DBS-2.3/9.2-400
Inbound Ring Cycle Expansion Timer
Software Version: All Versions
Address: FF1 3# 16# (0-15)#
Description
If the incoming ring pattern for an extension (FF3 ExtPort# 39#) is set to
emulate CO ringing, an extension may sometimes receive a very short ring
burst when a trunk call begins ringing. This short ring burst occurs because
the DBS received only part of the first “on” burst (see Figure 1-2, previous
page) from the trunk.
To eliminate these short rings, this timer can be used to expand initial ring
bursts. For example, if the timer is set to 350 ms and the first ring burst only
lasts 50 ms, the first ring burst sent to the extension will be 350 ms. If the
first ring burst is over 350 ms, the timer is ignored and the DBS emulates the
initial CO ring.
