Optus, OPTUS (Australia), September 2021 - September 2023, Fault Management Engineer, 10, NSM, Graphana, Niometrics, Openet, IRIS, Secure CRT, DNA tool, Optus is the second-largest wireless carrier in Australia, with 10.5 million subscribers as of 2019. The company trades under the Optus brand, while maintaining several wholly owned subsidiaries, such as Uecomm in the network services market and Alphawest in the ICT services sector. To provide services, Optus mostly owns and operates its own network infrastructure, It provides services both directly to end users and also acts as a wholesaler to other service providers such as Exetel and Amaysim. Through its Optus 'Yes' brand, it provides broadband, and wireless internet services. Other wholesale services include Satellite and 4G Mobile. Optus provides services with voice, wireless, Internet access and television. The wireless carries (GSM, 3G/HSPA, 4G/LTE, 5G) Deal with monitoring tools like network packet capture tools like Wire-shark, SecureCRT, Whatsapp GOLD, Telnet, Hyper Terminal, Microsoft Visio, BMC Remedy, Citrix, DNA (EPG traffic onload offload and all node Healthcheck) etc. EPG Ericsson SSR 8020(16B CP04), MME Ericsson( MKVIII 1.19), Graphana, NSM, PCRF (Openet), Niometric, WMG (Ericsson SSR), DMG (F5), DSR(Oracle). Mitel, MITEL, September 2015 - December 2015, Fault Management Engineer, 5, Mitel’s Packet Data Network Gateway (PGW) is 3GPP compliant Evolved Packet Core (EPC) network element, which anchors network mobility while functioning as the termination point of the packet data network interface towards internal and external Packet Data Networks (PDNs). Mitel’s EPC has been deployed widely as globally operators transform towards 4G LTE networks. Current EPC deployments are primarily targeted towards initial 4G LTE devices geared for mobile internet traffic. With its proven leadership in VoLTE and RCS, Mitel brings in a unique perspective of utilizing EPC for telecom communication driven services such as user-to-user voice, video, messaging, content sharing etc. To solve the specific challenges of packet latency, QoS on the backhaul and IP peering tied to real-time IP based communication services, Mitel’s PGW is specifically architected to provide key PGW functions of resource allocation/usage policy enforcement and packet routing/forwarding/charging/filtering at a very optimized Packets Per Second (PPS) processing to enable cost-effective and efficient deployment of next-generation communication services. At its core, Mitel’s virtualized standards-based solution for PGW provides connectivity to external Packet Data Networks such as the internet/Intranet, and IMS (enabling services such as VoLTE and RCS). The PGW interoperates with both 3GPP (2G, 3G, LTE) and non-3GPP (i.e., Wi-Fi) access networks, offering seamless mobility. It assigns IP address to the UE and handles packet routing, filtering and forwarding functions. CISCO SCE 10K, CISCO, January 2014 - January 2015, Test Engineer, 5, Windows XP, Linux, Secure CRT, IXIA, The Cisco Service Control Engine is specifically designed for carrier-grade deployments, requiring high capacity, stateful application and session-based classification. It helps to control or manage application-level IP-traffic by subscriber. It is designed to deliver exceptional performance at heavy load condition. It analyses, charge for and control IP network traffic at multi-gigabit wireline speed. It reports and analyze network traffic at subscriber and aggregate level for capacity planning. It provides different service levels for different customers, contents or application. It identifies the network abusers who are violating the acceptable use policy. It altogether does network management, subscriber’s management and service configuration management. IMSCore Testing (IMS-1000), Sensaphone, USA, December 2012 - October 2013, Test Engineer, 8, Windows XP, Linux, SIPp, Ethereal, IMS communicator and OpenIMSCore, SIP, SDP, TCP/IP, UDP, The IP Multimedia Subsystem, IMS, IMS-1000 is an architectural framework, originally designed by the wireless standards body 3GPP for delivering IP multimedia services to end users. The IP Multimedia Core Network Subsystem (IMS-1000) is a collection of different functions, linked by standardized interfaces, which grouped form one IMS administrative network. So, in Gm interface two node exits that is UE and PCSCF. The Test case is divided into two parts, one for testing the UE and another one for testing PCSCF. SIPp provides an integrated environment to test telecommunication software and hardware. It provides a programmable testing platform for telecom system developers and service providers. In case of UE testing the SIPp simulate both PCSCF and Other Core entities and in case of PCSCF testing SIPp simulate the UE. To verify the test case, we use the OpenIMSCore for PCSCF, ICSCF, SCSCF and HSS. In case of UE testing we use the IMS-communicator. Aradial-softSwitch, Aradial, USA, December 2011 - November 2012, Test Engineer, 8, Windows 2000/XP, Linux, SIPp, Ethereal, X-lite, 3CX, IP phone (Thomson), SIP, SDP, TCP/IP, UDP, RTP, The Aradial-SoftSwitch is communicating with VoIP network to PSTN network. This to submit herewith for a SIP & SS7 enabled multimedia solution providing for a set of Telephony services for voice & video communications over IP based broadband networks. SIP to PSTN provide a framework for the integration of legacy telephony signaling into SIP messages. SIP multimedia solution for Next Generation Networks providing as such the basic for future expansions with NGN elements and multimedia applications. SS7 ISUP, SCCP messages are encapsulated within SIP in order that information necessary for services is not discarded in the SIP request also when interfacing with a SIP Proxy/Redirection Server the SIP messages are translated to ISUP and vice versa. The aim of these solutions is to bring the fixed services operator into the VoIP value chain by providing the opportunity to deliver innovative multimedia communication between residential customers. Having test through SIPp tool and ethereal. IP PHONE (2000), Wipro Own project, January 2011 - December 2011, Test Engineer, 7, Windows 2000/XP, Linux, SIPp, Ethereal, IP Phone, SIP, SDP, TCP/IP, UDP, ASE is an application server that communicates in SIP (Session Initiation Protocol) and is widely used for the advance telephone services in IP based enterprise network. ASE unifies voice, video and data over a single packet network and is fully compliant with SIP RFC 3261.The application server performs the role of SIP Registrar, Proxy server, Redirect server and Location Server and works in conjunction with SIP enabled IP PHONES, Announcement Server, Conference Server, Media Server etc. Also, the ASE supports various features like: Call hold-retrieve, Consultation hold, music on hold, call forwarding.
