November 2003 xi Preface xii 1000-A2-GB20-10 November 2003 C H A P T E R 1 Voice-over-Broadband Networking This chapter describes Jetstream Voice-over-Broadband (VoBB) local access network architecture and the role of the CPX-1000 Voice Services Platform, including the following topics: „ Local access network architecture (page 1-1) „ CPX-1000 Voice Services Platform (page 1-3) „ Packet network configuration (page 1-4) „ Call origination and completion (page 1-6) „ CPX-1000 calling features (page 1-10) „ Local access network management (page 1-11) Local Access Network Architecture November 2003 The modern packet-based local access network enables Integrated Communication Providers (ICPs) to deliver a combination of voice and data services to their subscribers over the local loop. The available Jetstream VoBB local access network alternatives (Figure 1–1) include the following: 1. Voice over DSL (VoDSL) — Jetstream VoDSL enables the delivery of integrated high-speed voice and data services over a single DSL circuit; that is, over a single copper pair. 2. Voice over E1 (VoE1) — A VoE1 solution offers access at greater distances (i.e., hundreds of miles when repeaters are used) and provides guaranteed bandwidth. It also uses existing E1 aggregation resources at the ILEC central office. 3. Voice over Wireless (VoWLL) — Jetstream VoWLL eliminates the need for land line copper loops by using ATM over MMDS or U-NII wireless broadband access networks. 1-1 Voice-over-Broadband Networking 1000-A2-GB20-10 Regional Switching Center PSTN ATM E1 ATM/F rame E1/DS 3/STM -1 Access Multiplexer VoE1 IAD Wiring Centers e am /Fr ATM E1 VoDSL IAD e am /Fr ATM L xDS 2 V5.

Voice-over-Broadband Local Access Networks The CPX-1000 Voice Services Platform is a large-scale voice platform that resides in an ICP’s Regional Switching Center (RSC). It serves as the gateway between an ICP’s existing Class 5 voice switch and a packet-based local access network (Figure 1–2).

Voice-over-Broadband Network Architecture 1-2 November 2003 1000-A2-GB20-10 Voice-over-Broadband Networking The CPX-1000 Voice Services Platform architecture achieves seamless integration of voice and data networks. These networks comprise standard ATM switches and local access multiplexers available from multiple equipment manufacturers, as well as components provided by Paradyne. There are two available Jetstream components—the Integrated Access Devices (IADs) and the CPX-1000. The IADs, supplied by Paradyne and other manufacturers, reside at the subscriber premises. Each IAD provides dial tone to standard (POTS) local telephones and data service, using a single transmission link. The network architecture enables ICPs to extend local dial tone services from an existing Class 5 switch over a packet-based access network. From this perspective, as a loop extender, voice-overbroadband is functionally similar to traditional Digital Loop Carrier (DLC) equipment, where the Class 5 switch provides the actual dial tone, as well as Custom Local Area Signaling Services (CLASS) and calling features. However, unlike traditional DLCs, which supply the physical subscriber line interface at the central office, the packet architecture places that interface at the subscriber premises. The benefits of this architecture are: „ better voice quality, by performing analog-to-digital conversion near the phone „ more efficient use of copper connections between the subscriber premises and the Class 5 switch CPX-1000 Voice Services Platform The CPX-1000 Voice Services Platform supports any broadband access network technology, including voice-over-E1, voice-overDSL, and voice-over-wireless local loop (Figure 1–1 on page 1-2). The CPX-1000 is a carrier-class, rack-mounted shelf (21-inches high by 17-inches deep) with redundant components. The CPX-1000 incorporates a scalable architecture in a single shelf, or multiple CPX-1000 shelves in a rack. „ A single shelf can support additional subscribers by adding more network modules or using the space capacity of existing network modules. November 2003 1-3 Voice-over-Broadband Networking 1000-A2-GB20-10 „ Multi-shelf equipment is comprised of more than one CPX-1000 Voice Services Platform when the capacity (provided by a single shelf) is exceeded. Most shelf components are modules comprised of a line card and a transition card. The line card installs in the front of the CPX-1000 and the transition card installs in the rear to minimize downtime during repair or maintenance. A passive midplane within the CPX-1000 shelf connects the line cards and transition cards. Packet Network Configuration The CPX-1000 Voice Services Platform transports voice traffic via an ATM network. When Frame Relay is used, the Frame Relay frames are encapsulated in ATM cells. In the packet network (Figure 1–3), voice-over-broadband requires a minimum of two Permanent Virtual Circuits (PVCs) across the network for each IAD (in both ATM and Frame Relay networks). „ The first PVC transports the voice and management traffic associated with all of the subscriber's telephone lines. The voice PVC is configured as a variable bit rate-real time (VBR-rt) PVC, and has priority over the data PVC. „ The second PVC transports the data traffic. The data PVC is typically set up as an unspecified bit rate (UBR) PVC. Voice is more sensitive to network latency than data, so this configuration ensures that voice traffic always has priority over data. However, this configuration also enables voice traffic to consume bandwidth when a call is in progress. Typically, few subscriber's telephone lines are simultaneously in use, so the majority of the bandwidth is usually available for data service. For example, over a single 768 Kbps symmetric DSL connection, an ICP supports up to eight simultaneous telephone calls using 2:1 compression serving a IAD with 32 extensions at a P.01 grade of service and still deliver data service at an average speed of 550 Kbps (Figure 1–4). 1-4 November 2003 1000-A2-GB20-10 Voice-over-Broadband Networking Phone Sys I AD Local Loop LAN Phone Sys PVC LAN ILEC CO CPX1000 Class 5 Voice Switch PSTN PVC Data I AD e Voic ATM Access MUX Packet Switch Phone Sys Internet I AD 0250 LAN Voice DLCI Frame Relay Access MUX Phone Sys Data DLCI FRF8 IWF I AD LAN ICP RSC ILEC CO Subscribers Figure 1–3.

