OOK

This book presents information that explains the concepts behind the design and operation of the Open Reliable Communications Architecture (ORCA) telephony gateway. Specifically, this book provides information on the RDT-8v release 7.1 gateway, the GX release 8.0 gateway, the RDT-

8v release 7.0 gateway, the RDT-8g release 7.0 gateway, and the BTX-8 release 1.0 gateway. It provides system design and application information, and product features. The purpose of this information is to help you install, use, and maintain an ORCA gateway.

Who Should Use This Book

This book is for product distributors, systems integrators, systems analysts, and network administrators who design, install, configure, and maintain wide area networks (WANs) and large-scale communications applications. It contains conceptual and practical information about how to use the

ORCA gateway within your network.

How To Use This Book

If the ORCA gateway is new to you, you should read all the chapters in this book to familiarize yourself with all of the

product features and functions. In addition, see "ORCA User

Library" on page vi for an annotated list of books in the

ORCA library.

If your network is already functional, you can use the ORCA

Hardware Manual to install a gateway, and then use the included software manual, (e.g., ORCA GX-Series Software

ORCA Gateway Hardware Manual

Manual) to learn how to use the Nuera network management software to configure the gateway. If you need more information to help you integrate an ORCA gateway into your network, refer to the manuals that support your network components.

Conventions Used in This Book

This book uses specific conventions to show the following types of information:

• Number usage

• Replaceable input values

• Messages

Read the following sections to learn more about how this information is shown in the rest of the book.

How Numbers Are Used

When numbers are shown in this book, they can appear as descriptive values or as data to be manipulated internally.

Decimal values are used frequently; however, alternate number bases are useful when internal data is shown.

Large Decimal Numbers

Numbers greater than 9999 display in SI metric style, where whole numbers that contain more than four digits are broken into groups of three digits that are separated by spaces. For example, the number sixteen thousand three hundred eighty three is shown as 16 383. This avoids confusion between American and European punctuation conventions.

xviii

About This Book

However, a number that is internally manipulated by a computer is shown without punctuation or spaces. For example, notice how the value 65 535 appears in the following instruction without a space or a thousands separator within the number:

Specify 65535 as a maximum value

Numbers with Different Bases

All numbers shown in this book are decimal values unless the number base is binary or hexadecimal. There are two ways to show a number with a different base:

• An identifier can precede a binary or hexadecimal number. The following expressions use an identifier:

• the value of binary 1010

• the value of hex 4F

• A type-format indicator can precede a binary or hexadecimal number that is enclosed in single quotation marks.

The following expressions use the binary and hexadecimal indicators:

• B’1010’

• X’4F’

Replaceable Input Values

In some cases, you can insert user-defined values into commands or you can specify local paths and filenames. These variable values are shown in italic typeface.

For example, you might be asked to specify the name of your server in this path:

A:\LOGIN\LOGIN servername

The italic typeface shows that you need to replace server-

name with your local server name. xix

ORCA Gateway Hardware Manual

When you are prompted for variable input that is represented by lower-case letters, follow these conventions:

Substitute This Value n x b h

When You See This

Variable Value

Any binary digit

Any hexadecimal digit

Any decimal digit

Any alphabetic value, such as:

Multiple letters

x:\DOS

where you substitute the correct drive letter for x

A series of digits, such as:

FIRST 2 HEX BYTES: hhhh

where you substitute four hexadecimal digits for hhhh

When you are prompted for variable input with embedded decimal points, replace the variable digits and let the decimal points remain to separate 32-bit dotted-decimal address segments. For example, you might be prompted to supply a

32-bit, dotted-decimal address in this format:

nnn.nnn.nnn.nnn

where nnn is a decimal value from 0 through 255. Leading zeros are not required.

Textual Callouts

This book uses two distinct symbols displayed in the textual margins to call the reader’s attention to information that is of particular interest.

This overview is a high-level introduction to the ORCA gateway hardware components. ORCA gateways provide highdensity voice transmission that enables high-quality, costefficient telecommunications service. This chapter explains the gateway design and the ORCA network design.

ORCA GX-Series Release 8.0

Overview

Currently, only the 21-slot chassis supports ORCA GX release 8.0.

An ORCA 21-slot gateway has the capacity to support up to

2016 channels of packetized voice over IP packets. It is able to interact with an external softswitch, such as Nuera’s SSC

Softswitch, for a switched network solution.

Design

This section presents high-level information about the design philosophy of the ORCA gateway platform. The

ORCA gateway has been designed to serve carrier-grade environments that require:

• Open architecture

• High reliability

• High scalability

• Hot-swap capability

• Interoperability

• NEBS compliance

Open Architecture

The open architecture of the ORCA gateway facilitates interoperability with third-party softswitches, gateways, integrated access devices, and enhanced services platforms.

High-Reliability

The ORCA gateway’s robust platform provides sufficient redundancy to guarantee high availability. Because ORCA gateways carry large amounts of revenue-producing voice traffic, hardware or software faults are contained and not permitted to affect other system resources.

The ORCA gateway design enables distributed execution of control and processes, while its hot-swap capability enables all cards to be easily replaced in case of failure. These modules do not require special tools to perform field replacement.

Control processes and signaling are backed up by a dual- processor configuration that has access to all the internal buses.

Scalability

The ORCA 21-slot chassis release 8.0 supports between 1 and 3 DS3s of voice traffic. This enables emerging carriers to enter the market with a relatively low cost entry level product, which can easily be expanded as their business continues to grow.

24

Overview

Hot-Swap Capability

The gateway’s voice processing is performed by replaceable components that can be hot-swapped in the event of a failure. Control and switching modules are backed up by a dualprocessor configuration that accesses all internal buses. In addition, power and fan modules are also redundant and hot-swappable.

Interoperability

The ORCA gateway products are based upon an open architecture and protocols common to both legacy and evolving voice/data networks. These include voice compression algorithms such as G.729, signaling systems, packet formats

(IP), and networking protocols (MGCP and SIP). Because the architecture is software intensive, it is easy to select specific features for a given application in order to maximize performance and minimize cost.

ORCA gateways also interoperate with third-party gateways and softswitches, as well as with Nuera’s own SSC softswitch. Nuera’s gateways support the industry standard

MGCP; Nuera’s SSC supports MGCP and SIP.

NEBS Compliance

The ORCA gateway products are certified to be Network

Equipment Building System (NEBS) Level-3 compliant. The rack depth of an ORCA gateway series chassis, for example, is suitable for mounting in a NEBS 24-inch-frame floor plan.

For complete information regarding NEBS, see “Network

Equipment Building System Generic Equipment Requirements”, TR-NWT-000063, Issue 4, July, 1991.

Networking

The ORCA gateway product family is a networking system that provides highly efficient and reliable transmission of voice, voice band data (VBD), modem, and facsimile (fax) signals across a broad range of digital transmission facili-

ties. It uses advanced signal processing techniques to characterize and compress signal sources into data packets that are compatible with IP or leased-line wide-area networks

(WANs).

The ORCA gateway can be employed as a trunking gateway between both local and/or toll switches, or as an access gateway.

ORCA Gateway

The cornerstones of an ORCA network are the ORCA Gateway components–the ORCA voice/media gateways. ORCA gateways create a telephone switching platform that provides network access for as many as 84 digital T1 subscriber interfaces on the 21-slot chassis. The associated voice channels originating from these interfaces are compressed, packetized, and routed across IP network backbones.

Ethernet connectivity and support functions, such as network management systems (NMS) connect to an ORCA gateway through one of the redundant 100Base-T or

1000BaseSX connections on the unit’s HUB2X card. See Figure 1 on page 27.

ORCA SSC Softswitch

The ORCA SSC softswitch provides the call processing and call control for one or more GX-Series gateways. The SSC is built on Hewlett-Packard server platforms.

