6 1. INTRODUCTION The demands for mobile and fixed broadband services are justifying the technology, topology and business model innovations being implemented today. Moving into unified IP packet networks and end-to-end network management allow you to offer premium services including conventional voice service over packet as well as sharing or reselling your backhaul bandwidth. However, the right backhaul evolution strategy very much depends on the differing motivations of each operator such as preferences in OPEX, CAPEX, flexibility, control and scale. ipasolink is NEC s most advanced and comprehensive optical and radio converged transport product family, providing solution for backhaul optimisation and transformation to help you achieve your business objectives such as cost efficient integration of both TDM and carrier-class Ethernet network and versatile and smooth migration from TDM to IP next generation network. The ipasolink family covers from the last mile to the aggregation metro backhaul and is composed of ipasolink 200, 400 and ipasolink 200 is a basic configuration for nodal application in the wireless ipasolink family and providing up to 440 Mbps with flexible combination of native TDM and/or native Ethernet transmission and advanced adaptive modulation scheme operating in 6, 7, 8, 10, 11, 13, 15, 18, 23, 26, 28, 32 or 38 GHz bands. The ipasolink 200 consists of antenna, outdoor unit (ODU) and indoor unit (IDU) like as PASOLINK series and accedes to very high performance and ultra high reliability gained through NEC s rigid TQC activities and vast experience in wired and wireless communication fields. IDU ODU Figure 1.1 ipasolink 200 A single indoor unit (IDU) of ipasolink 200 can accommodate up to two (2) independent transmission channels. This allows you to configure back-to-back 1+0, same direction 1+1 twin path, hot standby, diversity or, thanks to NEC s latest cross polarization interference canceling techniques, double the transmission capacity up to 880 Mbps utilizing both polarizations within the same costly and limited licensed radio frequency channel. All this is achieved without any header suppression or elimination of packet data. This double capacity feature facilitates more room for backbone services such as 3GPP over Ethernet network or TDM services during transition from TDM to IP network. 2. ADVANTAGES The ipasolink family is designed around two (2) basic principles to provide the all-ip wired and wireless intelligent converged network for customer s benefits; MTD - ipasolink 200.doc - 1 -

7 Providing more transport flexibility & reliability: ipasolink family includes microwave and fiber transmission, switching and aggregation functions, is supporting from E1/T1 to STM-16 or carrier-class Fast Ethernet to 10G Ethernet for transmission of TDM and packet data, and designed to deliver high throughput and low latencies while avoiding reliability problems of TDM-over-packet network, QoS, route protection on different TDM and Ethernet backhaul topologies. Technologies such as double capacity radio through XPIC with hitless adaptive modulation, independent cross-connection and MPLS switching capability bring performance, power and flexibility to the hybrid network toward next generation IP/mobile networks. Operation continuity & upgradability Based on NEC s commitments of IP migration strategy, enhancement of end-to-end TDM and packet backhaul management and northbound interface capabilities - for network optimization, traffic engineering, QoS and route protection management - are included into ipasolink portfolio. Together with these enhancement, "Pay as you need" remote upgrade concept is also applied to ipasolink family platforms. The modular construction with universal card slots and integrated management software ensures operation continuity and upgradability from each hop or node. Customer benefit NEC s backhaul engineering foresights enable the adoption of IP network in cost-effective manner. The ipasolink broad scope of backhaul media and convergence technologies such as MPLS allow any service (fixed, mobile or wireless broadband) to happily co-exist in one physical backhaul. This backhaul unification by ipasolink platforms reduces cost and complexity where operators require multi-service backhauls or complete service transparency enabling to offer backhaul capacity to other providers to earn further revenue from your backhaul. Moreover, you can re-design your backhaul in terms of topology, capacity and intelligence while reusing existing infrastructure. Specifically, in the mobile backhaul, the ipasolink family ensures you can scale from 2G/3G to higher broadband access speeds without a proportional increase in cost. MTD - ipasolink 200.doc - 2 -

11 Adaptive modulation radio (AMR) AMR is a technology to improve robustness mainly in the packet transmission environment by utilizing thermal threshold difference between modulation hierarchies, such as QPSK 256 QAM etc. For instance, intensive rain causing receiving level attenuation at high frequency bands, AMR keeps the link availability by automatically and error-free selection of the lower threshold modulation. For example, QPSK threshold is 6 db lower than 16 QAM but transmission capacity becomes half (See Figure 2). In the IP packet transmission, i.e., no hierarchy transmission case, link connectivity in other word, robustness might be more important factor even though transmission capacity is significantly reduced. However, in the hybrid transmission, it is recommended to keep the same transmission capacity for TDM transmissions including PWE or CESoP even at degraded receiving conditions. Prioritization between TDM and Ethernet packets or prioritization between Ethernet ports or VPN-base is the quite important matter to maintain the quality of the highest priority service. Based on NEC's vast experience on microwave to millimeter wave propagation, the most realistic reliable AMR functionality from the device level was developed and equipped in ipasolink family platforms retaining the QoS parameter setting capability on AMR operation. Table 3.1 shows the AMR range for channel spacing and modulation scheme.

