ABSTRACT:
A maintenance method for a subscriber line of a B-NT in an ATM PVC switching system which is capable of more expanding a maintenance range of an OAM cell loopback function disclosed in the article 2. The method includes the steps of a first step in which a loopback OAM cell is transmitted to a B-NT when the ATM PVC switching system receives a request of a state information of subscriber links of a B-NT from an operator, or a loopback operation timer becomes time-out, a second step in which the B-NT, which receives a loopback OAM cell from the ATM PVC switching system, carries the statement information of subscriber lines of B-NT apparatus on a loopback OAM cell and then transmits the information to the ATM PVC switching system, and a third step in which the ATM PVC switching system, which receives a loopback OAM cell from the B-NT apparatus, stores a state information of subscriber lines into a state management table, reports a state information of subscriber lines to the system operator.
