� AC generator

� External power backup

To ensure surge protection operation, the PDC must be located within 14.5 meters (50 feet) of the microcell(s) it is serving.

For safety reasons, the PDC should be located within view of the microcell(s) it is serving. If the PDC is not in view of the microcell(s) it is serving, it must be equipped with a circuit breaker lock-out/tag-out feature.

If the PDC is located more than 2.9 meters (10 feet) from the microcell(s) it is serving, a customer-supplied duplex convenience outlet must be provided within 2.9 meters (10 feet) of the microcell.

If a Lucent Technologies PDC is not utilized, refer to page 31 of this document for PDC equivalent requirements.

Network Interface Unit (Optional) 0

The Network Interface Unit (NIU) provides a central point for converting E1 coaxial signaling to balanced signaling required by the microcell. The conversion is from 75-ohm unbalanced to 120-ohm balanced cabling. The NIU also provides coaxial protection for two E1 transmit/receive circuits with expansion to four E1 circuits.

The NIU must be located within 6.1 meters (20 feet) of the PDC that it is serving. If a PDC is not used, the NIU must be located within 6.1 meters (20 feet) of the microcell that it is serving.

The dimensions of the NIU are 254 mm (height) x 254 mm (width) x 95 mm (depth) (10 inches x 10 inches x 3.75 inches).




Power Backup Cabinet (Optional) 0

An optional internal battery is available for the Flexent CDMA Microcell that can provide backup power for ten seconds at full transmit power capability.

If the customer requires a longer power backup capability, Lucent Technologies recommends the use of a Power Backup Cabinet (PBC) from OnLine Power, Inc. The toll-free number for OnLine Power is 1-800-227-8899.

The PBC contains an Uninterruptible Power Supply (UPS) that conditions the utility power under normal operating conditions. If the power utility should fail, the PBC will maintain AC power to the microcell from its internal batteries via a converter. Table 1 provides information on the OnLine Power PBCs.

Table 1. OnLine Power PBC Information

Up to three PBCs can be mounted on a pole.

If another type of backup power cabinet will be used, the customer should refer to page 41 of this document.

Microcell Antenna Architecture and Configurations 1

Architecture 1 The basic architecture of the Flexent CDMA Microcell provides one transmit path and two diversity receive paths for full duplex communication. The RF paths of the microcell can be configured in either simplex or duplex mode. In the simplex mode, each RF path requires an individual antenna. In the duplex mode, the transmit path and the first diversity receive path utilize a common antenna interface port. The second diversity receive path remains a simplex receive and utilizes an individual antenna interface port.

Configurations 1 The configuration options of the Flexent CDMA Microcell are driven by the requirements of the application that it is intended to serve. A combination of microcells can be deployed to provide various cell site configurations.

Table 2 shows the configurations that are supported.

1 1 1 1 3 2

2 1 2 1* or 2 6 4

3 1 3 1* or 3 9 6




The microcell supports the following antenna configurations:

� 3 ports simplex: Tx, Rx0 and Rx1 for diversity

� 2 ports: Tx/Rx0 duplex and Rx1 for diversity

� Built-in antenna, duplexed Tx and Rx dual polarization diversity

� No diversity receive for in-building applications

� Simulcast control and traffic for rural highway applications. (Simulcast refers to the transmission and reception of the same RF information on separate physical antenna faces. The purpose is to direct the capacity of a single microcell to a very specific coverage area.)

The most basic application of the Flexent CDMA Microcell is for a single carrier with an omni-directional or directional antenna.

Figure 3 illustrates the single-sector single-carrier configuration.

Figure 3. Single-Sector Flexent CDMA Microcell Configuration



401-703-340

Multiple microcells with directional antennas can be collocated and controlled by a single Radio Cluster Server (RCS) to form a sectorized cell site. Figure 4 and Figure 5 illustrate examples of this.

AC Power Requirements 6

GeneralRequirements 6

This section describes the AC power requirements for the Flexent CDMA Microcell and Primary Distribution Cabinet (PDC).

