Feature description
The China – Toll Call Loss Plan feature provides the requirement of 7 dB loss
for 2.0 Mbps Digital Trunk Interface (DTI2) toll calls from a Meridian 1,
acting as a Class 5 (C5) office. It is only applicable for a DTI2 trunk
connection using MFC signaling to an analog (500/2500 type) telephone.
Feature specific losses on the DTI2 card and 500/2500 line card are provided
if the call is recognized as a toll call and the local party is using an analog
(500/2500 type) telephone. The loss levels for toll calls are configured in LD
73 by using the TOLT and TOLL prompts.
With this feature, when a toll condition is detected, loss levels are sent to the
ONS line card. When the call is terminated, the original loss levels are sent to
the ONS line card.
