Zarlink Semiconductor today launched its ZL50111 family of packet processors for delivering high-capacity TDM-to-IP/Ethernet interworking.

According to the company, the devices are the only packet processors capable of sending high volumes of TDM traffic – up to 32 T1/E1 streams – over IP/Ethernet networks with the same voice quality and service flexibility as conventional, TDM-based telephone networks.

“To handle the rising volumes of IP data traffic, service providers are stepping up investments in metro Ethernet packet networks, which commonly feature high-speed IP/Ethernet links to customer sites,” the company said. “As a result, demand is growing for a new class of network edge equipment with TDM-to-IP/Ethernet conversion capabilities, or CESoP. This equipment lowers costs by allowing less expensive Ethernet networks to carry high quality, profitable TDM services, such as T1/E1 leased lines.

“A key challenge in delivering CESoP is achieving the precise levels of network synchronization and clocking required to reliably deliver constant bit- rate voice traffic over variable bit-rate packet networks.”

The packet processors consists of three chips that allow equipment manufacturers to cost-effectively support a wide range of TDM traffic densities and data rates.
