Nereus Data Sheet
Prodys Codec comparison Table

Nereus is a Multiple IP/ISDN/X21 Codec in a 3U rack, which can house up to 14 IP audio modules or up to 7 couples of IP+ISDN/X21 audio modules.
Nereus supports individual remote control of each audio module via embedded web server or centralised management via ProdysControl application.

Key Features:

• High quality audio streaming over TCP/IP, ISDN or leased lines.
• Configurable and scalable system: Up to 14 audio IP modules. Up to 7 couples of
• IP and ISDN/X21 modules.
• Widest range of industry-standard coding algorithms as standard
  from apt-X to Mpeg4 AAC LC,LD & HE.
• Hot-swappable.
• AC or DC Redundant Power Supply.
• BackUp System: ISDN as a secondary link for IP/X21.
• Powerful Alarm System: Management via SNMP/GPO/email.
• Multicast, Unicast and Multi-Unicast with up to 10 connections per module.
• Prodys Real time Network Analyzer to monitor critical network parameters in real time during the connection.
• Meets the initial standard for IP compatibility of the EBU group: SIP/SAP/SDP/RTP.
• AES/EBU User Bit channel transportation and AES/EBU transparent transmission
  over IP.
• Easy configuration to optimize link for low delay, jitter and utilization.
• Call facilities: Auto-redial, call scheduler and log systems.
• Independent encoder/decoder operation and automatic detection of the encoding mode.
• FEC (Forward Error Correction) is supported as per the RFC 2733 standard.
• Prodys NAT Traversal Streaming Protocol (v3) permits router firewall pass-through with zero configuration.
• N+1 Prodys Redundancy Protocol allows one backup IP codec to provide resiliency
  for up to N active IP codecs.
• Prodys PLL algorithm compensates for sampling clock jitter and assures consistent audio integrity and delay over IP.
