The power dissipation on the NPN bipolar transistor
driving the RING terminal can become large and may
require a higher power rating device. The non-tracking
mode of operation is required by specific terminal
equipment that, in order to initiate certain data
transmission modes, goes briefly on-hook to measure
the line voltage to determine whether there is any other
off-hook terminal equipment on the same line.
TRACK = 0 mode is desired since the regulator output
voltage has long settling time constants (on the order of
tens of milliseconds) and cannot change rapidly for
TRACK = 1 mode. Therefore, the brief on-hook voltage
measurement would yield approximately the same
voltage as the off-hook line voltage and cause the
terminal equipment to incorrectly sense another off-
hook terminal.

Note: The ProSLIC uses registers that are both directly and indirectly mapped. A “direct” register is one that is mapped
directly. An “indirect” register is one that is accessed using the indirect access registers (direct registers 28 through
31).
