IQOYA *LINK is a stereo IP audio codec specially designed for STL and SSL applications based on IP networks. It has been developed in close collaboration with leading European Telcos around the following themes: full IP connectivity, reliability, IP streaming robustness on managed and unmanaged networks, continuity of audio service on transmitter sites, full remote control and monitoring from SNMP supervisors. IQOYA *LINK is based on a low consumption, fanless, and robust dedicated hardware platform. It includes a rich set of features allowing for the reliable transport of audio content over managed and unmanaged networks (FECs, redundant dual streaming with time diversity, VLANs, QoS, IGMP), and for continuity of audio service on transmitter sites (3 backup levels, backup on SD card, switchable hardware by-pass of audio inputs to outputs in case of power supply failure). It can be used in analog and AES/EBU environments, as well as Livewire, RAVENNA and AES67 environments. In addition, IQOYA *LINK can be fully controlled and monitored through SNMP.
- Full-duplex stereo IP audio codec
- Low consumption and fanless platform adapted to transmitter sites (strong resilience to EMI)
- Two 10/100 Mbits/s Ethernet ports for separate control traffic and IP audio streaming, or for seamless stream failover (dual redundant streaming), or for a fail-over on a secondary network
- Balanced analog and AES/EBU inputs/outputs
- Support for Livewire (standard mode), AES67(*), RAVENNA(*) inputs and outputs (*:excluding simultaneous encoding/decoding in AAC, aptX, or Opus, with AES67/RAVENNA I/Os)
- Audio formats: PCM, G711, G722, Opus, MPEG L2 & L3, Fraünhofer AAC-LC, AAC-LD, AAC_ELD, HE-AACv1, HE-AACv2, and optional Qualcom aptX™
