mpanlDlciLoopbackState
mpanl Dlci Loopback State
This attribute has the value on when the DLCI is in loopback mode and off otherwise. This loopback command verbs start and stop are used to initiate and terminate the loopback mode for a DLCI. While loopbackState is on, an active A-bit signal will be reliably propagated across the subnet to the remote DLCI.