Bandwidth Usage of a 768 Kbps SDSL Circuit November 2003 1-5 Voice-over-Broadband Networking 1000-A2-GB20-10 Many network operators have Frame Relay-based local access networks that are interconnected with ATM networks. The CPX-1000 Voice Services Platform can interface with the Frame Relay network through an Interworking Function (IWF) between the Frame Relay and ATM (Figure 1–3 on page 1-5). The IWF is an industry-standard function that either the access mux or a Frame Relay/ATM switch can execute. In a Frame Relay network, each PVC uses an identifying Data Link Connection Identifier (DLCI). ATM PVCs, however, use a Virtual Path Identifier/Virtual Channel Identifier (VPI/VCI). The IWF maps each Frame Relay DLCI to a corresponding ATM VPI/VCI. This association between the Frame Relay DLCI and ATM VPI/ VCI is made when provisioning PVCs. Call Origination and Completion The following describes the network interaction when a subscriber initiates a call (Figure 1–5): 1. A subscriber initiates the call by taking a telephone off-hook. 2. The IAD notifies the CPX-1000 Voice Services Platform through the Common Channel Signaling (CCS) channel in the voice PVC. 3. The CPX-1000 sends an outgoing call request message to the Class 5 switch through the PSTN establish protocol on the V5 interface. 4. The Class 5 switch selects an available E1 time slot in the V5 interface group. It directs the CPX-1000 via the V5 BCC protocol to connect this time-slot to the IAD subscriber port. 5. The CPX-1000 cuts the calling station at the IAD through to the Class 5 switch. 6. The Class 5 switch provides dial tone. 7. The subscriber dials the destination number and the Class 5 switch collects DTMF digits. 8. The Class 5 switch routes the call, returns the call progress, and generates a call data record. 9. The CPX-1000 notifies the Class 5 switch when the station hangs up. 10.The class 5 switch directs the CPX to disconnect the timeslots via the V5 BCC protocol, taking down the call. 1-6 November 2003 1000-A2-GB20-10 Telephone Voice-over-Broadband Networking IAD CPX-1000 Class 5 Switch 1 2 3 4 5 5 5 7 7 7 8 PSTN 9 0437 Figure 1–5.

