Functional Description
2.5.4
S/T Transmitter Disable
The transmitter of the S/T interface can be disabled by configuration (see figure 31). By
default (SCFG:TXD=0) both the S/T receiver and transmitter are active, but in order to
reduce power consumption, the transmitter can be disabled (SCFG:TXD=1) separately.
In power down mode the power consumption is reduced to a minimum and the IPAC
recognizes the activation of the S/T interface (incoming call). With several terminals
connected to the S/T interface, another terminal may keep the interface activated
although the IPAC does not establish a connection. In this case the IPAC receiver will
monitor for incoming calls while the transmitter is disabled, thus reducing power
consumption.
