END-TO-END NETWORK AND SUBSCRIBER MANAGEMENT

ZMS is a highly scalable platform that includes a comprehensive suite of applications that

deliver Fault, Configuration, Accounting, Performance, and Security (FCAPS) management

functions as well as subscriber account management. ZMS eliminates multiple management

layers allowing service providers to operate networks efficiently, to smoothly integrate man-

agement into Operations Support Systems (OSS), and to rapidly deploy new services.

As service providers respond to customer demand for broadband services, they require ways

to increase operations efficiency and eliminate subscriber activation backlogs. But with each

new service deployed, the provider must integrate the service throughout the network and

into another management system. If providers want true network efficiency and flow-through

provisioning, they must be able to easily deploy new network devices and launch new services

seamlessly into their current network environment.

ZMS does just that. As a robust single-seat management solution, ZMS deliv-

ers the entire range of Zhone broadband access products and management

services, and permits service providers to quickly measure, evaluate, and react

to network growth requirements.

ZMS is a standards-based, carrier-class network management solution that

provides service-to-subscriber management for all Zhone products. From

managing all Zhone local loop network elements (including Broadband

Access Node – BAN,™ Sechtor,™ and Z-Edge™), to truck-roll-free provision-

ing of services to new or existing subscribers, ZMS is the clear choice for

your network. ZMS manages the entire local loop network down to the device port level.

SCALABLE AND RELIABLE ARCHITECTURE

ZMS is based on the latest software standards and technologies. ZMS’s distributed client/

server architecture uses a proven, standards-based application platform providing scalability,

performance, and redundancy from the start. Unlike management systems based on propri-

etary platforms, ZMS is easy to integrate into existing service provider OSSs and third-party

products through a published CORBA interface.

The ZMS server (available in a UNIX operating system environment) provides a suite of man-

agement applications to support all functional areas of network management. NetHorizhon™ is

a Java-based client application (available for both Windows NT and UNIX operating systems)

that provides GUI access to all management functions. ZMS communicates with the network

via industry-standard protocols such as SNMP and FTP, using reliable mechanisms to ensure

timely transfers of management information. FCAPS data and relevant subscriber information

are stored in an industry-standard SQL relational database.

Scalability and high performance are built into ZMS. Multiple instances of a management

application can be geographically distributed and automatically load-balanced to handle both

client requests and OSS access. Redundancy is supported through automatic routing of client

requests to any available ZMS manager application, providing high system availability.

ZMS™

ZHONE MANAGEMENT SYSTEM

COMPLETE SUPPORT FOR ALL NETWORK MANAGEMENT FUNCTIONS

ZMS includes the following applications:

■ Fault Manager ■ OSS Gateway■ Configuration Manager ■ Database Manager■ Accounting Manager ■ Customer Network Management (CNM) Client■ Performance Manager ■ NetHorizhon Client■ Administration Manager

Fault Manager handles events from the network elements and correlates them into alarms.

It performs filtering, applies rules for various actions, and forwards alarms to external OSS

and third-party applications as needed.

Configuration Manager performs configuration changes for various objects in network

elements and provisions subscribers and end-to-end services within the Zhone environment.

It also handles element software downloads. The manager supports the use of templates,

which allow the operator to streamline configuration tasks.

Accounting Manager collects information on subscriber voice and data sessions for billing

and auditing purposes.

Performance Manager tracks network performance data in real time, collects historical

statistics, and monitors the status of various objects such as I/O cards, ports, trunks, and links.

This data allows service providers and subscribers to track trends and service levels.

Administration Manager controls access for NetHorizhon (ZMS Client), the CNM Client,

and OSS gateways. It does so through administration services that grant clients access to the

system based on user login and assigned privileges. A detailed audit log keeps track of all

operator actions for later analysis.

OSS Gateway provides a published CORBA interface for bi-directional transfer of all man-

agement information to the Zhone network. The interface provides a means to integrate

ZMS applications into service provider back-office systems and third-party applications.

Database Manager intelligently manages data for FCAPS functions in a relational database.

CNM Client provides subscribers web access so that they can manage their own service

based on assigned privileges.

NetHorizhon provides an intuitive graphical interface that operators use to navigate and

manipulate elements in the network. Maps and sub-maps represent Zhone domains. Network

operators can drill down for detailed views of back panel and front panel chassis, installed cards,

and I/O ports. On any element, operators can access configuration, status, and performance

information.

RAPID PROVISIONING

In today’s competitive landscape, service providers recognize that to attract new subscribers,

they need to be able to quickly roll out and provision new services. ZMS Configuration Man-

ager allows service providers to completely automate the provisioning of subscribers and

various network objects. Through the “File Manager”–like interface of NetHorizhon and

other tools (such as configuration and statistics templates and subscriber profiles), operators

can rapidly and accurately configure ports, trunks, links, and subscribers. Automated flow-

through provisioning can also be implemented directly from carrier OSS systems via the CORBA

IDL for complete integration.

End-to-end service provisioning within the Zhone network—via NetHorizhon or the CORBA

interface—enables rapid, one-step service provisioning with reduced carrier costs and increased

customer satisfaction. One-step provisioning eliminates tedious, error-prone, multi-step oper-

ations for providers. ZMS also allows subscribers to remotely control and provision their own

services and bandwidth.

The point-and-click NetHorizhon interface shows networkinventories and device configurations.

SUBSCRIBER AND SERVICE MONITORING

Service providers are constantly striving to provide networks that maintain the high service

levels that their subscribers demand. ZMS provides several tools that enable proactive track-

ing of potential bottlenecks and problems before they impact the network’s performance

and availability.

