RANGE OF VARIABLES Traditional network technology boundaries are now being crossed with technologies such as Asynchronous Transfer Mode (ATM), Digital European Cordless Telephone (DECT), ISDN, and intelligent networks. Network systems and products vary considerably across the specific technologies and are usually unique to a particular vendor In broad terms technologies can be described as: switching, transmission, radio (fixed and mobile), video and satellite Transmission medium may be: copper cable, coaxial cable, optic fibre cable, radio, video, satellite Network Architecture can be described as; Analogue (to be phased out by 2000), PDH (plesiochrynous digital hierarchy), SDH (synchronous digital hierarchy), ATM Network hierarchy can be described as backbone, transport, broadband, data, HLS, CLS A four (4) tier maintenance regime exists within the industry. This consists of: Tier 1 - remote and/or first in repair/rectification Tier 2 - specialist repair/rectification Tier 3 - network support - network/system/equipment specialist Tier 4 - vendor support The level of fault rectification varies from enterprise to enterprise, but revolves around fault clearance time, customer impact and alarm priority. Alarm priorities are enterprise specific but generally consist of four (4) levels Priority 1 impact - demanding immediate attention Priority 2 degradation - decision to be made as to attention given and depends on impact on both network and customer Priority 3 hazardous - attention given as part of normal activities Priority 4 no action - alarm noted Escalation is usually through the tiers, but can vary again depending on the nature and impact of the problem. Decision for vendor involvement rests with tier 3 alone, and generally tier 3 and tier 4 work together on problem resolution Alarm/fault handling procedures are clearly specified within enterprise instructions and guidelines, along with the enterprise policy relating to fault/problem escalation Network problems could include: faults, capacity, customer complaints, warnings on problems about to occur, security violations Problem indicator could include: alarm, trouble reports, customer complaints Problems may be identified by: alarms, carriers, customers, service providers Outages are classified as minor and major and whilst the definition may vary from carrier to carrier, the difference is usually about 120 customers, 15 minutes for restoration, 140 meg system

A further category of outage relates to disaster which involves flood, bushfire, loss of multiple optical fibres e.g Reaction time to alarms can vary between carriers. Normally response is influenced by time/day of the week and service level agreements with customers. Service level agreements dictate priorities Relevant legislation, codes, regulations and standards include: ACA standards as they apply to carrier operation International Standards ISO 9000 and 9001 ITU recommendations - network management series E410 Occupational Health and Safety Privacy Act

A four (4) tier maintenance regime exists within the industry. This consists of: Tier 1- remote and/or first in repair/rectification Tier 2 - specialist repair/rectification Tier 3 - network support - network/system/equipment specialist Tier 4 - vendor support The level of fault rectification varies from enterprise to enterprise, but revolves around fault clearance time, customer impact and alarm priority. Escalation is usually through the tiers, but can vary again depending in the nature and impact of the problem. Decision for vendor involvement rests with tier 3 alone, and generally tier 3 and tier 4 work together on problem resolution Alarm/fault handling procedures are clearly specified within enterprise instructions and guidelines, along with the enterprise policy relating to fault/problem escalation Each component of the network has its own alarm management systems which are self monitoring and usually have built in error counters. Such systems are normally centralised and are physically monitored Alarm details recorded are: Colours, codes, node affected, date and time, new or old record Alarms could result from: new installation, planned outage, network failure, faulty circuits, security breaches, animal damage, traffic overloads, Customer Premises equipment problems, peak traffic loads Alarm types are usually equipment/product or vendor specific and can include: high errors, low errors, loss of signal, AIS, power supply failure, degraded performance, alarm indicating system, loss of optic receiver, laser shutdown/failure, receive signal fail, pilot failure, transmit failure, modulator failure, demodulator failure, digital alarms, low transmitter power, loss of line, high and low deviation, data, VSWR,door, over temperature Conditions which may not generate an alarm may be: no dial tone, cut offs, noise, clicking, hums, one way transmission, fading, errors Alarm priorities are enterprise specific but generally consist of four (4) levels Priority 1 impact - demanding immediate attention Priority 2 degradation - decision to be made as to attention given and depends on impact on both network and customer Priority 3 hazardous - attention given as part of normal activities Priority 4 no action - alarm noted Hardware faults may include: blown fuses, connectors, wiring, cards and card components, antennas, feeders, cable, weather damage, lightning damage Customers may be internal or external to the organisation and may include other carriers All enterprises have specific policies relating to outage situations and the action to be taken Escalation procedures are enterprise specific and can relate to both alarm type and repair time Variables that may impact on system faults may include: recent additions to system, building works, operator error, power supply, software problems, time of fault, atmospheric conditions. Service agreements are maintenance agreements between communication companies and their clients and vary from company to company and with the type of equipment owned or leased by the client.