The ORCA SSC centralizes and simplifies dynamic switching, routing, management, and call processing feature operations. While providing the network call processing and routing abilities, the SSC also provides a portal to enhanced services such as Interactive Voice Response (IVR), and voice/ fax messaging.

The SSC and GX-Series gateways communicate using the

Media Gateway Control Protocol (MGCP), enabling creation of geographically distributed softswitches. Using the MGCP protocol, the SSC controls the GX-Series units within its domain and thereby provides the functionality of a traditional telecommunications switch. The relationship between the GX-Series voice gateway and the ORCA SSC is that of client and server, respectively.

27

ORCA Gateway Hardware Manual

Primary Functions

The main tasks performed by the ORCA SSC are:

• Communicating with other network domains using signaling protocols such as SIP signaling protocol

• Providing signaling services such as MGCP and SS7 to the ORCA GX-Series gateway

• Routing calls to and from the ORCA SSC-managed network from other networks

• Managing call-related resources such as ports, trunks, and routes

• Recording call accounting data

Figure 2 shows the relationship of the ORCA SSC softswitch

to the ORCA Gateway.

ORCA SSC Configuration

The ORCA SSC can be deployed individually or in redundant pairs to provide maximum network reliability.

A single SSC can support a network of up to twenty-five

ORCA voice gateways. SSCs can also be deployed regionally and operate together to provide the call processing and switching structure for large scale networks.

Overview

ORCA RDT-8g Overview

Currently, only the 8-slot chassis supports ORCA RDT release 7.0.

Nuera's ORCA (Open Reliable Communications Architecture) RDT (Remote Digital Terminal) product is designed to bridge the gap between traditional, circuit-based Public

Switched Telephone Networks (PSTNs) and the emerging packet-switched networks (i.e., cable telephony). The ORCA

RDT provides an excellent solution for merging digital broadband access networks with the legacy telephone network in a seamless, reliable manner. To accomplish this, the

ORCA RDT supports Network Call Signaling (NCS), Packet-

Cable’s version of Media Gateway Control Protocol (MGCP) that defines a signaling connection between Voice-over-IP

(VoIP) network devices. The RDT series also supports the

GR-303 standard, which defines an interface between a digital switch that provides local service and an access concentrator.

ORCA Design

This section presents high-level information about the design philosophy of the ORCA RDT platform. The ORCA

RDT has been designed to serve carrier-grade environments that require:

• Open architecture

• High availability with redundancy

• High scalability

• Hot-swap capability

• NEBS compliance

Open Architecture

The internal open architecture of the ORCA RDT facilitates third-party software development or integration of off-the-

29

ORCA Gateway Hardware Manual

shelf applications. By implementing a software version change, the ORCA RDT becomes capable of interfacing with an external, third-party soft switch.

High-Reliability

The ORCA RDT’s robust platform provides sufficient fault tolerance and redundancy to guarantee high availability.

Because ORCA RDTs carry large amounts of revenue-producing voice traffic, hardware or software faults are contained and not permitted to affect other system resources.

The ORCA RDT design enables distributed execution of control and processes, while its hot-swap capability enables all cards to be easily replaced in case of failure. These modules require no special tools or training to perform field replacement.

Control processes and signaling are backed up by a dual- processor configuration that has access to all the internal buses.

Scalability

The ORCA RDT supports between 1 and 16 T1s per chassis, using uncompressed, G.711 or G.726-32k packetized Voiceover-IP (VoIP) with GR-303 and NCS protocols. This enables emerging carriers to enter the market with a relatively low cost entry level product, which can easily be expanded as their business continues to grow.

Hot-Swap Capability

The RDT’s voice processing is performed by resource cards that can be hot-swapped out in the event of failure. Control and switching modules are backed up by a dual-processor configuration that accesses all internal buses. In addition, power and fan modules are also hot-swappable.

30

Overview

NEBS Compliance

The ORCA RDT product is certified Network Equipment

Building System (NEBS) Level-3 compliant. The rack depth of an ORCA RDT series chassis, for example, is suitable for mounting in a NEBS 24-inch-frame floor plan. For complete information regarding NEBS, see “Network Equipment

Building System Generic Equipment Requirements”, TR-

NWT-000063, Issue 4, July, 1991.

Feature Summary

This section provides an overview of the ORCA RDT’s features.

Voice Processing

• Built in adaptive echo cancellation with automatic convergence from 0–54 milliseconds

• Adaptive jitter buffer from 10–750 msec

• Advanced lost packet recovery (LPR)

Protocol Support

The ORCA RDT supports the following industry protocols:

GR-303

GR-303 defines an interface between a local digital switch (Central Office) and a remote digital terminal

(RDT). GR-303 is a legacy PSTN protocol that has been in use since the early 90s. The PSTN forms temporary circuits, apportioning a dedicated, private channel between two speakers. GR-303 is used to define an access telephony network in front of a local exchange switched network. GR-303 protocol supports call processing and OAM&P functions required by the switches that are in the local exchange switched network.

31

ORCA Gateway Hardware Manual

Network Call Signaling (NCS)

NCS is PacketCable’s version of Media Gateway Control

Protocol (MGCP). Using NCS, the ORCA RDT can communicate directly with cable modems to establish a voice call. PacketCable is the industry consortium for definition and standardization of cable telephony networking.

Fax and Modem Support

The ORCA RDT supports Group III fax protocols V.17, V.21,

V.27 and V.29 at baud rates up to 14.4 Kbps as well as high speed modem standards such as V.34. The fax and modem signals will be passed through the ORCA RDT with no degradation of performance.

Maintainability

The following list describes the salient maintainability features of the ORCA RDT:

• Hot-standby redundant capability on all control and switching modules. Live insertion and extraction of all modules

• Built-in test capability to identify and isolate failed modules

• Maintenance and configuration functions are performed remotely through the ORCA network management system

ORCA RDT-8v Overview

Currently, only the 8-slot chassis supports ORCA RDT releases 7.0 and 7.1.

Nuera's ORCA (Open Reliable Communications Architecture) RDT-8v (Remote Digital Terminal) product is designed to bridge the gap between traditional, circuit-based Public

Switched Telephone Networks (PSTNs) and the emerging packet-switched cable telephony networks. The ORCA RDT-

32

Overview

8v provides an excellent solution for merging digital broadband access networks with the legacy telephone network in a seamless, reliable manner.

The ORCA RDT-8v is programmed to use and convert three different protocols that together make routing voice packets over different networks possible. The first set of protocols are G.711 PCM and G.726-32k ADPCM, which make the voice packets ready for transmission through IP networks.

Both are standards for converting speech into discrete packets. The ORCA RDT also supports Network Call Signaling

(NCS), PacketCable's version of Media Gateway Control

Protocol (MGCP) that defines a signaling connection between Voice-over-IP (VoIP) network devices. Finally, the

RDT-8v supports the V5.2 standard, which defines an interface between a digital switch that provides local service and an access concentrator.

The ORCA RDT-8v converts information in real time between all three protocols, forming IP packets from the

PSTN PCM speech and sending them to a cable modem; or stripping off the encapsulation from the IP packets, reassembling the speech packets, and sending the PCM equivalent to the switch.

OMPONENTS

This chapter presents the functional architecture of the

ORCA 21- and 8-slot gateways. It introduces the major gateway components, their functions, and inter-activities.

All chassis logic modules, power supplies, and the fan modules reside in a 21-slot, compact PCI (cPCI) chassis. Each slot permits the installation of a front and a rear card module separated by a midplane, which is functionally equivalent to a backplane. For more information on the ORCA

gateway logic modules, see "ORCA Gateway Card Modules" on page 51. The 8-slot gateway uses the same logic modules

and midplane design as a 21-slot chassis.

Chassis Overview

Dimensions

The 21-slot chassis encloses a card cage, two power supply modules at the bottom of the chassis, and two fan modules at the top. The chassis, which is made in compliance with the cPCI specification, fits into an Electronics Industry

Association (EIA) standard 19-inch rack and houses 21 single-width cards. The chassis is 28 inches tall.

