6.2.6 LDS card layout
The LDS card can be fitted in the shelves in accordance with the configuration file. The card is
connected to the synchronous bus via the AVADQ or AVLDT terminator inserted in a CFX front
slot (corresponding to CLX slot on the LDS card).
For more details, refer to "Reference documents" on page 13.
The LDS card must be connected to a synchronising clock input in the PBX if a T0 interface is
synchronising on the LDS card.
Each group of eight S interfaces must be connected to a complete junction (32 TS) on the
synchronous bus of the NeXspan 50. The LDSA card thus requires two junctions.
To synchronise the NeXspan 50, connect the ISDN clock extracted from a T0 access
(synchronising T0 interface) to a 2.048 MHz clock input of the RSU.
