The PTN market opportunityTDM services and SDH technologies were originally designed to deliver voice.Voice is a mandatory service with specific requirements, but its capacity in theentire network is very small - less than 10 percent in most cases.

Most of TDM services today are leased-lined that enterprises consume toconnect their remote offices. TDM is considered as reliable and a secureconnection, and therefore it was widely adopted as a VPN enabler. 155Mbpsthat is achievable with an STM-1 connection is a popular example.

The introduction of carrier-grade switches and routers brought an alternativewith a much higher capacity and lower cost. The result was acceptance ofEthernet services for enterprise VPN and residential triple-play service.

A closer look at the actual business that is deriving from the TDM leased-linesreflects this trend - most of the TDM services are actually Ethernet-over-SDHservices that are still producing good margins to the telecom serviceproviders.

But the increased competition (a practical alternative for an enterprise toreplace its STM-1 service with Gigabit Ethernet service) with the exponentialgrowth of packet services is changing the overall picture.A long term view on the traffic that networks will need to deliver is clear -Ethernet is the growth engine, and Ethernet will capture most of the traffic inthe next-generation networks.

Industry analysts describe this dramatic shift from legacy TDM circuits topacket based networks in their market segmentation and forecasts.

SDH gear that was heavily deployed as networking transport layer isapproaching its end-of-life / end-of-service and is not capable of delivering

large capacity of Ethernet services over its circuits. As a result, SDH market isdeclining from ~ $4 billion market today to $2 billion market at 2013.

New investments are allocated in packet based networking solutions. Thisincludes the emerging Packet-Optical Transport System (P-OTS) and CarrierEthernet Switches and Routers (CESR) markets.

The CESR market today captures ~ $2 billion and is expected to reach $3billion at 2014, and the P-OTS market with its hybrid WDM + SDH + MPLSvision is starting to capture significant role as next-generation MSPP. Fromearly adoption today, this market is expected to grow aggressively in the near

future.

The PTN market opportunity, both within the CESR and P-OTS markets is toenable unified transport layer for mobile backhaul, SDH migration, and CarrierEthernet applications.

Orckit-Corrigent PTN solution for mobile networksOne of the most important growth engines for mobile operators is their abilityto offer any type of content. Massive delivery of internet and TV content isimpacting the mobile backhauling infrastructure that was originally built tohandle voice traffic. The roadmap to fulfill the clear needs and vision includes

technical challenges such as how to deliver significantly more data whilepreserving the synchronous nature of the network and how to perform phasedmigration from a TDM network to a packet-based network. MPLS and MPLS-TP technologies that are adopted by fixed-line service providers are offering afield-proven and cost effective basis for PTN based mobile backhauling.

A typical PTN architecture for mobile backhauling includes the accessnetwork where Ethernet and PDH devices are located below the antennasand receives all the voice and data services. In the access network, a CellSite Gateway (CSG) switch is encapsulating E1 and Ethernet to packets.From the CSG, synchronization and QoS is assured from the PTN.PTN aggregation layer is typically based on MPLS-TP technology andincludes Hub Site Gateway (HSG) switch and transport capabilities toeffectively deliver all the traffic to centralized controllers.At the core, Aggregation Site gateway (ASG) is handling all incoming trafficand sends Ethernet/SDH/ATM services to their appropriate controller.Note that the Ethernet traffic doesnt need the gateway functionality and issimply being carried over MPLS PW towards the controller at the backbone.

Orckit-Corrigent PTN solution for SDH and PDH migrationIt is common knowledge that telecommunication service providers worldwidehave transport networks that were originally designed to deliver TDMservices. Yet due to the exponential growth in data services we haveexperienced over the past few years, next-generation transport is facing

scalability and cost challenges and therefore embedding packet capabilities.

In order for telecom service providers to preserve their TDM services, know-how and investment, it has become increasingly obvious that some kind of amigration plan is needed. One such approach would be to emulate TDM inpacket-based switches and routers. In line, another option would be to embedpacket technologies such as Ethernet and MPLS / MPLS-TP into thetraditional transport systems.

A typical TDM networking infrastructure is based on SDH rings. Accessnetwork connect the subscribers to PDH service such as E1 and E3. Ethernetservices are delivered over SDH. Networking upgrade is starting withadditional linecards on the existing network elements and even additionalrings. Since packet based services are growing exponentially, upgrade isneeded to support packet services over TDM rings. The PTN migrationsolution offers a natural, scalable and cost effective alternative instead ofadding Ethernet service on SDH infrastructure, add Ethernet services onEthernet infrastructure and carry all the legacy services on the new andunified networking layer.

