MPEG 2 Transport Stream Monitor

General Description The primary function of the MDD-4490 is to raise an alarm if its input MPEG Transport Stream fails. Its secondary function is to raise an alarm if the Transport Stream is not the correct stream as identified by its Stream Id. Thirdly it can raise an alarm if a particular program number is missing from the stream and in addition monitors a number of the parameters of first priority measurements of ETR290. There are 5 green status LEDs named PAT, SID, PMT, PGM and PCR. These five should be illuminated in the presence of a valid Transport Stream. 204 is another green LED that lights when the input signal is a 204 byte packet length signal. CNT is an amber LED and lights on a Continuity Count error. ASI is red and indicates a failure of the Transport Stream. There are two relays whose contacts are available on the rear assembly. They are labelled Urgent and Non-Urgent. If the Urgent relay operates then the red URG led on the front panel will light. If the Non-Urgent relay operates then the amber led NON will light. Each of the relays can be selected (by dip switches) to operate on any or all of the error states of any of the seven status LEDs. Simple Network Management Protocol (SNMP) monitoring is possible if mounted in IRT’s 4000 series frame fitted with SNMP capability. Standard features: • Raises an alarm if its input MPEG stream fails. • Raises an alarm if the ASI Transport Stream is not the correct stream as indicated by its stream ID. • Raises an alarm if a particular Program Number is missing from the stream. • Monitors a number of the parameters of first priority measurements of ETR290. • Front panel alarm LEDs and rear panel urgent and non-urgent relays. • SNMP Monitoring capability.

Configuration Stream Ident (SID): Switches SW1 to SW4 are 16 position rotary switches used for setting the Stream Id, which will be compared to that of the Transport Stream. If the MPEG stream's identification number matches the settings of SW1 to SW4, the SID LED is lit. An incorrect match can cause a non-urgent alarm if SW10-7 is set, or an urgent alarm if SW11-7 is set.

Program Number (PGM): Switches SW5 to SW8 are 16 position rotary switches used for setting the Program Number, which will be compared to the one in the Transport Stream. If a Program Number in the MPEG stream matches the setting of SW5 to SW8, the PGM LED is lit. An absence for more than 0.5 seconds of a matching Program Number in the stream can cause a non-urgent alarm if SW10-5 is set, or an urgent alarm if SW11-5 is set.

Urgent / Non-urgent Alarm settings: Switches SW10 and SW11 are 8 way Dual-In-Line (DIL) switches used for selecting the conditions that will cause the Urgent and Non-urgent alarms to occur. On SW10, operation of the switches associated with PAT, SID, PMT, PGM, PCR and 204 will cause a Non-urgent alarm when the associated LED extinguishes. In the case of ASI and CNT, operation of their associated switches will cause a Non-urgent alarm when the LEDs turn on. SW11 is used in a like manner for the Urgent Alarm. It is possible to set a condition to raise both an Urgent and Non-urgent alarm. An alarm condition (or loss of power) causes a ground to appear on the appropriate Rear assembly pin.

SNMP

What Is It? SNMP stands for Simple Network Management Protocol. It is an application layer protocol for managing IP (Internet Protocol) based systems. SNMP enables system administrators to manage system performance, and to find and solve system problems. SNMP runs over UDP (User Datagram Protocol), which in turn runs over IP. Three types of SNMP exist: SNMP version 1 (SNMPv1), SNMP version 2 (SNMPv2) and SNMP version 3 (SNMPv3). It is not the intention here to discuss the differences between various versions, only to bring attention to the fact that IRT Electronics modules, fitted with SNMP capability, use SNMPv1. An SNMP managed network consists of three key components: Network Management Systems (NMS), agents, and managed devices. An NMS is the console through which the network administrator performs network management functions, such as monitoring status (e.g. alarm states) and remote controlling, of a set of managed devices. One or more NMSs must exist on any managed network. Generally the NMS is a computer running third party SNMP control software. There are a number of third party SNMP software applications currently available on the market. An NMS polls, or communicates with, an agent. An agent is a network management software module that resides in a managed device. An agent has local knowledge of management information and translates that information into a form compatible with SNMP. The agent, therefore, acts as an interface between the NMS and the managed devices. The NMS sends a request message, and control commands for the managed devices, to the agent, which in turn sends a response message, containing information about the managed devices, back to the NMS. A managed device contains an SNMP agent and resides on a managed network. Managed devices collect and store management information and make this information available to NMSs using SNMP. Managed device agent variables are organised in a tree structure known as a Management Information Base (MIB). Within the MIB are parameters pertaining to the managed device. An Object Identifier (OID) number within the MIB defines the managed device type. This is a unique number specific to the model of managed device. Other information relating to the device is also stored, information such as alarm states, controllable settings, etc. The MIB tree is organised in such a way that there will be no two MIB files with conflicting placements. Normally an NMS polls an agent for information relating to the MIB in a managed device to be sent back to the NMS. When certain conditions are met within the MIB, such as major alarm conditions, for example, the agent automatically sends what is known as a trap to the NMS without any prompting from the NMS. This allows automatic notification of a predetermined event.

