The Future's Bright for CarrierClass Optical Networking

The world of telecommunications is driven by changes in consumption

patterns. As illustrated in the following figure, telecommunications is moving

from voice PSTN to VoIP, from TDM leased lines to Ethernet VPNs, from

TDM-based 2G and 2.5G mobile networks to 3G data networks, and from

simple best-effort high-speed Internet access to advanced triple play networks

for small and medium businesses and home use. Today's challenge is to build

an infrastructure that maximizes bandwidth capacity while minimizing costs.

Operators must provide a carrier class standard of service with more bandwidth

at less cost per bit, and still get a satisfactory ROI.

Carrier Class Ethernet and MPLS

Ethernet service, the preeminent LAN technology, is now becoming thedominant service for the metro domain (WAN) as well. Consumers require

guaranteed service delivery of the appropriate quality, expecting operators to

provide differentiated services with comprehensive carrier class capabilities,

from access to core.

MPLS technologyis used to carry Ethernet services across the network metro

and core. MPLS as a transport layer for Ethernet services, rather than using

Ethernet as both transport and service layers, enhances Ethernet service,

enabling it to meet a complete carrier class standard, including:

Hard QoS, with guaranteed end-to-end (E2E) SLA for business, mobile,

and residential users that enables efficient Differentiated Services, allowingservice providers (SPs) to tailor the level of service and performance to the

requirements of their customers (real-time, mission-critical, best-effort,

etc.), as well as assuring the necessary network resources for Committed

Information Rate (CIR) and Extended Information Rate (EIR).

Reliability, a robust, resilient network that can provide nondisrupted traffic

across the path, including network protection of less than 50 msec

link/node Fast ReRoute (FRR) and meeting a five 9's standard of E2E

service availability.

XDM General Description Introduction


Scalabilityof both services and bandwidth, ranging from Mbps to

x10 Gbps with variable granularity, with hundreds of thousands of flows,

supporting complete controlled scalability for both the number of elementsand the number of services on the network.

End to End Service Managementthrough a single comprehensive

Network Management System (NMS) that provisions, monitors, and

controls all network layers, enabling management of multiple technology

layers (SDH, data, and optical) independently of the physical layer through

a user-friendly GUI. Supports fast service provisioning, low OPEX, and

mature OA&M capabilities through a complete Customer Network

Management (CNM) system.

TDM support, providing TDM legacy service integration through a native

MSPP platform for optimal NG-SDH functionality.

Security, with a secure environment that protects subscribers, servers, and

network devices, blocking malicious users, Denial of Service (DoS)

attacks, and use of provider network constraints, as well as complete traffic

segregation that ensures the highest level of security and privacy for even

the most sensitive data transmissions.

Flexible WDM/ROADM

Flexible Wavelength Division Multiplexing/Reconfigurable Optical

Add/Drop Multiplexing (WDM/ROADM)networksare becoming an

essential element of next-generation networks, chosen by operators who are

motivated by triple play delivery and business data connectivity demands.

These bandwidth demands require the capacity, resilience, and flexibility of

WDM/ROADM, structured as highly flexible all-range optical networks that

incorporate user-friendly line switching and E2E route selection.XDM's

field-proven multi-degree MEMS-WSS ROADM technology, together with

fully tunable lasers and innovative modular card designs, introduces true

flexibility to network design by providing any wavelength to any node

("any-to-any") connectivity in any ring or mesh topology, with no need to

predefine traffic demands and virtually unlimited capability to add or reroutewavelengths.

The unique, state-of-the-art architecture of the XDM enables it to

cost-effectively address metro, regional, and long-haul WDM requirements. A

single product line is used in all deployments, providing complete E2E

management over a multilayered WDM network with complete transparency.

The XDM also offers a rich set of Optical Transport Network (OTN) features

and advantages, including transponders with OTN framing and FEC,

combiners with OTH multiplexing and OTN PM, and OTN in-band

management in all transponders and combiners. The XDM extends the OTN

technology layer from the core down to the metro and access, enabling

operators to seamlessly manage their network wavelength services, end to end.

