Headquartered in West Chester, Pennsylvania, Aviom produces distributed audio networking gear which uses a proprietary digital audio transport system called A-Net, based on the physical layer of Ethernet and carried over Category 5 cables terminated with 8P8C connectors.
The GG45 (where GG stands for GigaGate, and 45 is to remind the backward compatibility with the 8P8C modular connector - often colloquially called RJ45) is a connector for high-speed Category 7 cable (generally known as Cat 7) LAN cabling developed by Nexans.
The HP-HIL bus uses specific 4-pin, 6-pin, or 8-pin SDL connectors, somewhat similar to the 8P8C 8-pin modular connector commonly (though incorrectly) called the RJ-45.
The XJACK was originally used in modem and network cards, to attach a standard RJ11 or 8P8C plug directly to the PC card.
