· ISDN Universal terminal adapter S/T or U interfaces worldwide.

· X.21 for synchronous data transmission links.

· LAN Interface 10/100 Base-TX Ethernet for control and audio transmission. Unicast, Multicast and Multi-Unicast IP   connections.

· Stereo Analog or digital (AES/EBU). The AES/EBU interface provides input for external clock.

· Easy configuration to optimize link for low delay, jitter and utilization.

· Prodys Real time Network Analyzer to monitor critical network parameters in real time during the connection.

· 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 coniguration.

· N+1 Prodys Redundancy Protocol allows one backup IP codec to provide resiliency for up to N active IP codecs.

· Full management of all functions including audio levels with user friendly ActiveX web interface.

· Dolby E transmission over IP (by using AES/EBU I/O in transparent mode).

· Dual operation (two fully independent communications) in G711, G722, Apt-X and MPEG.

· MPEG1/2 Layer II/III, MPEG AAC LC/LD/HE and Apt-X standard and enhanced.

· Independent operating encoding and decoding modes.

· Automatic detection of the encoding mode used by the remote unit.

· ISDN Compatibility: Fully compatible with all major audiocodec manufacturers, supporting the most important bonding algorithms: J52, Telos and CCS bondings.

· IP Compatibility: SIP/SDP/RTP protocols are supported according to the standard for IP compatibility Tech 3326 defined by the   N/ACIP project within the EBU group.

· Auxiliary data in all MPEG and Apt-X modes.

· User configurable GPIOs. Posibility to configure them as remote contact closures.

· Alarms: Real Time alarms management through SNMP traps and e-mails.

· Local or remotely (TCP/IP) upgrading of one or several units at once. Factory software upgrades can be downloaded.

· BackUp: Integral backup feature to assure program continuity. ISDN can be used as a back line in the event of a failure   of the IP or X21 lines.
