Description: This attribute indicates the state of V.42. Valid states are:

notActive, The V.42 link connection with the Public Switched Telephoned Network) PSTN modem is not established. None of the V.42 functions including the error detection, error correction, and flow control is provided to the data call. This is the initial state of V.42. disconnected, This means that the V42 link is disconnected. linksetup, The V.42 operation enters this state from the disconnected state after the V.42 sends to the PSTN modem a Set Asynchronous Balanced Mode Extended (SABME) frame in an attempt to establish the error control connection with the PSTN modem. frameReject, The V.42 operation enters into this state after it identifies an invalid frame sent by the peer and it sends back a frame reject (FRMR) frame to the peer. disconnectRequest, The V.42 operation enters into this state after it sends to the peer a disconnect (DISC) frame with the attempt to disconnect the V.42 error control link. informationTransfer, The V.42 enters into this state after it receives a UA (unnumbered acknowledgment) frame which the peer sent upon receipt of the SAMBE frame from IWF V.42. Once in this state, the V.42 can exchange data and supervisory information with its peer. waitingAck, The V.42 enters this state after it sends polling enquiry to its peer. The V.42 sends the polling enquiry when it receives a reject frame (REJ) from its peer or either its acknowledgment timer or inactivity timer timed out on the information frames sent out.
