Ultra-Fast Broadband the Path to End-to-End IP Telephony and PSTN Migration

By Mae Kowalke, TMCnet Contributor

The TDM-based public switched telephone network (PSTN) still brings in revenue, but operators need to start thinking about PSTN transformation as vendors start to move away from TDM equipment support and existing revenue from the PSTN network dries up.

Adding fuel to the need for PSTN transformation is the increasing cost of maintaining the PSTN network.

The direction of the PSTN migration is clear.  Operators need to move to an IP-based network. This has been an inevitable and desirable trend for many years. In addition, it presents the opportunity for operators to converge their voice and data services onto a single network architecture that can drive revenue and cost reductions.

MPLS-Based Networks Keep Public Safety Communications Humming

By Mae Kowalke, TMCnet Contributor

When it comes to first responder communications, network quality matters a lot. Public safety organizations need reliable, secure communications networks.

Traditionally, public safety networks have used plesiochronous digital hierarchy (PDH), synchronous digital hierarchy (SDH) or synchronous optical network (SONET) TDM technologies for their networks. But as communications have evolved, TDM is proving insufficient for IP-based voice, video and data systems.

“Many public safety communications networks are evolving to broadband solutions which utilize an IP WAN for first responder radio networks, video surveillance, LTE, improved interoperability, and better integration with growing IT applications, noted a recent white paper on the topic by Alcatel-Lucent, "Mission-Critical Communications Networks for Public Safety."
