Feature description
This feature permits the Meridian 1 to detect disconnect and answer
supervision, when provided by the Public Switched Telephone Network
(PSTN), for outgoing Central Office (CO), FEX, or WATS loop-start trunks.
Answer and disconnect supervision signals, provided by the PSTN and
subsequently detected by the Meridian 1, reverse the battery polarity on the
tip and ring leads of the trunk (reverse-battery signaling).
Polarity Sensitive Packs (PSPs) or Polarity Insensitive Packs (PIPs) are
identified in overlay14.
This feature has the following options:
