February 2013 Telephone Dialer with Recorder DNA934P
INTRODUCTION
The DNA934P is an interface used for connecting the Intercom Central Exchange to a
telephone line connected to a PABX or the Central Office. One FXO Port is provided.
Recorder messages, phone numbers, number of rings and number of times to play the Caller ID 
message are programmed using a master intercom station and a DNA100/PC.
The DNA934P is compatible with CB901EX, RM5000EX and CB901CA.
OPERATION
The DNA934P Interface transfers calls from the intercom exchange to the telephone network.
Up to 4 telephone numbers can be programmed. If a Busy or Ring-No-Answer is encountered then the 
next number on the list is dialed. If all 4 numbers are busy or no one answers then the dialer will 
continue to dial all 4 numbers until one of the numbers answers.
When the dialed telephone answers, a recorded message is played to that telephone. This message 
will identify the name and address of the building where the call is coming from. Following this 
message the called party will receive a message identifying the intercom number that placed the call. 
The final message instructs the telephone operator to accept the call by dialing #1 or to refuse the call 
by hanging up. These messages are repeated 3 times (programmable) or until the #1 is dialed. If the 
telephone operator does not dial #1 or hang up then the next number on the list is dialed 
automatically. While in conversation the telephone operator may replay the caller ID message by 
dialing #2.
