Log In Sign Up. High accuracy clock supply functions for packet synchronization Efficient usage of frequency resourses Frequency agility and easy tuning Adaptive modulation radio AMR Piasolink polarization interference canceller XPIC Precision clock synchronization protocol IEEE v Link oriented management and control Remote access and control E1 interface for optional card slot STM-1 optical interface for optional card slot STM-1 electrical interface for optional card slot Power line inlet for power supply slot Multiple service engine for optional card slot Moving into unified IP packet networks and end-to-end network management allow you to offer premium services including conventional voice service over packet lpasolink 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.

All this is achieved without any header suppression or elimination of packet data. The modular construction with universal card slots and integrated management software ensures operation continuity and upgradability from each hop or node. 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.

These are briefly listed as follows; – Native TDM and packet transmission enabling ipasolijk migrate into carrier-grade full packet radio with scalable throughput capability. As an example of iPASOLINK, you can double the transmission capacity up to Mbps over a single radio frequency utilizing both polarizations without any requirement of neither additional outdoor foot prints nor indoor mounting spaces.

These are factory options. Up to Mbps by single polarization and Mbps by dual polarizations for Ethernet packet transmission. Incorporation of energy save integrated digital processing techniques and adoption of high efficiency RF components. The transmission methods are as follows: Hybrid switching function Independent packet switching and cross-connection functions are provided on the single platform.

Up to 20 Gbps -TDM cross-connect: Advanced QoS function Ipasolnk QoS functions control finely tuned bandwidth and priority on a per-flow basis without any impact on traffic forwarding performance to provide flexible and commercially viable packet traffic. PWE enables transport of non-IP based services over IP network, resulting in cost reduction and network consolidation. Radio Link Aggregation Radio Link Aggregation achieves high capacity and resiliency transport with bundling several radio links.

The distribution algorithm distributes the packet according to: High accuracy clock supply functions for packet synchronization Supports native TDM and Synchronous Ethernet transmissions. A card for synchronous Ethernet is provided. Efficient usage of frequency resourses – High modulation scheme up to QAM for native Ethernet and native TDM transmission achieves high spectrum efficiency.


Limited within the specified sub-band in ODU.

Alteration of sub-band can be achieved by replacement of RF filter. 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. In the IP packet transmission, i. 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.

Maximum throughput at 64 byte VLAN tagged frame passed rate base. The additional required components from single pole transmission are; dual-polarized antenna, one more ODU, associated software key in IDU. Through these additions, you can achieve double capacity without additional footprint or indoor mounting space. Maximum throughput at 64 byte VLAN tagged passed jpasolink base. Synchronization application Figure 3.

Near-end baseband, Far-end baseband and IF loopback – Remote upgrades capabilities. In contrast, Packet data traffic is gradually increasing. However; – Amount of required bits for data service is much larger than those for voice and significant bit-cost reduction is absolutely required.

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 ioasolink might be a mandatory requirement to survive this highly competitive field: With all these considered, it is clear that migration to all-packet mobile networks is the way ipasolinkk.

All-IP ipasollink strategy of existing 3GPP Release operators might be different from other mobile operators due to difference of mobile architectures adopted. It is free from time and synchronization issues. However, TDM network can ipasklink manage the growth of data ipasollnk efficiently.

Ipaasolink 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 ipassolink synchronous delivery of data. Therefore, synchronization issue due to fluctuation of delay, latency or jitter must be carefully considered in transmission of mobile service. 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, onto other cost effective IP network.

The benefit of traffic offloading is twofold: Therefore, adoption of Dual Native backhaul would be risk-free, ipxsolink most flexible and cost effective migration method towards all-IP network. Dual native transmission is the most suitable solution in this application. The connection line is only one coaxial cable.

Antenna 11 – 42 GHz Figure 5. Antenna system for adjacent channel or co-channel assignment. Web applet is installed in IDU. PNMSj has the features as bellow: 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 ipaasolink provide an easy, single glance, overview of an entire network.

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. 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. Ipaolink NEs can be accessible using either In-band or Out-of-band interface. It is designed to ease the maintenance and troubleshooting work on the PNMSj.


The events are listed in an easy—to-view formats giving i;asolink user information about the date and time it occurred, the network element where ioasolink 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 Kpasolink 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.

The list also shows what alarm severities are currently active in the NE and whether it has been acknowledged or not. The total count of current active alarms in each category is shown at the top of the main window.

Security Users are registered by means of a login name and password. To protect the network and network management system from unauthorized access or unauthorized modifications, the privileges are assigned to the groups rather than to the individual user.

A user will have the privilege provided to the group where it belongs. Moreover, the control of network elements can be customized and provided only to specific groups.

This allows the administrator a high-flexibility of assigning not only the PNMSj functions but also the control and management of individual NE. MS architecture is illustrated in the figure below. Additional capabilities and capacity can be latter scaled as the network evolves.

MS is a sophisticated management system that provides these benefits for network administration: Path management This area focuses on establishing and maintaining relationship of the path in each layer L1, L2 and Optical.


End-to-end paths for microwave and optical equipment, and end-to-end paths between Ethernet termination points can be created, as well as redundant paths used to re-route traffic in case of primary route failure. Performance management Ensuring performance of the network is of utmost importance to network administrators, as this leads to customer satisfaction and confidence.

Therefore, MS provides interfaces to monitor and store various performance indicators. These data can be exported for further processing or displayed in a graphical view for fast trend analysis. By this function, undesirable packet is not transferred to management port and secured management system is achieved.
