Page 1026 of 3156 China – Toll Call Loss Plan
553-3001-306 Standard 10.00 January 2002
The outgoing toll call is recognized by defining the toll digits as a Special
Service List number in overlay 18 and specifying it in the DTI2 Route Data
Block. For incoming calls, the toll status is provided by the Multifrequency
Compelled (MFC) signaling. When the toll status is determined, the
appropriate pad values are used on the DTI2 card and 500/2500 line card.
Operating parameters
The Toll Loss Plan is only supported when a pure Intelligent Peripheral
Equipment (IPE) Loss Plan for China is used. Existing pad levels for DTI2
toll calls with Hybrid Loss Plan for China are unchanged.
This feature is only supported for a Class 5 Meridian 1 switch.
The Toll Loss Plan is only supported on DTI2 MFC trunks.
If an initialization occurs, the toll call stays connected, but the toll status is
lost. The pad levels are reinserted as if it is for a non-toll call.
The Toll Loss Plan is not supported when a conference call is in progress.
China specific IPE 500/2500, DTI2, and MFC line cards are required.
Feature interactions
Call Diversion (Call Transfer, Call Forward All Calls, Call Forward
Busy, Call Forward, Internal Calls, Call Forward No Answer,
Hunting)
Toll pad switching is also provided after call diversion has been completed.
When the toll call is diverted, the diverted party’s pad level is switched back
to its original value (unless it is an OPS station using dynamic switching). The
Toll Loss Plan is applied again for the new call as if it is a direct call. For Call
Transfer, it is provided after the transferring party completes the transfer and
drops out. For Call Forward or Hunting, it is provided when the forwarding
or hunting call is answered.
