Operation (continued)
Auto-Answer
The Auto-Answer feature will answer on the first ring. When Auto-
Answer is enabled, you can still take calls manually using the call
button. When finished, you can either drop the call manually or allow
the call to Auto-Disconnect. Innkeeper 1rx will look for a CPC
(calling-party-control) disconnect signal or ROH (receiver-off-hook)
message from the phone company to determine when a call has
disconnected. This can take up to a minute.
1 kHz Tone Generator
The 1 kHz tone generator is used for setting levels. When pressed
once a full scale 0dB maximum output level signal is sent down the
phone line. This will allow you to calibrate levels at the other end of
the call. When pressed again, this same signal is sent to the caller
output only. This will allow you to calibrate the signal level at your
console. The tone generator is disabled when pressed a third time.
Dry Lines
Innkeeper 1rx was designed to work on standard (wet) telephone
lines as well as on custom pbx (dry) lines. Dry line installation is
always a custom configuration and requires substantial telephone
system knowledge. These installations are found in radio and
television studios for both PBX and intercom applications.
Wet lines are typical tip / ring telephone lines that carry ring voltage,
talk battery, and full duplex, balanced audio over two wires to an
analog telephone. Dry lines carry the balanced, full duplex audio but
without the ring voltage or talk battery. innkeeper does allow dry line
operation with a few limitations:
• If talk battery is not present when the Call button is pressed, a
dry line is assumed.
• If talk battery suddenly appears during a “Dry Line” call, it
becomes a wet line call, and auto-disconnect will occur when a
disconnect signal occurs, or if talk battery disappears.
• Auto-answer does not work on a dry line.
• The aux telephone jack will not support an analog telephone
during a “Dry Line” call.

For whichever input channel you have the Caller connected to, turn the
corresponding Aux control to minimum (usually hard left). All other Aux
controls should be set for what you want to send to the phone line. Each
Aux Send bus is completely separate from all other outputs, so these Aux
controls will not affect what is heard on the Main outputs or on any other
Aux buses. This Aux Send bus should be pre-fader, so you can use the
fader controls to set the levels of each channel to the main output.
Auxiliary telephone optional.
Used to dial out to set up calls.
