Application—Private line automatic ringdown (PLAR)
A private hot-line can be created by using two FXS models back-to-back (see
figure 11
). These can be found
in use as courtesy phones at ATM’s, information kiosks, and emergency assistance pedestals. In this applica-
tion, when one handset is picked-up, the remote handset immediately begins ringing. When the remote
handset is picked-up, the speech path is completed. The end-to-end link supports voice, fax Gr.3 (2.4–14.4
kbps) with T.38 or fax- and modem bypass using a G.711 codec.