14 4. APPLICATIONS The MW radio products belonging to the ipasolink family are modular backhaul platforms that integrate a comprehensive set of packet switching, TDM cross-connect switching and microwave/optical features covering all applications - from the tail to the metro backhaul through aggregation node Applications for mobile backhaul Traffic of mobile circuit switched services (CS) is maturing and CS Voice ARPU is approaching the saturating point. In contrast, Packet data traffic is gradually increasing. Although current data traffic is not so large due to high cost to the users and limited service contents, revenue increase can be expected by expanding the IP services especially for corporate sector services (M2M, B2B/C) such as VPN and cloud computing services to sensors, smart phones and thin-client terminals. However; - Amount of required bits for data service is much larger than those for voice and significant bit-cost reduction is absolutely required. - Transmission capacity per cell will increase significantly. This has to be improved while considering that the available existing spectrum is limited and new spectrum would be higher in frequency and cost. The following might be a mandatory requirement to survive this highly competitive field: - Spectrum efficiency improvement including adoption of multiple Mini/Micro/Femto-cells in mobile RAN and; - Adoption of low-cost packet data aggregation (statistical multiplex) and autonomous decentralization such as off loading, metro mesh WDM and MPLS VPN etc in Ethernet backhaul. With all these considered, it is clear that migration to all-packet mobile networks is the way forward. However, current majority earnings are from 2G/3G CS voice service which can not be replaced to LTE in a short period of time. All-IP migration strategy of existing 3GPP Release-99 operators might be different from other mobile operators due to difference of mobile architectures adopted. Based on these mobile trends and applied mobile architectures, the ipasolink for mobile backhaul solution is shown in Figure 4.1. The ipasolink family supports Dual Native (native TDM and native Ethernet) operation. It is possible to provide TDM and Ethernet Hybrid transmission or IP transmission within the same equipment, without an external box. Therefore ipasolink can provide flexible and optimized migration scenario according to network situation and customer s evolution. MTD - ipasolink 200.doc - 9 -

15 MTD-PL-050/ ipasolink 200 Figure 4.1 ipasolink for mobile backhaul The ipasolink family supports the all of the following transmission architecture: - Native TDM TDM based network is the bandwidth-guaranteed and synchronous network. It is free from time and synchronization issues. However, TDM network can not manage the growth of data traffic efficiently. - Native IP Unlike Native TDM network, IP based network can accommodate the growth of data traffic efficiently. In addition, wiring work can be reduced dramatically as a result of shared connections. However, IP-based network, due to its asynchronous and on-demand nature, does not guarantee synchronous delivery of data. Therefore, synchronization issue due to fluctuation of delay, latency or jitter must be carefully considered in transmission of mobile service. - Dual Native (Native TDM and Native IP) Both packet switching and TDM cross connect are supported natively, which enables flexible transport per traffic type on a single platform. Without incurring additional latency, delay/jitter sensitive traffic and clock such as 3GPP Release-99 traffic is transmitted on TDM network directly, and IP based traffic such as LTE traffic is transmitted on IP network directly without conversion. Moderate packet data growth may be efficiently aggregated by statistical multiplexing while keeping the quality of delay/jitter sensitive TDM services. - TDM splitting (with PWE) and Traffic Offload / Concentration MTD - ipasolink 200.doc

16 MTD-PL-050/ ipasolink 200 TDM splitting enables a port of legacy network traffic, such as HSPA data, to be dispensed onto IP network with Pseudo-Wire Emulation (PWE), keeping only critical and timing-sensitive data on TDM network. With this functionality, it is possible to streamline legacy network while increasing IP network usage. PWE should be applied for transmission of jitter and latency relaxed services or where clock synchronization within mobile RAN has been established by adoption of other synchronization measures. Traffic offload allows the operator to unload their IP traffic, including emulated legacy traffic, into more cost effective IP network. The benefit of traffic offloading is twofold: > Differentiation of services to customers > Reduction of OPEX by converging voice and data traffic In contrast to offload, concentration creates an opportunity for wholesale operators and carriers to maximize the utilization of their networks by converging services and traffic from various customers Mobile network (2G/3G/LTE) Mobile services require very accurate clock, such as 0.05ppm for 3GPP macro base station, for Location Service (LCS), handover and other pseudo synchronization among mobile platforms. Usually clock is distributed from BSC/RNC in 3GPP Release-99 GSM / UTRAN (2G/3G) systems. It is very hard to transmit this very accurate clock to entire BTS / e-nodeb through ordinary IP network. IP migration process should be carefully considered and planed to minimize the risk to existing services and additionally required CAPEX and OPEX for 2G/3G services being turned off in future. Therefore, adoption of Dual Native backhaul would be risk-free, the most flexible and cost effective migration method towards all-ip network. Long haul application for mobile network ipasolink 200 has 2-way nodal capability. Relay connection can be provided by one ipasolink 200 IDU. Figure 4.2 Long-haul mobile network Where accumulated end-to-end jitter and latency becomes an issue of synchronization or throughput due to multi-tandem hops in the long-haul packet application, keep the TDM services as is. Dual native transmission is the most suitable solution in this application. The ipasolink 200 shall be used simply as back-to-back connected repeater except on the end terminals. ipasolink is applicable to a wide range of network applications, and can be seamlessly integrated in networks with diverse customer requirements.

