Disallow Trunk-to-Trunk Transfer
Trunk-to-trunk transfer is a feature that allows an incoming trunk call to be
transferred to an outgoing trunk call. If set to
yes, the station can hang up and
leave the two trunks still connected. If set to no, then the trunks are disconnected
as soon as the station hangs up.
For DEFINITY G1, G3V1, G3V2, and System 75:
 Use change system-parameters feature to display the Features-Related
System Parameters screen.
 Enter n in the Trunk-to-Trunk Transfer field.
For DEFINITY G2 and System 85:
 Set PROC275 WORD4 FIELD3 to 0 to disable trunk-to-trunk transfer.
For DEFINITY G3V3 and later releases:
 Use change system-parameters to display the Features-Related System
Parameters screen.
 Enter the following in the Trunk-to-Trunk Transfer field, as appropriate:
— Enter
a (all) to allow all trunk-to-trunk transfers.
— Enter
r to restrict all public trunks (CO, WATS, FX, DID, and CPE).
— Enter
n (none) to restrict all trunks from being transferred except
DCS and CAS.
NOTE:
Even if Trunk-to-Trunk Transfer is disallowed, the START 9 RELEASE
sequence will supply a dial-tone to the caller, enabling trunk-to-trunk transfer
to proceed.