XDM next-generation optics also offers a full set of features aimed at

XDM: Today's Challenges andTomorrow's Goals

The key word in the industry is convergence, representing a single transport

layer that supports existing revenue-generating TDM through Next-Generation

SDH (NG-SDH) as well as carrier class Ethernet, combined with the power of

all-range flexible optics.

The XDM system architecture meets the needs of today's telecommunications

professionals for a MultiService Transport Platform (MSTP). It provides

flexible WDM optical service, market-leading NG-SDH capabilities, and

advanced carrier class Ethernet service delivery. The XDM is a single

converged platform that integrates the best technologies available for the

services currently being offered. Its unique architecture allows future

technology to be added to existing platforms, for smooth in-service migration.

The XDM platforms provide complete flexibility and scalability, with support

for any topology (multi-ring, mesh, star, and so on) and fully nonblocking

cross-connect capabilities. Everything is managed with E2E provisioning toolsand a layered network view that lets you manage all three layers (optics, SDH,

and Ethernet) through a unified, user-friendly graphic interface.

Figure 1-4: XDM's converged transmission technologies

The XDM platforms are the optimal choice for providing the range of services

expected by today's market. Traditional TDM services are no longer enough.

The market today demands VPNs, VoIP, IPTV, VoD, and HSI. Consumers are

looking for fast web browsing, interactive gaming, music, and more

personalized services.

Today's Incumbent Local Exchange Carriers (ILECs) must meet a dual demand

for NG-SDH as well as full triple play service. Mobile operators must meet a

demand for the 3G networks that are the wave of the future. Businesses must

respond to an ever-increasing range of required services, moving from the

original focused point-to-point (P2P) network into expanded

multipoint-to-multipoint (MP2MP) networks, with all their associatedcomplexities and benefits.

The XDM family of platforms is the natural choice for satisfying these market

demands. The XDM's unique architecture creates a seamless convergence of

transmission technologies. Multi-degree ROADM and all-range C/DWDM

capabilities are combined with carrier class Ethernet services, over a

sophisticated NG-SDH platform.

Optimized Network Convergence

The optimal network architecture for today's customer demands is a

convergence of Ethernet/MPLS, NG-SDH MSPP, and C/DWDM OTN

capabilities. This convergence enable SPs to exploit the benefits and robustness

of SDH together with the advantages of carrier class Ethernet through the use

of transport MPLS and the high capacity, resilience, and flexibility of

WDM/ROADM.

The converged metro aggregation network enables SPs to continue selling their

current TDM and HSI services while gradually adding the triple play services

of VoIP, IPTV, and VoD, as well as the ability to add any other Ethernet-based

services for business (VPLS), 3G Ethernet-based mobile aggregation,

wholesale services, and so on, in a single unified network.

The key benefits of a single converged network include:

Cost-optimized solutionwith incremental CAPEX/OPEX, gradually

adding next-generation service cards per customer demand, while allowing

continued sales of current TDM services.

Fast time-to-market(TTM) by adding any service, including new triple

play and wavelength services.

Revenue generationfrom new services together with any other

Ethernet-based services (LAN over the metro using VPLS, 3G mobile

services, wholesale bandwidth services, and so on).

E2E MPLSfrom access aggregation to IP/MPLS core router, assuring the

quality of service delivery with MPLS carrier class network capability.

Single unified managed networkwith the ability to provision any service,

including wavelength, TDM, and Ethernet-based services.

Risk minimizationthrough an evolving metro aggregation network, rather

than revolutionizing the network with the high risks involved.

power and benefits of each separate component under the smooth control of a

single management system, supporting full interoperability and providing E2Etop-down manageability of Ethernet service from access to core. The XDM

platform encompasses three functional layers:

Next-Generation SDH- expanding the limits of traditional TDM

leased-line services with a unique fully nonblocking matrix that provides

exceptional high-/low-order granularity capabilities. The XDM can be

configured to operate as either a single ADM/TM providing classic SDH

multiplexing functionality and operating at STM-1/4/16/64 line bitrates, or

as a multi-ADM/TM providing a more granular and scalable bandwidth at a

far lower cost than traditional TDM services, delivered over an existing

SDH network.

