8 x ASI/AES Access, Минск

The 8-port ASI/AES Access Module for the Nimbra 600 series of multiservice MSRs enables efficient transport of DVB-ASI video and AES and MADI audio

Customers around the world use the 8 port ASI/AES Access Module in audio and video production, post-production, contribution and distribution environments that require superb quality audio. It supports transport of eight completely independent ASI video streams, eight AES digital audio streams, or seven MADI streams, at different sampling rates with a guaranteed 100% Quality of Service independent of network load and topology. In addition to transport of DVB-ASI, AES3 and MADI standard audio signals, the module also supports compressed formats like Dolby® E and Dolby® Digital.

The ASI/AES Access Module can be configured to transport either DVB-ASI, AES/EBU audio signals or MADI streams.

In ASI transport mode, the module enables digital multimedia transport with guaranteed Quality of Service in studio, contribution and distribution networks. The module features a unique bandwidth preservation mechanism to keep the network overhead to a minimum for optimal use of network resources.

In AES/EBU mode, the module can transport up to eight AES/EBU audio signals. All standard sample rates are supported and the transport is fully transparent to all bits contained in AES3-2003 blocks, frames and sub-frames to provide support for alternative/compressed formats.

When configured for MADI transport, the module provides transparent transport of up to seven MADI streams, each including up to 64 AES channels.

Each port on the board can be independently configured as input, output or monitor. A port configured for monitoring can monitor any other port on the module. The architecture of the Nimbra system allows you to transmit and/or receive ASI video, AES/EBU audio channels or MADI streams with extremely low latency. The system’s jitter-free output signal eliminates the need for external synchronizers.

• 8 ASI ports, 8 AES/EBU ports or 7 MADI ports can be independently configured as In, Out or monitor
• Support for ASI bandwidths of 2 - 212 Mbps
• Support for AES/EBU sampling rates of 32/48/96/192/44.1/88.2/176.4 kHz
• Transparent MADI transport
• Transparent to compressed formats like Dolby® E and Dolby® Digital
• Transport perfect audio streams with 100% QoS and very high bandwidth utilization
• 1+1 network protection and < 50 ms recovery from loss of signal
• Very low jitter — does not require external synchronizers
• Supports point-to-point and multicast applications
• ITU-T G.826 performance monitoring

The ASI/AES Access Module provides inherent network redundancy and 1+1 protection with less than 50 ms recovery times, along with comprehensive fault and performance management, hot swap, and your choice of CLI, Web GUI or SNMP management.
