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

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 HU is powered by 48 VDC power which is supplied over customer-provided

wiring. To prevent electrical shock when installing or modifying the HU power wiring, disconnect the wiring at the power source before working with uninsulated wires or terminals.

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).

1 INTRODUCTION

This section provides basic description, application, and configuration information about the

Digivance SCS system. Throughout this publication, all items referenced as “accessory items” are not furnished with the basic product and must be purchased separately.

2 SCS SYSTEM OVERVIEW

The Digivance Long Range Coverage Solution (LRCS) system is an RF signal transport system that provides long-range RF coverage to areas where it is impractical to place an Enhanced Base

Transceiver Station (EBTS) at the antenna site. High real estate costs and community restrictions on tower and equipment locations often make it difficult to install the EBTS at the same location as the antenna. The LRCS system overcomes equipment placement problems by hubbing base stations at a central location and placing antennas at remote locations with minimal real estate requirements. The LRCS system transports RF signals to remote locations to expand coverage into areas not receiving service or to extend coverage into difficult to reach areas such as canyons, tunnels, or underground roadways.

The SCS system provides the same functionality as the LRCS system but incorporates a low profile, low power, low cost remote unit. The SCS system remote unit complements the high power remote unit used with LRCS systems. The primary application includes urban areas where multiple, strategically placed, low power remote units provide better coverage than high power remote units.

2.1

Basic SCS System Components

The basic components of a typical Digivance SCS system and their function are shown in

Figure 1-1 . A basic SCS system consists of a Host Unit (HU) and a Remote Unit (RU). The HU consists of a rack-mountable chassis that is designed for use in an indoor environment. The RU consists of a sealed enclosure that is designed for use in an outdoor environment. Control and monitoring functions are provided by the Digivance Element Management System (EMS).

2.2

Enhanced Base Transceiver Station Interface

The HU is interfaced with an EBTS over coaxial cables as shown in Figure 1-2 . The EBTS provides the RF channel inputs and outputs for a designated sector. In the forward path, the HU receives two RF inputs from the EBTS. The HU digitizes the RF spectrum and then converts it to digital optical signals for transport to the RU. In the reverse path, the HU receives digital optical signals from the RU. The HU converts the digital optical signals back to two RF outputs which are supplied to the EBTS over the coaxial cable interface.

Subscriber Unit Interface

The RU interfaces with the subscriber units (cell phones) through an antenna. In the reverse path, the RU receives RF spectrum from each subscriber unit (see Figure 1-1 ). The RU digitizes the RF spectrum and then converts it to digital optical signals for transport to the HU over the optical fiber link. In the forward path, the RU receives digital optical signals from the HU. The

RU converts the optical signals to RF spectrum for transmission to the subscriber units. The RU is connected to an antenna (not provided) which transmits and receives the subscriber unit RF spectrum.

2.4

Local Management Interface

Communications with an individual Digivance system is supported through a local management interface capability as shown in Figure 1-3 . A local management interface requires a PC-type computer loaded with the Digivance Element Management System (EMS) software. EMS provides the various control and monitoring functions required to locally manage a Digivance system. The EMS computer connects directly to the HU through the computer’s RS-232 port.

Operation is implemented through the EMS Graphical User Interface (GUI). The GUI consists of a series of screens from which the user selects the desired option or function. An RS-232 service port is provided on both the HU for connecting the EMS computer.

Network Operations Center Interface

Communications between a Network Operations Center (NOC) and a networked group of multiple Digivance systems is supported by a NOC interface capability as shown in Figure 1-5 .

To support the NOC interface, a PC-type computer loaded with the Digivance Element

Management System (EMS) software is required. EMS provides the various control and monitoring functions required to remotely manage multiple Digivance systems through the

NOC interface.

A Controller Area Network (CAN) port is provided on each HU. Up to twenty-four HU’s may be linked together through the CAN interface and controlled by the same EMS computer. All the networked HU’s and the associated RU’s may be managed by connecting the EMS computer to one HU. The EMS computer provides an RS-232 port (#1) to support the interface with the networked HU’s.

The NOC can be linked to the EMS computer through a T1 system, DS0 with RS232 conversion, or some other medium. The EMS computer provides an RS-232 ASCII interface port (#2) to support the interface with the NOC.

At the NOC, control and monitoring of the networked Digivance systems is implemented through a Network Element Manager (NEM) interface which requires only a VT100 terminal/ emulator for operation. The NEM interface language consists of simple ASCII text strings. All communications are input as either SET or GET commands which result in ASCII text string responses from the specified system or systems.