Carrier Class Ethernet Data Services- a comprehensive set of carrier

class capabilities that provide assured service delivery of the appropriate

quality for each Ethernet service, based on the capabilities of scalability,

Hard QoS, restoration, security, and simple management, integrated with

native support of NG-SDH.

The XDM provides a complete range of flexible optical capabilities,

servicing the other network layers as well as providing lambda services,combining SDH, data, and C/DWDM in a single platform that supports the

total wavelength provisioning flexibility of MEMS-WSS ROADM,

through 'any wavelength to any node' connectivity. The XDM is the only

truly converged MSPP/WDM equipment on the market today, with

field-proven state-of-the-art technology unmatched by any competitor.

Architecture (on page 3-1).

Next-Generation MEMS-WSSROADM

The massive growth in data, video, and packet voice traffic creates major

challenges to SPs worldwide. Expanding the transmission infrastructure to

accommodate new bandwidth requirements is essential. Nevertheless, wireline,

wireless, cable operators, and competitive carriers are faced with several

dilemmas, including:

Investing in new telecom infrastructure that will be both cost-optimized and

future-proof

Reducing operating and maintenance costs

Ensuring the appropriate QoS for each service type

Responding quickly to new and unexpected traffic demands

Implementing new technologies without risking network reliability

ECI Telecoms XDM product lines are specifically designed to address these

challenges. By offering a rich feature set based on innovative technologies anda highly field-proven platform, the XDM is the metro/regional WDM system of

choice for more and more SPs and carriers worldwide.

Multi-Degree ROADM-enabled Flexibility

Until recently, adding new channels and rerouting existing ones in a network

based on Mux/DeMux and fixed OADM technology was complicated,

labor-intensive, and often traffic-affecting. Even a minor adjustment often

required extensive network re-engineering. The XDM's MEMS-WSS ROADM

technology, fully tunable lasers, and modular card designs eliminate these

limitations by providing any wavelength to any node connectivity in any ring

or mesh topology. With the XDM, there is no need to predefine traffic demands

and virtually unlimited capability to add or reroute wavelengths.

Figure 1-8: Multi -degree development

7/22/2019 XDM_GD_ETSI_D00_7-7.1_en

25/290



One key advantage of using a 10-degree WSS ROADM is cost-effective

scalability with no traffic interruptions. Each degree corresponds to a 'colorless'

port that supports one or multiple wavelengths. For initial deployment, theROADM may serve as a typical two-degree OADM mode. As the network

grows, other ports are simply configured as multi-wavelength degrees for new

WDM rings or P2P connections.

Figure 1-9: Multi-degree scalability

When SPs consider ROADM deployment, they expect the following features:

Flexible wavelength assignment and reassignment, simplifying the

planning process and eliminating the need to predict future traffic flow

Ability to create complex optical topologies, such as:

Subtending CWDM and SDH ring closure Multi-ring DWDM hub

Mixed mesh and ring topologies

CAPEX savings:

Eliminating regeneration in both ring and hub nodes

Coarse and Dense WDM interworking eliminating back-to-back

systems

Reducing spare inventory with widely tunable 10 Gbps and 2.5 Gbps

transceivers

Reducing gain tilt in regional/long-haul networks, thereby extending

the distance between regeneration points

OPEX savings through fewer manual operations, such as:

'SDH-like' provisioning, making wavelength provisioning as simple and

quick as an STM-1

Remote provisioning and reconfiguration using software-tunable

components

Automatic power balancing and equalization

7/22/2019 XDM_GD_ETSI_D00_7-7.1_en

26/290



Implementing 10-degree Wavelength Selective Switch (WSS) technology, the

XDM ROADM supports all these benefits.

To enable flexible and cost-effective utilization of ROADM in both metro and

regional/long-haul networks, the XDM features an innovative

ROADM-optimized amplifier. This amplifier offers low noise, gain flatness,

and very high midstage access loss, accommodating a WSS ROADM and

dispersion compensation with no budget penalty. Plus it has a unique redundant

East/West architecture with no single point of failure. Functionally, it is

comparable to a two-stage Erbium-Doped Fiber Amplifier (EDFA) with

discrete amplifiers used in each direction for total redundancy.

