Corrective Maintenance Goals
The goal of the corrective Maintenance is to identify, evaluate, fix and report any fault(s) that may appear on Client sites as per industry standards in minimum time. Client evaluates the performance of the Damcon based on mean time to restore (MTTR) calculated for that site on per event basis and averaged on monthly. Damcon tries to restore any fault before the targeted value of restoration time assigned as per the priority of that site.
Project KPI system
The Damcon identifies and resolves fault under his assigned scope (FLM/SLM), during such work keeps Client field operations/NOC staff updated, at completion the Damcon presents a comprehensive root cause analysis along with steps taken to solve the fault (for future references).
Since spare management is in scope of the Damcon therefore collection from Client warehouse, transportation to fault location, use and return (if not used/faulty part) to Client designated warehouse shall be under responsibility of the Damcon. All related costs is borne by the Damcon. Spare parts for BTS, Transmission & Rectifier are identified by the Damcon before start of each quarter.
Spares are provided by Client, housed by the Damcon for Telco and non-Telco equipment.
All tools are purchased by the Damcon at its own expense. Consumables are provided by the Client to Damcon. Damcon is responsible to collect consumables from Client warehouse. Transportation of the consumable is prime responsibility of Damcon. All the consumed consumables and faulty/non repairable parts are returned to Client warehouse. Such transportation is without any additional cost to Client. Faulty parts that will go for R&R shall be returned back to Client on weekly basis whereas consumables and non-repairable parts of Non Telco can be returned monthly. Damcon keeps the consumption report record with itself and shares with Client on monthly basis. Faulty replaced batteries are returned to warehouse within seven calendar days.
Once consumable changed on site must be labeled with site ID and date of changing clearly mention on consumable (oil filter, fuel filter and air filter).
Client reserves the right to inspect/audit the sites where consumables/parts are changed, Consumables/parts are properly labeled with bar code and Damcon is not allowed to scratch or damage the bar code, Client has all right to audit the site for verification of proper consumable/part changed or not.
Reverse Transportation of spares is done to only Client designated warehouse. Any other facility cannot be used to store Client spares. Any Telco or Non Telco asset cannot be moved for a BTS site until Client’s management approval.
For Fiber Optic Cables repair, Damcon ensures that repair service is available in all regions and MTTR is as per SLA.
Activities that shall be carried out upon the occurrence of an event implying a set of interventions which have to be planned out of a recovery process with SLA assessment:
Replacement of BTS Cabinet different cards.
Transportation of Batteries/Power cables and RF antennas from warehouse to site or site to site.
New Alarm patching as per Unit Price List
Link alignment/panning
BLVD by pass activity
Cables Routing/lay with plan outages
Activities that shall be carried out upon the occurrence of an event implying a set of interventions which have to be planned out of a recovery process without SLA assessment:
Inspection the following items semiyearly:
TRX/RRU/BBU replacement such that if site is in Damcon scope and TRX/RRU/BBU is faulty and not available in warehouse, Damcon team shall collect functional TRX/RRU/BBU from one site and replace the faulty.
TRX/RRU/BBU at the other site with the functional TRX/RRU/BBU. However, Damcon will limit such additional visits to a maximum of 90 visits per month.
Up to 10 visits of sites for Radio modules addition per month would be carried out by DAMCON. This activity excludes antenna and feeder cables extension. In case more such activity is required, Client shall prior intimate Damcon for such activity.
Up to 15 E1 patching per month required by Client.
