Professional Digital Voice Announcer

for Ring Trip Applications!

The DVA-LP is an economic non-volatile digital voice
announcer specifically designed for applications
requiring simple ring trip announcements.

The DVA-LP can be used in any application that
requires an inexpensive announcer to play a single
message. The DVA-LP will answer the incoming call

on the first ring, play your pre-recorded message
and then disconnect. If desired, the message can be repeated up to a programmable
limit of 99. The message is remotely recorded using Touch Tone commands.

The announcer provides up to 16 seconds of high quality record time and is powered
by the telephone line.

When the DVA-LP detects an incoming call, it will answer the line immediately and begin playing the pre-recorded
message. When the message is finished, the DVA-LP will pause, and repeat the message until the rmessage playback
counter is met or a CPC signal is detected on the incoming line. Anytime after the DVA-LP has answered, if a Q is
entered, the DVA-LP will stop playing the message and monitor for the security code (see Programming section B).
