TECHNICAL SPECIFICATION

(MAINTENANCE PLAN)

1.0 NETWORK BRIEF

POWERGRID has established a Digital Microwave communicationnetwork by installing PDH transmission & Radio system of NOKIA makealong with NMS/100 Network Management system. The network spansover eight different states of Northern India.

Simultaneously, to complete their Wide-Band Communication Network (WBCN), POWERGRID established a number of fiber-optic linksthroughout the northern region. The equipment is installed in the premisesof POWERGRID and other constituents of the SC&C-NR project. In thisspecification term POWERGRID also implies POWERGRID orConstituents . The PDH transmission systems is primarily composed of primary order multiplexes along with Channel units, Digital cross connect equipmentand DMR 2000 Microwave Radios. In order to monitor all these network elements, NMS/100 Network Management system has been commissionedat NMS Control room, New Delhi and X-terminals at all the SLDC’s of the constituents.

Continuous availability of the WBCN with a guaranteed System

Availability (SA) of 99.9% is most essential requirement. To achievedesired SA, POWERGRID intends to enter into a maintenance contract for maintaining the wideband network equipment (FO&MW). Activities,

procedures, responsibilities of employer & contractor towards maintainingthe wideband network are described as following

1.1 PROJECT FACTS

The Northern region power system interconnects the generation,transmission and distribution facilities of various constituents (StateElectricity Utilities) in 8 states as indicated below:

- Delhi- Himachal Pradesh- Haryana- Punjab- Jammu & Kashmir - Rajasthan- Uttar Pradesh

The vast expanse of network along with the substantial numbers of equipment, demands proper placement of manpower at strategic locations in order to provide required systemavailability during maintenance period. The manpower placement plan andimplementation philosophy is described in details in subsequent sections of thisdocument. Contractor will have to make their own assessment of the network and deploymanpower accordingly to achieve system availability of 99.9%. Availability calculationwill be done separately for MW & FO network and average of both shall be taken.However, in no case less than specified manpower of requisite qualification are to bedeployed.

2.0 OPERATION AND MAINTENANCE SET-UP

Both POWERGRID and the contractor have important roles to play in theoperation & maintenance of the installed wideband network.

2



2.1 RESOURCE DEPLOYMENT

In order to cover the entire network it is imperative that contractor’s maintenanceengineers are strategically located so as to reach the site within shortest possible

time frame. Thus a minimum of four (4) service Engineers in addition tomaintenance coordinator will be deployed at four (4) strategic locations (one person each at New Delhi, Chandigarh, Lucknow and Jaipur), this however, doesnot relieve the contractor from its obligation to maintain required systemavailability of 99.9% accordingly contractor shall asses the actual manpower requirement and place them suitably at others locations if required. The centralcontrol and monitoring of transmission system will be performed from RSCC in

New Delhi by means of the NMS. The other locations will work under thecontrol/instructions of the Coordinator located in New Delhi. The control andreporting philosophy will be as indicated below:

2.2 Monitoring

Network will be monitored by POWERGRID through NMS at RSCC (RegionalSystem coordination & Control Centre at New Delhi). Network Monitoring Team(NMT), whenever, notices any fault/abnormality in the system shall notify to thecontractor’s maintenance coordinator at New Delhi, over phone with an event no.An event report shall be generated by POWERGRID as per enclosed FORMATappended at Annexure-I. On issuance of Event Report (may be recorded over

phone in case of non-availability of contractor’s representative at RSCC) by NMTcorrective action/s shall be carried out by contractor’s maintenance personnel for rectification. Contractor’s representative must report within four (4) Hours atlocations where contractor’s engineers are stationed and within reasonable timeat all other locations which shall in no case exceed more than 12 Hrs (includingtravel time). Time mentioned here is irrespective of normal working Hrs or holidays.

The Network Monitoring Team shall co-ordinate and control any site visits toensure that WBCN is operating with a minimum of disruptions during these visits.The Network Monitoring Team will inform the relevant POWERGRID /constituent to facilitate the access to the site/equipment where fault is suspected.