SNMP with IRT Products IRT Electronics currently employs SNMPv1 with its 4000 series frame. The frame acts as an agent when fitted with a CDM-4000 module. This module has its own designated slot next to the power supply so as to not affect the number of modules that the frame will take. Communication between the NMS, the frame and its loaded modules are via this CDM-4000 module. Note that the NMS software is third party and not supplied by IRT Electronics. Ethernet connection for SNMP operation is via an RJ45 connector on the rear of the frame, below the mains inlet. Ethernet rate runs at either 10 baseT or 100 baseT. Frame parameters, such as Name, Address and Location, are set via an RS232 interface, a D9 connector on the rear of the frame below the mains inlet. A software terminal emulator, such as Tera Term or HyperTerminal, is used for setting and reading the parameters of the frame. IRT modules that are SNMP compatible need a plug-in SMU-4000 module with a program relevant to the module that it is plugged into. Depending on the module, besides the module identification, parameters such as alarm states, inputs and controls etc. are communicated to the CDM-4000 agent via a data bus on the rear of the frame. Thus the CDM-4000 collects information on what is loaded within the frame, what positions they occupy, and their current status for communication to the NMS when the NMS sends a request for information. In the event of a major alarm from any of the SNMP compatible modules, or power supplies, a trap is automatically sent by the CDM-4000 agent to the NMS without any prompting by the NMS. This alerts the operator to any fault conditions that may exist that need immediate attention.

Installation Pre-installation: Handling: This equipment may contain or be connected to static sensitive devices and proper static free handling precautions should be observed. Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures should be followed when inserting or removing cards from these bags. Power: AC mains supply: Ensure that operating voltage of unit and local supply voltage match and that correct rating

fuse is installed for local supply. DC supply: Ensure that the correct polarity is observed and that DC supply voltage is maintained within

the operating range specified. Earthing: The earth path is dependent on the type of frame selected. In every case particular care should be taken to ensure that the frame is connected to earth for safety reasons. See frame manual for details. Signal earth: For safety reasons a connection is made between signal earth and chassis earth. No attempt should be made to break this connection. Installation in frame or chassis: See details in separate manual for selected frame type. Signal Inputs: An ASI signal to be monitored is connected to the BNC connector on the rear of the rear connector assembly. For configuration of the MDD-4490 to match selected operating alarm states, see the configuration section of this manual. Alarm Outputs: Two relay alarm outputs, non-urgent and urgent, are via PL1, a 4 pole Phoenix style screw terminal block, on the rear connector assembly. Pin 1 switches to ground when a non-urgent alarm status has been raised. Pin 3 switches to ground when an urgent alarm status has been raised. Pins 2 and 4 are grounds. Front panel LEDs also light up when either of these alarm states has been raised.

Maintenance & storage Maintenance: No regular maintenance is required. Care however should be taken to ensure that all connectors are kept clean and free from contamination of any kind. This is especially important in fibre optic equipment where cleanliness of optical connections is critical to performance. Storage: If the equipment is not to be used for an extended period, it is recommended the whole unit be placed in a sealed plastic bag to prevent dust contamination. In areas of high humidity a suitably sized bag of silica gel should be included to deter corrosion. Where individual circuit cards are stored, they should be placed in antistatic bags. Proper antistatic procedures should be followed when inserting or removing cards from these bags.
