Codec audio modules
Previously available only for IP audio transport, the Oslo 1U now offers greater flexibility in configuration and can be deployed in many different networks. Based on a modular architecture with four available slots, the unit can accommodate up to three audio cards when fitted with a new T1/E1 module. Each of these audio cards supports four channels of audio in simplex, duplex, analog or digital format and the configuration is fully software-selectable with no hardware switching required. Alternatively, when deployed for audio over IP transport, the unit can support up to 16 channels of audio across four AoIP modules. Each of these modules combines audio, IP transport, management and auxiliary data -- the complete functionality of a codec unit - onto the single, plug-in module.
