Telos Infinity Link is an OPUS codec-based software product launched as a part of the Telos Infinity solution at NAB 2019. The product takes the form of a series of software licenses that can be added to any host Infinity Panel or Beltpack hardware, unlocking 2 (Beltpack only), 4 or 8 embedded codecs which convert WAN-side VoIP to LAN-side LW+ AES67. There is also a 1ru hardware Gateway device supplied with dual AC power and dual gigabit Ethernet connection supporting either 8 or 16 embedded codecs.

The OPUS codec is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet but is also intended for storage and streaming applications. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype’s SILK codec and Xiph.Org’s CELT codec.

The Product

Link for Beltpack: INF-BP-2/Link2 supports two bi-directional codecs running on a standard Infinity wired BP.

Link for Panel: INF-MP/DS-16 and INF-MXP-20/Link4 and Link8 supports four or eight bi-directional codecs running on standard Infinity Panels (Master, Desktop and Expansion).

Link Gateway: INF-Link Gateway-8/16 supports either 8 or 16 bi-directional codecs running on a dedicated 1ru hardware platform. The product features dual AC power and dual gigabit Ethernet.


Each codec send/receive pair can be connected to an associated pair at a remote location. The resultant LW+ AES67 Sources and Destinations appear within the Dashboard Input/Output lists in the same form as an xNode or any other connected AES67 stream. It is a good analogy to think of Infinity Link as a kind of VoIP based xNode with Infinity connections that can be used in the same way as and xNode, as part of a Partyline, Group, IFB, VP or for Peer to Peer communication.

The Infinity Link Advantage

Infinity Link is a competitive and flexible solution that allows the user to turn a standard Infinity Panel or Beltpack into a VoIP utility without compromising it’s use as a communications device. Unlike other solutions, the fact that the resultant streams are presented as LW+ AES67 audio and are made available within Dashboard as utility connections that are not restricted to use by the host device, means that the system has ultimate flexibility when configuring their use.

It maintains the matrix-free advantage of Telos Infinity but adds the ability to extend connectivity beyond the boundaries of AoIP