All AC wiring and over-current protection must be installed by a licensed electrician and must be provided in accordance with the National Electric Code (NFPA-70) and local electrical codes. An appropriate earth ground connection is required before commercial AC service can be connected.

It is the customer’s responsibility to make arrangements with the local power utility to install the necessary power service, power service entrance equipment and 1-inch PDC input conduit.

For indoor installations, the customer is responsible to provide a power line surge protector on the power input line.

See FLEXENT™ CDMA Microcell Installation Manual (401-703-341, Chapter 3) for detailed instructions on the installation of AC input cables.

AC Input Scenarios 6 The AC input cables can come to the PDC (or equivalent) from four sources:

� Power Backup Cabinet (PBC)

� Power company meter

� Power panel

� AC generator

AC Input Requirements 6

The PDC can have as input either 120/240 VAC, single phase, 60-Hz power or 120/208 VAC, single phase, 60-Hz power. If, however, the customer chooses to use a 120 VAC feed, Lucent Technologies must be consulted to evaluate the application on a case-by-case basis. The AC generator option and the Multiple PDC are not available when using a 120 VAC feed.

The 208/240 VAC input requirements for the PDC (or equivalent) are shown in Table 7.




Table 7. AC Input Power Requirements

Main Circuit Breaker Requirement 7

If a PBC is utilized, the customer must provide an external main circuit breaker and circuit breaker enclosure located between the AC service meter and the PBC. The recommended equipment is a Square D main lug load center (part number QO2L70RB), and Square D circuit breaker (part number QO260). This is a type 3R weatherproof enclosure. Other manufacturers’ equivalent equipment is also acceptable.

In Canada, an external main circuit breaker and circuit breaker enclosure, as described above, are required for all applications. If a PBC is not utilized, the main circuit breaker and enclosure must be located between the AC service meter and the PDC.

Input Voltage 180 to 264 VAC, single phase, 3-wire, 60 Hz(208/240 VAC nominal)

Service 60 Amps

Wire 2 - 8 AWG copper only, 75°C temperature rating



401-703-340

DC Power Requirements 7

GeneralRequirements 7

The Flexent CDMA Microcell can be powered from a +24 VDC source. For this option, the microcell must be provided with an input voltage consistent with a standard +24 VDC battery plant. The maximum ripple and noise allowed on the +24 VDC input is 100 mVp-p from DC to 20 MHz, and 30 mVrms from DC to 20 MHz, measured at the output connector of the DC power source.

DC Regulation and Operating Conditions7

DC regulation and operating conditions are extremely important to ensure that the microcell is properly powered.

! CAUTION:In order to avoid damage to the microcell and ancillary equipment, a power plant should be carefully selected and the following operating conditions must be considered: regulation range, soft start, noise and ripple, transient load response, over-voltage shutdown and over-voltage surge protection.

DC Cable Feeders 7 The wire used for DC feeders must be rated for the environmental condition in which it is used.

DC wire feeders must be sized to limit the round-trip voltage drop between the power system output terminals and the microcell input terminals. The 24 VDC nominal must be present at the microcell terminals under normal conditions, and 20 VDC must be present at the microcell terminals under the most critical operating conditions. Therefore, the location and operating conditions of the DC power plant are extremely important to the operation of the microcell.




Lightning Surge Protection 7

Lightning surge protection is required for outdoor configurations where the DC power source is located more than 7.6 meters (25 feet) from the microcell. Surge protectors must be provided and the DC feeders must be run in properly grounded metal conduit.

Lightning surge protection must be provided such that equipment shall not be degraded or damaged if the feeders are exposed to ten strikes of a surge of 500 V, 500 A 8 µsec/20 µsec pulse waveform.

If all of the cell site equipment and the DC power source are within the “zone of protection” of a higher metallic structure, surge protection on the DC feeders is not required. See Grounding and Lightning Protection Guidelines, Lucent Technologies Network Wireless System Cell Sites (401-200-115) to determine the “zone of protection”.

Grounding of DC Return Conductors 7

The DC return conductors must be bonded to the grounding electrode system at the output of the DC power source. Refer to Grounding and Lightning Protection Guidelines, Lucent Technologies Network Wireless System Cell Sites (401-200-115) for detailed grounding requirements.



