Features and Services
Conference
Toll Loss Plan is not supported when a conference is in progress. When a
local party connecting to a toll call makes a conference call, the pad levels on
the ONS line card are switched back to their original (non-toll call) values.
Then, the existing Conference algorithm takes care of the necessary pad
switching. This would not alter the existing conference call in terms of loss
levels.
When a conference call joins in a toll call, the Toll Loss Plan is not effective.
When a conference call involving a toll call becomes a two-party call, the Toll
Loss Plan is applied on the set and DTI2 trunk.
The conference pad switching algorithm is not changed for the Toll Loss
Plan, since the 7 db requirement does not apply to a Conference call.
Digitone Receiver Pads
When a Digitone Receiver (DTR) is connected to the DTI2 call (receive
only), the pad value to be used on the DTI2 pack is defined in overlay 73.
There is no interaction with this since the Toll Loss Plan is only supported on
a DTI2 trunk with MFC signaling.
Multifrequency Compelled Signaling Pads
There is no interaction with this operation, since the Toll pad switching is
only performed when the call is established and the Multifrequency
Compelled signaling has terminated.
Multi-Party Operations
When a user toggles between one party and another, the Toll Loss Plan is
inserted on the active call if it is a toll call. If the user toggles to a non-toll call,
the Toll Loss Plan is removed.
Feature packaging
The China Toll (CHTL) package 292 must be provisioned to activate this
feature.
