This attribute specifies whether the Frame Relay LMI Active Bit
(A-bit) has a bearing on the transfer of user data across this Frame
Relay interface for both directions of traffic flow.
When this attribute is set to yes, the A-bit status of a user DLCI
connection does not affect data transfer.
When this attribute is set to no, data received from the local
interface will be discarded if an A-bit =0 condition exists towards
the local user. Data being sent to the local interface is discarded if
an A-bit = 0 condition exists towards the subnet.