401-703-340

PDC and PBC Power Support Considerations 7

7! CAUTION:

Caution must be taken when implementing PBC and PDC configurations.

� When the 650-W PBC is utilized to support one microcell, the heater circuit breaker (CB5) in the PDC must be in the OFF position and the heater wires must be permanently disconnected, since the 650-W PBC is designed to support one microcell without heaters.

� When the 1.3 kW PBC is utilized to support three microcells, the three heater circuit breakers (CB11, CB14, CB15) in the MPDC must be in the OFF position and the heater wires must be permanently disconnected, since the 1.3 kW PBC is designed to support three microcells without heaters.




Use of a PDC Equivalent 7

General 7 The Lucent Technologies PDC is specifically designed as an interface to the Flexent CDMA Microcell. If another manufacturer’s PDC equivalent is used, the following guidelines must be followed.

Power Requirements 7 If another manufacturer’s PDC equivalent is used, it must provide power to the microcell in accordance with Table 8 over all input and output conditions including no load to full load, and low line to high line.

� The DC output must be 24 VDC nominal at the terminals of the microcell.

� The customer must size the cable feeds between the DC source and the microcell to minimize voltage drops.



401-703-340

Grounding and Lightning Protection Bonding Requirements 15

General 15 Flexent CDMA Microcell sites are susceptible to lightning surges due to their association with poles and antennas. Therefore, it is imperative that the cell site be properly grounded and that a low impedance path to earth be provided. The grounding conductors must be as straight and short as possible. No sharp bends or loops are permitted in grounding conductors.

Commercial AC power and T1/E1 facilities are particularly susceptible to lightning surges and must be properly protected. An appropriate surge protection device must be installed at the service entry point and be connected directly to the grounding electrode system.

The antenna cable shield must be bonded at the top and bottom of the vertical run, and also where it comes near the equipment. The metallic support for the antenna must also be bonded to the grounding system. In indoor applications, the antenna cable shield must also be bonded at the hatchplate before entering the building.

All metallic objects within 1.75 meters (6 feet) of the grounded equipment must be bonded to the grounding system.

All Flexent CDMA Microcell sites must be equipped with one or more grounding electrode systems (e.g., buried ring ground, copper clad rod, electrolytic rods, metallic water pipe, etc.). The cell site grounding, including all cabinets and antenna cable shields, must be bonded to the grounding electrode system. It is recommended that two separate, low impedance paths to earth be provided to bond together all grounding systems.

Buried ground conductors must be, as a minimum, #2 AWG bare, solid, tinned copper wire. Exterior ground conductors must be either solid bare tinned copper, or stranded, insulated (insulation to be sunlight-resistant) copper cable. The interior ground cable must be stranded copper with green insulation type THWN or equivalent.

All grounding system material (cable, connectors, buses, etc.) must be of high quality materials that resist deterioration and require little or no maintenance.

Exothermic weld is recommended for grounding connections where practical. All below grade connections must be exothermically welded. Compression type, two-hole (0.75” center) lugs or double crimp “C” taps are also acceptable. The contact area of metal to which connections are made must be prepared to bare bright finish, and coated with an anti-oxidation material before connections are made.




Refer to Grounding and Lightning Protection Guidelines, Lucent Technologies Network Wireless System Cell Sites (401-200-115) and FLEXENT Microcell Cabinet Installation Requirements (ED3R128-10) for detailed requirements related to grounding and lightning protection bonding.

! CAUTION:The equipment warranty can be voided if the guidelines detailed in the National Electric Code NFPA 70, The Standard for Installation of Lightning Protection System (NFPA 780, 1995 edition), Lucent Technologies 401-200-115 and Lucent Technologies Engineering Drawings referenced in this document are not followed.

Verification of the grounding requirements should be performed using checklists SP-3A and SP-3B found in Appendix A of this document.

