IA12 ISDN ADAPTOR

Notes:

•   Filter bit: If it is active, no comparison takes place between the ISDN line numbers 

 

and the incoming calls, otherwise they are compared: It is required that the filter bit 

 

is active for the DDI ISDN lines. 

 

 

The “Filter Bit” is active by default.

•   DDI selection: If it is active, then the ISDN line is defined as DDI, else as MSN.   

 

 

DDI is active by default.

•   Automatic  line  configuration:  If  it  is  active,  then  the  information  of  whether  the 

 

ISDN line is Point-to-Point or Point-to-Multipoint is figured out through automatic 

 

tests  performed  on  the  line.  Otherwise,  the  configuration  is  supposed  to  be  set 

 

through programming.

 

 

It is active by default. 

•   Point-to-Point  connection:  If  it  is  active,  then  that  indicates  that  the  structure  of 

 

the ISDN line is so as only one device can be connected to it. Otherwise, the line has 

 

Point-to-Multipoint structure and more than one device can be connected to it. 

 

By default it is not active for the IA12 motherboard, but active for the expansion card.

USAGE

IA12 ISDN Adaptor starts functioning automatically after the installation and programming 

is finished and the PABX is powered on. This can be easily checked via the LEDs on the 

motherboard.

The relevant information (like CLIP, AOC, etc.) about the ISDN calls are sent to the PABX 

from IA12 through the serial data line. The information is sent to the display of the Karel 

Feature Phones or Karel Consoles and preserved in the system memory to be used in 

the Call Recods.
