NEC Univerge SV9100 - Pre-Ringing Setup

Issue 4.0
SV9100 Programming Manual 2-21
Description
Use Program 10-08 : Pre-Ringing Setup to enable or disable pre-ringing for trunk calls. This sets how
a trunk initially rings a telephone. With pre-ringing, a burst of ringing occurs as soon as the trunk LED
flashes. The call then continues ringing with the normal ring cadence cycle. Without pre-ringing, the call
starts ringing only when the normal ring cadence cycle occurs. This may cause a ring delay, depending
on when call detection occurs in reference to the ring cycle.
Conditions
 Used with Analog Trunks only.