SNMP Interface

Communications between an external Simple Network Management Protocol (SNMP) Manager and a networked group of multiple Digivance systems is supported by an SNMP interface capability as shown in Figure 1-6 . To support the SNMP interface, a PC-type computer loaded with both the Digivance Element Management System (EMS) software and the SNMP Proxy

Agent software is required. The EMS and SNMP Proxy Agent software plus the associated

Management Information Base (MIB) provide the various control (Set) monitoring (Get) and trap functions required to remotely manage multiple Digivance systems using an SNMP

Manager.

A Controller Area Network (CAN) port is provided on each HU. Up to twenty-four HU’s may be linked together through the CAN interface and controlled by the same EMS computer. All the networked HU’s and the associated RU’s may be managed by connecting the EMS computer to one HU. The EMS computer provides an RS-232 port (#1) to support the interface with the networked HU’s.

The SNMP Manager may be linked with the EMS computer through a Local Area Network

(LAN). The EMS computer provides an Ethernet port to support the interface with the LAN.

The SNMP Proxy Agent supports two versions of the SNMP protocol: SNMPv1 and SNMPv2c.

A facility to Register/Unregister an SNMP Manager for receiving traps is also supported by the

SNMP Proxy Agent. The SNMP Manager is an option and must be ordered separately from the EMS software.

3 SYSTEM FUNCTIONS AND FEATURES

This section describes various system level functions and features of the Digivance system.

3.1

Fiber Optic Transport

In a typical Digivance LRCS system, the HU is connected to the RU over two single-mode optical fibers. One fiber is used to transport the forward path optical signal. The other fiber is used to transport the reverse path optical signal. Because the optical signal is digital, the input and output RF signal levels at the HU or the RU are not dependent on the level of the optical signal or the length of the optical fiber. A diagram of the fiber optic transport system for a typical Digivance LRCS system is shown in Figure 1-7 .

Figure 1-7. LRCS System Fiber Optic Transport - Typical

The maximum length of the optical links is dependent on the loss specifications of the optical fiber, the losses imposed by the various connectors and splices, and the RF modulation protocol response timing limitations. The basic system provides an optical budget of 25 dB (typical) when used with 9/125 single-mode fiber.

In SCS applications, the forward path and reverse path optical signals from an HU/RU pair are combined onto a single optical fiber. This is accomplished by using a passive bi-directional

Wavelength Division Multiplexer (WDM) system. The optical wavelengths used in the

Digivance system are 1550 nm for the forward path and 1310 nm for the reverse path. Because different wavelengths are used for the forward and reverse paths, both signals can be combined on a single optical fiber. A WDM module (accessory) is installed with the HU at the host site

The SCS RU, which is equipped with an internally mounted WDM, is installed at the remote site as shown in Figure 1-8 .

3.2

Control and Monitoring Software

The EMS software and the SNMP Proxy Agent software provide control and monitoring functions for the Digivance system through the local, NOC, and SNMP interfaces. The EMS software package supports the local and NOC interfaces but does not include the SNMP Proxy

Agent software which must be ordered separately. Both the EMS and the SNMP Proxy Agent software are required to support the SNMP interface. All software files are provided on CD-

ROM’s. Software installation consists of copying the software files from the CD-ROM’s to a designated directory on the hard-drive of the EMS computer.

The EMS software provides the capability to provision and configure the Digivance system for operation. This includes selecting a site name, setting alarm thresholds, and setting forward and reverse path RF gain adjustments. The EMS software also provides the capability to get alarm messages (individual or summary), obtain data measurements, and to upgrade the HU/RU system software. All control and monitor functions (except software upgrade which is not supported by the NOC/NEM and SNMP interfaces and HU/RU pair site number assignment which is not supported by the SNMP interface) may be implemented using the NOC/NEM interface, the SNMP interface, or the EMS software GUI.

3.3

Fault Detection and Alarm Reporting

LED indicators are provided on the front panel of the HU and on the underside of the RU to indicate if the system is normal or if a fault is detected. In addition, normally open and normally closed alarm contacts (for both major and minor alarms) are provided at the HU for connection to a customer-provided external alarm system. All alarms can also be accessed through the

NOC/NEM interface, SNMP manager, or the EMS software GUI.

3.4

Powering

The HU is powered by ±24 or ±48 VDC and must be hard-wired to a local DC power source through a fuse panel. A screw-down terminal strip is provided on the rear side of the HU for the power connections.

