Introduction
Innkeeper PBX will allow you to send and receive audio
through your multi-line PBX, ISDN or analog telephone.
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?
The innkeeper PBX digital hybrid connects audio signals to
and from the handset side of a telephone without the varia-
tions in quality found with analog hybrids. The main function
of a hybrid is to bring in the caller’s voice from the phone line
as clear and clean as possible. In the real world, when you
send your voice down the telephone line it has a tendency to
bleed over into the caller’s audio. The hybrid must adapt to
the audio signals from the telephone in order to properly
separate transmit and receive audio. We use a 16 bit DSP
(Digital Signal Processor) to continuously monitor the phone
line and local audio signals to deliver excellent trans-hybrid
loss, also known as separation. Our dual-convergence algo-
rithm can achieve excellent separation, typically exceeding
50 dB.
Ready to go?
The innkeeper PBX controls and connectors are clearly
marked and ready for operation. The Features diagrams and
Operation sections on the following pages will help you pin-
point any minor questions that you may have. If this is your
first exposure to a hybrid, we suggest that you read the entire
manual to allow you to take advantage of all these features.
Any Questions?
Before you pick up the phone... Please thumb through the
rest of this manual. You might find those deep technical
questions are covered on later pages.
