Figure 4-21: Connecting two DECT base stations to an S0 access of an LD
4/LD4NX
card and a UCT1-S/
UCT1S-12/UCT1-C card
In certain special cases (multi-site network with PBXs of different types, for example, or a multi-
site network with several XSs whose base stations are connected to integrated S0 accesses of
UCT1-S cards), a third pair may need to be wired for synchronisation (pins 1 and 2 of the base
station RJ45 connector); see the Chapter “- Synchronisation multi-sites”, page 140.
Note:
NeXspan S12 and NeXspan C systems allow multi-site DECT synchronisation via a third
pair.
In a multi-site network with several NeXspan cabinets (XL/XS), synchronisation is carried out
from one or two PBXs declared "Master".
UCT-L (XL processor card) and UCT-S cards (XS processor card) have two RJ45 connectors for
DECT synchronisation: a primary port (J7A) and a secondary port (J7B) (see the Chapter “-
Synchronisation multi-sites”, page 140).
