NT8D14 Universal Trunk card

Figure 137
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.
