Disconnect supervision
The Lineside T1 card supports far-end disconnect supervision by opening the tip side toward
the terminal equipment upon the system's detecting a disconnect signal from the far-end on
an established call. The Supervised Analog Line feature (SAL) must be configured in LD 10
for each Lineside T1 port. At the prompt FTR, respond:
OSP <CR>
and against FTR respond:
ISP <CR>
The Lineside T1 card treats OSP and ISP for both originating and terminating calls as hook
flash disconnect supervision, also known as cut-off disconnect. Originating calls are outgoing
from the terminal equipment. Terminating calls are incoming to the terminal equipment. The
Lineside T1 card does not support battery reversal answer and disconnect supervision on
originating calls.