41

ORCA Gateway Hardware Manual

The 8-slot chassis encloses a card cage, four power supply modules at the top of the chassis, and two fan trays on either side of the chassis. The chassis is also made in compliance with the cPCI specification and the EIA 19-inch standard racks. The BTX-8 chassis is 10.5 inches tall and houses

8 single-width cards.

Intercard Signals

Many intercard signals can be grouped as busses described as follows:

H.110 Bus

This is the ECTF standard PCM highway. It provides 32

8.192 MHz highways for a total capacity of 4096 64Kbps channels.

100Base-T LANs A/B

These are two independent, 100Base-T ethernet LAN segments per slot supported by redundant, switched

HUB2 modules.

Auxiliary Bus

This bus provides miscellaneous interconnects. Signal functions include: power-supply monitor and control, system resets, power, fan monitor and control, temperature monitor, alarms, and hot-swap status and control.

PCI Standards

The ORCA hardware system implements the industry standard compact PCI (cPCI) specification. cPCI enables the porting of IBM PC architecture to an industrial-grade platform. The PCI bus used by most Pentium-based PCs is the core of the cPCI electrical specification.

The backplane PCI bus has a high-speed, impedance-controlled design.

42

Chassis and Components

Power Supplies

The two power supplies are accessible from two drawers at the bottom front of the ORCA 21-slot chassis. On the 8-slot chassis, the four power supplies are accessible from the front top of the chassis. All modules operate in parallel with each other and are hot-swappable. If any power supply fails, sufficient power continues to be available from any remaining supplies.

Power modules are equipped with single line inputs to support two separate power grids. Input line power is not bussed.

For information on how to hot-swap the power modules, see

"21-Slot Chassis Power Modules" on page 112 for the 21-slot

chassis, or see "8-Slot Chassis Power Modules" on page 117

for the 8-slot chassis.

Fan Modules

In the ORCA 21-slot chassis, cooling is provided by two fans installed in side-by-side hot-swappable trays located at the top of the enclosure. The fans draw air into the bottom of the unit. It then traverses upward past the card modules and exits from the top rear of the unit.

In the ORCA BTX-8, cooling is provided by two hot-swappable fan trays installed on each side of the unit. The fan trays draw air from the air inlet located on the right side of the unit to the exhaust vent located on the left rear side of the unit.

The ORCA gateway system detects fan operational status through a tachometer reading. If fan output is compromised by failure or loss of rotational speed, an alarm condition is reported by the CM module. The failed module can then be replaced while the ORCA gateway is powered on, thereby restoring full cooling capacity to the gateway.

43

ORCA Gateway Hardware Manual

For information on hot-swapping the fan modules, see "21-

Slot Chassis Ventilation" on page 117 for the 21-slot chassis,

ORCA Gateway Hardware Manual

CM Module

The control module (CM) controls and coordinates all resources within an ORCA chassis. All configuration and control processes pass through the active CM before being distributed to other boards.

To avoid the failure of system control, two identical control clusters are used to control two LANs. Each control cluster consists of two pairs of modules (CM/CMX and HUB/HUBX) which independently control a LAN. The control clusters are labeled either A or B in association with the two LANs, also labeled A and B. The labels do not imply primary/secondary or online/offline operation.

In the event the active cluster fails, the system switches automatically to the offline (standby) cluster. This hand-off of control provides continuous system operation in the event of a control cluster failure. The failed (newly offline) cluster can then be replaced.

CM3 Module

The CM3 module is an updated version of the CM module, designed with the processing power to handle the higher traffic load of multiple DS3 connections found in the GX-

Series release 8.0 product. The CM3 is available only for that product.

HST Module

The High Speed Telecom (HST) module, together with the

HSTX module, provide the high-speed interface for the

ORCA gateway. Its function is to perform multiplexing on the incoming DS3 channels. The HST splits out the 2016 bidirectional PCM channels and delivers the payload to the various UPM3 modules for processing and packetization

52

ORCA Gateway Card Modules

using the H.110 interface. The HST also performs inverse multiplexing and framing for outgoing signals.

HUB2 Module

The HUB2 module is an ethernet switch with segments to all other modules. The internal LANs enable the CM, UPMs,

HSTs, and the external LAN to transfer control, status, and payload data with each other. A gateway chassis has two

HUB2s, each servicing one of the two internal LANs.

The HUB2 is a switched hub; it divides its transmit and receive time between any number of concurrent connections, allowing data to pass through the HUB2 rapidly and efficiently. The HUB2 also supports simultaneous two-way traffic with full and half duplex modes and supports the HUB2X which has a gigabit or a 100 Mbps ethernet interface.

UPM3 Module

The Universal Processor Module (UPM3) is the payload processing module of the gateway. It is responsible for processing and packetization of the traffic on the voice channels within the ORCA gateway.

The UPM3 is processor intensive, having multiple digital signal processors (DSPs) controlled by a high-capacity microprocessor. It supports:

• Ethernet LAN segments (2)

• DSPs (8)

• H.110 interface

UPM4 Module

The UPM4 module is an updated version of the UPM3 module, designed with a faster processor to handle the higher

ORCA Gateway Card Modules

Module Redundancy

The ORCA gateway is designed to allow for a distributed execution of control and processes to minimize service loss due to module failure. In the event of module failure, components can be hot-swapped, thereby permitting the gateway to continue in operation.

Voice processing is performed by resource cards that can logically be swapped out in the event of a failure. Control processes are backed up by a dual-processor configuration that has access to all of the internal buses.

Control Clusters

Central to the ORCA gateway design are functional groups of plug-in modules called control clusters. A control cluster consists of related CM, CMX, HUB2, and HUB2X modules.

ORCA gateway design provides two control clusters; one cluster is a redundant backup for the other.

In normal operation, the active CM monitors operational status of its cluster (HUB2, HUB2X, CMX) by monitoring individual cluster members. It also polls all UPM3 and HST modules through the ORCA internal bus system.

The standby CM monitors activity in the active cluster and its own cluster, mirroring activity in the active cluster without assuming control of the bus system. The standby CM also monitors activity of all UPM3 and HST modules.

In the event of a failure, or a loss of performance in the active control cluster, the ORCA gateway can automatically notify the NMS and switch control to its standby control cluster, thereby maintaining the system in service.

The ORCA gateway then continues operation under control of the redundant control cluster indefinitely, until a failure or loss of performance again initiates switchover. (This can

63

ORCA Gateway Hardware Manual

Note

also be activated by issuing the appropriate command from the Nuera Configurator.)

After a switchover, the now inactive control cluster can be diagnosed and repaired and returned to a “warm” standby state.

The standby control cluster does not respond to console commands.

HST Clusters

A HST cluster consists of related HST and HSTX modules.

ORCA gateway design provides two HST clusters; one cluster is a redundant backup of the other. In normal operation, the active CM monitors the operational status of both HST clusters as well as the DS3 alarm status. In the event of a failure, either on the card or on a DS3 port, the active CM can switch the active HST cluster.

If the CM sees the same DS3 port alarms on both HST clusters, it will not switch the active HST cluster. This redundancy feature allows active calls to proceed with minimal disruption when a fault to one of the HST clusters occurs.

HASSIS

An ORCA gateway ships with all of its cards installed, making on-site hardware installation a simple process. The hardware installation section contains a list of necessary equipment and step by step instructions.

Nuera provides a sophisticated graphical user interface

(GUI) for system configuration, monitoring, and troubleshooting. These functions are performed by one of two solutions: the Nuera Configurator or NueraView. See the software manual (e.g., GX or RDT) for more information.

Installation Preparation

There are numerous preparations that should be performed prior to installing a gateway. The following information should allow you to prepare the installation site to met the gateway’s requirements and guidelines.

