NOTEABLE MILESTONE FOR CORPORATE SERVICE MANAGEMENT IN 2008

A.COMPLETION OF Q1, Q2, Q3 and Q4 (excl Metro-E) OF NETEXPERT MONITORING FOR CORPORATE CUSTOMERS BY THE END OF 2008. This allows for PROACTIVE monitoring and ALARMS escalation for Corporate Customer Circuits. After re-organisation in April, NMC is taking the lead in the integration of Metro-E into Netexpert while TSTM FIXED VSAT having the role of supporting them

Proactive Monitoring Readiness For Corporate Customers

FIXING FIXED NETWORK HOT ISSUES 2009

A. SIMUX NODE LOST OF CONFIGURATION DURING POWER RESTART

Issue: Frequent DIMM failure which leads to loss of configuration after power restart Impact: Simux nodes down affecting Corporate Customer Leased Circuit Solution: To upgrade to latest DIMM hardware which can secure configurationAction: 1) Request PSE counterparts in implementing this solution to the top three non-TOC sites/nodes as below; i.e sites MAY110, PBB321 and SIT360 costing around RM70k (Finance approved; in process of hardware acquisitoin). 2) Improve the battery backup performance especially for NON-TOC sites (networkwide initiatives)3) Limiting downtime period by setting a regular auto config backup in Simux Element Manager; i.e. Mainstreet (Still under study) for easy re-configuration during configuration lost eventThe latest occurrence at SITA Bandar Sri Damansara on 8th. June 2009 where the whole circuit from a particular nodes of Simux were migrated to its adjacent nodesFixing Fixed Network Hot Issues 2009

B. FREQUENT HARDWARE FAILURES (SELECTED MODULES) FOR MSAN/ANYMEDIAProblem: Frequent hardware failures for Comdac card, LPA833 and Tyco rectifier for MSANImpact: MSAN nodes failure; shortage of spares Solution: Having analysed MTBF LPA833 is to be send to ALU R&D. Comdac card root analysis by ALU R&D pin pointed to their corrupted Flash card (certain batches)Action: Comdac: Due to significant reduction in Comdac failures since May and risk analysis, swapping this related batch of cards are being put on hold (under monitoring). LPA833: still awaiting ALU feedback and for BOTH Comdac and LPA833, aggressive beefing up of spares are going on hand in hand via improved R&R MTATRectifiers: Effort are being made to beef up spare stocks Field Ops: Taking advantage of the recent re-org in improving the coordination in logistical practise of sending out items for repair (end-to-end)

CONTINUOUS IMPROVEMENT

DESIGN/PROCESS REVIEW

Several notable projects like Astro MCS and Bank Islam are under review by TSTM in order to ensure that SLAs are met. Besides that TSTM Fixed VSAT works hand-in-hand with PSE for architecture/product change; e.g. MSAN via Metro-e (discarding ATM) and ONU replacement with MSAN

CONTRACT REVIEW

EWP for both vendor and outsourced contractors are being reviewed to ensure maximum values are being delivered to Maxis. Example of this is establishment of monthly operational meeting with ALU and inclusion of the Fixed Network section in the NSN review meeting

DATABASE MAPPING

Inaccuracy of customer circuit data between the HPS database and physical connections are site are becoming inherent problem to the Field staffs. There is a pressing need for NCM to lead in this rectification processes while TSTM playing its supporting roles

ORGANISED PM EFFORT and MTBF BENCHMARKING FOR PROBLEMATIC MODULES

An improved strategy for effective PM efforts are being established. In some technology areas like Metro-e, Simux, VSAT this have been fully established and currently on-going. Revision on effectiveness of VSAT PM (with the MTBF review of parts) will be done together with the MSAN PM reviewContinuous Improvement Aspects

Continuous Improvement Aspects ContdENHANCING COMPETENCIES

From time to time staffs will be enrolled to courses that enhance their competencies. These include any competence analysis on the current workforce as can be seen in the Metro-E support readiness analysis below:

CONCLUSIONS..

There are not so obvious competency gap between TSTM_Fixed_VSAT and RANO as far as Metro-E formal trainings are of concern (based on the training matrix on the previous slide). However, some gaps are expected between personnel in the two Sections under Field Operations based on the amount of knowledge transferred by vendor (HP) and specialisation of work

In order to address this TSTM_Fixed_VSAT plans to hold a hands-on session in a few weeks time. The proposed contents of this session is as per attached below
