The wiring between the ACU and the PABX analogue lines can be done in two
different ways. One way is to solder the 25 pole female sub D connector to the
PABX wiring (see

), the other way is buying an ACU-PABX connection cable
LBB 6721/03 (see
2.
).

Soldering the wires going to the PABX lines, to a 25-pole female sub D connector
(according the pin configuration in Table 6.2) and plug the connector on the PABX
connector of the ACU card.
