CONSTITUTION:When the operator is intervened to the office line trunk COT of hold condition and the hold RE button corresponding to the RE lamp flickered on the relay board ATT is depressed, the marker MKR is started from the seat register PR. When the marker MKR selects the trunk COT of hold state after the extension connection operation, the PK relay of the marker MKR is operated and the operator can automatically be intervened to the extension side. When the trunk COT in hold state before the extension connection operation is selected, the PK relay of the marker MKR is inoperative and the operator can automatically be interrupted to the office line side. |
