The OMN-ARNIE is a high-performance network synchronizer designed to enhance the scalability of OMNEO systems. It acts as a DHCP server, DNS-SD server, and Precision Time Protocol (PTP) synchronization device for large-scale audio-over-IP networks. This device provides essential functions to ensure seamless and reliable operation across multiple subnets.

Key Features

• DHCP Server: The OMN-ARNIE serves as a Dynamic Host Configuration Protocol (DHCP) server, eliminating the need for IPv4 Link Local (IPv4LL) protocols. It supports one subnet when no DHCP server is available and can manage device allocation for up to 450 OMNEO devices.
• Scalable Device Support: It supports up to 450 OMNEO devices across multiple subnets. When paired with an OMN-ARNIS device, the system can scale to support up to 10,000 devices across 40 subnets.
• PTP Clock Synchronization: The device supports Precision Time Protocol (PTP), ensuring accurate audio clock synchronization across multiple subnets, with OMNEO devices acting as the grandmaster clock.
• DNS-SD (Domain Name System Service Directory): Allows seamless discovery of all OMNEO equipment in a routed network, avoiding the need for Multicast DNS. This simplifies network configuration and reduces traffic load.
• Redundancy Support: OMN-ARNIE supports system redundancy, ensuring continuous operation and failover protection in the event of network disruptions or failures.

Scalability and System Configuration

The OMN-ARNIE is designed for scalable audio networks:

• Without OMN-ARNIS: Supports up to 450 devices across 5 subnets with a maximum of 90 devices per subnet or 10 subnets with 45 devices per subnet.
• With OMN-ARNIS: Supports up to 10,000 devices across 40 subnets, enabling extensive and complex audio-over-IP configurations across larger installations.

The OMN-ARNIE provides critical network services, ensuring that large-scale OMNEO systems operate smoothly, efficiently, and reliably. Its ability to manage multiple subnets, provide DHCP, DNS-SD services, and synchronize clocks over multiple IP subnets makes it a vital component for complex, high-performance networked audio systems.
