Remote Jack
The RJ-50 type 10-pin Remote jack on the back of innkeeper 1x/1rx is
for connection to the RS-232 cable (included), the optional
Remote Keypad or the optional
in-
terface (see Page 11).
The RS-232 cable can be connected to your other equipment to allow
remote control of the innkeeper 1x/1rx using any of the ASCII com-
mands listed on Page 10.
Dry Lines
Innkeeper 1x/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.