ORCA Gateway Hardware Manual

Site Environment Guidelines

Power Requirements

The site must provide either:

• 100- 250V

~

(VAC), 50/60Hz, 15A max.,

• or -42 to -62.5 V

– – –

(VDC), 30A max.

main power to each power supply module installed in the gateway. Each power feed must deliver 1.2 Kilowatts minimum power per gateway. Nuera recommends redundant power supply feeds to ensure the continuous operation of the gateway.

AC units should be wired using 14 AWG wire. DC units should be connected using 10 AWG wire. For more details on

the power requirements, see "Specifications" on page 143.

Space Allocation Guidelines

The gateway can be installed in an open rack, or in an enclosed cabinet as required by the site. The following installation options are currently supported:

• Open rack (provided by the site): EIA standard 19” rack used in an interior installation only. The 21-slot chassis can be front-mounted or center mounted in the rack. A single gateway requires 26.25” of vertical rack space, and 20” of rack depth.

• Enclosed environmental cabinet supplied by the site.

• A 23” Open rack can be used with adaptor mounts.

Airflow Requirements

Each 21-slot gateway is equipped with dual fan modules capable of providing 500 CFM of forced-air ventilation. The air intake is located on the lower front and side sections of the chassis, just above the power supplies. To prevent overheating, the air intake must not be obstructed. The exhaust

66

Installing the ORCA 21-Slot Chassis

vent is located on the upper 3.5” section on the rear of the gateway. The ambient temperature of the installation site must not exceed 50 C.

The gateway produces heat at a maximum of 4500 BTUs per hour. The facility air conditioning system must be capable of handling system cabinet heat to reduce the system cabinet air temperature to an acceptable level for proper operation.

The air conditioning system specifications should provide this information. Also, Nuera recommends that the limit for ambient dust content per cubic foot of air is 7,000 particles of one-micron size or larger. The air conditioning system specifications should provide this information as well.

Safety Precautions

Caution

• The ORCA 21-slot chassis with power modules removed weighs approximately 110 lbs. Ensure that adequate manpower is available before attempting to remove the chassis from its shipping crate.

• For DC-powered gateways, connection to the -48 VDC power supply must be made with AWG 10 wires optionally supplied with the ORCA gateway. These AWG 10 wires must be secured by the cable clamps on the gateway and to the shelf (or rack) every 6 inches (15.24 CM3) thereafter.

• For AC-powered gateways, connection to the AC line must be made with AWG 14 wires optionally supplied with the

ORCA gateway. These AWG 14 wires must be secured by the cable clamps on the gateway and to the shelf (or rack) every 6 inches (15.24 CM3) thereafter.

• When installing or modifying telephone lines:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

• Before connecting an ORCA gateway to a data communications or telecommunications network, ensure that a qualified professional verify that the gateway is connected to a safety/earth ground both through the

AC mains connector and directly through the terminal at the rear of the chassis.

68

Installing the Chassis

Installing the ORCA 21-Slot Chassis

The ORCA 21-slot shipping crate is sealed with approximately 17 lag bolts. Use a 7/16” SAE socket wrench with a ratchet handle or other appropriate tool to remove the bolts.

Ensure that the shipping crate is in its upright position prior to removing the lag bolts.

The front panel can then be removed, providing access to the

ORCA 21-slot chassis and ancillary equipment.

When choosing the location to physically install the ORCA gateway and the mounting racks, it must be in a restricted access location, where access can be gained only by service personnel or by users who have been instructed in the precautions that must be taken. Also, proper security measures should be taken into consideration.

The ORCA 21-slot chassis is shipped with system front and rear card modules and fan modules installed. It is positioned within the shipping crate in its upright position. A blank panel is mounted over the two power supply bays to maintain the card cage in a rigid state during shipment. See Figure 13:

Caution

Power should only be applied to the ORCA gateway after a thorough inspection of all connections made. Allow no frayed ends or exposed uninsulated wire. Ensure that the ORCA gateway power switches are in the Off (0) position.

Energize the DC or AC power mains by moving the respective circuit breaker actuators to their On (1) position.

Apply power to the ORCA 21-slot gateway by moving power switches for both power modules to their On (1) position.

Observe that the ORCA gateway’s fan modules and power modules indicate green LEDs. The ORCA gateway’s poweron self-test (POST) initiates. See Figure 24 on page 82.

Installing the ORCA 21-Slot Chassis

If a slot configuration exists for each installed module, the module is programmed automatically. Use the ORCA NMS

(either NueraView for ORCA or the Configurator) to configure the slot and place the module online. See the online help for information.

Signal Cables

ORCA cables are optionally provided with the ORCA gateway. Connector types vary depending on the ORCA gateway configuration and existing ancillary equipment types.

ORCA 21-slot gateway connector types include DB-9M, DB-

15F, DB-25M, BNC, and RJ-45F connectors.

Ancillary equipment connector types can vary with the application. Use cables with appropriate connector types to suit required interface types. For specific information about

available ORCA gateway cables, see "Cables and Connectors" on page 161.

All gateway signal cables connect at the rear of the ORCA chassis. Use cable run and bend radius information gathered during the site survey to run appropriate lengths of signal cables between the ORCA gateway and ancillary equipment. Be sure to fasten cable anchor screws and clamps.

Connecting the HSTX Bridge Card

Cables

The HSTX Bridge card consists of twelve BNC connectors to terminate up to three DS3 circuits. The center column of the

BNC connector array terminates coaxial cables connecting the gateway to the carrier demarcation point. Each DS3 circuit requires two coaxial cables: one to transmit, and one to receive.

83

ORCA Gateway Hardware Manual

Passive electronic components of the HSTX/Bridge split the

DS3 circuits to the outer two columns of BNC connectors.

The outer two columns of BNC connectors are then connected to the HSTX cards via coaxial cables as shown below

in Figure 25.

88

Figure 27. ORCA 8-Slot Chassis

Caution

The ORCA 8-slot chassis with power modules installed weighs approximately 45.3 lbs (20.55 kg). Ensure that adequate manpower is available before attempting to remove the chassis from its shipping container.

The gateway is intended only for installation in a restricted access location. The recommended maximum operating temperature is 50 C. When installing the chassis in a multi-unit rack assembly or in proximity to other operating equipment, measures should be taken to ensure that the maximum operating temperature of the gateway is not exceeded. Likewise, measure should be taken to ensure that airflow is not compromised.

3. Remove the 8-slot chassis from its shipping container.

4. The 8-slot chassis is shipped with its rack-mount ears positioned for front (flush) mounting. To center mount the chassis, use a #2 Phillips screwdriver to remove the five #6-32 screws affixing each rack-mount ear. Reposition the rack-mount ears to the center mount position.

Replace all screws. Take care that the rack is correctly mounted, so that a hazardous condition is not created due to an uneven mechanical load.

5. Ensure that eight rack-mount screws appropriate in size for your rack are immediately available. (Typically #10-

32, or #10-24. Check your rack for proper screw size.)

Note

Installing the ORCA 8-Slot Chassis

6. Lift the chassis and position it in the rack. Ensure that all holes in the mounting ears align with holes in the rack. Install one screw in the bottom corner of each side using an appropriate tool. Allow the installed screws to support the weight of the chassis while installing the remaining six screws.

All eight screws must be installed.

For racks with equipment shelves installed, lift the 8-slot chassis and position it on the shelf. Install the eight mounting screws.

Remember to check the nameplate rating to ensure that there is no overloading of the supply circuits. Also, reliable earthing of rack-mounted equipment should be maintained.

Supply connections other than direct connections to the branch circuit should be given careful attention.

Connecting Main Power

8-slot gateways are configured for either DC or AC power. If the gateway is redundant, both power supply pairs are designed to accept separate power feeds. ORCA sites must provide either two independently fault current protected -48

VDC power feeds or two independently fault current protected 110–240 VAC power feeds. DC power feeds should be fault current protected at 15 Amps. AC feeds should be fault current protected at 7 Amps minimum.

