Zarlink Semiconductor Inc. today announced that it has completed interoperability testing of its CESoP (circuit emulation services-over-packet) technology with BroadLight, a vendor of PON (passive optical network) products.
The combined technologies will allow service providers to deploy GPON (gigabit PON) fiber access networks that support “triple play” voice, video and data applications and T1/E1 voice, leased line and frame relay services.
According to Zarlink, as they migrate towards a unified network, GPON has emerged as the lower-cost, higher-bandwidth architecture of choice to deliver applications such as HDTV (high-definition TV), IPTV (Internet Protocol TV) and VoIP.
However, existing TDM voice and data traffic, which continue to represent a significant portion of carrier revenues, must still be cost-effectively transported over the new packet infrastructure, the companies said in a release.
The continued importance of TDM traffic is seen in the recent GPON RFP (request for proposal) issued inNorth America, which stipulates legacy services must be supported.
