ANT-5 3G
Video/music and always-on connections are by-products of 3G networks. Wireless networks delivering broadcast entertainment and downloading music and streaming video must support data speeds expected to reach above 3 Mbps. As more service providers adopt 3G, increasing the capacity of the link between the base station (node B) and the ATM switch or network connection becomes critical. In addition, the strength of the signal must be maintained at even greater distances from the base station. 
When commissioning node B, the full network connection and its performance along with communications between the radio network controller and node B must be checked and validated. In addition, critical components of network maintenance include managing the performance of all channels and finding faults quickly. Both stages require routine checks of all ATM channels to confirm they are operating fully as well as measuring delays, data loss, and priority levels to validate service agreements specifications are being met.
JDSU introduced the ANT-5 3G testers to cost effectively install, commission, and maintain the wireline systems used to support ATM 3G (UMTS) mobile networks.
With the ANT-5 3G, service providers can perform the following:
Because voice/video traffic runs on AAL-2 and data on AAL-5, it is important to test the robustness of these channels by generating and analyzing voice and data services. The ANT-5 enables the system to be stressed to confirm that AAL2 can maintain time-critical traffic, such as voice and video, which have a higher sensitivity to data loss. It also can be configured to test the key channel priority parameters assigned by both AAL2 and AAL5.
The ANT-5 3G offers an extended channel explorer, which displays a lot more information on each VCI/VPI, enabling real-time analysis.
Another key function of the ANT-5 3G is its ability to generate ATM traffic that stresses the system and then perform detailed analysis to see how the system responds, such as does it discard the correct channels.
Inverse multiplexing for ATM (IMA) transmits a data stream that is greater than 2 M on a set of parallel 2 M links. This avoids having to rent/buy/install an STM1 connection or delay deploying one until the volume of traffic justifies the expense. The ANT-5 3G measures 1 cell every 100 ms and refreshes the display every 1 second, enabling service providers to determine the reason a link may not have enough bandwidth.
