ATI3 = ROM revision code / Model name / Firmware build date ATI7 = DSP Model & Version Code AT\S = \S Report Active Configuration (Verbose) (Requires Optional Feature 146) AT%Q1 Connection Stats On V.32/V.32bis Connections these items are reported: EQM (Same as %Q) (Average over the last second) RX Level (Same as %L) TX Level (Current TX level in dBm) TX data rate = (now) min = max = RX data rate = (now) min = max = On VFC & V.34 Connections these items are also reported: Far Echo Delay (Round trip far end echo delay in mS.) Far Echo Level (Signal Strength of far echo in dBm.) Pre-Emphasis Filter (Filter in use to normalize the lines frequency response per ITU V.34 specs.) On V.34 Connections these items are also reported: Pre-Coding TX (0 no, 1 active) RX (0 no, 1 active) Shaping TX (0 no, 1 active) RX (0 no, 1 active) Non-linear encoding TX (0 no, 1 active) RX (0 no, 1 active) Trellis mapping Type in use (16-4D, 32-4D, 64-4D) SNR (Signal to Noise ratio measured during the line probe, in dB). Normalized Bandwidth (The -3dB roll off points after the pre- emphasis filter is applied. This is NOT the same as the usable audio band- width since the signal has been heavily processed prior to this measurement. This range determines the maximum symbol rate the line will support.) Symbol rate (Symbols per second on the connection) TX Carrier -If the symbol rate is below 3429 there are two available carrier frequencies. (A high carrier and a low carrier.) The actual frequency of the carriers varies with the symbol rate. "high" or "low" are the only items displayed. RX Carrier -Same as above on received carrier AT%Q2 Data Transfer Stats (Current call or last call) On ALL Connections these items are reported: Termination reason = (Same as S86) Transmitted Bytes = Received Bytes = On V.42 (LAPM) Connections these items are also reported: Transmitted I frames = Octets = Received I frames = Octets = Bad frames received = T401 resent I frames = SREJs received = Resent I frames = REJs received = Resent I frames = SREJs transmitted = REJs transmitted = SREJ =(enabled/disabled) Transmit window size = Receive window size = Transmit frame size = Receive frame size = On V.42bis (BTLZ) Connections these items are also reported: BTLZ dictionary size = BTLZ string length = Transmit Compression =(enabled/disabled) Receive Compression =(enabled/disabled) The %Q2 status screen now includes the number of octets transmitted and received in LAPM I frames. It also includes the number of I frames retransmitted due to SREJ and REJ frames being received and the number of I frames retransmitted due to timer T401 expiring. REJ frames cause the retransmission of an I frame and any I frames that were transmitted after that I frame. The number of I frames retransmitted due to REJ frames is usually more than the number of REJ frames received. SREJ frames cause the retransmission of a single I frame, any I frames transmitted after the rejected I frame are not retransmitted. The number of I frames retransmitted due to SREJ is usually equal to the number of SREJ received. The number of I frames retransmitted by REJ and SREJ frames may be lower than expected if acknowledgements of the requested I frame arrive after the receipt of the REJ/SREJ for that I frame and prior to the retransmission of the I frames. This may happen if I frames are retransmitted due to the expiration of T401 and a REJ/SREJ is received for the original transmission of the I frames. ==============================================================================
