Zarlink Semiconductor Inc. has developed Timing-over-packet (ToP) technology that allows carriers to support time-critical voice, video and data services over packet networks.

According to the Ottawa-based company, carriers rolling out packet-based equipment face a major stumbling block because many services including video, online gaming and cellular phone services have critical time dependencies that cannot be met by "best-effort" packet infrastructures.

As a result, they must rely on expensive solutions such as GPS (global positioning system) receivers and circuit-based T1/E1 connections to ensure accurate synchronization of services across packet networks.

Zarlink’s patent-pending ToP technology enables timing and synchronization to be distributed across asynchronous Ethernet, IP and MPLS packet networks.

Carriers can lower their operating costs by replacing GPS receivers and T1/E1 connections, while ensuring high-quality service for time-sensitive applications, the company said.
