This attribute indicates the current T1 timer negotiated by the Radio
Link Protocol (RLP), during Exchange Information (XID). This is
the period in milliseconds within which an acknowledgment of a
sent frame must be received. Once this timer expires, the
transmitting RLP entity shall assume that the frame was lost. The
value used for XID negotiations can be provisioned by component
GsmIwfRadioLinkProtocol attribute t1AckTimer.
