  • Member of JumboSwitch Product Family

"Over the past thirty-five years I have used similar boxes from other vendors for similar applications. But I have never seen one that would produce such a linear, uniform audio transmission from one end to the other - especially across an IP link.”
- Martin T. Vinson, N.C.T., A.S.C.E.T.

Applications

Typical applications include linking or extending various 600Ω analog, audio and intercom devices, (e.g. Frequency Shift Keying [FSK] modems), E&M, teleprotection relay controllers, and dry contacts over Layer 2/3 IP networks.

It is also used to improve voice quality and increase system reliability in harsh environments, to replace unreliable leased phone circuits and to stabilize voice level settings for 600Ω audio channels.