The RU is powered by 90 to 265 VAC (nominal 120 or 240 VAC), 47 to 63 Hz power. On an optional basis, the RU may be powered by 60 to 89 VAC, 47 to 63 Hz power. A connector is provided on the underside of the RU for the AC power connections. A 3-wire AC power cable rated for outdoor use is included with the RU. The stub end of the cable must be hard-wired to the AC power source.

3.5

Equipment Mounting and Location

The HU consists of a rack-mountable chassis assembly that is designed for mounting in a non-

condensing indoor environment such as inside a wiring closet or within an environmentally-

controlled cabinet. The HU is usually installed within 20 feet of the EBTS and may be mounted in either a 19- or 23-inch, WECO or EIA, equipment rack.

The RU consists of a sealed aluminum enclosure designed for mounting in either an indoor or

outdoor environment. The RU may be mounted from a pole or the exterior side of a building

with the standard mounting bracket or from a strand with an accessory bracket.

4 DUAL-BAND REMOTE UNIT SCS SYSTEMS

Sections 1 through 3 described the functions and features of a typical SCS system equipped with one HU and the single-band RU. Each single-band RU is equipped with the electronics to support one frequency band. If it is necessary so support two frequency bands (such as 800/900

MHz SMR and 1900 MHz) at the same remote location, a dual-band RU can be deployed. A dual-band RU provides the electronic and optical functionality of two single-band RU’s except that all the electronic and optical components are housed within a single enclosure.

A dual-band SCS system consists of two standard host units and a dual-band RU that are linked together over two optical fibers. At the hub site, each HU is connected to a separate EBTS facility. The dual-band RU supports the frequency bands (such as 800/900 MHz SMR and 1900

MHz) associated with the two connected HU’s. Each HU and the corresponding RU electronics function independently of each other and may be managed separately using the same element manager system (EMS). Figure 1-9 shows a typical SCS system equipped with a dual-band RU.

One fiber is used to transport the forward/reverse path optical signals for one SCS system. The other fiber is used to transport the forward/reverse path optical signals for the other SCS system.

1 INTRODUCTION

This section describes the basic components of a typical Digivance SCS system including the

Host Unit (HU), Remote Unit (RU), element management system, and accessories. The system specifications are provided in a table at the end of this section.

2 HOST UNIT

Two versions of the HU are available. The rear access HU, shown in Figure 2-1 , is used with

800/900 MHz SMR systems. The front access HU, also shown in Figure 2-1 , is used with 800 and 1900 MHz systems. Connection points for the RF, optical, and alarm cables are provided on the rear side of the rear access HU and on the front side of the front access HU. Both HU versions provide the following basic functions:

• Provides a limited adjustable RF interface with the BTS.

• Provides a fiber optic interface with the RU.

• Digitizes the two forward path composite RF signals.

• Converts the two digitized forward path RF signals to a digital optical signal.

• Converts the digitized reverse path optical signal to two digitized RF signals.

• Converts the two digitized reverse path RF signals to two composite RF signals.

• Sends alarm information to an external alarm system through relay contact closures

• Provides an RS-232 interface for connecting the EMS computer.

• Provides a CAN interface for networking multiple HUs.

2.1

Primary Components

The HU consists of an electronic circuit board assembly and a fan assembly that are mounted within a powder-paint coated sheet metal enclosure. The enclosure provides a mounting point for the circuit board and fan assemblies and controls RF emissions. The only user-replaceable component is the fan assembly. The HU is designed for use within a non-condensing indoor environment such as inside a wiring closet or cabinet. The front access HU is also equipped with a front cable management tray and vertical cable guides.

2.2

Mounting

The HU is intended for rack-mount applications. A pair of reversible mounting brackets is provided that allow the HU to be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. When the rear access HU is installed, the front panel of the HU is flush with the front of the rack. When the front access HU is installed, the front panel of the HU is flush with the front of the rack and the cable management tray extends 3.9 inches (99 mm) beyond the front panel. Screws are provided for securing the HU to the equipment rack.

The HU detects and reports various internal and external faults including host unit fault, optical fault, power fault, temperature fault, and RF fault. Various front panel Light Emitting Diode

(LED) indicators turn from green to red or yellow if a fault is detected. A set of alarm contacts

(normally open and normally closed) are provided for reporting an alarm to an external alarm system when a fault is detected. Both major alarm (system operation seriously affected) and minor alarm (system operation not affected or only slightly degraded) contacts are provided.

