Raven electronics analog orderwire 41610
This description is directly from the Raven Electronics website.
Starting with the basic 41610 or 41611 System, other plug-in modules can be added, providing a system configuration designed to specific requirements. The Raven Analog Orderwire provides an interface between a 4-wire line, a frequency limited voice path and a wideband data path. A 4-wire transmit port is provided by the Transmit module, which sums inputs from the handset MIC and a wideband data input. A low pass filter in the voice path band limits signals from the handset MIC.
A 4-wire receive port is provided by the Receive module. From this input, the Receive module provides a wideband data output and a voice frequency output (limited by a low pass filter) to the speaker or handset receiver (to speaker when ON HOOK, and to the handset when OFF HOOK).
Standard Orderwire decodes one or two DTMF address codes to ring the Orderwire and/or are optional Telephone Interface or PSTN Interface. Discrete tones can also be used for calling an Orderwire.
