Boston, MA (August 29, 2008)--At this year's NAB Radio Show, APT will introduce voice transport capability on the WorldNet Oslo Audio Multiplexer, support for external synchronization of audio over IP streaming and support for SIP/SDP throughout the entire IP-based product range.
At NAB Radio, APT will unveil a new series of plug-in voice modules that have been developed for the WorldNet Oslo Audio Multiplexer, which offers a modular platform for the delivery of multiple channels of audio, voice and data over both IP and T1 networks. Now, broadcasters can combine both telephone and intercom traffic along with program audio and data for integrated networking over high-speed digital links.
The range includes a wideband voice module offering four independent, fully duplex 7.5 kHz channels as well as 4-wire E&M and 2-wire FXO and FXS modules for the creation of Off-Premise extensions and PBX links. Available audio modules include analog, AES/EBU, simplex, duplex and phase-matched options with support for both linear and compressed audio (Enhanced apt-X, MPEG L2, J.57 and J.41).
WorldNet Oslo now offers the option of adding an AES/EBU external synchronization input to the IP transport module. This enables the use of a common audio reference clock throughout all units on the IP network and ensures that the audio clock of all units is stable to achieve the highest audio quality possible over the entire network.
At NAB Radio, APT will announce support for SIP and SDP protocols throughout their IP-based product range to enable full interoperability with all compliant manufacturers' codecs. This development also enables the negotiation of traffic across firewalls and external networks and ensures that non-technical operators can establish connections quickly and easily.
APT will be exhibiting on Booth 618 at the NAB Radio Show, Austin, TX.
