An engaged employee is supposed to be conscious of the business situation, and work dynamics with contemporaries and peer groups to improve accomplishment within the job for the advantage and excellence of the company. It is a positive approach held by the employees towards the company and its values. Therefore there is a huge necessity for HR professionals to emphasize more attention not only on holding on to the existing workforce but also on having them actively occupied. The Employee Engagement Index is an online examination in which employees evaluate their own commitment at work. Most of the Agencies which provide Employment believe employee engagement to be one of the lead requisites to enhancing PES (Performance Evaluation System) performance. This presentation is an attempt to the acquaintance with the digitization of employee engagement by what is known as the Employee Engagement Index.

INTRODUCTION Network Signaling is done by signaling system no 7(ss7). It’s mainly used to mainly establish connection and tear down the connection between two end network elements. Connection between two entities here refer to call setup and tear down and it’s mostly used in public switched telephone network. The IETF define protocol suite named SIGTRAN that implements level 2, 3, 4 protocols compatible with ss7(pseudo ss7). This protocol has been developed to address the overloaded problem of ss7 due to 16 channel limitation in TDM. Using SIGTRAN protocol the PROTOCOL SIMULATOR tool can be inserted at every interface in the GSM architecture successfully, this would emulate the rest of the network without affecting the overall functionality. This Tool is used to learn specific about specific equipment in various scenarios. It’s mainly used for debugging the interfaces and check the interoperability between network elements. It is one of the easiest ways of learning the black box approach where the functionality of the equipment it totally neglected, the main focus being the input and especially the output. 1.1 SIGTRAN Its also called signaling Transport. It’s a telephony protocol suite used to transmit ss7 signals in the internet and handles calls using special commands. Packet switched connections are used to exchange to voice and other forms of information but earlier it uses circuit switched connection in PSTN. Calls over internet are transmitted as packets. It basically has 4 layers, lower layer is IP upon that we have SCTP, UA (User Adaption) set and the ss7 upper layer. SIGTRAN has 4 ss7 adaptation layers like M2UA (message transfer part layer 2 adaptation layer),message transfer part level 2 peer-to-peer(M2PA)message transfer part level 3 adaptation layer(M3UA) ,SCCP user adaptation layer(SUA). M2UA provide services of MTP2 in client server situation such as SG-MGC and the user will be MTP3. M2PA layer provides the services of MTP2 in peer-peer situation such as SG-SG. M3UA layer provides the services of MTP3 in a client server situation such as SG -MGC. The SCCP UA provides services of SCCP in a client server architecture, such as SG-IP. User would be TCAP or any application part. SCTP a new transport protocol designed or defined as a replacement for TCP by Sigtran. It’s manily used for time- sensitive signalling of data. TCP is not suitable for transporting real-time signalling data like TCP is byte-streamed, TCP timers defined in terms of seconds. ISUP protocol carries signalling messages for many PSTN resources. Suppose there are 3 calls then one of the calls experiences a loss of data which should not cause a delay in transmission of messages with another call. When a call is been established , the sender first transmits the ss7 signal to the switch which sends to signaling gateway and this converts signals to packets for transmiting over IP either to next switch or destination or other PSTN.
