Tips -
Find out if your Norstar system is connected to a
central office (CO) with digital network loss treatment
(ISDN I/F levels) or analog network loss treatment
(PSTN I/F levels) by checking with your telecommunications
service provider.
The ISDN setting requires digital access lines (DAL) that have
digital network loss treatment. On a DAL network, it is the
PBX that administers the dB loss. DALs may have ISDN
signaling or digital (such as T1 and so on) signaling. To have
DAL network loss treatment on a line with digital signaling,
you must contact your service provider.
The PSTN setting requires analog access lines (AAL) that
have analog network loss treatment and digital signaling. On
an AAL network, the CO administers the dB loss.