Grounding Equipment 15

It is the customer’s responsibility to provide and install the following grounding equipment:

� RF and GPS coax cable shield grounding kits (per microcell)

� Grounding electrode system (for details, see 401-200-115)

� Coils of #2 AWG bare, solid tinned copper wire with sufficient length for connection of the main ground bus bar to the grounding electrode system (for details, see Figure 17, Figure 18 and Figure 19)

� Non-metallic cable clips (to secure #2 AWG bare, solid tinned copper wire to the pole or wall at 1.2 meter (48 inch) intervals)

It is recommended that during site preparation, the RF and GPS antenna cable shields be temporarily connected to the grounding electrode system through the #2 AWG bare, solid tinned copper wire mentioned above. During equipment installation, the temporary arrangement will be removed and the antenna cable shields will be connected to the grounding electrode system through the main ground bus bar.

Grounding of Metal Pole 15

If the pole on which the microcell is to be mounted is metallic, it may be used as a down conductor if approval is obtained from the manufacturer or owner of the pole.

The lowermost portion of the metallic pole must be bonded to the grounding electrode system using #2 AWG bare, solid tinned copper cable using exothermic welds.

Antenna Interface Requirements 19


All materials for outdoor antenna cables must be rated for outdoor use. All antenna connections must be waterproofed in accordance with the connector and cable manufacturer’s instructions. All cable runs must be appropriately supported in accordance with the connector and cable manufacturer’s instructions. All antenna jumper cables must be installed in accordance with Lucent Technologies engineering drawings.

Grounding of the antenna cable outer shield must be performed in accordance with the ground kit manufacturer’s instructions and as outlined in Grounding and Lightning Protection Guidelines for Lucent Technologies Network Wireless System Cell Sites (400-200-115).

Lightning surge protection for antennas is provided on top of the Flexent CDMA Microcell.

RF antenna cable ends must be located as specified in the applicable Lucent Technologies engineering drawings. Failure to follow these drawings may result in problems during installation.

Verification of the antenna interface requirements can be performed using Checklist SP-4 found in Appendix A of this document.



401-703-340

RF Antenna Requirements 19

Mounting Options 19 The Flexent CDMA Microcell is primarily intended for use with two RF antennas (one duplex Rx/Tx and one diversity Rx). These antennas may be mounted remotely and cabled to the microcell, or may be integrated within the front panel of the microcell.

In addition, other external antenna configurations are possible, such as:

� Connection to a distributed antenna system

� Connection to two antenna faces simultaneously

� Connections to antennas through an external filter enclosure

� No diversity receive for in-building applications

Integrated Antenna Restrictions for Cellular CDMA 19

When the RF antennas are integrated into the front panel of the microcell, they are mounted at cross angles to provide angular diversity instead of spatial diversity. However, FCC requirements for cellular band transmitters do not allow transmissions to be non-vertically polarized. Therefore the Cellular CDMA Microcell with integrated RF antennas will use simplex transmission, resulting in a total of three RF antennas. The transmit antenna will mount vertically while the two receive antennas are mounted at cross angles.

! CAUTION:The integrated antenna may expose individuals to radio frequency emissions which exceed FCC limits at distances closer than 1.2 meters (4 feet). Installation and maintenance personnel should refer to guidelines in training and user manuals to minimize exposure.

Antenna Specifications 19

All RF antennas must be 50 watts, with a minimum input and output return loss of 14 dB (VSWR less than 1.5:1) at the receive and transmit ports.




In-Building Antenna Considerations 19

There are often many rooms and hallways in any specific building. In order to achieve the best RF coverage in the building, the following items should be considered.

� Omni antennas are recommended for use in the middle of large conference rooms or auditoriums, and in the center of hallway intersections.

� High gain antennas that have 3-dB beamwidth less than, but close to, 180 degrees are recommended for use along the walls of large conference rooms or auditoriums, and at the ends of hallways.

� High gain antennas that have 3-dB beamwidth less than, but close to, 90 degrees are recommended to be used at a corner of a large conference room or auditorium.

� If several floors are to be covered by one antenna, it is recommended that an antenna with horizontal 3-dB beamwidth less than, but close to, 180 degrees be used. It should be noted that each concrete floor may provide another 10- to 15-dB wall loss to the free space propagation loss.

� Leaky coaxial radiators are recommended to provide RF coverage in elevator shafts or building connecting hallways.

