Base Station Protocol Test System Adds Wideband AMR

Adding another layer of versatility to the noted 6113 AIME base station protocol test system is support for wideband adaptive multi rate (AMR), a capability that affects the 3GPP TS45.003 test specification. The wideband AMR codecs, TCH/WFS12.65, TCH/WFS8.85, and TCH/WFS6.60, build on existing narrowband AMR technology and their introduction promises to significantly improve the quality of voice services. The 6113 AIME base station protocol tester allows users to create and test GSM base station software and hardware features by providing a mobile emulation. Combining its test set with the 6113E AIME software package, the system provides a layer 1, layer 2 and layer 3 monitoring and emulation capability for the Um interface. Software engineers can monitor, debug, and fault-find the layer 1 and protocol interchanges on the Um interface with fully decoded display of layer 2 and layer 3 messages. Other features include script editing, debugging, execution and automation facilities, and logging of all air interface signaling and traffic frames. AEROFLEX INC., Plainview, NY. (800) 835-2352.
