Installing an Analogue Connection Unit (ACU)
LBB 6725/xx and LBB 6726/xx
6.1 Functional description
The Analogue Connection Unit (ACU), which is mounted in the DCU, is an interface
unit between the DCU and the telephone exchange (PABX) analogue lines.
Each ACU contains 8 analogue lines in which each line represents a DECT6000
handset. The ACU also functions as a galvanic isolation between the DECT6000 system
and the PABX. One DCU can contain up to 8 ACUs. Figure 6.1 and 6.2 shows the
situation without and with the use of a DCU. If possible existing telephone wiring may
be used as shown in example below.