The main responsibilities of the POWERGRID’s Network Monitoring Team are:

• WBCN monitoring at RSCC through Network Management System(NMS).

• Detecting faults, prioritising them and notifying to the contractor for immediate corrective actions.

• Follow up on corrective actions to verify that the agreed time frames aremet.

3



• Record all faults in the fault record sheet and summary of action taken for fault rectification.

• Co-ordinate all planned / breakdown site visits to minimize disturbance of service.

• Update status information of operated Network to users of POWERGRID

communication network.

3.0 MAINTENANCE

Maintenance activities are either Event Based (Fault/breakdown maintenance,) or planed site visits (Semi annual site visit, testing of channel/s if end equipment for data/speech does not communicate with corresponding equipment as and whenrequired) mainly carried out during working days.

Event based work is to be carried out round the clock seven days a week. Allfaults observed on the commencement of the contract shall have to be rectified

within seven (7) days of award of contract. A start status form (Annexure-II)shall be jointly filled by POWERGRID & contractor’s representative at 10.00 Hrsof commencement date of contract.

Planned site visits shall be carried out twice in a year (semi-annually) at all thesites in the network or time to time if speech/data is affected at a particular site.Thus, in a year, not less than two planned site visits to all locations will beundertaken.

Contractor will maintain record of events during the maintenance services;simultaneously POWERGRID shall also record the events in the LOG BOOK

available in the NMS control room.

The tasks during the planned site visits for the system include but are not limitedto following:

• Visual inspection of equipment• Alarm measurement verification• Status report of site• Updating of log records• Cleaning the equipment• Tightening of connectors• Sealing of antennas• Sealing of cabinets to arrest entry of rodents etc.• Measurement of earth resistance

Work to be taken up during semi-annual site visits are appended at Annexure-III

4



Fault/Breakdown maintenance is a process of fault correction / troubleshooting/interfacing with other contractor (for data & Speech connectivity of existing RTUs & EPABXs etc.) as per the fault reported by NMT. Contractor will maintain a log of activities carried out at all locations and necessary Historywill include site name, visit date, actions taken and site condition. Detailed report

in this respect shall be submitted by the contractor in the monthly meeting.

The representatives of POWERGRID will associate in trouble shooting, change of unit as per programme notified/intimated by the contractor however, due to anyreason if POWERGRID can not depute their representative, contractor will

proceed for the work so as to attend the breakdown/testing as per their programme.

The scope of corrective maintenance is as follows:

•

Troubleshooting on a network element and its interfaces as and whenrequired and directed by NMT engineer/coordinator of POWERGRID.• Diagnostics on interfaces to locate problems in network elements. If

required, the contractor shall depute maintenance engineer for jointinspection with other vendors for pin-pointing the fault.

• Identification of the faulty hardware unit, replacing it.• Performance of function verification in co-ordination with the NMT

operators.• Handing over of faulty unit to constituent/POWERGRID at site or RSCC.

3.1 Hardware Services

In case any failure or malfunction is discovered, the NMT shall immediately informthe problem to central coordinator of maintenance contractor. The maintenance teamshall identify the problem, organise to promptly attend the fault, replace the faultyequipment/card,/module or any other hardware component with a spare unit and shipthe faulty unit to RSCC or any other specified location. Each faulty unit shall bereturned with an accompanying, correctly filled-out Event Report. . Contractor shallensure maximum utilisation of the channel capacity, hence healthy channel/s will be

put in use and hardwired to respective MDF point without disturbing end user (PABX,PLCC,RTU ) connection so that outright replacement of card is avoided. Cardshall be replaced when all the healthy channels are faulty. Necessary modification

(temporary) in drawing/s in site copy and at RSCC will have to be done withoutchanging in original document.

POWERGRID is responsible to provide spares (Cards,modules,Feeder cable,Signalcable etc. ) to the extent of availability of spare with them. Spares does not includesmall hardware parts/accessories like BNC connectors, Coaxial cables, Euroconnectors, crone module, Cables including FO cable used for Inter/intra

6.0 Outage time definition:

An outage time refers to period in which loss of communication is detected onany part of the telecommunication network / equipment and continues until thefault is cleared .Following conditions shall not be taken into account for outagetime calculation.

