An NMS is used for radio link management i e monitors the device s operating status routes intelligent management information calculates the performance of a radio link locates faults and the operation mode It can provide a lot of available information on devices and form reports for users The IDU uses the SNMP protocol to provide information the physical layer s performance All control and monitoring is managed by a computer through an RJ45 jack NMS supports SNMPC and HP Openview amongst others The use of NMS is optional e Radio management stage Management is divided into 3 stages gt Low level management device stage Completed by CPU in the IDU which monitors and controls the device modules including collecting alarms calculating performance configuration safety protection etc Second stage Microwave link stage When the radio is working this stage monitors using a computer connection to the radio there is collection of information using an SNMP agent in the IDU the agent collects information and sends it to the NMS Third stage telecom network management stage This stage entails management of the larger scale telecom network There is a NMS center which manages more than two SNMP agents within IDU s thereby allowing complete management of the entire network The SGT LPN radio can be linked to the Internet NMS includes SNMP G 821 and can monitor every device using LAN or WAN 49 SGT LPN
