4.8 Base station synchronization
DECT base stations connected to S0 accesses of an LD4/LD4NX card and to the S0 integrated
accesses of seconde generation UCT2-S/UCT2S-12/UCT2-C or third generation UCT3-S/
UCT3S-12 cards are synchronized by the software, by the M bit of the S frame.
DECT base stations connected to integrated S0 accesses of a first generation UCT1-S/UCT1S-
12/UCT1-C card are synchronized by a third pair.
Figure 4-20: Connecting two DECT base stations to S0 accesses of a UCT1-S/UCT1S-12/UCT1-C card
When one DECT base station is connected to an S0 access of an LD4/LD4NX card and another
base station is connected to an integrated S0 access of a first generation UCT1-S/UCT1S-12/
UCT1-C card, a third pair also needs to be wired for synchronization.
