Audio to IP
Although Audio to IP (AoIP) networks is typically used by broadcasting companies, it is also used in private IP networks. Advancements continue to be made in audio quality and delay; however, many proprietary systems still exist to transport high quality audio over IP.
Audio to Ethernet or IP is a common requirement for professional network managers and audio over IP quality is improving and is now commonly used in LANs, WANs, Internet or any other IP network.
The “toll quality” standard is being reexamined because frequency limitations on PCM-based encoding make conversations sometimes difficult to understand. However, expanding the frequency range coverage in wideband audio codecs has gone a long way to improve quality for most audio over IP situations.
Industry Examples
Audio to IP applications are frequently encountered in LAN and WAN environments, especially transportation sites such as railroad facilities and airports. Applications frequently center around emergency communications, security, surveillance and broadcasting.
TC Communications’ Audio over IP Devices
Audio over IP requires extremely low latency and the JumboSwitch product family offers the ideal interface card. The TC3846-6 Analog + Dry Contact IP Gateway links or extends 4 channels of 600? 2/4 wire analog and 4 channels of dry contacts across Layer 2/3 Ethernet networks. It is simple to configure and supports point-to-point and point-to-multipoint topologies.
The TC3846-6 supports frequencies from 300Hz to 3.4KH and achieves minimal end-to-end processing delay (latency) by using high performance buffering and forwarding technology. The TC3846-6 is capable of running continuous pilot tones without interruption or quality degradation. This is possible because the usage of proprietary technology that, unlike VoIP, uses a common clock for both ends. The analog signals ride on a 64Kbps channel without compression.
