JK Audio innkeeper 1x/rx - Manual (Page 2)

Introduction
Innkeeper 1x and innkeeper 1rx 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 miserable audio path.
What is a Digital Hybrid?
A digital hybrid connects audio signals to standard analog telephone lines
without the variation 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 phone line to properly separate
transmit and receive audio. We use a 16 bit DSP (Digital Signal Processor)
to continuously monitor the phone line and audio signals and deliver
excellent separation. Our dual-convergence algorithm can achieve
excellent trans-hybrid loss, typically exceeding 50 dB, without any setup.
Ready to go?
The innkeeper 1x/1rx controls and connectors are clearly marked and
ready for operation. The innkeeper 1x comes in a desktop case and the inn-
keeper 1rx has a rack mountable case. All features and operation are the
same. The Features diagrams and Operation sections on the following
pages will help you answer 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.

FCC Registration (continued)
b) The telephone equipment's FCC registration number. This
can be found on the bottom of your telephone equipment,
and,
c) The ringer equivalence number (REN) for this equipment.
The REN is used to determine the quantity of devices which will
be connected to the telephone line. Excessive RENs on the
telephone line may result in the devices not ringing in response
to an incoming call. In most, but not all areas, the sum of the
RENs should not exceed 5.0. To be certain of the number of
devices that may be connected to the line, as determined by the
total RENs, contact the local telephone company.
3. Repair
Instructions
If it is determined that your telephone equipment is
malfunctioning, the FCC requires that it not be used and that it
be unplugged from the modular outlet until the problem has been
corrected. Repairs to this telephone equipment can only be
made by the manufacturer or its authorized agents or by others
who may be authorized by the FCC. For repair procedures,
follow the instructions outlined under the warranty section of the
manual.
4. Rights of the telephone company
If telephone equipment is causing harm to the network, the
telephone company may temporarily discontinue your telephone
service. If possible, they'll notify you before they interrupt
service. If advanced notice isn't practical, you'll be notified as
soon as possible. You'll be given the opportunity to correct the
problem, and you'll be informed of your right to file a complaint
with the FCC.
Your telephone company may make changes in its facilities,
equipment, operations or procedures that could affect the proper
functioning of your JK Audio product. If such changes are
planned, you'll be notified by your telephone company.
