TESTIMONIAL
“The Anue Simulator has proved itself in supporting our audio and video streaming test methodology based on introducing elements of signal corruption.”

Circuit Emulation Services
TDM Solutions in a Packet-Based World
New! Watch our CES Solutions video.
Despite the growth of Ethernet services, TDM still plays a significant role in enterprise networks in the 21st century. Circuit Emulation Services (CES) and Pseudowire Emulation (PWE) have emerged as methods for carrying TDM circuits over a packet-switched network. There are many benefits and applications for CES, all depending on the delivery of a low-delay, low-jitter signal over Ethernet.
Does your solution:
- Provide the optimum buffer size to compensate for the Packet Delay Variation found in Ethernet/MPLS networks without introducing unacceptable latency?
- Correct packet-sequence errors without affecting the user experience?
- Interpolate appropriate values for lost packets to minimize the impact on voice/video quality?
The benefits of transporting TDM over Ethernet are compelling. Both CapEx and OpEx required to support TDM services can be lowered, easing budget pressure for customers and enabling a sustainable business model for carriers to offer a full range of communications services. As a result, several organizations are establishing standards for this technology, including the IETF, the MEF, the MFA Forum and the ITU, to address encapsulation of Nx64, T1, E1, T3, E3, OC-3, STM-1, OC-12 and STM-4 lines for transmission across IP, MPLS and pure-Ethernet.
| Anue Network Emulators excel at circuit emulation testing by enabling you to emulate the packet network carrying CES with a high degree of precision and repeatability. |
Whether your application is backhaul for wireless transport, end-to-end TDM services for enterprise, or TDM access with interworking between Ethernet, Frame Relay and ATM, circuit emulation testing with Anue Systems can help you address the questions that must be answered before your circuit emulation or pseudowire solution is released on a live network.
With Anue Ethernet network emulation you can:
- Validate the performance of buffers by introducing Packet Delay Variation and re-order with great precision and repeatability
- .Validate the performance and accuracy of carrying critical timing information across a packet based network.
- Validate packet-loss-concealment algorithms by introducing packet loss and re-order with great precision and repeatability.
- Validate the performance of protection fail-over features.
- Verify compliance of performance metrics reporting and status/alarm indicators.
- Validate misconnection and malformed frame detection by modifying frame information. (MEF8)
- Improve time-to-market by increasing circuit emulation testing efficiency through Tcl automation.
- Develop and define new solutions by specifying performance metrics required for service levels and SLAs.
