Introduction Innkeeper multi line digital hybrids will allow you to send and receive audio over analog telephone lines. While this may seem like a simple task that any telephone can do, the challenge is getting the best quality audio from such a limited audio path. What is a Digital Hybrid? A digital hybrid connects audio signals to a standard analog telephone line without the variations in quality found with analog hybrids.

Operation Connecting Cables Although each application will require a slightly different setup, following is a general cable connection setup and explanation. Phone Line - Connect the supplied RJ-11 phone line cable(s) between the RJ-11 jack(s) marked "Line" and your analog phone line jack(s). Be sure these jacks can support standard analog telephone operation. The Innkeeper 2/4 will not work with "dry pair" phone line connections.
Operation (cont) Transmit Signals The bi-color Send LED displays the signal level as it goes out over the phone line. The LED will display transmit signal levels at -20 dB as green and indicate clipping at -3 dB as red. The goal is to drive the phone line at high enough levels to avoid phone line noise, but not so loud as to cause excessive clipping. Adjust your Send audio signals to a level slightly less than the point where you see occasional flashes of red on the Transmit LED.
Operation - Conference Conference(innkeeper 2 only) One press of the conference button will join the audio paths of both line one and line two, providing there are calls present on both lines. A second press of the conference button will break the audio paths between the calls. An auto-dropped or manually dropped line will automatically break the conference. By default line1 send and line 2 send audio will be mixed together digitally and sent into both phone lines.
