4.5.5 Connecting base stations
Each terminal is connected to an ISDN S0 (BRI) interface of an LD4NX ST card, and uses two
pairs: 1 transmit pair and 1 receive pair.
Note:
If there are a DECT base station and an S0 terminal (other than the base station) on the
same card, the base station must be powered with a 40 V supply.
