cif L Loopback

1.3.6.1.4.1.9.9.9399.1.1.1.1.1

This object specifies the type of loopback to be established. This object is required in order to complete the creation of a row in this table. It cannot be modified when the cifLRowStatus is active(1). Possible values are : farEndLineLoopback(1): This loopback occurs at the CPE upon receiving a special code from the device which initiates the loopback. Upon receiving the loop activation request code, CPE enters a Line loop mode in which it returns the entire line back to the initiator. The CPE will continue to return the data back to the initiator until it receives a loopback deactivation request code. farEndPayloadLoopback(2): This loopback occurs at the CPE upon receiving a special code from the device which initiates the loopback. Upon receiving the loop activation request code, CPE enters a Payload loop mode in which it returns the Payload of the received data back to the initiator. The CPE will continue to return the data back to the initiator until it receives loopback deactivation request code. remoteLineLoopback(3): This loopback is established at the Near-end. In this loopback the entire line is looped back to the Far-end with a) bit-sequence integrity maintained, b) no change in framing, and c) no removal of bi- polar violations. remotePayloadLoopback(4): This loopback is established at the Near-end. In this loopback the signal that is returned to the Far-end consists of the payload of the received signal (with bit sequence integrity retained) and newly generated framing information. localLoopback(5): This is also known as metallic loopback. This loopback is used for checking the internal circuitry of the T3/E3, T1/E1 device. Only for physical lines.
