Off-Premises Extensions (OPX)
Off-premises extensions are remote single-line DTMF sets that are connected to the Inter-Tel
system through telephone company OPX circuits (or customer-provided circuits).
Off-premises station users gain access to the features by hookflashing (pressing and releasing
the hookswitch quickly) and entering feature codes.
Some telephone company off-premises extension (OPX) networks do not recognize certain sin-
gle-line set ring cadences used in the system. This incompatibility results in an inability to pro-
vide certain ring signals to off-premises extensions. Because of this, the system is equipped
with a station option (Extended Ring Cadences) which allows the ring cadences be altered for
individual single-line circuits.
