Introduction
This report will be explained in two sections since for my first month I had been placed at the *** and then transferred to YYY due to reorganization of previous department. I do not have a role here instead I have to understand the management and technical operations for both departments.
SECTION 1
Main activities
What had been attain for a few weeks here is attending management as well as technical meetings to get overviews of what are the actual company’s mission and vision. The functions of *** is authorized to be responsible of Operation and Maintenance for all regions in KK which is ..............
What I had comprehended from those meetings is being summarized by weeks as shown below:-
Week 1:
1) Meeting with consultant regarding the outsourcing of restoration for local access services together with docket LL(broadband).Basically it is just altering some figures and statements in the paperwork regarding to the performance of the consultants presentation to the top management of TT.
2) Meeting with TT corporate sales and with other task force which is about setting an IP connection and secured network system for five banks which are ............
3) Meeting concerning on the budget release for implementation of LL International ISP network infrastructure enhancement projects which includes the procurement of router interface cards for connecting ISP, TT Retail International links (IPLC).This network is to ensure adequate network infrastructure to cater for additional international bandwidth capacity for TT so that high quality service will be given for customer satisfaction.
Week 2:
1) Meeting regarding the leasing staff report in which problems arises when what is manually reported is not the same as being reported in the system. For broadband report on the other hand, basically it discusses about the problem areas in which the signal cannot be reach. A good transmission of Broadband network require Signal To Noise Ratio (SNR) less than 12dB including the area must covers radius of less than 4km.Accordingly, if it is less than that, area which the signal covers maybe encounter disconnection of network for three or four times a week which transpire poor network condition. Another problem of disconnection is due to poor quality of the copper wire being used. The solution is, TT will caters at the areas which the signals theoretically can be reach instead of areas outside the 4km radius due to the tight budget.
2) Meeting is about the survival of outsourcing contractor in which the issue arises because of the small budget allocation. The solution is to merge some of the contractors and also varies the material being supplied.
3) Meeting with all regional’s general manager about a few problems in their operation which are:-
i. ADSL (Asymmetric Digital Subscriber Line) did not achieve the required performance due to human error and also remote station location. It is because ADSL can only be used over short distances which less than 5km.Once the signal reaches the telephone, the ADSL stripped off immediately routed onto a conventional internet network while any voice frequency signal is switched into the conventional phone network
ii. This issue is about TT JJ project which stands for Network Inventory System which functioned to manage TT’s network infrastructure at physical and logical levels. Thus, it will have a single database and real time view of all network resources which includes equipments, facilities and circuits. It also can help to manage; plan and provision physical and logical infra for multivendor, technology, layer network elements and cross domain models.
iii. Cable theft which informing the solutions which is alarms system called CC and VV.
iv. Adaptor of DEL installation MN1 which have no protection since the earthing is not properly designed. Consequently, some accident occurs due to lightning which brings an excessive voltage and damaged the phone as well as human if it is in used. The new version of adaptor which call as MN2 have the protection but the problem is the design is not practical and it caused increase of budget if redesign is performed.
v. About RSD IP VPN project deliverable. An IP Virtual Private Network (IP VPN) can be defined as the collection of switching and transmission resources that will be used by a dedicated set of authorized users to exchange information over a shared IP infrastructure, hereafter called "the network". It is a secured network of end-to-end services with any device connectivity which cover global roaming, independent access, easy configuration with tunnel option, network implemented user features and online user management.
Week 3:
4) Meeting is about the upgrading of CDMA BTS from 95B to 1x in which it requires new CPE of 800MHz.Some of the migration issues is that, the new BTS which has already being installed caused problem of received signal for the CDMA customer. This is due to overlapping or interference from nearest BTS with the new installed one.
5) Meeting with all contractors about a few problems in completing their task while also reach the performance target by TT.
Week 4:
6) Meeting is about the Occupational Safety and Health Implementation which has the objective to preserve staff working on site.
7) Meeting is about rehabilitation of maintenance in which it has been made due to aging and degrading of the quality of copper wire. This program is made to reduce the trouble report but the issues here is it is not decreasing as expected due to existence of other factors.
SECTION 2
Main activities
So far, what had been done for a few weeks here is attending technical meetings to get overviews of what are the actual operation of the department and also analyze and understand the CDMA and BFWA alarm monitoring system. YY responsible for providing centralized technical support and coordination for the operational of Wireless System nationwide of CDMA: Fixed Wireless using 800MHz and also BFWA: Broadband Fixed Wireless Access. Besides, YY is responsible in satisfying customer requirements of service availability, integrity, reliability and quality. The structure of YY consists of three departments which is ..............
Meetings which I have attended are:-
Week 5:
8) Meeting is about one of Tt’s vendor (***) of the optimization of CDMA network. The need of the optimization arises due to the purpose of initial RF network optimization to ensure each cluster is integrated into overall network and prepare the CDMA system for commercial service. Some of the factors that contribute to optimization are due to increasing number of subscriber, change of type of service and implementation way and also geographical changes. By optimization, the capacity and coverage will balanced, ensures better QoS of voice quality, fewer dropped call, better data rates and less blocking. What being optimized here are the CDMA pilot power, neighbor cost, search window, cell radius, some physical orientation and tilting and pilot pollution. Pilot pollution means too many interference in more than four BTS in one area covered in which resulting handoffs and overlapping of signal. Hence, *** had introduced software called TEL which provides advance optimization capabilities by plotting Call Data Locks (CDL) data by location of its attributes.
9) Meeting is also about optimization but for this vendor (NT), they provides consultancy for network audit. This consultancy is vital since poor network resulting a shrinking of revenue. For that reason, TT needs this consultancy for the benefit of increasing the network traffic capacity, QoS and also better service coverage so that customer satisfactions will be fulfilled.