RANGE OF VARIABLES Traditional network technology boundaries are now being crossed with technologies such as Asynchronous Transfer Mode (ATM), Digital European Cordless Telephone (DECT), ISDN, and intelligent networks. Network systems and products vary considerably across the specific technologies and are usually unique to a particular vendor In broad terms technologies can be described as: switching, transmission, radio (fixed and mobile), video and satellite Transmission medium may be: copper cable, coaxial cable, optic fibre cable, radio, video, satellite Network Architecture can be described as; Analogue (to be phased out by 2000), PDH (plesiochrynous digital hierarchy), SDH (synchronous digital hierarchy), ATM Network hierarchy can be described as backbone, transport, broadband, data, HLS, CLS A four (4) tier maintenance regime exists within the industry. This consists of: Tier 1 - remote and/or first in repair/rectification Tier 2 - specialist repair/rectification Tier 3 - network support - network/system/equipment specialist Tier 4 - vendor support The level of fault rectification varies from enterprise to enterprise, but revolves around fault clearance time, customer impact and alarm priority. Escalation is usually through the tiers, but can vary again depending in the nature and impact of the problem. Decision for vendor involvement rests with tier 3 alone, and generally tier 3 and tier 4 work together on problem resolution Alarm/fault handling procedures are clearly specified within enterprise instructions and guidelines, along with the enterprise policy relating to fault/problem escalation All work undertaken on a first in basis is under instruction from the network management/control centre. Advice to repairer is communicated either by phone or ticket of work, dependent on nature of the problem and its priority

Network hierarchy can be described as backbone, transport, broadband, data, HLS, CLS A four (4) tier maintenance regime exists within the industry. This consists of: Tier 1 - remote and/or first in repair/rectification Tier 2 - specialist repair/rectification Tier 3 - network support - network/system/equipment specialist Tier 4 - vendor support The level of fault rectification varies from enterprise to enterprise, but revolves around fault clearance time, customer impact and alarm priority. Escalation is usually through the tiers, but can vary again depending in the nature and impact of the problem. Decision for vendor involvement rests with tier 3 alone, and generally tier 3 and tier 4 work together on problem resolution Alarm/fault handling procedures are clearly specified within enterprise instructions and guidelines, along with the enterprise policy relating to fault/problem escalation Faults may include: blown fuses, connectors, wiring, cards and card components, antennas, feeders, cable, weather damage, lightning damage Fault escalation procedures are defined by the enterprise and usually relate to appropriate repair times Tests may include; DC/AC measurements,error, continuity, noise level, return loss, spectrum analysis, radio on receiver sensibility, surveys - mobile phones/pager, end to end, line levels both in and out, transmitter power, transmitter frequency, transmitter deviation, receiver frequency and sensitivity, level and quality of demodulated output - audio/bit error rate, antenna sweep measurements Test equipment may include: multi meters, communication testers, transmission measuring sets, directional couplers, lap top computer Tools may include: screwdrivers, pliers, cutters, wire strippers, soldering iron, insulation displacement tools, cable termination tools Transmission medium may be: Fibre, cable, radio, satellite, microwave, video Each component of the network has its own alarm management systems which are self monitoring and usually have built in error counters. Such systems are normally centralised and are physically monitored Alarms could result from: new installation, planned outage, network failure, faulty circuits, security breaches, animal damage Alarm types are usually equipment/product or vendor specific and can include: high errors, low errors, loss of signal, AIS, power supply failure, degraded performance, alarm indicating system, loss of optic receiver, laser shutdown/failure, receive signal fail, pilot failure, transmit failure, modulator failure, demodulator failure, digital alarms, low transmitter power, loss of line, high and low deviation, data, VSWR,door, over temperature Conditions which may not generate an alarm may be: no dial tone, cut offs, noise, clicking, hums, one way transmission, fading, errors Hardware faults may include: blown fuses, connectors, wiring, cards and card components, antennas, feeders, cable, weather damage, lightning damage Conditions which may not generate an alarm may be: no dial tone, cut offs, noise, clicking, hums, one way transmission, fading, errors, animal damage

Network Architecture can be described as; Analogue (to be phased out by 2000), PDH (plesiochrynous digital hierarchy), SDH (synchronous digital hierarchy), ATM Network hierarchy can be described as backbone, transport, broadband, data, HLS, CLS A four (4) tier maintenance regime exists within the industry. This consists of: Tier 1 - remote and/or first in repair/rectification Tier 2 - specialist repair/rectification Tier 3 - network support - network/system/equipment specialist Tier 4 - vendor support The level of fault rectification varies from enterprise to enterprise, but revolves around fault clearance time, customer impact and alarm priority. Alarm priorities are enterprise specific but generally consist of four (4) levels Priority 1 impact - demanding immediate attention Priority 2 degradation - decision to be made as to attention given and depends on impact on both network and customer Priority 3 hazardous - attention given as part of normal activities Priority 4 no action - alarm noted Escalation is usually through the tiers, but can vary again depending in the nature and impact of the problem. Decision for vendor involvement rests with tier 3 alone, and generally tier 3 and tier 4 work together on problem resolution Alarm/fault handling procedures are clearly specified within enterprise instructions and guidelines, along with the enterprise policy relating to fault/problem escalation Each component of the network has its own alarm management systems which are self monitoring and usually have built in error counters. Such systems are normally centralised and are physically monitored Alarms could result from: new installation, planned outage, network failure, faulty circuits, security breaches, animal damage Alarm types are usually equipment/product or vendor specific and can include: high errors, low errors, loss of signal, AIS, power supply failure, degraded performance, alarm indicating system, loss of optic receiver, laser shutdown/failure, receive signal fail, pilot failure, transmit failure, modulator failure, demodulator failure, digital alarms, low transmitter power, loss of line, high and low deviation, data, VSWR,door, over temperature Conditions that may not generate an alarm may be: no dial tone, cut offs, noise, clicking, hums, one way transmission, fading, errors, animal damage Transmission systems are governed by international standards set by the ITU Relevant legislation, codes, regulations and standards include: International Standards ISO 9000 and 9001 ACA Standards TS 14 ITU recommendations Occupational Health and Safety Privacy Act Private property law