The Class 5 switch assigns a time slot via the V5 BCC protocol. 2. The CPX-1000 sends a setup message to the IAD, verifying both bandwidth and port availability. 3. The CPX-1000 Voice Services Platform connects the specified time slot to an IAD port. 4. The Class 5 switch sends an incoming call request message to the CPX-1000 through the PSTN protocol on the V5 interface. 5. The IAD initiates ringing. 6. The IAD notifies the Class 5 switch via the CPX-1000 Voice Services Platform when the first ring is complete. 7. The Class 5 switch sends the caller ID information in band to the IAD via the CPX-1000, and then sends the signal to continue ringing. 8. When the station answers, the CPX-1000 sends an off-hook notification to the Class 5 switch. 9. The Class 5 switch notifies the CPX-1000 when the call is cleared. 10. The CPX-1000 notifies the Class 5 switch when the station hangs up. 11. The class 5 switch directs the CPX to disconnect the timeslots via the V5 BCC protocol, taking down the call. 1-8 November 2003 1000-A2-GB20-10 Telephone Voice-over-Broadband Networking IAD CPX-1000 Class 5 Switch 1 PSTN 2 3 4 5 6 6 6 7 7 8 8 8 10 9 10 10 0353 Figure 1–6.

CPX-1000 (Front View) 2-2 November 2003 1000-A2-GB20-10 Equipment Operational Features CPX-1000 Voice Services Platform Description A single CPX-1000 Voice Services Platform can manage more than 8,000 subscriber telephone lines (for 8:1 concentrations) on a voiceover-broadband network, including: „ Circuit-to-packet conversion—converts DS0s from the Class 5 switch into cell-based ATM format. „ Routing—routes cells to and from appropriate IADs at subscriber locations. „ Call administration—manages call-control signaling to both the Class 5 switch and the IADs. „ Traffic management—monitors the connection over the access network to each end user. „ Concentration management—supports line concentration levels up to 40:1. „ Administration—acts as the administrative platform for managing voice-over-packet services. Traffic Capacity The CPX-1000 supports up to 2,000 IADs and supports two types of E1 modules, which may be used interchangeably. „ The Octal E1 module provides eight E1 ports; up to six Octal E1 modules may be placed in the CPX-1000. Echo Cancellation (EC) and Echo Cancellation And Compression (ECAC) are provided on separate modules. „ The 12-port E1 ECAC module provides 12 E1 ports. Up to six modules can be placed in the CPX-1000. Echo Cancellation And Compression is provided directly onboard, eliminating the need for separate EC or ECAC modules. The capacity of the CPX-1000 shelf depends on the shelf configuration and the concentration and redundancy options selected. For business telephone service with standard 4:1 line concentration, a single CPX-1000 shelf using 12-port E1 with STM-1 OC-3 can support over 2,000 simultaneous calls and 8,000 business (4:1) or 16,000 residential (8:1) subscriber lines. Carriers can upgrade the CPX-1000 network by adding additional shelves, all of which can be managed by a single JetVision workstation.