GPS Antenna Requirements 19

GPS Antenna Configuration 19

Each Flexent CDMA Microcell requires a GPS signal for synchronizing hand-offs with neighboring cell sites. The GPS antenna can be mounted directly on the microcell, or may be remotely located up to 145 meters (500 feet) from the microcell. GPS repeater amplifiers may be required for the remotely located antenna option. The 1/2-inch foam dielectric has a loss of 4.5-dB/100 feet at 1500 Hz.

When multiple microcells are collocated at a cell site, one GPS antenna can serve up to six microcells through the use of a 1:3 or 1:6 splitter. A 1.2-meter (4 feet) and 9.1-meter (30 feet) cable kit is available to connect the splitter to the microcell. Figure 20 shows three microcells sharing a single GPS antenna signal.

The GPS antenna requires +5 VDC and receives it from the first microcell that it is serving.

Figure 20 GPS Antenna Serving Three Flexent™ CDMA Microcells




Antenna Ordering Information 20

Table 16 lists the ordering information for the three types of GPS antennas.

Table 16 GPS Antennas

Recommended Cable Types 16

It is recommended that high-quality, low-loss cables be used for the GPS antenna connections. The cables should be outdoor (UV) as well as riser (fire-retardant) rated.

Table 17 lists the cable characteristics of two recommended cables.

Antenna Selection Based on Losses 17

The aggregate losses in cables, connectors, splitters and other hardware used to connect the GPS antenna to the microcell should be considered when selecting the GPS antenna.

Table 18 lists the aggregate losses and approximate allowable cable lengths for each type of antenna.

Table 18. Antenna Selection Data

GPS Antenna Installation 18

For detailed installation instructions for the GPS Antenna, refer to Base Station CDMA Reference Frequency Timing Generator and Antenna System Description, Operation, Installation and Maintenance (401-660-128).

Verify GPS Installation and Line of Sight 18

It is highly recommended that a Garmin 45XL (or equivalent) be used to verify the GPS antenna installation and line of sight prior to installing the Flexent CDMA Microcell.

Use Checklist SP-5 (Appendix A) to verify GPS antenna installation prior to beginning the microcell installation.

T1/E1 Facilities Requirements 18

T1/E1 Input Lines 18 The Flexent CDMA Microcell communicates with the 5ESS DCS via a wideband channel called a packet pipe. A packet pipe carries packetized voice and data signals. The pipe consists of DS0 channels on a T1/E1 facility.

The Primary Distribution Cabinet (PDC) serves as the centralized connection point for interfacing all T1/E1 connections at the cell site. The Single PDC provides T1/E1 interface for one microcell and the Multiple PDC provides T1/E1 interfaces for up to three microcells.

For 75 ohm networks, the E1 facility terminates on the Network Interface Unit (NIU). The NIU provides a central point for converting E1 coaxial signaling to balanced signaling required by the microcell. The NIU also provides coaxial protection for two E1 transmit/receive circuits with expansion to four E1 circuits.

The NIU must be located within 6.1 meters (20 feet) of the PDC that it is serving. If an PDC is not used, the NIU must be located within 6.1 meters (20 feet) of the microcell that it is serving.

The Flexent CDMA Microcell accepts two T1 twisted wire pairs from the PDC (or equivalent). The T1 cable input lines should be in place prior to the start of the microcell or PDC installation.

The microcell utilizes one T1/E1 input pair if a dedicated T1/E1 facility is used, and a second facility connection is required for a daisy-chain application.

T1/E1 Daisy-Chaining 18

To make more efficient use of the digital facilities, customers may share a single DS1 facility over six microcells by daisy-chaining them together. The daisy-chaining of Flexent CDMA Microcells is done by running a full DS1 to the first microcell. The line interface unit within the first microcell receives the DS1, but also transmits it on to the next microcell in the chain.

Daisy-chaining can be used in applications where the microcells are closely located, such as a three-sector configuration, or where the microcells are used for in-building distribution and there are several cell sites located within the same building. The maximum distance between daisy-chained microcells without T1/E1 repeaters is 1735 meters (6000 feet).