Fault and alarm information may also be accessed locally through the EMS software GUI or remotely through the NOC/NEM interface or SNMP interface. An alarm history file is maintained by the EMS software so that a record is kept of all alarms as they occur. This is useful when an alarm is reported and cleared before the reason for the alarm can be determined.

The status of the HU, the alarm state (major or minor), and other alarm information is summarized and reported over the service interface, the CAN interface, and the optical interface to the RU. In addition, the status of the RU is transmitted to the HU over the optical interface and reported over the service interface and the CAN interface.

Page 2-3



2.4

RF Signal Connections

The RF signal connections between the rear access HU and the EBTS are supported through four N-type female connectors. Two connectors are used for the forward path RF signals and two connectors are used for the reverse path RF signals.

The RF signal connections between the front access HU and the EBTS are supported through two N-type female connectors. One connector is used for the forward path RF signal and the other connector is used for the reverse path RF signal.

In most installations, it is usually necessary to install external attenuators to support the RF interface between the HU and the EBTS. The HU should be as close as possible to the EBTS to minimize coaxial cable losses.

2.5

RF Signal Level Adjustments

The HU is equipped with several attenuators for adjusting the signal levels of the forward and reverse path RF signals. The attenuators provide an attenuation adjustment range of 0 to 31 dB and can be set in 1 dB increments. The attenuators are software controlled and are adjusted through the EMS software GUI, NOC/NEM interface, or SNMP interface.

The host forward path attenuators adjust the level of the input RF signal(s) to the HU. Using the forward path attenuator, an input signal with a nominal composite signal level of –9 dBm to

–40 dBm can be adjusted to produce maximum power output. Additional external attenuation

is required if the input signal level is greater than –9 dBm.

Note: The optimum composite RF input signal level for 800/900 MHz SMR systems is

–20 dBm.

The host reverse path attenuators adjust the level of the output RF signal(s) from the HU and will add from –1 dB of gain (attenuator set to 31 dB) to +30 dB of gain (attenuator set to 0 dB) to the RF output signal(s) at the HU.

2.6

Propagation Delay

The HU forward and reverse path propagation delays may be adjusted in 0.1

µsec increments within a range of 0 to 63

µs. The propagation delay is software controlled and may be adjusted through the EMS software GUI, NOC/NEM interface, or SNMP interface.

2.7

Optical Connection

Optical connections between the HU and the RU are supported through two optical ports equipped with UPC/SC (flat) connectors. One port is used for the forward path optical signal connection and the other port is used for the reverse path optical signal connection.

Page 2-4



2.8

Controller Area Network Interface Connection

Controller Area Network (CAN) interface connections between multiple HUs are supported by a pair of RJ-45 jacks. One of the jacks is designated as the network IN port and the other jack is designated as the network OUT port. The CAN interface allows up to 24 HUs to be connected together (in daisy-chain fashion) and controlled through a single EMS computer.

2.9

Service Interface Connection

The service interface connection between the HU and the EMS computer is supported by a single DB-9 female connector. The service connector provides an RS-232 DTE interface. When multiple HUs are networked together, the supporting EMS computer may be connected to the service connector of any one of the networked HUs.

2.10 Powering

The HU is powered by

± 21 to ± 60 VDC power (nominal

± 24 or ± 48 VDC)

. The power is fed to the HU through a screw-down type terminal strip located on the rear side of the unit. Power to the HU must be supplied through a fuse panel such as the PowerWorx GMT Series Fuse Panel

(available separately). The power circuit for each HU must be protected with a 3 Amp GMT fuse. An On/Off switch is provided on the HU front panel.

2.11 Cooling

Continuous airflow for cooling is provided by dual fans mounted on the right side of the HU housing. A minimum of 3 inches (76 mm) of clearance space must be provided on both the left and right sides of the HU for air intake and exhaust. An alarm is generated if a high temperature condition (>50º C/122º F) occurs. The fans may be field-replaced if either fan fails.

2.12 User Interface

The HU user interface consists of the various connectors, switches, terminals, and LEDs that are provided on the HU front and rear panels. The rear access HU user interface points are indicated in Figure 2-2 and described in Table 2-1 . The front access HU user interface points are indicated in Figure 2-3 and described in Table 2-2 .

3 REMOTE UNIT

The RU is available in either a single-band or a dual-band version. Both versions of the RU provide the following basic functions:

• Convert the digitized forward path optical signals to digitized RF signals.

• Convert the digitized forward path RF signals to composite RF signals.

• Digitize the reverse path composite RF signals.

• Convert the digitized reverse path RF signals to digitized optical signals.

