5.2.7 Connecting the LDS card
The LDS card is connected to the distribution frame by a special cable, also used for the remote
power supply connection and the RSU connection if a T0 interface is synchronising on the LDS
card.
If there is no synchronising T0 on the LDS card, cable HG4301A or B is used.
The remote power supply connection requires a PLDS card used to retrieve the 40 V ISDN or the
48 V Subscriber on the back panel. The PLDS is positioned as an equipment card cable
(LAJ,LAB etc.). It is inserted in a slot between the equipment cable and the back panel
connector.