Grounding the ORCA Unit

Caution

Installation must be performed by a qualified service person who is skilled in the installation and connection of power distribution systems to ORCA-class equipment and is knowl-

89

ONFIGURATION

This chapter describes the configuration functions performed through the ORCA gateway’s console port. It also provides specific instructions for configuring a gateway using console port commands.

The Console Port

The console part plays a small yet crucial part of bringing an

ORCA gateway online in a network. The port is located on the CMX card. It is a DB9 (M) serial port, and is intended to connect a computer directly into the gateway to assign basic configuration information.

Once a computer has been connected to the port, a terminal emulation program, such as Procomm Plus

TM

, should be used to access the gateway. Use the settings below to correctly configure the emulation program:

• 9600 bps (ANSI ASCII format)

• Parity: None

• Bits: 8

• Stop bits: 1

The following network settings must be configured or the gateway will not function:

99

ORCA Gateway Hardware Manual

• ethernet subnet mask

• default network gateway

• ethernet IP address.

Configuring these settings, specifically the IP address, will trigger the storage initialization process, which requires the gateway to be power-cycled. When the gateway comes back on-line, the new settings will be intact.

See “Ethernet Commands” on page 104 for more information

on how to configure these settings.

Console Port Commands

This section presents the complete list of ORCA gateway commands that you can enter through the unit’s console port. These console port commands serve to configure the gateway initially. Once the ORCA gateway is functional, the remainder of the configuration is performed through either the ORCA Configurator or a SNMP network management system (like NueraView).

100

Configuration

SNMP Community String Commands

SNMP community strings allows you to set low-level security for an ORCA gateway. With community strings, you can assign names to all your ORCA gateways. That name will be embedded in every header packet the gateway sends out. When an ORCA gateway and the Nuera PC workstation have community strings enabled, they will both embed the same name in their messages, and will verify the name in the header, throwing away any packets from nodes that do not contain the configured community string. The community string setting defaults to public. If this default setting is changed using the console port commands, the corresponding community string pop-up in NueraView needs to be altered to match.

There are two community string commands:

manager community show, and

manager community that are described below.

MANAGER COMMUNITY SHOW

Displays the current community string name listed for the

ORCA gateway.

MANAGER COMMUNITY <STRING>

Parameters

<STRING>

specify the designation you wish the ORCA gateway to be identified by.

101

ORCA Gateway Hardware Manual

MANAGER COMMUNITY <INDEX> <STRING> <R/RW>

This command is applicable to the RDT-Series gateways.

RDT gateways support up to four community strings using the following parameters:

Parameters

<INDEX>

Specifies one of five community strings where <INDEX> is 1,2,3, 4 or 5.

<STRING>

Specifies the designation you wish the ORCA RDT gateway to be identified by. Specify a string of up to 32 alphanumeric characters.

<R/RW>

This parameter is used to grant read-only, or read-write privileges to the gateway accessed by the specified community string.

102

Configuration

Packet Sniffing Debug Commands

The debug command sets up the ORCA gateway to send debug strings to a remote host. The remote host needs to be running a packet-sniffing program to read and log the messages. This command is intended to be used for debugging and troubleshooting purposes.

DEBUG OUTPUT <SYSTEM|CARD> <IPADDR> MASK FFFFFFFF

The debug output command configures the gateway to start sending the debug messages. The debug output command must be used with the mask option. Mask refers to bitmap masking. It is recommended to use the FFFFFFFF masking definition. This option will send all generated debug messages to the remote packet sniffer.

Parameter

<SYSTEM|CARD>

Choose between the system and card operands. Select

system

if you wish to see the debug messages sent from the CM card and all the UPM3 cards in the box. Select

card

if you wish to see the debug messages sent from the CM card only. To see messages from the secondary

CM card, you must plug into the console port on the secondary card and use the debug output command to configure that card separately.

<IPADDR>

Specify the decimal IP address of the remote system that runs the packet sniffer. For example, 120.43.254.2.

This address is assigned locally by your network administrator. Use UDP port 1301 for all debugging traffic.

DEBUG SHOW

The debug show command lists the current debug settings on the gateway.

103

Ethernet Commands

The ethernet command group provides LAN configuration parameters for the ORCA gateway. There are four ethernet commands:

ethernet default,

ethernet ip,

ethernet mask, and

ethernet show.

ETHERNET DEFAULT <1|2|3|4> <IPADDR>

Sets the IP address of the ORCA gateway or router that the

ORCA chassis uses as a default gateway. When the unit sends IP messages to a destination that is not on its subnet, these messages are directed to the gateway device for forwarding to the appropriate network.

Parameters

<1|2|3|4>

Specify the default gateway device. Multiple default gateways are not currently supported; therefore, you must specify 1.

<IPADDR>

Specifies the decimal IP address of the gateway device.

For example, 120.43.254.2. This address is assigned locally by your network administrator.

ETHERNET IP <IPADDR>

Sets the IP address of the active control module (CM) in an

ORCA gateway.

104

Note

Configuration

Parameter

<IPADDR>

Specifies the decimal IP address of the ORCA gateway.

For example, 120.43.254.2. This address is assigned locally by your network administrator.

ETHERNET MASK <IPMASK>

Sets the identifier for a network subnet, which shares a network address with other portions of the network and is distinguished by a subnet number. The subnet may be a physically independent network.

Parameter

<IPMASK>

Specifies the ORCA gateway’s internet subnet mask number. This address is assigned locally by your network administrator. For example, 255.255.255.0.

ETHERNET SHOW

Displays the current ethernet settings for the ORCA gateway.

The active CM's IP address, the subnet mask, and the default gateway can all be viewed from the NMS, but can only be changed from the console. During installation, set these parameters from the console before contacting the unit with

NueraView.

NANCE

This chapter presents maintenance procedures for the

ORCA gateway and its components. All card assemblies, power modules, and fan modules, and software can be replaced on site, as explained in this chapter. In addition, the fan filters and power supplies require periodic cleaning.

For service to other parts and chassis components, contact

Nuera or your authorized service provider to have an ORCA gateway serviced properly.

Power Precautions

Caution

Electric Shock Hazard: Before servicing an ORCA gateway, remove all connections to AC/DC power line and public telephone network lines. Contact the Nuera TAC or your authorized service provider if you have any questions regarding this procedure.

When performing maintenance or repair procedures on an

ORCA gateway that require accessing the internal assembly or cable ports, observe the following precautions to avoid possible injury:

ORCA Gateway Hardware Manual

• Always unplug the AC power cord and any connections to the public telephone network before removing the cover from an ORCA gateway.

• Be aware that certain power supply surfaces (including heat sinks) could be at a high voltage potential.

Caution

Electrostatic Discharge: When performing maintenance or repair procedures on an ORCA gateway, note that all of the internal assemblies and cable ports on the rear panel are susceptible to damage from Electrostatic Discharge (ESD).

To reduce the possibility of damage to these devices, always observe standard ESD handling precautions, including (but not limited to) the following:

• Avoid touching circuitry or conductive components of the gateway or its subassemblies.

• Place the gateway and all subassemblies on a grounded anti-static mat whenever maintenance is performed.

• Use an approved personal grounding device (such as a wrist strap) at all times when handling these products.

• Use only approved anti-static containers when shipping or moving any of these products.

Failure to observe these precautions could result in serious damage to these products with either immediate or latent operational failure or performance degradation. ESDrelated failures due to improper handling may affect the coverage under your warranty.

Caution

Proper Resistance: To prevent rapid dissipation of any static charge and to protect service personnel from electric shock, a minimum of 1M

(Megohm) series resistance is required between service personnel and the ground connection. Many commercial products meet this requirement; any of these are acceptable. Please consult Nuera if additional information is required.

110

ORCA Gateway Maintenance

Gateway Status

It is possible for all ORCA card modules to be removed and replaced without disconnecting power to the gateway.