Orckit-Corrigent PTN solution for SDH and PDH migration uses the standardand interoperable PTN switches that were originally built for the delivery oflarge capacity packet services, and adds packet synchronization and circuitemulation technologies to enable any SDH and PDH TDM services. Thepacketized TDM services are equivalent in their quality to those being

provided by the traditional SDH networks. This approach provides theopportunity for smooth migration from a legacy TDM network to a packetnetwork, since the TDM linecards can be added and removed at any time.

Orckit-Corrigent PTN is a packet-based, future-proof solution both for legacyand next-generation services. Unlike MSPP and P-OTS alternatives, it is notan intermediate solution that optimizes specific mix of TDM and Ethernet.

With Orckit-Corrigent PTN solution, the smooth SDH migration is done in thefollowing few steps

1. Step #1: Building MPLS / MPLS-TP aggregation network and

offloading high capacity TDM traffic from the SDH backbone2. Step #2: Adding a multi-service access network to carry any service

from the access network3. Step #3: Phasing out the SDH backbone while preserving the

investment, subscribers and services in the TDM access4. Step #4: Completing the phased migration with a standard and

interoperable PTN

This process has few valuable benefits to the telco service provider: startingwith PTN at the metro and offloading SDH high capacity services gives theopportunity to experience the PTN layer without affecting the existingsubscribers and services. Adding the Ethernet access network whilepreserving the legacy TDM access, is saving Capex and simplifies thesolution. At a cretin point, where SDH backbone Opex is higher than itsrunning service and unified packet layer is in place the complete migrationtowards unified PTN is done naturally.

Important note about SDH migration using PTN is that TDM service isencapsulated to a packet service, running on a regular MPLS PW. When thisservice is removed any other packet service it taking his place andresources.

In P-OTS implementation, a hybrid TDM + packet hardware and software isbeing implemented and therefore each service has dedicated processing (thisis done both in universal switching fabric and dual switching fabrics).

PTN adds TDM services over MPLS PW, while P-OTS has dedicated hardware and softwarefor TDM and Packet

P-OTS is the technology of choice for multiservice national backbones whichrequire integration between high capacity ROADM technology, packettransport and TDM transport in a single box. When attempting to use thesame technology for metro applications, however, its major disadvantagesbecome clear. The multiservice switching technology forces the P-OTSdevices to act as two separate products in one cage with TDM traffic handledcompletely separate from the packet transport. Converging the twotechnologies by means of Ethernet over SDH simply turns the P-OTS into aregular MSPP.

PTN solution, on the other hand, is designed and optimized for metroapplications. Its unified packet switching keeps the system cost at a very lowprice point and the Opex is kept low with a single transport approach.

Orckit-Corrigent PTN solution for Carrier Ethernet enterpriseand residential applicationsEnterprises consume Ethernet connectivity services from telecommunicationservice providers and demand strict service level agreement (SLA). Thismeans that the required networking infrastructure needs to provide advanced

quality of service (QoS), availability, and reliability mechanisms.

Metro Ethernet Forum (MEF) has defined the de-facto services terminologyfor Ethernet-based VPN services. The most popular terms include: EthernetLine (E-Line) service for point-to-point connections, Ethernet Tree (E-Tree)services for point-to-multipoint/hub-and-spoke connections, and EthernetLocal Area Network (E-LAN) service for multipoint-to-multipoint connections.

While small enterprises generally consume IP/Layer 3 VPN services, mediumand large enterprises prefer Ethernet/Layer 2 VPN services due to simplicity,cost, and scale advantages. Therefore, connection-oriented Ethernet andMPLS / MPLS-TP technologies are the natural choice at metro area networks.

In addition to enterprise VPN services, residential triple-play is a very popularterm that includes voice (VoIP), video (IPTV/VoD), and data (high speedinternet) services to a large number of household subscribers.

A typical metro area network includes one or more levels of aggregation andtherefore a high granularity of Ethernet interfaces and switching capacity isessential. In addition, metro area network needs carrier-grade switches androuters with connection-oriented technologies. MPLS is the dominant

technology in Packet Transport Networks and since the technology isstandard and interoperable, multivendor approach is feasible in ring or meshnetwork topologies.
