Operating Procedure (cont’d)
5. Station A hangs up (Note 3); Stations B and C are connected with each other.
Note 3:
If Station A switch hook flashes instead of hanging up, a three-way connection is set up.
Service Conditions
1. When TRUNK-TO-TRUNK CONNECTION [T-10] is provided, an incoming or outgoing network or TIE
Line call may be transferred to an outgoing network trunk, provided that the trunk is ground-start. The user
who transfers the call gives line control to the two remaining parties upon hanging up. Therefore, if the
trunk is loop-start, CALL TRANSFER-ALL CALLS - CCIS from trunk-to-trunk will not function.
