Loop powered
Description
The LH1465 ISDN dc Termination IC is used on
2-wire digital subscriber lines at the NT1. The device
provides a polarity-insensitive dc termination for the
loop sealing current and a recognizable signature for
metallic loop termination (MLT). The LH1465 IC con-
sists of two functional blocks. The first provides the
electronic inductor and silicon-controlled rectifier por-
tion of the dc termination, while the second drives the
LED of a 6N139 optoisolator. The LH1465 is the only
existing chip that provides integration of the dc termi-
nation and MLT required in North American ISDN ter-
minal equipment.
