Wiring DECT base stations
Each terminal is connected to the ISDN S0 (BRI) interface of an LD4NX card, and uses
2 pairs: 1 transmit pair and 1 reception pair (refer to document [6] (see Section1.3) for
more information).
If there are a DECT base station and an S0 terminal supplied with 40 V (other than the
base station) on the same card, the base station will be powered with a 40 V (available
only on an AXL cabinet).