Dual CM clusters are present in a chassis to guard against a service outage. Upon detection of a failed module in a control cluster, the UPM3/UPM4 and HST cards automatically switch to the backup control cluster.

Because each control cluster includes a HUB2 and a HUB2X card, the ORCA gateway provides dual 100Base-T buses to ensure redundancy in the event of a 100Base-T failure on the primary cluster’s HUB2/HUB2X.

You can monitor module operation in three ways:

• ORCA network management system

• SNMP trap monitoring

• LED indicators

The first alternative requires the use of the Nuera Configurator, which is included with your gateway purchase. The second requires NueraView, a more advanced software tool.

For more information on using either software package, refer to the software manual.

Card LED Indicators

This section describes the LED indicators that appear on

ORCA gateway modules. For more information on ORCA alarm and status indicators, see the software manual.

All ORCA gateway modules (HUB2, HUB2X, CM, CMX,

UPM3, UPM4, HST, and HSTX) have LEDs that signal the operational condition of the associated card. These LEDs

111

ORCA Gateway Hardware Manual

and their associated conditions are described in Table 5,

“LEDs: All Cards,” on page 136.

Power Module LED Indicators

The ORCA power module provides two (one on the 8-slot chassis) front-panel status LEDs that indicate power input and output condition. A green output LED indicates that the power module output is in regulation. A red LED indicates a power supply malfunction. If neither LED is lit, the power module has lost connection to its main power feed.

Fan Module LED Indicators

ORCA fan modules are equipped with a front-panel, twocolor LED status indicator. Normal function displays a green LED indication. A red LED indicates that the fan is not rotating. If neither LED is lit, the fan module has lost connection to the power supply rail.

Power Module Maintenance

21-Slot Chassis Power Modules

Two power modules are installed at the bottom of an ORCA

21-slot chassis (see Figure 35 on page 113). In normal operation, the power load is shared equally by both power modules. Each module is designed to individually sustain power to the ORCA gateway in case one power module fails.

Either module can be removed by switching module power

Off, disengaging the locking handle, and pulling directly out from the front of the 21-slot chassis. As a safety precaution, the locking handle is designed to force the module power switch to its Off (0) position.

To fully disengage the ORCA gateway from all power, it is necessary to disconnect the power connections from the back of the chassis. This is only required when all current must be removed from the gateway.

Hot-Swap Procedure

Once you have received notification of a power supply failure, either through NueraView, the Nuera Configurator, or by observing the red (Alarm) LED, use the following procedure to remove the faulty supply and insert a new power unit into the system.

Caution

Caution

Disconnect power from the faulted power module by moving the ganged dual power switch to its Off (0) position.

Energy hazards exist at the rear of the power bay. Avoid making contact.

113

ORCA Gateway Hardware Manual

1. Ensure that power is disconnected from the faulted power module by moving the ganged dual power switch to its Off (0) position. As a safety precaution, the locking handle is designed to force the module power switch to its Off (0) position.

2. Disengage the spring-loaded locking handle by pushing the top of the handle vertically downward to release the locking mechanism. Rotate the handle outward, releasing the power module from its locked position.

3. Firmly grasp the faulty power module by its disengaged locking handle and remove it half-way by pulling straight outward.

Caution

The power supply is heavy. Make sure to support the bottom of the power supply while pulling the unit out of the chassis.

4. Move locking handle back to its locked (detent) position, and slide the power module out of the ORCA chassis.

5. With its locking handle disengaged, align the replacement power module in its guide slots and slide inward to engage its rear guide pins.

6. Engage locking handle.

7. Apply power to the replacement power module by moving its ganged dual power switch to its On (1) position.

8. Verify that the replacement power module displays a green LED.

Cleaning the Power Supply Fan Filter

ORCA gateway air filters must be cleaned periodically to ensure continued adequate air flow. In a normal environment, the filter should be cleaned at least every six months.

In a high-dust environment, it may have to be cleaned as often as once every month. If the air filter is not properly maintained, it may clog the air flow and cause the power supply to overheat and to shut down.

114

ORCA Gateway Maintenance

To clean the air filter, refer to Figure 36 and perform the following steps:

Figure 36. Servicing the Power Supply Air Filter

1. Be careful not to dislodge particles into the unit when removing the air filter (described in step 2).

2. Remove the air filter from the unit by snapping the filter housing off the back of the unit and removing the filter from the housing.

3. Wash the air filter in a solution of mild detergent and water.

4. Allow the filter to dry, reinstall it in the housing, and reattach the housing by pressing it back into the rear of the unit.

8-Slot Chassis Power Modules

A maximum of four, minimum of two power modules are installed at the top of an ORCA 8-slot chassis. In normal operation, the power load is shared equally by all the modules. The 8-slot chassis is designed to run on four power supplies. To have a fully redundant system, all four power supplies must be installed.

Any of the modules can be removed by loosening the screws and first pushing on the black extraction lever, then pulling it straight out to pry the module out of its housing.

Hot-Swap Procedure

Once you have received notification of a power supply failure by observing the red (Alarm) LED, remove the faulty supply and insert a new power unit into the system, following the directions above. It is neither necessary nor recommended that you disconnect power from the rear of the power bay. Verify that the replacement power module displays a green LED.

Fan Module Maintenance

21-Slot Chassis Ventilation

Given the complexity of the internal circuitry of an ORCA gateway, maintaining operating temperatures within acceptable levels is critical. Cooling is provided by two fan modules at the top of the ORCA gateway, which cool the card modules, and by integral fans within the two power supplies. Ensure that air intake and exhaust areas are never obstructed during gateway operation.

117

Caution

Removing an ORCA gateway fan module alters the airflow characteristics of the ORCA gateway chassis. Operating an

ORCA gateway in this condition can cause overheating. To avoid potential damage or loss of service, ensure that fan removal or replacement is performed in less than five minutes.

1. Ensure that the replacement fan module is ready for insertion.

2. Turn the four captive thumbscrews on the failed module counter-clockwise to disengage locking tabs.

3. Remove the failed fan module by grasping its handle and pulling straight outward.

4. Align replacement fan module in its guide slot and gently slide it inward to engage its rear guide pins.

ORCA 8-slot chassis fan trays are equipped with a frontpanel, bi-color LED status indicator. Normal function displays a green LED indication. A red LED indicates that one or more of the fans in the tray are not rotating. If the LED is not lit, the fan module has lost connection to the -12V power supply rail.

Hot-Swap Procedure

Once you have received notification of a fan tray failure by observing the red (Alarm) LED, remove the faulty fan tray and insert a new fan tray in the system, following the directions above.

Note

Individual fan components of the fan tray cannot be fixed or replaced by the user. If any component of the fan tray fails, the entire tray must be replaced. Faulty fan trays can be sent back to Nuera to be serviced.

Caution

Removing an ORCA 8-slot fan tray alters the airflow characteristics of the ORCA 8-slot chassis. Operating an ORCA gateway in this condition can cause overheating. To avoid potential damage or loss of service, ensure that fan removal or replacement is performed in less than five minutes.

ORCA Gateway Maintenance

Card Maintenance

This section explains how to install, remove, and hot-swap

ORCA gateway cards (modules). It also covers how to move configured CM cards between active gateways.

Caution

The HUB2X-1000Base-SX is a Class 1 laser product.

Do not stare directly into the laser beam or view it directly with optical instruments.

Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures.

Unterminated optical connectors can emit invisible laser radiation. The lens in the human eye focuses all the laser power on the retina, so even a low power laser could permanently damage the eye if it is focused directly on the laser source.

Installing Cards

ORCA gateway cards are designed to fit snugly within the chassis. This ensures that, once installed, card modules remain in place and provide reliable service in the most demanding environments.

When placing a card into the chassis, use the following procedures.