The MP supports the following: „ Configuration, fault, and security management for the CPX-1000 „ Configuration management, fault management, and remote software upgrade of the IADs „ High-performance, memory-resident database for persistent configuration „ Real-time performance and error statics Call Processing The Call Processor Engine manages the connections between the CPX-1000 shelf and the IADs at subscriber premises. The Call Processor Engine resides on the redundant Call Processor (CP) modules that handle call processing, call-control signaling, call setup, and call tear-down. The V5 call handling processes on the CP modules receive all call control and Interface signaling from the Class 5 switch using the V5 data link protocol. The IAD Signaling and Connectivity function manages communication between the CPX-1000 and the IADs. The information passed between the CPX-1000 and each IAD includes common channel signaling, alarms and events, and software downloads. November 2003 2-7 CPX-1000 Voice Services Platform Description PSTN Interface 1000-A2-GB20-10 The PSTN interface connects the CPX-1000 to the Class 5 switch via E1 lines. The Port Controller inserts framing and supervision signals into the TDM data stream. The PSTN interface then directs all signaling to the V5 call handling process and the CP. The PSTN interface controls all time slot mapping and CP functions. The PSTN interface routes all voice timeslots over the voice bus to the packet interface. The Voice Processing function switches individual timeslots between the E1 ports and the voice bus. The Voice Processing function maps all incoming and outgoing voice data streams. The CPX-1000 supports up to 4,096 unique PVCs (each representing one IAD). Each PVC (i.e., IAD) has a unique VPI and VCI assigned to it. The CPX-1000 supports 256 VPIs in the range of 0 to 255. IADs can be provisioned on any of these VPIs. The permissible range of VCIs per VPI is 0 to 1023. The maximum number of VCIs per VPI can be configured as one of five possible settings when the equipment is initially configured. The possible settings are: „ 1024 (default) „ 512 „ 256 „ 128 „ 64 Selection of the maximum of VCIs is determined by the network planner for what best fits the network topology. In order to afford the maximum number of PVCs available from the CPX-1000, IADs can be organized into IAD Groups. Groups are logical entities where IADs meet these criteria: „ provisioned with differing VPIs but the same VCI „ where the remainder of the following mathematical formula is the same for all IADs in the IAD group VPI (1024/VCIs per VPI) 2-8 November 2003 1000-A2-GB20-10 CPX-1000 Voice Services Platform Description For example, consider three IADs with the VPI/VCI pairs and where the maximum number of VCIs configured for the equipment is 256: A. 32, 100 B. 36, 100 C. 38, 100 1. All three have the same VCI. 2. The maximum number of VCIs possible (1024) divided by the number of VCIs configure (256) equals 4. 3. Pairs A and B yield a result with no remainder when their VPIs (32 and 36, respectively) are divided by the resultant of 1024 divided by 256: 32/4 = 8 with a remainder of 0 and 36/4=9 with a remainder of 0. (Pair C yields a different remainder: 38/4=9 with a remainder of 2, therefore, is not in the same group with A and B.) A maximum 2,000 IADs can be assigned to the same group, as determined by the above criteria. However, only 63 simultaneously active calls through IAD unlocked ports are allowed in any one IAD Group. Note IAD ports can be over-provisioned; however, only 63 can get dial tone at one time. Packet Interface The packet interface physically connects the CPX-1000 shelf to the packet network. The interface provides TDM data transport services over ATM using standard International Telecommunications Union (ITU) and ATM Forum-compliant communications protocols. This interface converts the information on the Bearer Bus to standard ATM cells and transmits these cells on the packet network. It also converts packet cells to voice timeslots. The Voice/ Control Splitter directs the ATM cells (which contain call control and signaling) through the IAD Signaling and Connectivity function to the Call Processor Engine.

The shelf mounts in a 19-inch Electronic Industries Association (EIA) rack mount platform. Reversible mounting flanges allow installation in a 23-inch rack. The CPX-1000 shelf is a forced-air cooled Network Equipment Building Standard (NEBS) Level 3-compliant platform with: „ 16-slot midplane „ DC power input panel „ Alarm panel „ Two hot-swappable power supplies The midplane is the interconnect for all 16 slots, power distribution, and alarm signal distribution. The CPX-1000 midplane accepts line cards, processing modules, and rear mounted transition modules. The power supplies (including integral fan assemblies) are located in slide positions below the card cage (accessible from the front of the shelf). System Alarm Panel The CPX-1000 alarm panel is located on the top front of the shelf. Indicators display the current operating status of the shelf and an alarm connector outputs to remote Telco alarm equipment (Figure 2–5). The CPX-1000 includes three types of indicators: „ Slot Status indicators for all 16 slots „ System Status indicator for system status „ Telco alarms Table 2–2 lists the color and status of each group.

