✦ Synopsis
The Lucent Technologies 5ESS ® switch has been widely deployed to support voice over time division multiplexing (VoTDM) interfaces to service provider networks. Therefore, the integration of a new voice over packet (VoP) interface into the 5ESS switch architecture is both a complement and a natural extension to the VoTDM interfaces already supported by the 5ESS switch. A new 5ESS peripheral unit, the optical interface unit (OIU), is being developed to support a VoP and a VoTDM trunk interface on the 5ESS switch. The OIU will provide a highly reliable, cost-effective, compact, and energy-efficient solution for both VoP and VoTDM trunks on the 5ESS switch. The OIU will protect a service provider's investment in the 5ESS switch while allowing significant savings, both capital and operational, as the service provider migrates from circuit-based to packet-based voice services in their networks.
