1 Applicable Version

Fig. 1 Applicable Version

This document describes protocol stack and network parameters for NMS (Network Management System) implemented in an SV (Supervisory) card which is a main controller for an NE (Network Element) of SRT 1F series digital microwave radio equipment. The document also shows all NMS management objects supported by SNMP (Simple Network Management Protocol) and/or SRT1F Web LT (Web based Local craft Terminal for SRT1F) on the NE.

A person who refers this document for NMS design and SRT 1F operation, should be familiar with SRT 1F, a PC (Personal Computer), an operating system, an application software usage on the PC and basic of IP (Internet Protocol) network.

NMS of SRT 1F is designed on SNMP and HTTP (Hyper Text Transfer Protocol). SV card, main controller installed in the SRT 1F, is composed both an SNMP embedded agent and a web server. These facilities provide integrated NMS environment among SRT 1F and various type of equipment such as MUX, ADM, routers and another vender’s radio equipment thanks to SNMP, and good accessibility by HTTP which is not depend on management platform. SV card has two (2) Ethernet port and two (2) DCC (Data Communication Channel) terminations from radio/line sides as a connection port for NMS.

Figure shows block diagram of the NMS facilities on the SV card.

Fig. 3 Role of the SNMP agent and the web serve

Interconnectivity between Ethernet LAN connection and DCC line is realized by on-board HUB function on the SV. All of the NMS connection port, two (2) Ethernet LAN and two (2) DCCs are connected each other via the HUB. This HUB is a simple repeater HUB, so that packet routing function of any protocol layer is NOT supported by SRT 1F.

As a basic concept, NMS of SRT 1F is designed that SRT1F Web LT and SNMP are split up the equipment management work. SRT1F Web LT has full operational function such as configuration, control and performance monitoring, and is used for a main human machine interface for operation, maintenance and system setup. SNMP mainly provides an open interface for fault management and performance monitoring to a central equipment management system.

Table shows a role of the embedded SNMP agent and the SRT1F Web LT on the SV.

4 Network Layer

Fig. 8 Parameters of Network layer

Table shows parameters of Network layer protocol on Ethernet LAN connection. The LAN connection port on the equipment is designed based on IEEE Recommendations. The LAN port supports both connection speed of 10Base-T and 100Base-TX. Connection speed is automatically detected and negotiated with a connected equipment. For a physical cable connection to an external LAN equipment, straight and cross cable can be use without care. SRT 1F automatically detects the plugged cable type.

4.1 SNMP

Fig. 9 Parameters of SNMP

Table shows parameters of SNMP on Application layer. SNMP is mainly used for connection between the embedded SNMP agent and SNMP managers that is a central performance and fault management system. SNPM uses UDP/IP as a low layer protocol for connection.

SRT 1F can communicate with maximum three (3) managers. Access from the managers are controlled by an IP address and a community name. They can set independently for each manager.

Port 161 (Listen) No

Access Control 1

1 SRT 1F checks the IP address and the community name in the received GET Request mes-sage. If the IP address differs from pre-set one to the NE, the received message is discarded and no message is responded to the manager. If the IP address is correct but the community name differs, SRT 1F sends authentication Failure trap message to the manager.

5 Additional Function

Fig. 10 Summary of additional functions

In addition, SRT 1F has an SNTP client. Real time clock in an NE can be synchronized periodically to an NTP server clock built in an NMS network. This facility provide that all NEs in the NMS network can be synchronized in one clock if necessary.

SRT 1F can responds to a Ping command. This will be very useful for health check and trouble shooting of an equipment and a network.

DNS (Domain Name Service) is not supported. A target SNMP manager and an NTP server must be set by IP address.

Table shows summary of additional functions.