True WDM and MSPP Convergence

The XDM is a true WDM/MSPP converged platform with built-in Ethernet

Layer 1, Ethernet Layer 2, SDH, and optical capabilities. As a simple example,

the XDM can add/drop any E1 to/from any STM-16/STM-64 wavelength on

the same shelf. With physical interfaces from 10 Gbps to electrical E1, the

XDM lowers both CAPEX and OPEX.

ECI Telecom pioneered the commercial introduction of convergence as an

innovative approach to optical networking in 2001. Though this concept is now

a trend with many optical network vendors, detailed market research shows that

no other field-proven platform can actually be configured as a pure

WDM/ROADM platform, SDH edge/core MSPP (with switching capacities of

30 Gbps, 60 Gbps, or 120 Gbps), or a converged ROADM and MSPPsynthesis.

Support of Ethernet-based services is already considered an integral part of any

transmission infrastructure. Carriers are counting on Ethernet as a vehicle that

will differentiate their offerings and attract more customers, while minimizing

the risks involved.

The essential aspects of a competitive optical Ethernet platform include carrier

class reliability, robust traffic protection, and diagnostics typically associated

with TDM services. Together, they provide vital Ethernet aggregation and

scaling capabilities for growing metro and regional networks. The XDM

feature set targets the evolution towards data-centric networks, and is designedto support Ethernet leased line (E-line), advanced Ethernet Virtual Private Line

(EVPL), and MPLS-based VPLS/VPWS services from access to core, featuring

a winning E2E approach.

7/22/2019 XDM_GD_ETSI_D00_7-7.1_en

27/290



As Ethernet customers and portions of the network start to migrate towards

higher capacity, the underlying network infrastructure must expand as well.

Some of the Ethernet services will thus be provided directly over an opticalinfrastructure.The XDM provides the ideal interconnectivity for these

services, whether SDH-or WDM/OTN-based (see "The Promise of OTN" on

page 1-17).

Maximized Capacity and Range

The unique architecture of the XDM enables it to cost-effectively address

metro, regional, and long-haul WDM requirements. The XDM provides

complete E2E management over a multilayered WDM network with complete

service transparency.

Two of the key aspects of a C/DWDM system are its capacity and range. The

XDM is asingle high-capacity all-range WDM solutionfor short, medium,

and long-haul routes. It is optimized for any capacity (8, 16, 32, 40, or

80 channels of 2.5 Gbps, 10 Gbps, or 40 Gbps each), and for any range (80 km

to 2,000 km/50 miles to 1250 miles). For example:

Up to 80 km/50 miles (16 x 2.5 Gbps) with OTU1 Forward Error

Correction (FEC) and no amplification

Up to 300 km/190 miles (80 x 10 Gbps) single span, with OTU2 Enhanced

FEC (EFEC), EDF, and Raman amplifiers

Up to 900 km/550 miles (80 x 10 Gbps) with OTU2 EFEC and single-stage

EDFAs

Up to 2,000 km/1250 miles (80 x 10 Gbps) with OTU2 EFEC, RZ

modulation, and dual-stage variable gain EDFAs

The Promise of OTN

The ITU-T defined a set of standards for OTNs, primarily under rec. G.709. An

OTN is defined through a set of characteristics that includes wavelength

framing, FEC, digital multiplexing of 2.5 Gbps to 10 Gbps and to 40 Gbps,

multi-domain performance monitoring (PM), optical protection, in-band

management, alarm correlation, and more. OTN provides many benefits to

carriers, including:

Universal management layer for wavelengths, regardless of the

underlying services offered (IP, Ethernet, SDH, etc.), simplifying operation

Extended reach via forward error correction and enhanced FEC (EFEC)

Timing transparencyfor timing-sensitive applications, such as SDHtransport

High capacity in-band management, simplifying and reducing the cost of

metro WDM networks

The XDM offers a rich set of OTN features and advantages, including:

OTN framing and FEC used in all XDM transponders for 2.5 Gbps,

10 Gbps, and 40 Gbps, including a class-leading transponder for

10 GbE LAN to OTN 10 Gbps

XDM combiners/muxponders that implement OTH multiplexing for timing

transparency and OTN PM

OTN in-band management (GCC bytes) supported in all XDM

transponders and combiners

Furthermore, while OTN development was originally focused on the core, the

XDM extends this technology layer down to the metro and access, enabling

carriers to seamlessly manage their network wavelength services, end to end.

