Overview
Intraplex IP Link 100n, Single Bidirection Stereo IP STL Codec
A member of the award-winning Intraplex® IP Link audio codec family, the IP Link 100n is a powerful 1 rack unit AoIP model, designed to provide state-of-the art capabilities for remote contribution, studio-to-transmitter, and studio-to-studio applications at an affordable price.
With a full-duplex AES3, Analog, AES67 input and output along with 3 GigE network ports, the IP Link 100n packs full-featured IP audio codec capabilities into one standard rack unit. Interoperable with other IP Link codecs and Ascent, it is also compatible with industry-standard AoIP formats, including support of FM-MPX signal transport. With the support of payload privacy using built-in 128/256 key encryption via Secure Reliable Transport (SRT), the IP Link 100n is extremely secure and flexible. Stream splicing and automatic multi-source audio switching, including USB playlist as backup, further ensures reliability with constant and successful signal transport for your station.

In Depth
The IP Link 100n is a full-duplex, single stereo-channel codec for simultaneous reception and transmission of AoIP streams. The codec is designed to be compatible with the IP Link codec family and Ascent, including the IP Link MPXp codec for FM-MPX signal transport.The IP Link 100n is designed to provide an unprecedented level of full-featured reliability in an affordable form factor.At the streaming layer, the combination of SRT and Dynamic Stream Splicing (DSS) provides a set of networking tools for signal reliability even over challenging IP connections. The SRT transport protocol can simultaneously re-transmit lost packets in real-time while encrypting the full payload.
When using the traditional RTP transport format, the packet loss protection is provided using Forward Error Correction (FEC) and time diversity of packets. The optional Dynamic Stream Splicing (DSS) provides “hitless” protection against packet or link losses using diverse network paths for both SRT and RTP transport formats.
With full-duplex capability, the codec enables simultaneous operation of multiple transmit streams and receive streams for reliability. Using Multicoding capability, the transmit streams can be sent to multiple destinations with different formats and encoding. For instance, feeding multiple transmitter sites with different network bandwidths or feeding an Icecast server simultaneously, while sending an RTP or SRT streams to remote studio or transmitter locations.
In addition to the various built-in “hitless” packet loss protection techniques (e.g. FEC, re-transmission and DSS), the decoder also provides for three prioritized sources for switching. The source switching protects against failure of either an encoder or the main network connection. The codec lets the user define Primary, Secondary and Backup sources of streams or local USB audio.
