This attribute counts the total number of frames retransmitted by the
IWF V.42 entity in a data call. The V.42 retransmits the same frame
when the associated T401 acknowledgment timer time-outs or when
a Reject (REJ) supervisory frame has been received from the Public
Switched Telephone Network (PSTN) modem. The counter wraps
when it exceeds the maximum value.
