The FreeSpeak Edge Base Station is a highly flexible, standalone 1RU device that provides extensive connectivity to a wide range of Clear-Com endpoints along with incorporating third-party Dante devices. Built primarily to deploy 5 GHz transceivers and beltpacks, the base station also provides support to FreeSpeak II splitters, 1.9 GHz E1 and IP transceivers/beltpacks*, and 2.4 GHz E1 transceivers/beltpacks. The base station also provides multiple software-defined interoperable IP ports that support both Dante and third-party devices. Direct connection to Clear-Com (or other Manufacturer's) wired end-points is possible through the 2-wire ports.

Please refer to the Clear-Com AoIP Network Recommendations guide for additional switch settings and network characteristics.

*Note: A 1.9 GHz beltpack cannot roam between and E1 1.9 GHz transceiver and an IP 1.9 GHz transceiver. Beltpacks on each system can communicate through the base station.
