Flexible Trunk to Trunk Connections Page 1547 of 3156

Features and Services

• B can conference Trunk Routes 1 and 2 and then disconnect. In this case,

Trunk Routes 1 and 2 remain connected, as TBAR does not bar the

connection between the two trunks.

• B cannot complete Transfer or Conference from Trunk Routes 1 or 2 to

Trunk Routes 3 or 4, as these trunk routes are barred by TBAR.

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 B is set to Flexible Trunk to Trunk Connections Restricted

(FTTR), the following is true:

• B cannot complete Transfer or Conference with Trunk Routes 1 and 2,

even though the connectivity between the trunks is allowed by TBAR.

This Class of Service functions as though the two trunks are blocked by

the Trunk Barring feature.

• B cannot complete Transfer or Conference from Trunk Routes 1 and 2 to

Trunk Routes 3 or 4, as these trunks are barred by TBAR.
