SYSTEM OVERVIEW
The PASOLINK Network Management System comprises three elements, a high performancecomputer with peripheral equipment, a software package called PASOLINK Network managementsystem (PNMS) and PASOLINK Management Card (PM CARD, only for PASOLINK) to be equippedin the PASOLINK equipment.
The PNMS is located at a central or a regional operation center and enables network operators tomonitor and control the PASOLINK / PASOLINK
+network and its elements remotely. Alternatively, a
laptop computer with simplified software package, called PASOLINK Network Management Terminal(PNMT) is available for maintenance purpose.
A PASOLINK/PASOLINK+
NE at the central site interfaces with the PNMS through one of thefollowing interfaces.
- PASOLINK : RS232C 19.2/9.6kbps, Async (through Router)
- PASOLINK+
:10BASE-T(LAN) or V.11 19.2kbps, Async (through Router)
Communication to the Remote PASOLINK/ PASOLINK+

KEY COMPONENTS
PNMS
Sun Workstation with its peripheral equipmentand UNIX operating system is used to support
PNMS software.
It provides a central access point to monitor andcontrol the entire network remotely. The PNMSsoftware provides map viewing of the entirenetwork as well as its individual subnetworks.
The PNMS provides means to edit, upload, anddownload the configuration files to each of the
PASOLINK / PASOLINK+
network elements.
Multi-level access privileges are implemented toensure the security of the system.
PNMTA mobile terminal such as of a laptop PCrunning Windows 2000/NT/98/95 Operatingsystem containing a simplified version of thePASOLINK Network Management softwarecalled PNMT, is provided for maintenancepurpose.
This configuration can monitor and control a
single PASOLINK / PASOLINK+
link at a time.
Any link through the network, connected via
digital service channel, can be monitored andcontrolled remotely from the laptop.
PM Card (only for PASOLINK)
The PASOLINK Management Card (PM CARD)is an optional plug-in module for NEC'sPASOLINK Indoor equipment.
The PM CARD handles the communicationbetween the PASOLINK network elements andthe Network Management system. It collects upto 300 event logging data and up to seven daysof performance data.
The PM CARD can either connect permanentlyor occasionally to the NMS. The PM CARDcommunicates with each other via one of theservice channels. It serves as a single accesspoint and enables the remote access to anyPASOLINK in the network.

BASIC FUNCTIONS -PNMS-
Status Monitoring and Display
The PNMS monitors the status of the
PASOLINK / PASOLINK+
stations by way of
polling mechanism. Detection of a status changeor failure to report at one of thePASOLINK/PASOLINK
+stations will result in a
color change on the display and if appropriate, inan audible alarm.
The multi-level windowing structurecorresponding to different map levels provideseasy guidance to pinpoint to the PASOLINK /
PASOLINK+
station of the concern and
subsequently to its components.
For ease of operation and quick reference, thePNMS automatically displays the status of the
opposite PASOLINK / PASOLINK+
station with
its key link parameters.
As shown in the figure to the right, key
components of PASOLINK / PASOLINK+
such
as the outdoor unit (ODU), indoor unit (IDU) andthe PASOLINK Management Card (PM CARD,only for PASOLINK) are distinguished. Thedetailed information for each of thesecomponents can be found in the subsequent
windows.
Remote Control
The PNMS software provides remote control ofvarious link related parameters such as transmitpower and frequency allocation.
Auxiliary Input/OutputSix photo-coupler input ports and four relayoutput ports are available in the PASOLINK /
PASOLINK+ equipment to allow monitoring andcontrolling of the miscellaneous equipment atsite.
The types of alarm and control for these portscan be defined freely by the operator.

UPPER MANAGEMENT INTERFACE (OPTIONAL)
In order to make NEC's PASOLINK / PASOLINK+
equipment an integral part of an upper
management system, an optional SNMP interface is provided with the PNMS. The interface is basedon SNMPv1 and resides on the same WS as the PNMS. The detailed control and data gathering areperformed by the PNMS. The summarized alarm traps (Summary SNMP trap such as Group of NE
summary trap or NE summary trap) are notified to upper management system through this interface.
The optional X-terminal can be connected to the PNMS through LAN interface using X-protocol. Thenetwork operator can use an X-terminal to perform almost all the functions of the PNMS. In case ofupper management system receives summary traps from PNMS, the operator need to access PNMSwindow on X-terminal for the detail.
In addition, as each PASOLINK / PASOLINK+
also has SNMP interface in itself, each PASOLINK/
PASOLINK+
is directly accessible from upper management system if required.
The interface to the upper management is UDP/IP with Ethernet interface. Even though the LANinterface is pre-configured by the work station, 10BASE-x are assumed.