The 12-port E1 ECAC module provides onboard echo cancellation and compression. Call Capacity and Redundancy When using Octal E1 cards, the CPX-1000’s call capacity is 1000 calls. When using 12-port E1 ECAC cards, the CPX-1000’s call capacity is 2000 calls. Each ATM card supports 1000 calls. Therefore, for ATM redundancy in a system with Octal E1 cards, two ATM cards are required and in a system with 12-port ECAC cards, four ATM cards are required. Slot Configuration Slots 6−10 are reserved for the following cards: „ MP card − Slot 6 „ CP cards − Slots 8 and 9 „ HSC cards − Slots 7 and 10 For populating the other cards in the chassis, it is recommended that you install the ATM cards and the PSTN cards on opposite ends of the chassis. For example, if you install the ATM cards in slots 1−4, then install the PSTN cards in slots 11−16. Install EC and ECAC cards near the PSTN cards. Module Configuration November 2003 The module configuration differs, depending on whether the CPX-1000 shelf is configured for STM-1 or DS-3 ATM. 2-13 CPX-1000 Voice Services Platform Description Call Processor Modules 1000-A2-GB20-10 The CPX-1000 shelf supports two CP modules, in an active/ standby configuration.

Call Processor Redundancy „ On power up, the primary CP (i.e., the CP in the lower numbered slot — slot 7) is the active CP and the secondary CP (i.e., the CP in the higher numbered slot — slot 9) is the standby CP. „ The active CP module handles all call processing activity, maintains all signaling, manages all IADs, captures all statistics and alarms, and monitors all hardware in the system. It passes all this information to the management system. 2-16 November 2003 1000-A2-GB20-10 CPX-1000 Voice Services Platform Description „ The standby CP module mirrors the state information of the active CP module (i.e., all of the activity on the active CP module) and can take over at any time. This architecture enables two types of CP module switchovers: „ Automatic switchover—the system detects a problem with the active CP module and performs a forced switchover to the standby CP module. Mechanisms used to detect problems with a CP module include: — Loss of a CP-to-MP (Management Processor) module heartbeat — Loss of a CP-to-CP module heartbeat — Failure of a CP to respond to an “are you alive” ping request from the High Availability software — Failure of the High Availability software to detect a ping request from the ping component on a CP module „ Administrative switchover—the network administrator initiates a CP switchover using JetCraft or JetVision. A forced switchover always goes through regardless of voice traffic and active cells remain up. Voice/Data Interruption Calls that are in setup process are lost during a forced switchover. Calls that are established and carrying voice traffic, however, survive a switchover. On a switchover, the old active CP’s activities are performed by the new active CP. After the switchover, the old active CP assumes the standby role (if all is well). CP switchovers do not automatically revert back. November 2003 2-17 CPX-1000 Voice Services Platform Description Management Processor Module 1000-A2-GB20-10 The Management Processor (MP) module is the administrative engine of a CPX-1000 shelf. It acts as a database for the shelf and as the administrative interface for JetCraft, JetVision and other management interfaces. The MP module consist of two cards (Figure 2–8): „ Management Processing card—contains the processor, volatile and non-volatile RAM, and interface connections for monitoring the redundant CP modules. „ MP Transition card—contains the I/O ports for connecting to the local area network and other peripheral devices. The MP module hosts the CPX Management Entity, which supports the following: „ CPX-1000 configuration, fault, and security management „ Configuration management, fault management, and remote software upgrade of the IADs „ High-performance, memory-resident database for configurations persistence „ Real-time performance and error statics Two Ethernet ports are provided on the MP Card. Each port provides one connection to the CP A and B modules, configured to run at 100BaseTX Full Duplex. Each Ethernet port supports 10BaseT, 10BaseT Full Duplex, 100BaseTX, and 100BaseTX Full Duplex media types. It can detect the network media type to which it is connected, when the AutoDetect mode is selected (recommended in most cases). On the MP Transition car also as 2 Ethernet connections. Ethernet 1 is enabled; Ethernet 2 is disabled. On the front of the MP is an Ethernet connection (“Ethernet”), which is the same as Ethernet 1 on the back. The back port is active, but the front Ethernet port is not active (unless there is no MP Transition card present). Table 2–5 lists the function of each control, port, and indicator.