Note

When installing new cards, it is recommended that the cards be installed into the card slots in an incremental fashion, rather than randomly staggering the cards throughout the chassis.

121

ORCA Gateway Hardware Manual

Front Card Installation

1. Ensure the black ejector tabs at the front of the replacement card are in the unlocked position as shown in Figure 40.

Figure 40. Ejector Tabs in Unlocked Position

2. Place the bottom edge of the card into the bottom card guide slot. Notice the metal ESD clip shown in Figure 42 on page 124 located approximately.5” (12mm) from the opening of the channel. The edge of the card must be inserted into the channel outbound of this clip.

3. Place the top edge of the card into the corresponding top card guide slot as shown in Figure 41 on page 123.

122

ORCA Gateway Maintenance

Figure 41. Aligning Card in Guide Slot

4. Gently push and pull the card in an up-and-down rocking motion. (Do NOT move the card from side to side.

This action may damage the card.) The leading edge of the card must slide in its guide slots past the ESD clip located in the bottom guide slot and into the chassis toward the midplane. See Figure 42 on page 124.

Rear Card Installation

Use the same procedure presented in “Front Card Installation” on page 122; however, be aware that the top and bottom guide slots for rear-mounted cards do not have ESD clips. Be sure to reconnect rear card cabling after module replacement.

ORCA Gateway Maintenance

Removing Cards

Caution

When removing ORCA gateway card modules, ensure that the module’s top and bottom captive anchor screws are completely loose. Do not use force when installing or removing

ORCA cards. The precise tolerances require that you use finesse rather than excessive force!

To remove either a front or rear card from an ORCA gateway chassis, use the following procedure and observe the following precautions:

• If the card to be removed is a rear card, you must disconnect its cabling prior to removal.

• Ensure that the module’s top and bottom captive anchor screws are completely loose.

• Set the ejector tabs to the open position.

1. Use a small screwdriver to loosen the upper and lower captive anchor screws located behind the upper and lower ejection tabs of the card to be replaced. Screw location is shown in Figure 45 on page 128.

127

ORCA Gateway Hardware Manual

Captive Screws

Figure 45. Locating Upper and Lower Captive Screws (Lower Shown)

2. Eject the card to be replaced by pushing both ejector tabs vertically outward until the card disengages from the midplane.

3. Because the side-by-side positioning of the cards in the chassis prevents you from grasping the card by its backplane, you must pull the card out using its ejector tabs.

See Figure 46 on page 129.

128

ORCA Gateway Maintenance

Caution

Figure 46. Removing Card

Do NOT rock the card in the card channel. Use equal force on the top and bottom ejector tabs and pull the card straight out of the chassis.

Swapping CM Cards Between Gateways

Whenever you move a Control Module (CM) card from one

ORCA gateway chassis within your application to another

ORCA gateway chassis, the new chassis will have a different shelf ID. This causes a shelf ID mismatch to occur. This section provides information about what you must do to resolve this situation.

Standby Mode

If a CM card with a shelf ID mismatch arbitrates to standby mode in a new chassis, its configuration is automatically ini-

129

ORCA Gateway Hardware Manual

tialized (storage initialization), its flash memory is updated with the current shelf ID, and it registers with the active

CM card in the new chassis. Therefore in this instance, you do not need to make any modifications.

Active Mode

If a CM card with a shelf ID mismatch arbitrates to active mode in a new chassis, it will not perform the following tasks:

• Activate the ethernet connection

• Register UPM3/UPM4 modules or the standby CM module

• Communicate with the network management system

LED Alarm Indication

In this situation, the console port runs, and the LEDs flash a pattern to indicate this non-functional mode. The LEDs alternate between the two following flash patterns:

• Red On, Green Off, Yellow On

• Red Off, Green On, Yellow Off

Clearing the Alarm

To clear this alarm mode:

1. Connect a PC to the console port located on the ORCA

CMX module.

2. Launch a terminal communications program.

3. From the console prompt, enter a valid decimal IP address for the card:

ETHERNET IP nnn.nnn.nnn.nnn

Note

You can reassign the current IP address or use a new one.

130

Note

ORCA Gateway Maintenance

4. You will be prompted to proceed. Answer yes to continue, or no to cancel. Be aware that continuing will erase any configuration information currently held in the CM module.

5. Wait until prompted, then turn off power to the ORCA gateway, and turn it back on.

The IP addresses of the UPM3/UPM4s and Standby CM are cleared and automatically reassigned based on their slot location. For example, the IP address of the UPM3/

UPM4 in slot 3 is assigned as Active CM IP address +1; the UPM3/UPM4 in Slot 4 is assigned as Active CM IP

address +2. The Standby CM IP address is assigned as

Active CM IP address +12.

When the IP address is updated and a shelf ID mismatch exists, the configuration is automatically initialized, and the flash memory is updated with the current shelf ID.

If two CM cards reside in the new chassis when the gateway is turned on, and one possesses the current shelf ID and the other does not, the one with the current shelf ID arbitrates to active mode, and the other arbitrates to standby mode.

For more information about alarms, see the software manual provided with the gateway.

Hot-Swapping Cards

An ORCA gateway module can be hot-swapped when its blue LED is lit. Failed boards indicate “blue” by an automatic, software-controlled process that systematically removes them from service. ORCA gateway modules can also be forced “blue” by invoking an NMS-controlled command called Virtual Eject. ORCA gateway modules can also be forced “blue” by disengaging the lower ejection tab on the module.

Forcing a module “blue” using the ejection tabs will affect service.

131

ORCA Gateway Hardware Manual

Once you have received notification of a board failure, either through the NMS or by observing the blue LED, use the following procedure to remove the faulty card and insert a new

card into the system. See "Removing Cards" on page 127 for

more information.

Caution

This procedure involves handling electrostatic sensitive devices. Special care must be taken to avoid damage. Observe the following precautions:

• Use a grounded wrist strap when handling the module

• Avoid touching circuitry or conductive components.

• Place the module on an anti-static mat once it is removed from the chassis.

• Use an approved anti-static bag and shipping container

1. Connect a grounding wrist strap attached to your wrist to the ESD connector located on the back right position of the ORCA gateway chassis.

2. Loosen the set screw for the module to be removed

3. Flip the lower ejector tab on the failed module, or issue the Virtual Eject command from the NMS. Ensure that the module to be replaced shows a blue LED indication.

4. For rear cards, use a small screw driver to loosen all cable anchor screws from existing connectors and disconnect all cables from the module, if any.

5. Disengage both ejection tabs from the module to be replaced.

6. Slide the module straight outward, and place in an antistatic container or on a grounded work surface.

7. Remove the replacement module from its anti-static container.

8. Carefully align the replacement module into its guide slots in the ORCA gateway chassis, and insert it gently to engage the rear guide pins.

132

ORCA Gateway Maintenance

9. Move both ejector tabs to their locked position and tighten the set screws.

10. Reconnect all cables to their proper connectors.

11. Fasten all cable anchor screws.

12. Remove wrist strap.

If a slot configuration exists for the slot containing the replacement module, the module is programmed automatically. Its LEDs transition in sequence from blue, yellow

(Power On Self Test), red (if no configuration exists), to green (online).

After replacement, if no configuration exists for the slot, the module indicates red (present, but not configured). Use the gateway NMS to configure the slot and render the module online.

Upgrading an ORCA Gateway

Upgrading an ORCA gateway generally requires the use of the Nuera Configurator or NueraView. Upgrading procedures that involve these software packages are found in your software manual.

Specific release upgrade procedures may be found in the release notes on the Nuera CD.

Upgrading the Embedded Code

The embedded code is the software that resides on the card modules, the software that runs the ORCA gateway. When this software needs to be updated, the new embedded code must be downloaded from a networked PC through the

Nuera Configurator or NueraView. The embedded code is first downloaded to the CM modules, then propagated to the

UPM and HST modules from the CM modules. This process

133

ORCA Gateway Hardware Manual

is called “downloading code.” The exact procedure is found in the accompanying software manual.

