The LH16X card is used to connect 16 analogue hotel terminals to An Aastra XL/XS iPBX.
The LH16X card offers the same features as the LA16X card, plus an extra feature that
lights up an LED on sets if messages have been left (for hotel configuration).
4.14.11.2 Functional description
The LH16X card has the same features as the LA16X card (see Section4.14.1.2), plus an
extra feature that lights up an LED to inform the user connected that a message has been
left (example of use: hotel customer reception).
The LED signal command is sent to the central unit (UCV card), which activates a high
voltage current generator built into the card providing the power supply (105 V DC)
required for the operation of the lamps on hotel sets.