The shared arrangement provides a backup E1 port to each E1 module should one of the IG groups fail. Caution Do not put primary and protecting E1 links on the same E1 module. Doing so prevents new calls from being made if one E1 module fails.

The ATM module performs real time circuit-to-packet conversion that allows an ATM-based access network to deliver local telephone service. The CPX-1000 protects the ATM connection to the packet network against physical facility failure and far end equipment failure. In a switchover scenario, the CPX-1000 executes the transition from the working to the protection port to ensure no services are disrupted. On power up, the presence of the ATM modules in the shelf is detected. Before ATM switchovers can occur, however, assigned, use JetCraft or JetVision to assign them to a protection group so that the primary and secondary modules can be designated. When the ATM modules are unlocked, the primary ATM module becomes active and the secondary ATM module becomes standby. This architecture enables two types of ATM module switchovers: „ Automatic switchover—the system detects a problem such as loss of signal and performs a forced switchover to the standby ATM module in the protection group. „ Administrative switchover—the network administrator initiates a CP switchover using JetCraft or JetVision. A forced switchover always goes through regardless of voice traffic and active cells remain up. Voice/Data Interruption Calls that are in the process of being set up are lost during a forced switchover. Calls that are established and carrying voice traffic, however, survive a switchover. The active and standby states for each ATM modules is persistent. The CPX-1000 continuously monitors the health of redundant ATM modules and switches over to the standby ATM module if instructed to do so by the software or user intervention. The CPX-1000 issues appropriate alarms and events to notify users that the switchover has been initiated and indicates the success or failure of each switchover. 2-28 November 2003 1000-A2-GB20-10 CPX-1000 Voice Services Platform Description STM-1 ATM Module CAUTION CLASS 1 LASER Use of controls, adjustment, or performance of procedures other than those specified herein may result in hazardous, invisible radiation exposure. The STM-1 version of the ATM module includes the processing card only (Figure 2–13). The ATM STM-1 module supports capacity for 155 Mbits of information and can handle 1,024 simultaneous calls (DS0s). Table 2–10 describes the controls, indicators, and ports on the STM-1 module. STM-1 redundancy uses 1 + 1 protection, with a primary port that is active in the normal operating state and a secondary port in the hot standby state. The secondary port takes over if the primary port loses its connection. Note Do not mix optical modes. If you are using single-mode STM-1 modules, use single-mode optical cables. If you are using multimode STM-1 modules, use multimode optical cables. Mismatching fiber cables may result in damage to the equipment.

The ATM DS3 module contains one DS3 interface to support 512 simultaneous calls (DS0s). Table 2–11 describes the controls, indicators, and ports on the DS-3 module. For DS3 protection, the CPX-1000 uses a Y-cable configuration. A DS3 splitter implements the Y-cable (Figure 2–15). Slots 11 and 12 are always used as the primary DS-3 modules and slots 13 and 14 are always used as the standby DS-3 modules. Figure 2–16 shows how the rear of the CPX-1000 shelf is cabled when there are: „ One primary and one standby DS-3 modules „ Two primary and two standby DS-3 modules When either the transmit or receive path on a DS-3 module fails, ATM processing switches over to the standby DS-3 module.

Echo Cancellation Module November 2003 2-35 CPX-1000 Voice Services Platform Description Echo Cancellation And Compression Module 1000-A2-GB20-10 The CPX-1000 supports an optional Echo Cancellation and Compression module with compression from zero to 100% of calls on the CPX-1000. When ADPCM compression is invoked, samples are packed two per byte (32 Kbps) or four per byte (16 Kbps). “Voice Compression” refers to the industry standard compression algorithm of the voice data passed between the CPX-1000 and an IAD. Voice data compression decreases the bandwidth used on the most narrow pipe (local loop) in the Unity architecture. Bandwidth reduction for voice enables additional voice calls and/or increased performance in data communications. ECAC Requirements „ ADPCM32 and ADPCM16 support „ Able to query compression capabilities „ Last two CPX-1000 slots available (typically slots 15 and 16) STATUS 0152 Figure 2–18.

