Loop start call states - incoming call from CO/FX/WATS
The CS 1000 software provides the polarity-sensitive/polarity-insensitive
(PSP and PIP) packs feature for the accurate recording of outgoing call
duration for loop start and ground start operation. On trunks equipped with
far-end answer supervision, the PSP class of service is enabled in software
and causes call-duration recording in CDR records to begin only upon
receipt of answer supervision from the far-end. For trunks not equipped with
answer supervision, the PIP class of service is enabled and call-duration
recording begins immediately upon near-end trunk seizure. The PSP and
PIP classes of service are enabled in the Trunk Administration program
LD 14.
