AN
149: Ring Transfer Circuit
This application provides a latching contact closure generated
after X number of rings. It is used to automatically transfer ringing to another
phone when the target number of rings is reached. The circuit automatically
resets if either the original extension or ring target phone goes off hook. This
configuration uses WTB circuits in conjunction with an inexpensive digital
timer.

AN
148: Voice Mail Rebooter
This application allows a momentary contact closure to be
generated after X number of rings. It is used to automatically reset a computer
based Voice Mail system when the system fails to answer after an adjustable
number of rings. Line answer resets the unit under normal conditions. This
configuration uses WTB circuits in conjunction with an inexpensive digital
timer.

147:VoIP
Contacts The main purpose of the Wizard's Tool Box Circuits is to derive
contact closures from traditional tip and ring analog telephone circuits.
They are, however, finding many applications in interfacing VoIP equipment to
existing phones and lines. The line powered, dry relay contact, is perfect for
interfacing VoIP boxes to the real world. This applications covers
stacking multiple WTB-860617-40 loop detectors for multiple contacts.

AN 146:
Digital Tone Trigger This is an
interesting application that allows custom ring tone music riffs to be generated
for individual lines with the incoming call picked up anywhere in the house. It
relies upon , WTB-871120-20HS Ring Detectors, WTB-871120-10 Universal Voltage Relay,
TOA Message Repeater and a Panasonic phone system.
While any phone system with directed call pickup and analog extensions would
work it's second nature to the Panasonic. A TOA 900 mixer was also used to feed
an existing whole house audio system, which was
also a bit of a prerequisite.

INSTALLER TIP: The Wizards
Tool Box Circuits™ are sized so that will fit on the back
of a standard 66M-150/89B telephone connection block. This makes multiple
connections and interface easy and creates a professional looking block field
for your special circuit installations. (Click on the image for details)
AN 140:
Impulse Generator Originally used as a retrofit
hookswitch
flash generator the AFU-48SF can also be considered a 500ms impulse generator.
When coupled with a our standard loop detector a combination can be created that
will extend a too short CPC pulse (quick line interruption) to 500ms. This is
extremely useful in situations where a short CPC pulse is not recognized by a
KSU or Voice-Mail.

AN 141:Gate
Contact from Spare CO Port This handy application allows a contact closure
to be generated from a spare KSU CO line port. Originally this was used as a
hold open function for a gate control. CO ports can be optioned to only be
available to certain phones thru most KSU software.

AN 142:Pansonic
Doorbell Interface The old style Panasonic 308, 616, and 1232 KSU do
not have a door bell trigger circuit similar to the new 624. This circuit was a
way to generate the function for the older KSU's.

AN:143
Call Hold with Contact Originally configured to indicate that a standard
2500 type set on a manufacturing plant floor had placed a call on hold and
trigger a small indicator strobe light. Another 2500 set in parallel on the line
then simply went off hook to get the call. The key was the contact closure to
generate the strobe, and the hold switching action of the circuit.

Panasonic Hybrid Phone Audio Mute
When using Panasonic hybrid telephone sets such
as the 7100, 7300, or 7700 series this circuit generates a contact closure when
the phone goes off hook and is perfect for supplying a mute contact to an audio
system configured to mute with a contact closure. This is often the case in
weight and exercise rooms.

LED to Contact Converter Using the high sensitivity and low current draw
of the WTB-860617-40 an LED appearance can be converted into a contact closure
while maintaining the LED indication.