• Provide an RF interface (antenna port) for the remote antenna(s).

• Provide an optical interface for the HU.

• Transport alarm, control, and monitoring information to the HU via the optical interface.

• Accept AC power input.

• Provide a visual indication of unit status

3.1

Primary Components

Depending on the version, the RU consists of either two or four electronic assemblies mounted within an environmentally-sealed cast-aluminum enclosure. The Spectrum Transport Module

(STM) provides optical-to-RF and RF-to-optical conversion and digitizing functions; alarm, control, and monitoring functions; power conversion functions; and RF filtering and interface functions. The Linear Power Amplifier (LPA) works in conjunction with the STM to amplify

Page 2-9


ADCP-75-187 • Preliminary Issue 1B • November 2005 • Section 2: DESCRIPTION the forward path RF signal. The aluminum enclosure provides a mounting point for the electronic assemblies, controls RF emissions, seals out dirt and moisture, and provides passive cooling. The electronic assemblies are not user replaceable or accessible. All connectors and indicators are mounted on the bottom of the RU enclosure for easy access.

The single-band version of the RU consists of one STM and one LPA mounted within the same enclosure. The dual-band version, shown in Figure 2-4 , consists of two STM’s and two LPA’s mounted within the same enclosure. The dual-band version makes it possible to support two separate frequency bands with a single RU.

20568-C

Figure 2-4. Dual-Band Remote Unit

3.2

Mounting

The RU may be mounted on a flat vertical surface (such as the side of a building) or on a utility pole. A combination wall/pole mounting bracket is provided with each unit. A separate strandmount kit (accessory item) is available if it is necessary to mount the RU from a cable. A grounding lug is provided on the bottom of the RU enclosure for connecting a grounding wire.

3.3


The RU detects and reports various faults including remote unit fault, optical fault, output power fault, temperature fault, and power amplifier fault. A single bottom-mounted Light Emitting

Diode (LED) indicator turns from off to red if a major fault is detected. The status of the STM and LPA, the alarm state, and other fault information is summarized and reported over the optical interface to the HU. Fault and alarm information may be accessed at the HU through the

EMS software GUI or remotely through the NOC/NEM interface or SNMP interface.

Page 2-10



3.4

Antenna Cable Connection

The antenna cable connection between the RU and the antenna is supported through a single Ntype female connector. The N-type connector provides a connection point for the antenna cable.

The forward and reverse path RF signals are combined on the same antenna cable. It is recommended that a lightning protector (accessory item) be connected to the antenna port prior to connecting the antenna cable. On an optional basis, the dual-band RU may be equipped with two N-type connectors to support antenna connections to two separate antennas.

3.5

RF Signal Level Adjustment

The RU is equipped with digital attenuators for adjusting the signal level of the forward path RF

output signals. The remote forward path attenuators adjust the level of the two output RF

signals at the RU antenna port and will add from 0 to 31 dB of attenuation to the output signal level. The attenuator can be set in 1 dB increments. The attenuator is software controlled and is adjusted through the EMS software GUI, the NOC/NEM interface, or SNMP interface.

3.6

Optical Connection

Fiber optic connections between the single-band RU and the associated HU are supported through one OptiTap hardened optical connector port. All single-band RU’s are equipped with an internally mounted Wavelength Division Multiplexer (WDM). This allows a single optical port to provide the optical fiber connection for the combined forward and reverse path signals.

Fiber optic connections between the dual-band RU and the two associated HU’s (two HU’s are required with a dual-band RU) are supported through two OptiTap hardened optical connector ports. All dual-band RU’s are equipped with two internally-mounted WDM’s. One port provides the optical fiber connection for the combined forward and reverse path signals for HU

#1. The other port provides the optical fiber connection for the combined forward and reverse path signals for HU #2.

An APC/SC (angled) connector and adapter is mounted within each OptiTap optical port. Drop cables terminated with OptiTap connectors are available separately. The stub end of each drop cable must be routed to an external splice enclosure (not provided) for splicing to the Outside

Plant (OSP) fiber optic cable.

3.7

Powering

The RU is powered by 90 to 265 VAC (nominal 120 or 240 VAC), 47 to 63 Hz power. On an optional basis, the RU may be powered by 60 to 89 VAC, 47 to 63 Hz power. The power is supplied through a three-wire AC power cable that is provided with the RU. The power cable connects to a mini 3-pin power connector mounted on the bottom of the RU enclosure. The stub end of the cable must be hard-wired to the AC power source. The cable is UL and National

Electrical Code (NEC) approved for continuous outdoor exposure without conduit.

