Its most important features are:

· IP Multicast, Unicast and Multi-Unicast (optional) audio streaming transmission/reception.

· X.21 interface for transmission/reception over leased lines .

· ISDN terminal adaptor with S/T and U interfaces(optional).

· 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.

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

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

· The Ethernet port is used for audio transmission and control. The unit can be controlled from a Web Browser   and/or ProdysControl application, which lets the user manage not only many simultaneous PronoNetLCs, but also any   Prodys codec (Pronto2/3, ProntoNet, Kronos…).

· ProntoNetLC Decoder offers fully TCP/UDP/IP connectivity via a 10Base-T/100BaseTX Ethernet port,   supporting the following protocols :

    · DHPC: IP address auto configuration.
    · RIP: Internal/Alias IP addresses can be assigned.
    · SNTP: Clock synchronization.
    · SNMP: Remote management over SNMP protocol.
    · HTTP: A Web server allow the user to monitor/configure the unit from a Web Browser.
    · IGMP: This protocol deal with Multicast traffic.
    · ICMP: IP control protocol.
    · SMTP: Simple Mail Transfer Protocol.
    · DNS: Domain Name Server.
    · IP Compatibility: SIP/SDP/RTP accoding to the standard for IP compatibility defined by the N/ACIP project within the       EBU group.

· ProntoNetLC is equipped with a stereo balanced analog audio input/output (XLR-3 connectors) with 24 bits A/D-D/A   converters, and AES/EBU digital (9 way D type connector) audio input/output. The AES/EBU interface provides input for   external clock.

· 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.

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

· Headphone monitoring of audio outputs (jack connector) from the front panel, with volume control.

· Most important industry-standard algorithms: PCM,G722,MPEG1/2 Layer II/III. Optionally AAC   and apt-X.

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

· Independent encoding/decoding operation.

· Auxiliary data along with the encoded audio through two user configurable RS232 ports (RJ45 connector) at 300,1200,   2400, 4800 or 9600 baud.

· Up to seven user configurable general purpose input-outputs (open-collector signals, 25 way D   type connector). These GPIOs can be used as end-to-end contact closure they can also be user configured, so inputs   can be set up to control audio inputs or reset alarms, and outputs can be configured to monitor line status,   audio synchronization or alarms, among other options

· Streaming advance features:

    - Jitter correction buffer. This adjustable buffer avoids audio dropouts compensating for up to 10 seconds of jitter        in the IP connection.
    - The unit automatically adjusts in synchronisation with the transmitter site rate, to give a constant delay        in IP communications.
    - The frame size is user configurable, to give full flexibility when adjusting the delay and bandwidth use.
    - The codec provides a test tool which allows the user to check the bandwidth, delay and jitter in the        IP connection. This information can be used to adjust the streaming parameters and so, to obtain the best-quality        in the real-time audio reception.

· Local or remotely (TCP/IP) upgrading of one or several units at once using the same utility, which is also   compatible with ProntoNet units. Factory software upgrades can be downloaded.

· Alarms: Real Time alarms management through SNMP traps and e-mails .
  The alarms are saved in non-volatile memory. It is possible to have an historical log of events even if the unit   was disconnected from the network.
