1. INTRODUCTION To provide reliable digital access links and fully exploit the potential of end-to-end advanced networks, NEC has developed the e-PASOLINK, a narrow band point-to-point microwave relay system operating at radio frequency (RF) band of 80 GHz. This system meets an increasing demand for digital transmission services and will satisfy the needs for common carrier access links, private links, urban area networks, rural area networks, temporary networks or emergency links for data and transmission and feature sufficient capacity to simultaneously support legacy TDM and rapidly-growing IP traffic. The e-PASOLINK offers very high performance with large system flexibility, easy to install, field proven reliability and cost effective but also robust and scalable to accommodate future application and capacity needs. The e-PASOLINK system provides interface module types of SDH/SONET and LAN and supports transmission rates of up to 1200 Mbps. The system is a single all outdoor unit that provides simultaneous connection of native SDH/SONET and native Ethernet.

2.7. ARM (Adaptive Rate Modulation)

2.7.1. Introduction e-PASOLINK’s ARM (Adaptive Rate Modulation) feature provides gradual adaptive data rate and modulation changes to the transmission that alters the modulation type and/or changes the signal bandwidth, allowing the link to maintain high availability connections during rain fades. As anomalies in the path reduce signal levels, e-PASOLINK shifts the modulation from QPSK to BPSK, and capacity decreases in incremental steps. The internal engine provides the necessary prioritization of the Ethernet and SONET/SDH traffic to maintain quality of service at the new data rate. Once the anomaly subsides, E-Band PASOLINK automatically restores transmission capacity.

2.7.2. ARM range Table 2 shows the ARM range for Channel spacing and modulation scheme.

Baseband Module The Baseband Module (BBM) provides multiple network interfaces to connect the outside world to the radio. Up to four SONET/SDH interfaces are supported through SFP modules interface. Up to additional Ethernet interfaces are supported through a second SFP modules interface and one 10/100/1000 copper Ethernet interface with standard RJ-45 connector. All of the Ethernet interfaces are connected to an Ethernet switch. The Ethernet switch and the SONET/SDH interfaces are connected to an FPGA with multiple high-speed SERDES interfaces. The FPGA combines the multiple data streams, formats the data, adds forward error correction coding and optional encryption. The resulting high-speed data streams are output to the IFPS. The FPGA also processes the high-speed received data from the IFPS.

IFPS Module The IFPS Module has three main functions: provides the transmitter path from the BBM to the FEH, provides the receiver path from the FEH to the BBM, and regulates the external 48 VDC power down to the main 5.5 V supply rail for the radio.

FEH Module The FEH Module has four main functions: up convert the transmit IF signal to millimeter-wave frequencies, down convert the receiver millimeter-wave to the receive IF frequency, combine the millimeter-wave TX and RX signals into one antenna port, and provide a millimeter-wave loopback path for testing and debug.

Ethernet L2 Switch This switch has four (4) SFP’s and one (1) RJ45 port available for external network devices connection. It contains interfaces connected to management control unit and to Primary & Secondary radio interfaces. Any combination of ports can be used to carry traffic across the link.

SONET/SDH INF The SONET/SDH traffic is handled separately within the radio & does not pass through internal switch. Up to four SONET/SDH Interfaces are supported through an SFP modules interface. .

Power Supply The nominal power supply voltage is –48 VDC. However, the range of the unit is –37.5 to –75 VDC.

4.3. Features

4.3.1. 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.

4.3.2. 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.

4.3.3. Link Oriented Management and Control For operational convenience, the PNMSj/PNMTj automatically displays the status of the opposite PASOLINK station together with key link parameters.

4.3.4. 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 LAN interface.

4.3.5. 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.

4.3.6. 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. 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 (Not Ack and Total) in each category is shown at the top of the main window.

4.3.7. ITU-T G.826 Performance Monitor The PNMSj is able to retrieve the performance data of all listed PASOLINK stations and their associated microwave link in accordance with ITU-T specification G.826.

- Scheduled or on-demand upload

- Report or chart presentation

- Threshold setting and alerts

4.3.8. 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. Lastly, users and groups created in PNMSj are internal to PNMSj only and do not correspond to Windows users and groups.

4.3.9. SNMP Interface PNMSj provides an SNMP interface to make the PASOLINK equipment an integral part of a higher level of network management system.
