GL Announces Enhanced Wireless Analysis and Emulation Software

GL Communications Inc. announced today the release of enhanced Wireless Analysis and Emulation software – These tools are used for emulation and analysis of traffic at the A-bis interface (BTS to BSC links), and A-ter interface (BSC to MSC links) in the wireless network infrastructure. Speaking to the press, Mr. Karthik Ramalingam, development manager, said, “TRAU (Transcoder/Rate Adapter Unit) frames between the A-bis interface (BTS to BSC links), and A-ter interface (BSC to MSC links) perform the function of compression/decompression of speech channels within the radio cellular network. TRAU frames carry speech, data, and O&M information at full rate or half (8/16 kbps) rate and control information, over T1/E1 in a GSM network”. He added, “To reduce bandwidth requirements on the BTS-BSC and BSC-MSC interface, service providers use transcoders or voice compression technology - known as TRAU, or Transcoder/Rate Adapter Unit. TRAU frames between the BTS and BSC/MSC carry compressed spee