Nuera handles embedded code upgrades in a number of different ways. Usually updates are available through the

Nuera Communications website, while point-release upgrades are on CD only. Contact your Nuera representative upgrade to the latest version of embedded code.

Upgrading Card Modules

To upgrade an ORCA gateway’s card modules, you will need the new card, compatible embedded software, and upgraded

Nuera Configurator or NueraView software. Check the software manual for the current hardware and software dependances.

To install the new card, follow the procedures in “Card

Maintenance” on page 121 to insert the card into the chas-

sis. The card will not be recognized by the system until the embedded code is upgraded. The procedure for upgrading the embedded code is in the software manual. Then, to configure the card, the configuration software, Nuera Configurator or NueraView, must be updated. This procedure is also in the software manual. Check with your Nuera representative to acquire the correct components and software.

21-slot Chassis Specifications

Voice

Channels Echo Cancellation

Each voice channel in an ORCA gateway system meets or exceeds ITU G.168 recommendations for near-end echoes delayed by up to 54ms. The exceptions to G.168 are throughput delay, phase reversal, and tone disabler.

The echo canceller provides approximately 40dB of echo attenuation. The residual echo is further attenuated to imperceptible levels by a non-linear processing function.

This is also referred to as NLP, center clipper, or residual echo suppressor. The NLP as well as the echo canceller can be disabled via configuration without interruption of voice processing.

Performance of an echo canceller is also a function of the echo return loss (ERL) provided by the 2-wire/4-wire hybrid. The echo canceller can operate with ERL values as low as 6dB. Typical convergence time of the echo canceller is less than 1 second and occurs at the beginning of the first active speech interval.

Signaling

Currently supports out-of-band signaling.

Voice Levels

Supports Rx and Tx gain adjustments on all voice channels from -16 db to +7 db.

The voice ports on the gateway can use automatic gain control on a port-by-port basis. When enabled, the gain on each port is kept in the optimum range of the vocoder to provide optimal voice quality.

Fax III

Supports Group III FAX protocols V.17, V.21, V.27, and

8-slot Chassis Specifications

Voice

Channels Echo Cancellation

Each voice channel in an ORCA gateway system meets or exceeds ITU G.168 recommendations for near-end echoes delayed by up to 54ms. The exceptions to G.165 are throughput delay, phase reversal, and tone disabler.

The echo canceller provides approximately 40dB of echo attenuation. The residual echo is further attenuated to imperceptible levels by a non-linear processing function.

This is also referred to as NLP, center clipper, or residual echo suppressor. The NLP as well as the echo canceller can be disabled via configuration without interruption of voice processing.

Performance of an echo canceller is also a function of the echo return loss (ERL) provided by the 2-wire/4-wire hybrid. The echo canceller can operate with ERL values as low as 6dB. Typical convergence time of the echo canceller is less than 1 second and occurs at the beginning of the first active speech interval.

Signaling

GR-303, V5.2, NCS.

149

ORCA Gateway Hardware Manual

Voice Levels

Supports Rx and Tx gain adjustments on all voice channels from -16 db to +7 db.

The voice ports can use automatic gain control on a portby-port basis. When enabled, the ports input are kept in the optimum range of the vocoder to provide optimal voice quality.

Fax III

Supports Group III FAX protocols V.17, V.21, V.27, and

V.29 at baud rates up to 14.4 Kbps. Maximum FAX rate can be configured independently of the voice rate.The maximum rate is selectable by the user. Supports auto fallback, and tolerates network delays of up to 1 second.

Voice

Compression

ORCA units use silence suppression and low-bit-rate voice

(LBRV) compression techniques to achieve compression ratios as high as 20:1. BTX-Series units support the voice compression algorithms on a per-channel basis shown in

IBLIOGRAPHY

This appendix provides a brief, annotated bibliography of publications that provide information relevant to the understanding of the design and management of the ORCA communications platform.

Hardware Specifications

“CompactPCI 2.0, R2.1 cPCI Specification”, PICMG. Rogers Communications, Wakefield, MA, September, 1997.

CompactPCI is a high-performance industrial computer platform based on the standard PCI electrical specification in rugged Eurocard packaging, with a high-quality 2mm metric pin and socket connector.

CompactPCI is suited for telecommunications, computer telephony, real-time machine control, industrial automation, real-time data acquisition, instrumentation, military systems and other applications requiring high speed computing and modular and robust packaging design. The CompactPCI specification defines both 3U (100 x 160mm) and

6U (233 x 160mm) card formats for modular, rack-based systems.

Version 2.1 incorporates many additions and clarifications over the previous Version 1.0 that was released in November 1995. Enhancements in the CompactPCI 2.1 specification include:

• Clarified/corrected interrupt routing

• IEEE1101.10 enhanced Eurocard mechanics

• Adoption of a consistent method for rear panel I/O connections as defined by the IEEE 1101.11 Draft specification

191

ORCA Gateway Hardware Manual

• Rear panel I/O drawings and pin assignments provided

• Geographic addressing defined that allows a card to read its slot ID

• Physical vs. logical slot addresses defined

• The concept of bus segments vs. backplanes

• Pull-up resistor now required on boards implementing

GNT#

• Backplane and board decoupling requirements clarified

• Backplane termination requirements illustrated

• Updated mechanical drawings

• Dedicated clock routing and other provisions for future hot swap

• 32-bit trace lengths for 64-bit and 32-bit systems

Revision 2.1 of the specification provides features useful to telecom, including geographic addressing, standardized rear panel I/O connection methods, and mechanics that address tough international safety and emissions standards.

“CompactPCI 2.1, R1.0 cPCI Hot Swap Specification”, PICMG.

Rogers Communications, Wakefield, MA, August, 1998.

This document details how to implement the "hot swapping" of components in CompactPCI systems; that is, the capability of removing and replacing components without turning off the system. Hot Swap capability is increasingly important in systems used for applications such as telecommunications, which require that the system be operational at some level continuously. CompactPCI is a high-performance industrial computer platform based on the standard PCI electrical specification in rugged Eurocard packaging, with a high-quality 2mm metric pin and socket connector.

The new CompactPCI Hot Swap Specification defines pin sequencing and other enabling hardware technologies, as well as the software architecture required to support live insertion and extraction of boards in a running CompactPCI system. The new specification was approved in July 1998 by

PICMG's Executive membership. Copies are presently being distributed to all members of the organization.

192

Bibliography

The Hot Swap specification is also available to non-members for a nominal fee

The Hot Swap Specification provides a framework for designing CompactPCI Hot Swap components (boards, backplanes, ICs, platforms, etc.). This framework gives vendors some flexibility to choose the features appropriate for their products, and still operate with all other CompactPCI components (Hot Swap and non-Hot Swap).

“CompactPCI 2.5 R1.0 cPCI Computer Telephony Specification”,

PICMG. Rogers Communications, Wakefield, MA, April, 1998.

This document defines the utilization of CompactPCI userdefinable pins for the computer telephony functions of a standard TDM (Time Division Multiplexed) bus, telephony rear I/O, 48 Volts DC and ringing distribution in a 6U chassis environment. CompactPCI is a high-performance industrial computer platform based on the standard PCI electrical specification in rugged Eurocard packaging, with a highquality 2mm metric pin and socket connector.

The Computer Telephony Specification extends the capabilities of the CompactPCI architecture to support specific application needs of the industry:

• Hot swappable TDM bus on J4 complying with the ECTF

H.110 specification

• Two and four wire I/O of J5 for analog and digital telephony

• Frame grounding techniques based on IEEE 1101.11

• Sub-bus and front panel keying

• Geographical slot addressing and shelf enumeration

This specification provides guidance for backplane/chassis vendors, CT card vendors, and CT system integrators, so as to promote multi-vendor interoperability and the design of open, standards based components and systems.
