Press Release: GL Announces Powerfull Packet Test Tools - PacketScan™ and RTP Toolbox™

Gaithersburg, Maryland, USA - November 2'nd, 2006 - GL Communications Inc., announced today the release of enhanced packet test tools PacketScan™ version 2.0.32 and RTP Toolbox™ version 1.33 with Voiceband Codecs. Briefing to the media, the significance of voiceband codecs and how they differ in voice quality, Mr. Jagdish Vadalia, Senior Manager of Product Development at GL said, "The word "codec" is a compression of the two words "coder decoder" and is used to identify a voice compression algorithm. Telecom Engineers are always looking to transmit or store voice in the least bandwidth or space - thus the need for more sophisticated codecs". Applications include:

  • Wireless networks where efficient use of scarce frequency spectrum is important
  • VoIP networks where packetized and compressed voice is used to transmit over the World Wide Web
  • PCs, MP3 players, and mobile phones where codecs are used to transmit, store, and play voice and music"

Mr. Vadalia added, "GL's packet test tools: PacketScan™ and RTPToolBoxTM are now supported with both narrowband as well as wideband codecs that help in transmission or storing voice in the least bandwidth or space"
