ProntoNet LC Audio Codec.

ProntoNet LC

Customisable Audio Codec for IP, ISDN and X21

ProntoNet LC enhances the PRODYS IP audio codecs family, offering a subset of those features provided by ProntoNet. ProntoNetLC is a multi-algorithm stereo audio codec over IP, X21, 3G and ISDN, supporting many popular coding algorithms i.e. G722, MPEG1/2 LayerII, MPEG1/2 LayerIII and uncompressed linear audio (PCM). Other compression modes such as AAC or apt-X are offered as an option.

Each ProntoNet LC fully support IP (TCP and UDP), terminated with a 10BaseT/100Base-TX Ethernet port (RJ45 connector). This enables remote monitoring/configuring and data/audio transportation over data communication links (LAN, WAN, Internet…)

ProntoNet offers fully TCP/UDP/IP connectivity via an Ethernet port.
IP Multicast, Unicast and Multi-Unicast (optional) audio streamingtransmission/reception.
IP Compatibility: SIP/SAP/SDP/RTP/STUN protocols are supported according to the standard defined by the N/ACIP project within the EBU group.
Prodys NAT Traversal Streaming Protocol permits router firewall pass-through with zero configuration.
FEC (Forward Error Correction). Up to 24 different schemes are available, to fit to the desired delay and available bandwidth.
Error Concealment mechanisms on Mpeg audio modes are supported to reduce the impact of packet losses.
Prodys Real time Network Analyzer to monitor critical network parameters in real time during the connection.
Streaming advance features:

Automatic Jitter buffer. This adjustable buffer avoids audio dropouts compensating for up to 10 seconds of jitter in the IP connection.
Automatic synchronization adjustment with the transmitter site rate, to give a constant delay in IP communications.
User configurable frame size, to give full flexibility when adjusting the delay and bandwidth use.
Test tools 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.

X.21 interface for transmission/reception over leased lines.
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 from 300 to 115200 bps.
The Ethernet port is used for audio transmission and control. The unit can be controlled locally from its front panel, or remotely from its Web Page or from ProdysControl.
Local or remotely (TCP/IP) upgrading of one or several units at once using the same utility. Factory software upgrades can be downloaded.
Call facilities: Auto-redial, call scheduler and log systems.
N+k Prodys Redundancy Protocol allows K backup IP codecs to provide resiliency for up to N active IP codecs.
User Access Control to define different access restrictions in a per user basis.
Configuration presets to define different configurations for all or some specific parameters.
Up to seven user configurable general purpose input-outputs (GPIO). 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.
Alarms: Real Time alarms management through SNMP traps, GPO and e-mails
Headphone monitoring of audio outputs (jack connector) from the front panel, with volume control.
Optional:

ISDN terminal adaptor with S/T and U interfaces.
ISDN Compatibility: Fully compatible with all major audiocodec manufacturers, supporting the most important bonding algorithms: J52, Telos and CCS bonding.
BackUp System: ISDN as a secondary link for IP/X21.
Additional LAN Management port to split audio and control data flows.
