4.14.4 LA8 card
4.14.4.1 Description
The LA8 card is used to connect 8 analogue set lines to an iPBX.
4.14.4.2 Functional description
The LA8 card is functionally identical to the LA16X card (see section 4.14.1.2) except for
the following differences:
• it ensures interfacing with only 8 analogue sets,
• the parameters for converting digital signals into analogue signals and from analogue
signals to digital signals are not loaded into the memory of the LA8 card when started,
but pre-programmed in the card at the factory.