Traditional network operations involve managing devices, cards, ports, links, trunks, and

Customer Premise Equipment (CPE). ZMS offers selectable views that depict network operations

or subscriber-specific information, creating a whole new model for managing broadband

access networks. Operators can monitor subscriber services through these views, and when

service problems arise, they can retrieve any subscriber’s service path through the network,

pinpoint affected segments or elements, perform diagnostics, and quickly re-establish the

affected service.

ZMS Fault Manager performs advanced filtration and correlation to pinpoint service-affecting

areas. Network managers can use this information to differentiate intelligently between the

informational and service-affecting events that are generated throughout the network. In

ZMS™

ZHONE MANAGEMENT SYSTEM

conjunction with intelligence provided on Zhone network elements, ZMS allows for setup of

Threshold Crossing Alarms (TCA) to monitor service utilization, trunk usage, or link conges-

tion and notify operators of potential bottlenecks before they occur.

ZMS Performance Manager provides for real-time and historical collection of subscriber and

service data. By evaluating historical network parameters, network architects can efficiently

design and plan network growth. In addition, Performance Manager enables extended track-

ing of various metrics for Service Level Agreements (SLAs). Such information allows service

providers and their subscribers to confirm that service levels are being met. The collected

information can also be used for auditing and traffic planning purposes.

ZMS Accounting Manager retrieves usage-based subscriber session data on voice and data

traffic from Zhone network elements. Service providers can then use accounting information

to offer various billing services such as usage-based, time-of-day, and on-demand billing from

information collected in real time.

ZMS components are self-monitoring, allowing operators to upgrade components as required.

ZMS manager parameters (such as provisioning transactions/sec, traps, CPU usage, memory

usage, and disk space availability) provide for upgrade planning.

SECURE SUBSCRIBER ACCESS AND DATA SECURITY

Secure access and safe storage of subscriber data are major concerns for service providers.

ZMS Administration Manager allows the network administrator to configure various user

groups and assign a ZMS user to a particular group with privileges for defined tasks. Unique

subscriber and provider IDs are used to partition and store management information sent to

and from the network. These IDs allow for the smooth manipulation of data on a per-sub-

scriber basis, and they also facilitate network partitioning to support wholesaling models.

AUTOMATIC DEVICE DISCOVERY AND INVENTORY CONTROL

ZMS integrates an intelligent polling mechanism to monitor the status of nodes and connec-

tions between them. The BAN automatically discovers connected Zhone access devices and

CPE devices and notifies ZMS of any additions. The Object Tree application in NetHorizhon

presents all discovered information in a file manager-like structure for easy access to infor-

mation. ZMS tracks the inventory of equipment that has been discovered and reports its

statistics, including hardware version and loaded software revision on each device. Using the

reporting feature in NetHorizhon, users can print software and hardware inventory reports.

SIMPLIFIED OSS INTEGRATION

All Zhone network elements share the ZMS management environment; a common, open

set of Applications Programming Interfaces (APIs) and a standards-based CORBA interface.

By eliminating the multiple APIs and element management systems found in today’s access

networks, ZMS enables flow-through accounting and provisioning from back-office systems

to the subscriber premise. Since new network elements are quickly integrated into ZMS,

traffic and performance data on those elements automatically flow through to the OSS.

ZHONE MANAGEMENT CHANNEL

Typically, ZMS is connected to the BAN over Ethernet for access to all management functions.

Zhone Integrated Access Devices (IADs) are in turn connected to the BAN and are managed

in-band over SDSL/HDSL-2 connections. The BAN and all of its associated Zhone IADs are

managed as a single entity, simplifying management of even the largest networks, while

ensuring scalability and performance. IAD provisioning, software upgrades, and configuration

changes for new services are all accomplished via the Zhone Management Channel.

NMS VERSION INDEPENDENCE AND NON-SERVICE AFFECTING UPGRADES

While service providers generally want to take advantage of new features introduced in a

software release, they are often faced with large-scale upgrades that are planning-intensive

and require careful coordination among sites. ZMS addresses upgrade issues by supporting

version independence between client and server software and allowing for multiple versions

of a manager to coexist on the network. ZMS administrators can accomplish upgrades in

stages — one version of ZMS can be upgraded to a newer version, tested for satisfactory

performance, and then brought online so that other instances can be similarly upgraded.

REVENUE-GENERATING SERVICES

ZMS enables service providers to offer a full range of revenue-generating services to theirsubscribers.

CUSTOMER NETWORK MANAGEMENT (CNM) SERVICE

Subscriber self-administration is a key differentiator to service provider offerings. It facilitates

instant subscriber service changes and allows subscribers to view near real-time billing infor-

mation. By enabling CNM services, ZMS increases subscriber satisfaction, reduces services

support costs, and gives service providers the option to offer tiered CNM service packages

that generate additional revenues.

ACCOUNTING SERVICES

Information collected on voice and data services by the ZMS Accounting Manager and inte-

grated with billing systems makes it possible to offer new billing plans. Traditional flat-rate

billing offers little flexibility and doesn’t fit all subscribers. With ZMS, service providers can

bill on usage, time of day, or on demand.

SERVICE LEVEL MONITORING

Faced with increased competition, service providers are compelled to guarantee service levels

through contracts in order to attract new customers and reduce customer churn. ZMS is a

conduit that helps service providers monitor various Service Level Agreement (SLA) parameters

such as network latency, network availability, and throughput.

PARTITIONING AND WHOLESALING

Service providers who own the access infrastructure seek to wholesale broadband services to

other service providers, who can in turn offer them to individual business and residential

customers. ZMS, in conjunction with support provided in Zhone network devices, enables

smooth and secure partitioning of data, and also offers a partitioned view into the whole-

sale components of the network (through its GUI and other interfaces) for controlled access

to management functions.
