OVERVIEW

IP Link 100c • IP Link 100e • IP Link 100n • IP Link 200 • IP Link MPXp

The Intraplex IP Link family of IP audio codecs provides high-end features at an affordable price.

Offering an array of audio coding options along with IPConnect technology for data tunneling, the IP Link codecs are suitable for use in Studio-to-Transmitter Links (STLs) as well as audio contribution and distribution networks. Support for IP multicast and multiple unicast streams enables one encoder to feed multiple decoders.

By incorporating three IP Interfaces that can be used for streaming and management, the IP Link systems can provide a level of reliability not seen in comparably-priced codecs.

As the latest additions to the Intraplex line of data transport products, the IP Link family of audio codecs bring legendary Intraplex reliability to the IP codec market.

Main Features of Intraplex® IP Link

IP Link 100c [IPL100C]: Portable, half-rack unit; single bidirectional stereo audio channel
IP Link 100e [IPL100E]: Modular plug-in card for Flexiva transmitters/exciters; single bidirectional stereo audio channel
IP Link 100n [IPL100N]: Single bidirectional stereo audio channel
IP Link 200 [IPL200]: Two bidirectional stereo audio channels
IP Link MPXp [IPL100MP]: Single stereo channel, analog composite FM multiplex signal IP encoder and decoder with front panel display and GPS timing capability
Standard: Linear, AAC-LC, Opus and G.722 audio coding
Optional: AAC-HE, AAC-HEv2, AACELD, MPEG2, MPEG3 and Enhanced aptX audio coding
Optional: μMPX Encode / Decode (IPL100C and IPL100E). Encodes a full FM composite MPX signal, including pilot and RDS, with perfect peak control with bitrate of 320 kbit/s
Optional: Automatic audio loudness leveling and metering compliant with EBU R-128 and ITU-R
Optional: IPConnect capability to reliably transport external IP packets
Other transport modes: Transparent AES up to 192 kbps to support composite FM multiplex signal over AES
Protocol Encapsulation: RTP, SHOUTcast/Icecast, MPEG-TS
Three independent IP interfaces for redundant network operation
Optional redundant power supply: 12VDC or 48VDC
Built-in silence sensor with optional stream switch over
Automatic backup to audio playout from USB drive or external audio source
Multicoding can encode the same audio source in multiple formats for STL, backup, and web streaming
Optional Dynamic Stream Splicing providing “hitless” operation and T1/ E1 circuit like performance on less predictable IP networks
Prioritized stream sources at the output with automatic switch over and switch back between primary and secondary streams and backup sources (streams, USB, external audio source)
Programmable RTP level Forward Error Correction (FEC) scheme
Programmable time diversity and interleaving of streams to combat burst packet losses
Integrated with Intraplex IP Link Scheduler for automated scheduled program switching
Integrated with Intraplex LiveLook (network analytics and monitoring software)
N+1 redundancy with integrated control of external switching equipment
IP Link 200: SynchroCast™ option provides dynamically managed precision delay for Single Frequency Network (SFN) broadcasting and simulcasting
Support for IP multicast and multi-unicast
Web browser user interface and SNMP network management
Eight multipurpose contact closure inputs and outputs provide:
- Transport of logic signals with time-alignment to audio
- Stream control
- Alarm notification