Figure 1-12: OTN as a universal t ransport layer, access to core

Ease of Installation and OperationOne of the key benefits of XDM next-generation optics is a full set of features

aimed at simplifying planning, installation, operation, and maintenance of

WDM/ROADM networks (previously considered fairly complex). XDM

provides all the convenience of modular automated optics technology,

including:

Comprehensive planning tool for bandwidth optimization, optical link

design optimization and verification, shelf layout, and more

Enhanced Automatic Power Control (EAPC)continuously ensuring

network resiliency, automatically adjusting to changes in optical powerinduced by variations in span loss and/or in the number of active channels,

and providing comprehensive information on network status and history

Carrier Class MPLS/Ethernet

ServiceIn today's telecommunications industry, SPs face a decline in available

resources due to multimedia-based services and intranet applications requiring

large amounts of bandwidth. Carriers and SPs therefore require a highly

scalable broadband and metro aggregation infrastructure to deliver increasing

amounts of data traffic to their customers seamlessly and transparently.

SDH and PDH have long been dominant technologies in WAN and PSTN

environments, primarily in networks that were designed to carry voice. In light

of the increasing demand for additional reliable capacity, SDH was deployed

more and more in metropolitan and core networks. Shortly afterwards, thesenetworks had to cope with a huge explosion of Ethernet service data traffic.

Networking equipment is increasingly using Ethernet (10BaseT, FE, and GbE)

as the connection technology of choice for data communications. Ethernet

services offer a simpler, more cost-effective, and more suitable solution to meet

customer needs for transparent LAN-to-LAN connectivity.

The capacity needed to meet these new demands is outpacing SDH's ability to

cost-effectively scale up to higher speeds. Metro WDM has become a common

solution for dramatically increasing bandwidth on existing fiber infrastructure.

What is needed, therefore, is an infrastructure that combines the most important

features of SDH (guaranteed latency, reliability, and protection), and thecapacity of WDM, with the simplicity, ubiquity, scalability, and low cost of

Ethernet. Networks based on the XDM provide this infrastructure.

Ethernet Aggregation

The XDM provides a carrier class transmission solution for emerging

Ethernet-based applications, such as:

Triple play

Business connectivity (enterprise and medium/small offices)

3G (Rel-5) Ethernet-based mobile aggregation

DSLAM transport and aggregation

7/22/2019 XDM_GD_ETSI_D00_7-7.1_en

The XDM's wide range of Ethernet cards, including Layer 1 (DIOB/DIOM),

Layer 2 (EIS/MB), and MPLS (MCS/M), supports a full set of Ethernet

services with E2E QoS.

Figure 1-13: Variety of Ethernet services

7/22/2019 XDM_GD_ETSI_D00_7-7.1_en

33/290



The XDM is the optimal choice for providing data-centric services, including:

Ethernet Line (E-Line)for P2P connectivity, used to create Ethernet

private line services, Ethernet-based Internet access services, and P2P

Ethernet VPNs. These include:

Ethernet Private Line (EPL)- P2P Ethernet connection that uses

dedicated bandwidth, providing fully managed highly transparent

transport service for Ethernet. EPL provides an extremely reliable and

secure service, as would be expected from a private line.

Ethernet Virtual Private Line (EVPL)- P2P connectivity over shared

bandwidth. Service can be multiplexed at the User to Network Interface

(UNI) level. EVPL is used for hub and spoke architectures in which

multiple remote offices require access to a single headquarters or

multiple customers require access to an ISP's POP. Virtual Private Wire Service (VPWS)- P2P connectivity over MPLS

pseudo-wire (PW) shares the same tunnel on the same locations, so

benefiting from MPLS E2E Hard QoS and carrier class capabilities.

Figure 1-14: E-Line service

Ethernet LAN (E-LAN)for MP2MP (any-to-any) connectivity, designed

for multipoint Ethernet VPNs and native Ethernet Transparent LAN

Services (TLS). These include:

Ethernet Private LAN (EPLAN)- multipoint connectivity over

dedicated bandwidth, where each subscriber site is connected to

multiple sites using dedicated resources (so different customers'Ethernet frames are not multiplexed together).