(a) Time of unavailability excludes running with faulty equipment on specificinstructions from POWERGRID/constituents (not affecting communication or monitoring of other units other than faulty unit).

(b) The time of unavailability excludes the transportation time to a faulty siteaverage of twelve (12) hours and the time to get authorisation for access to thetelecommunication room and to the equipment.

(c) In case of failure of a E-1 channel, no consequential lower level channelfailure shall be accounted for.

(d) In case a loss of communication is detected in system of third party(PLCC/PABX equipment, RTU) and no corresponding alarm is detected in

NMS and it is decided by POWERGRID that the event will be jointly studiedwith the parties and plan /schedule of fault finding will be made. However,under such conditions of fault attribution to the third party, it would becontractor’s responsibility to logically establish such attribution.

(e) Outages which are not attributable to equipment faults (Fading etc.) will not be considered for calculation of system availability. Contractor shall calculatetotal outage due to fading / Power interruption on daily basis (10.00 Hrs of

previous day to 10.00Hrs of present day) and create a daily report.

(f) If it is needed to pinpoint a fault, it is allowed to disconnect / loop circuits for trouble shootings. This testing time shall not be counted in the outage timecalculations. However, interruption time for healthy channel should notexceed 10 minutes. Proper planning and coordination with all concerned may

be required while carrying out this activity so as to minimise outage time.

(h) Outage due to force majeure conditions (Not attending fault due to war,curfew, earthquake at the location of fault, serious accident during travelling

8



for attending fault) or outage due to failure in power system equipment (or AC/DC) ,non-availability of spare shall not be taken into availabilitycalculations.

7.0 Documentation during Maintenance Period:

Events shall be recorded by using of event form. The forms shall be filled in dulydated, timed and signed by representatives of both the parties. Absence of one or the other party’s representative shall not render the record invalid but assumesonly that such representative signs the record at his earliest convenience.The initial condition of the system shall be recorded on the start status form toconstitute or reference for later events. All the events recorded in the start statusform shall have to be rectified within 15 days. Faults not attended within 15 dayswill be considered as outage. Any and all events such as incoming and existingalarms, fault occurrence, action taken for remedies etc shall be recorded in theevent report forms. If a unit is replaced or repaired both the new and the replaced

or repaired unit is to be recorded in the event report form. Contractor shall submitthe detailed report for fault occurrence after the cards/equipment is rectified atthe works of supplier.

8.0 CALCULATION OF NETWORK AVAILABILITYIntroduction

This section describes the system availability calculation during theMaintenance period.

Availability Calculation Formula .

The system availability for FO & MW shall be calculated as follows.

T t*Ch t - ΣCh n*T n (n=1 to Cht )

S.A = --------------------------- x 100 %

T t*Ch t

WhereSA = System Availability (%)T t = Total test time (24*days in a month)Ch t = Total number of channelCh n = Number of channels affected by event EnTn = Outage time of event En

The NMS system availability for (FO & MW) shall be calculated as follows.

9



T t*NE t - ΣNE n*T n

n=1

(NMS) Av. = --------------------------- x 100%T t*NE t

WhereAv = NMS Availability (%)T t = Total test time (24*days in a month)

NE t = Total number of Network Element NE n = Number of NE affected by an eventTn = Outage time of NE

8.1 Availability Requirement

The availability of communication system shall be measured in categories as below:

(a) Channel (Voice, Asynchronous data & Synchronous data circuits andmanagement data channels)(b) E-1 level channels(c) Availability of NMS system

The availability requirement for type of channels, individually for MW, FO & NMS systems mentioned at Para 8.1 (a) ,(b) & (c) above shall be 99.9%.For calculation of availability main & Standby channel shall be treated as independentchannels.

However not-withstanding the commutation of availability of the

communication system as specified above, the prompt restoration of faultyequipment/part of the network is also of equal importance and any delay inrestoration of the faulty system shall be governed as per SCC clause no: 11.5.
