Referring to Figure 44, when Flexible Trunk to Trunk Connections Options
is set to Trunk Barring Flexible Trunk to Trunk Connections (TBFT) and the
Class of Service of Set B is set to Flexible Trunk to Trunk Connections
Conditional (FTTC), the following is true:
• B cannot complete the Call Transfer from Trunk Route 1 to Trunk
Route 2
• B can complete the Supervised Conference with Trunk Routes 1 and 2.
If Set B drops out of this conference, Trunk Routes 1 and 2 are
disconnected.
• B cannot complete both Transfer and Conference from Trunk Routes 1
or 2 to Trunk Routes 3 or 4, as these trunks are barred by TBAR.