Ethernet Virtual Private LAN (EVPLAN)- multipoint connectivity

over shared bandwidth, where each subscriber site is connected to

multiple sites using shared resources. This is a very cost-effective

service, as it can leverage shared transmission bandwidth in the

network.

7/22/2019 XDM_GD_ETSI_D00_7-7.1_en

34/290



Virtual Private LAN Service (VPLS)- multipoint connectivity over

MPLS PW shares the same tunnel. The VPLS enables delivery of any

to any connectivity that expands business LAN across the wide areanetwork. VPLS enables SPs to expand their L2VPN services offering to

enterprise customers. VPLS provides the operational cost benefits of

Ethernet with E2E QoS of MPLS.

Figure 1-15: E-LAN service

E-Tree (Rooted-Multipoint)for P2MP Multicast Tree connectivity,

designed for BTV/IPTV services. These include:

Ethernet Private Tree (EP-Tree)- in its simplest form, an E-Tree

service type provides a single root for multiple leaf UNIs. Each leaf

UNI only exchanges data with the root UNI. This service is useful and

enables very efficient bandwidth use for Broadcast TV (or IPTV)

applications, such as multicast/broadcast packet video. With this

approach, different copies of the packet need to be sent only to roots

that are not sharing the same branch of the tree.

Ethernet Virtual Private Tree (EVP-Tree)- an EVP-Tree is an

E-Tree service that provides rooted-multipoint connectivity across a

shared infrastructure supporting statistical multiplexing and

over-subscription.

MPLS Routed-P2MP Multicast Tree (Drop & Continue)- an MPLS

drop-and-continue multicast tree on a shared P2MP multicast tree

tunnel supports multiple DTV/IPTV services as part of a full triple play

solution.

The XDM Ethernet services implementation is ideal for customers that want to

add bandwidth on demand based on the expected increase in their data traffic.

This enables a true pay-as-you-grow infrastructure, allowing them to acquirecapacity only when they need it. The platform's carrier class Ethernet

networking services that are provided directly to customers in wide-area SDH

networks guarantee:

Point-to-point, multipoint-to-multipoint, and multicast connectivity

Assured Hard QoS through MPLS traffic engineering (TE) and SDH

network features

Transparency of protocols and bitrates to end user data packets

MPLS and SDH reliability and security levels

< 50 msec link and node protection through MPLS

Extended Ethernet scalability of VLANs through MPLS

Simple point-and-click Ethernet service creation and management

Comprehensive SLA metrics

Extreme cost-effectiveness

XDM provides these data-centric services over fiber with broadband flexibility

and capacity. Services are easy to provision and adjust, offering customers

bandwidth scalability optimized for their unique requirements.

Bandwidth is allocated to Ethernet services in VC-12/3/4 increments. The

service rate adapts to end-user needs, allowing carriers to tailor pricing to a

finer granularity of data rates.

The XDM features three independent cards for Ethernet in mixed SDH and

Ethernet networks: the Data I/O cards (DIOB and DIOM), the Ethernet

Interface and Switching Module (EIS and EISMB), and the MPLS Carrier

Class Switch (MCSM/MCS5/MCS10). These cards are described in detail in

MPLS and Ethernet Data Solution (on page 5-1).

Next-Generation SDH

SDH has evolved from a simple voice-centric technology to a next-generation

solution capable of efficiently delivering Ethernet services together with the

revenue-generating TDM service demanded by today's metro applications. The

XDM offers a migration path to the future, both by expanding today's SDH

networks to DWDM terabit capacities, and by offering data-oriented services

such as Ethernet, IP, and storage (SAN), over existing legacy networks.

Moreover, XDM networks provide a better utilization of network resources

through the migration to fully protected mesh configurations with variable

service grades and sublambda grooming of DWDM channels. This results in an

extremely cost-effective solution.

