Introduction

Welcome to Telos Zephyr Connect

Welcome to Zephyr Connect, a containerized multi-codec gateway designed to work with the Livewire® AoIP standard used by broadcasters worldwide. It offers resilience, even when connections are challenging.  Networks worldwide use Zephyr Connect for distribution and contribution.

Zephyr Connect transports multiple (up to 64) channels of stereo, mono, and dual-mono audio across IP networks, including private WANs, IP-radio links, and over high quality public Internet connections, perfect for large-scale distribution of audio to single or multiple locations.

Zephyr Connect is a high density codec. The minimum configuration includes two bi-directional stereo codecs. You can license additional codecs up to a maximum of 64 per container. Zephyr Connect interfaces to your existing Livewire® Network using a single ethernet cable for all I/O.

Coding algorithms include AAC, AAC-LD, AAC-HE, AAC-HE v2, MP2, MP3, linear PCM, and optional Enhanced aptX™. (Enhanced aptX™ is a licensable option.)

Dual, diverse-path, end-to-end connections are available for ultra-reliability and redundancy. Built-in streaming servers use SHOUTcast/ICEcast formatting at the output.

  • Bitrates of 32 - 320 kbps are available for the AAC encoder.

  • Bitrates of 64 - 320 kbps are available for the AAC-LD encoder.

  • Bitrates of 24 - 96 kbps are available for the AAC-HE encoder.

  • Bitrates of 24 - 56 kbps are available for the AAC-HE-V2 encoder.

  • Bitrates of 24 - 320 kbps are available for the MP3 encoder.

  • Bitrates of 96 - 320 kpbs are available for the MP2 encoder.

  • Bitrates of 256 or 354 kpbs are available for the Enhanced aptX™ 16 bit encoder.

  • Bitrates of 384 or 576 kbps are available for the Enhanced aptX™ 24 bit encoder.

  • Uncompressed 48 kHz stereo audio is transmitted at 2304 kbps.

Zephyr Connect offers MPEG-standard ancillary data transport, up to three transparent control and metadata channels per codec and direction, and enhanced GPIO options with up to 20 end-to-end GPIO channels per codec and direction, all bundled and synchronized with the respective audio content.

An optional Content Delay feature allows independent local storage and scheduled delayed playout of any or all coded audio channels.
