As the Indian enterprise community is getting increasingly technology savvy when it comes to putting in place cutting edge communications infrastructure, the government agencies are not far behind other enterprise segments.

Even with the ongoing deployment of IP networks in government agencies and departments, there are still a large number of circuit-based applications in governments.

And with the circuit-based applications like TDM leased line and voice based Private Branch Exchange (PBX) connections, serial encryption connections and others it is becoming increasingly important for the government stakeholders to understand the requirements for successfully transporting these applications across next-generation IP networks and hence it is getting popular within the government side of enterprise segment within India.

In telecommunications and computer networks, multiplexing is a term used to refer to a process where multiple digital data streams are combined into one signal. The objective is to share an expensive transmission resource. The multiplexing divides the high-level communication channel capacity into several low-level logical channels, one for each data stream to be transferred.

Different government organizations around the globe including India, still utilize various types of proprietary TDM multiplexers to help aggregate voice and data applications across higher speed connections. There are a number of specific situations where these lower speed connections occur include communications with tactical military groups around the globe over satellite connections to emergency communication networks for community quick response teams.

However, some negative attributes of these older and aging TDM multiplexers are - lack of interoperability within different standards due to the vendor-specific proprietary technology and they are also unable to scale to large world-wide implementations due to density and processing restrictions.

On the other hand, a large portion of the installed base of proprietary TDM multiplexers are nearing the end of their product life cycle, there is still a large number of systems in use supported by large quantities of spares within depots, so we can expect these networks to be sustained well into the future in many government agencies and departments. Moving forward, government agencies are likely to go with next-gen IP networking protocols and make the most of their existing communications infrastructure.
