Figure F–1 shows an example of how to connect two MC145572 U–interface transceivers as a
repeater.
Figure F–2 shows how an MC68HC05 MCU can be connected to the MC145572 and MC145474
in an NT1 application.
Figure F–3 details the MC68302 serial interface connections to the MC145572 and MC14LC5480
for an ISDN U–interface terminal.
Figure F–4 shows an ISDN smart NT1 application with the MC145572 and MC145574 in NT ter-
minal mode.
Figures F–5 and F–6 show two different remote access multi–line configurations.
Figure F–7 gives an example of a multi–line U line card.
