An IMS Network Decreases Power Usage and Improves Efficiencies


The days of time-division multiplexing (TDM) managing the majority of our phone calls is coming to an end. The soon-to-be obsolete switches have too many issues, and offer limited opportunities to expand.

Conservation: TDM switches require constant bandwidth per channel, emit a whopping 1.7 billion kg of CO2 each year in the U.S., which is equivalent to 361,000 cars being driven for a year (1).

Operating expenses (OPEX): Power usage of TDM switches account for 2-3 percent of a network’s total OPEX (2).

Adapting to new user behavior: Phone service with voicemail doesn’t cut it anymore. Data networks and voice networks are enmeshed in one giant network that allows people to simultaneous download, chat, video conference and engage in a variety of online social activities.

Offering a far more efficient and next-gen solution is the IP Multimedia Subsystem (IMS) architectural framework, which unifies fixed and cellular switching. Alcatel-Lucent offers its own IMS End-to-End Solution, which offers the following benefits:

  • Total communications – from simple voice-over-IP (VoIP) to enhanced multimedia communications.
  • One IMS switch can replace multiple TDM switches. Reduce OPEX with fewer offices to manage.
  • IMS equipment can scale from a few users to thousands.
  • Low-energy scalable switches emit less heat, reducing expenses in energy consumption and cooling.

To learn how Alcatel’s new communications architecture reduced footprints by 75 percent and power use by 65 percent, make sure to read “Alcatel-Lucent IP Multimedia Subsystem: Eco-efficiency Makes Economic Sense.” Then learn how those savings can apply to your enterprise by checking out Alcatel-Lucent Data Network Solutions by business type.
