Integrate the operational requirements for new technologies and services that will be supported by Network Operations and as per Marketing Requirements. National and international data changes- RSA Network and Africa. CP & APG slides – testing and integration. IR21 changes for signalling, NDC’s and numbering plan changes• 3rd Party Implementation - Implement/test and maintain routing to third parties i.e. VC/CELLC/IVR/SENTEC/TELKOM/Call Centers/Vans/Premium Rated/Banks/BRS –Marketing Requirements etc. Ensure that all technical requirements are met to introduce roaming with new Roaming Partners. • Expansions - Ensure that hardware capacity exists for future projects and expansion. National switching equipment remodelling/redefinition. Ensure that switch capacities are monitored and expansion of links and C7s / AXE equipment / Processor Upgrades is put in place and executed. Liase with System Planning regarding HW requirements. Specify, source and deploy O&M tools/systems to ensure optimal functioning of the international roaming services. • Support - Implement new software / ACA levels as and when released by E///.Assist with the operational and integration of new MTN networks internationally. Assist Regional maintenance, SMC, VAS, Pre-Paid, CS, System Planning, Network Testing and Ericsson support staff where required. Ensure accurate completion of all CSR’s.Assist in the development of an automated and effective environment. Be a subject matter expert on International Roaming issues by studying global trends and networking with other professionals in this field, and by providing documented recommendations to various MTN departments. Do fault finding and trouble shooting by confirming data integrity on SGSN’s, BGP’s and GPRSDNS. Escalate unresolved faults to 3rd tier, foreign operators, GRX Carrier, etc. • Routing - Implement and standardized B-number analysis table. This includes Pre-analysis, the allocation of BNT values, the routing, the allocation of special numbers, Global title routing, NDC. Maintaining core routing.
