Each Line Interface Board (LIB) must have a unique 3 digit address number to operate properly with
the Ovation system. These addresses are set using the "decade" switch (or switches) located at the
top of the LIB (see Figure 11).
Address numbers take the place of the telephone numbers you would program
into a normal telephone entry system. If LIB address numbers are duplicated,
the Ovation system will operate incorrectly.
•
There are two different types of LIBs: Single decade switch and three decade switch types. The
switches are located in the upper right-hand corner of both types of boards. In order to properly set the
LIB addresses, please refer to the appropriate section for your installation.
1. SINGLE DECADE LIB SWITCH
Single decade switch LIBs should be used only when there are 10 or less LIBs in your
installation. Set single decade switch LIB addresses as follows:
1. Set LIB address numbers by working from right to left, starting with the number 0. For a 10 LIB
installation, the decade switch on the the far right LIB will be "0" and the decade switch on the
far left LIB will be "9".
2. When programming a single switch LIB, the first two numbers are considered to be "00". So
the LIB address for the second LIB from the right will be "001".
Once LIB addresses are set, finding individual line addresses is easy. In a 10 LIB installation:
•
The third line on the second LIB from the right will have an address of 00103, because 001
is the LIB number and 03 is the line number.
•
Tthe fourth line on the tenth LIB will have an address of 00904, because 009 is the LIB
number and 04 is the line number.