PNMSj provides a single access point from where to monitor and control an entire network continuously. The PNMSj software contains overview maps of the network and its sub-networks to provide an easy, single glance, overview of an entire network. MTD - ipasolink 200.doc

28 PASOLINK Management function The PASOLINK Management function is mounted on the Control module for the PASOLINK IDU. It takes care of the communication between the PASOLINK terminal and Network Management system. In addition, it collects event and performance data from the PASOLINK equipment and stores it. They can communicate with each other via one of the service channels to enable remote access to any PASOLINK in a network from a single access point. Figure 6.1 shows the concept of NMS for PASOLINK. Figure 6.1 NMS Concept MTD - ipasolink 200.doc

29 6.2. Features Any platform Free from OS limitations, PNMSj runs on either Windows XP or Windows Vista or UNIX. PNMSj is based on SNMP Manager/Agent Technology User-friendly operation PNMSj displays a network overview with click and pull down menus to obtain detailed status information and to change the configuration of the network elements. The multiple level window structure provides easy guidance to pinpoint the PASOLINK station of concern and subsequently the component of concern. Starting with a map showing the sub-groups, followed by maps showing the various sub-group configurations, an operator can find an overview window for any PASOLINK station quickly Link oriented management and control For operational convenience, the PNMSj automatically displays the status of the opposite PASOLINK station together with key link parameters Remote access and control PNMSj Clients are able to monitor and control NEs using most Web browsers (IE, etc). Remote NEs can be accessible using either In-band or Out-of-band interface Event logging This PNMSj is useful for monitoring all events occurring within the network. It is designed to ease the maintenance and troubleshooting work on the PNMSj. The events are listed in an easy to-view formats giving the user information about the date and time it occurred, the network element where it occurred, its item and status. The User column has offered for event log that the user controlled, and showing login user name is also supported. The event log window is incorporated in the PNMSj main window. The logs are displayed at the bottom of the PNMSj screen Alarm management The Active Alarm function supports monitoring of active alarms on all connected network elements. Alarms that have been cleared in the NE will remove on the Active Alarm window and logged in the Alarm History window. The Alarm Information View is used to view the summary of current active alarms. This screen shows the list of active alarm information of NEs belonging to the same group.

EML Mgmt IP EML Mgmt Common Platform Figure 6.3 Platform architecture The modular architecture of the MS5000 system allows initial deployment with only the essential functions and sizing. Additional capabilities and capacity can be latter scaled as the network evolves. MS5000 is a sophisticated management system that provides these benefits for network administration: - Easily add new function, new NE, by plug-and-play based plug-in framework and licensing scheme - Construct scalable system depending of scale of the management network through flexible hardware allocation to logical server - Provide hardened security through advanced security functions, and thin client based GUI LCT MTD - ipasolink 200.doc

33 6.5. OSS/NMS integration MS5000 can be integrated with customer Operation Support System (OSS) and Upper NMS through Northbound Interface implemented with industry standard CORBA and SNMP protocols, to provide more comprehensive, operator-wide, system management. In addition, MS5000 supports network migration by overlaying existing NEC management systems such as PNMSj, INC-100MS, MN9100/9200, TNM, which in turn manage their respective NEs. (Planned) Then, NE can be managed through MS5000 as more functions are incorporated into MS5000 from the respective EMS/NMS.

50 10. ANTENNA AND ACCESSORIES Antenna configuration Two (2) antenna configurations are available for protection type: (1) One-antenna system using hybrid (HYB) RF combiner and divider, and (2) two-antenna system using 2 separate antennas for two ODUs. The hybrid is the passive device that combines and divides the signals between two ODUs and antenna. Note that one-antenna system requires only single antenna, however, additional loss between ODUs and the antenna have to be considered. On the other hand, two-antenna has high system gain in the same non-protection type configuration. The complete menu of PASOLINK antennas includes antennas with diameters of 0.3m up to 1.8m. They are designed to meet stringent requirements on mechanical rigidity. All PASOLINK antennas with diameters of 0.3m to 1.8m can be directly mounted to the ODU in case of 1+0 configuration. This has relevant cost and reliability merits and makes the installation quicker and easier. The PASOLINK pole mounting structure is designed in a way that the ODU can be replaced while keeping the antenna and mounting bracket, including orienteering, in place. The reflectors of the antennas are covered with white diffusive paint and the mounting structure is hot-dip galvanized.
