As with previous upgrades and additions to the SymNet toolkit, Acoustic Echo Cancelling is offered as a series of software modules that can be added to a SymNet design at any time based on the system application. Included modules perform at three different bandwidths for use in telephone conferencing, video conferencing, and wideband conferencing within a building or over a fibre connection.
SymNet's open architecture allows system designers enormous flexibility when implementing Acoustic Echo Cancelling, especially when compared to some competitive systems. Since the module is not directly tied to either a hardware or expansion card input, its audio and reference inputs can be derived in a number of different ways, and changed on demand to suit different room configurations or alternate conferencing hardware.
SymNet's control capabilities have been further enhanced in this release with the addition of a Control String Output module. This allows SymNet to issue serial string commands to outboard devices over RS-232. This simple control module has allows system designers to embed a command string of up to 63-character in ASCII or Hex format. The command is then issued from the SymNet device over the RS-232 communication port.
"The addition of these two features makes this a powerful upgrade for the SymNet platform" stated Dan Gallagher, Symetrix executive vice-president of global sales and marketing. "It makes SymNet a viable choice in the contemporary boardroom market where conferencing technology is a requirement."
"This version of SymNet Designer is about adding new capabilities, while making our product easier and more accessible than ever before," Gallagher adds. "It opens new doors for us and simplifies the design process for new users and those familiar with our system."