The NG-SDH architecture of the XDM enables the following advantages:

Support of any network topology, including mesh, ring, multi-ring, star,

and linear topologies

Network control through a single network management system, the

LightSoft Network Manager

Unique, full low-order/high-order nonblocking cross-connect

technology, enabling complete interconnectivity and switching capabilities

between STM-n interfaces and wavelengths

Smooth migration path from 30G through 60G to 120G capacity within

the existing shelf

Concatenated payloads for various service rates, encompassing both

contiguous and virtual concatenation

Delivering Ethernet services over SDH through standard means:

GFP

VCAT

LCAS

Classic metro networks consist of multiple rings with a few stacked rings

sharing the same physical paths. In these traditional networks, each ring uses itsown set of ADMs. Connectivity between rings is limited and expensive,

requiring the use of large digital cross connects (DXCs).

When functioning as a multi-ADM, the XDM achieves multiple ring closure

with full inter-ring connectivity. The XDM's full low- and high-order

connectivity eliminates the network bottlenecks typical of metro networks. The

XDM also saves equipment costs by substantially reducing the number of NEs

required. It simplifies the network, eases operation, increases reliability, and

reduces operating expenses.

7/22/2019 XDM_GD_ETSI_D00_7-7.1_en

37/290



The XDM replaces an array of terminal multiplexers, terminating the SDH line

and delivering lower-rate services to end users. The platforms integrated ADM

and cross-connect functionality allows the network to be built in topologiesother than rings, such as cost-effective mesh, while providing connectivity and

services from the same NE.

Figure 1-16: XDM in multi-ring closure mode

Introducing ASON in the XDMEthernet-based oriented services are increasingly becoming the preferred

choice for transmission network traffic. Traffic patterns and protection

requirements are shifting to shared protection schemes relying on efficient

mesh protection methods to make better use of bandwidth resources.

ECIs XDM family supports this evolution with an innovative networking

framework that minimizes operating costs while maximizing revenues. The

XDMs Automatically Switched Optical Network (ASON) architecture and

Generalized Multiprotocol Label Switching (GMPLS) protocols help carriers

reduce CAPEX and OPEX by enabling efficient optical network planning and

operation. The XDM platforms facilitate revenue-generating services, such as

Gigabit Ethernet, optical virtual private networks (O-VPN), bandwidth ondemand (BoD), and differentiated Class of Service (CoS). For example, as a

BoD application, UNI for SDH and DWDM enables client equipment to

request the creation, tear down, and modification of trails. The XDM

networking tools are based on emerging standards from ITU, IETF, and OIF, as

well as advanced distributed control plane architectures.

Key components of the XDM management and control suite include:

Automatic topology discovery

Resource dissemination

Point-and-click connection provisioning

Automatic user-initiated setup

E2E PM across an SDH circuit

Network-wide E2E path protection and restoration

The XDM also provides a variety of bandwidth-efficient protection and

restoration schemes, while supporting ring, mesh, and P2P network topologies.

Protection modes include linear MSP, fast mesh restoration, SNCP, andMS-SPRing.

Service providers know that OPEX is dramatically improved through

simplified service provisioning and network maintenance. XDMs automatic

discovery capabilities, including plug&play neighbors and resource

introduction as well as status and topology identification, help carriers reduce

OPEX significantly. The XDMs distributed dynamic routing capability allows

for rapid cost-effective addition of new nodes and additional bandwidth,

without the extensive offline operations required today.

With XDM, the network is the database.

ILECs

Today, Incumbent Local Exchange Carriers (ILECs) are being forced to

re-evaluate their business plan. Cellular and cable operators are now expanding

their own service offering by moving into the traditional voice telephony

service arena. As a result of the intense competition, ILEC profitability is

decreasing and they are now searching for new ways to increase their revenues

(for example, by moving into providing media services to both private and

business customers), while reducing expenses.

One of the trends in the consumer market is the triple play, where ILECs offer

customers not only traditional voice but also broadband Internet access and

video services. Many ILECs are even looking into expanding their service

offering into the newer realm of quadruple play, adding mobility to the tripleplay mix. In the future, ILECs hope to position themselves as the SPs of choice

for telephone, television, high-speed Internet, and wireless services. To

accomplish this goal, they will be looking for suppliers of network equipment

that responds to their demands for secure, reliable, flexible, and cost-effective

service.