JetCraft and JetVision possess common look-andfeel graphical user interfaces. Service providers may decide to use a combination of any of these applications to meet their deployment needs. For example, a service provider may decide to monitor its deployed CPX-1000s via the JetSNMP interface, while integrating its provisioning system to support the Jetstream platform via JetVision and JetWay. Table 3–1 compares the Jetstream network management systems. Table 3–1. Comparison of Jetstream Network Management Systems System Description JetCraft A Windows-based Craft Interface Terminal package that enables per-session management of a single CPX-1000 shelf at a time. JetVision A client-server based Element Management System that provides a persistent view of managed CPX-1000 equipment. JetVision can concurrently manage up to 50 CPX-1000s. JetVision is supported on both the Sun Solaris as well as Windows NT computing platforms. November 2003 3-1 Jetstream Management Systems 1000-A2-GB20-10 Table 3–1. Comparison of Jetstream Network Management Systems System Description JetWay JetWay is the northbound (also known as upstream) Applications Programming Interface (API) to JetVision. JetWay APIs enable integrated management systems to be developed and delivered into Network Management Systems used for provisioning, fault management, and performance management. JetWay is not available for this release. JetSNMP A CPX-1000 native interface enabling SNMP Managers (e.g., HP Open View) discovery and monitoring of CPX-1000 equipment. JetCraft JetCraft was developed for technical staff to perform on-site management functions, including CPX-1000 installation and troubleshooting during each session or instance. JetCraft can manage a single CPX-1000 shelf and its associated IADs at a time. JetCraft connects directly to a CPX-1000 shelf over a serial circuit or Ethernet, or remotely via a modem. It provides a Graphical User Interface (GUI) to simplify management activities. Each subscriber configuration is typically viewed separately. At the top level, a window displays the subscriber’s IAD and the active telephone ports on the IAD. You can add new subscribers or change items in a subscriber’s setup (such as activating telephone ports). 3-2 November 2003 1000-A2-GB20-10 Jetstream Management Systems Jetcraft enables the CPX-1000 to perform the following tasks: „ Gather version information „ Card discovery „ Redundancy decking „ Switchover „ Create and manage ATM protective groups „ User access management „ Statistics „ Provisioning database back up and restoration. Refer to Jetcraft User’s Guide for a detailed explanation of Jetcraft features and functionality. JetVision JetVision provides a full suite of management capabilities, as well as supporting interfaces to higher-level Network Management Systems (NMSs). The client-server architecture of JetVision supports multiple remote and local client sessions on Windows NT and Solaris platforms. The interface between JetVision and a managed CPX-1000 is a Common Object Request Broker Architecture (CORBA). JetVision provides a more robust (than JetCraft) graphical interface to manage CPX-1000s and IADs for configuration, fault reporting, troubleshooting, performance monitoring, and security. Each CPX-1000 contains a management agent that dynamically responds to the JetVision server management agent’s requests to execute management operations. These management operations include fault collection and reporting. November 2003 3-3 Jetstream Management Systems JetVision Managed Domains 1000-A2-GB20-10 A single JetVision can manage hundreds of thousands of subscriber telephone lines within its managed domain (Figure 3–1). The JetVision managed domain is composed of elements in the Jetstream voice-over-broadband (VoBB) network that are logically configured in JetVision or via JetWay, and are therefore manageable. A JetVision managed domain includes: „ CPX-1000 — MP card — CP card — TDM8E1 cards — ATM (STM-1 or DS-3) cards — Resource card (EC or ECAC) „ IADs JetCraft ATM/Frame Relay Network CORBA Agent IAD IAD Network Management System IAD Jetstream CPX-1000 IAD JetVision Client JetVision Client JetVision Client JetVision Server ATM/Frame Relay Network WAN CORBA Agent JetVision Client IAD IAD JetCraft IAD Jetstream CPX-1000 IAD 0275 Figure 3–1.