3.8

Cooling

Passive cooling of the electronic assemblies is provided by conducting excess heat from the electronic components to the aluminum enclosure. The heat is dissipated to the outside air by radiation and convection air flow over the enclosure’s external cooling fins. An alarm is generated if a high temperature condition occurs within the enclosure. If necessary, the RU may be equipped with solar shields (accessory) that reduce the effect of solar loading on the aluminum enclosure.

Page 2-11



3.9

User Interface

The RU user interface consists of the connectors, grounding lug, and LED that are provided on the bottom of the RU enclosure. The user interface points for the single-band RU are indicated in Figure 2-5 and described in Table 2-3 . The user interface points for the interim single-band and the dual-band RU are indicated in Figure 2-6 and described in Table 2-4 .

When the SNMP interface is required for system operation, both the EMS software and SNMP Proxy Agent software must be installed on the same computer. The SNMP Proxy Agent software will not function without the EMS software.

Control Programs: The host and remote control programs are installed by the factory in each

respective host unit or RU. Updated versions of the host and remote control program software will be provided by Customer Service on a “as needed” basis.

Software Installation

Software installation consists of inserting each specified CD-ROM into the computer’s CD-

ROM drive and then running the software install programs. This places the EMS, Java 2

Runtime Environment, and SNMP Proxy Agent (if included) software files in assigned folders on the computer’s hard drive. Software installation instructions are provided in the Digivance

Element Management System User Manual (See Related Publications section).

5.3

Computer Operation

Permanent control and monitoring functions may be provided by a PC-type desk-top computer that is permanently connected to a HU. The EMS program must be running in order for the

NOC interface to function. Both the EMS program and SNMP Proxy Agent program must be running in order for the SNMP interface to function. A PC-type lap-top computer running just the EMS program can be used as a portable network management tool for service and maintenance purposes. The laptop computer may be connected temporarily to the HU to trouble-shoot problems on-site and then removed when the maintenance task is completed. The specifications for the EMS computer are provided in the Digivance Element Management

System User Manual (See Related Publications section).

5.4

Digivance EMS Computer Interface Connections

The service interface connection between the EMS computer and the HU requires that the EMS computer be equipped with a DB-9 connector that is configured to provide an RS-232 DCE interface. A straight-through RS-232 interface cable (accessory item) equipped with a male DB-

9 connector on one end and a PC-compatible connector on the other end is required to link the

EMS computer to the HU.

The NOC interface connection between the EMS computer and the NOC requires that the EMS computer be equipped with a connector that is configured to provide an RS-232 ASCII interface. The link between the EMS computer and the NOC would generally be supported by a

T1 system, DS0 with RS232 conversion, or other medium. Cables and equipment (not provided) to support the RS-232 interface connection between the EMS computer and the NOC interface are required.

The SNMP interface connection between the EMS computer and the SNMP manager requires that the EMS computer be equipped with an Ethernet port. The link between the EMS computer and a network SNMP manager would generally be supported by a Local Area Network (LAN).

Cables and equipment (not provided) to support the connection between the EMS computer and the LAN are required.

Digivance Software User Interfaces

The Digivance EMS provides three software user interfaces: the EMS Graphical User Interface

(GUI), the Network Operation Center–Network Element Manager (NOC/NEM) interface, and the SNMP interface. The EMS GUI, the NOC interface, and the SNMP interface provide the same basic functions. However, the NOC interface and the SNMP interface cannot be used to download new system software to the Digivance system. In addition, the SNMP interface cannot be used to assign a system site number to a HU/RU pair during installation.

The EMS GUI is used for local control and monitoring operations. The EMS GUI consists of a series of displays and screens, such as the one shown in Figure 2-8 , that provide the user with alarm and status information and that allow the user to set various operating parameters.

Directives are implemented by pointing and clicking on the desired action and also by entering text in various dialog boxes. Refer to the Digivance Element Management System User Manual

(see Related Publications section) for additional information.

Figure 2-8. Typical EMS Graphical User Interface – Host/Remote Alarms Display

The NOC/NEM interface is a text-based command line interface that is used for remote control and monitoring operations (except software download). The NOC/NEM interface consists of defined ASCII text strings that are input as SET or GET commands followed by the action or information required. A text string response is received from the specified Digivance 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 2-9 . 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 locally from the EMS computer. Refer to the Digivance Element Management System User Manual

(see Related Publications section) for additional information.
