VFC rates are not the same, but follow the same concept. For detailed data on what the %Q value is, please download the file %L_&_%Q.TXT nnn=0 to 7 current signal quality excellent (higher rate may be used) nnn=8 to 20 current signal good (best carrier rate for line condition) nnn=21 to 30 current signal poor (lower carrier rate should be used) nnn=31 to 127 signal very bad (or gone), try forcing a lower rate NOTE: Modem uses 8 and 20 as rate renegotiation watermarks. %Q1 Connection Stats On V.32/V.32bis Connections these items are reported: EQM (Same as %Q) RX Level (Same as %L) TX Level (Current TX level in dBm) On V.FC & 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 as per V34 DSP specs. and ITU V.34 specs.) On V.34 Connections these items are also reported: 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 *Zn Change Dialing Codes (Used in countries like NORWAY that support two methods of pulse dialing.) *Z0 Does nothing, provided for backwards compatibility *Z1 Does nothing, provided for backwards compatibility +GMI Manufacturer ID +GMM Model ID +GMR ROM Code ID +MS= Configures the modulation(s), and rate(s) currently supported Syntax: +MS=,,, {Any values omitted remain at the current setting}.

To return to "Default" USA mode of full V34,VFC,V32bis, V22bis, Bell 212, and Bell 103 (assuming B1 is set) the user can enter just "+MS=11,,300, " however an input of "+MS=11,1,300,28800 " would give the same result. specifies the PREFERRED modulation as per the list below.

When this mode is active the modem listens to the answer signal from the remote modem. If both ANSam (V.34 support) and PNID (VFC) are heard, the Supra attempts VFC hand- shake. The PNID tone is at a lower frequency and strength then the ANSam tone, so it is possible for line impair- ments to mask the PNID tone, but allow the ANSam tone to be heard clearly. Such a condition would cause the Supra to attempt V.34 handshake due to not detecting the PNID tone.) S190 Minimum "GOOD" EQM (see %Q) Time (10-255 seconds) (60 default) V32,V32B,VFC,& V34 connections are affected.

(Affects %E2 / %G1 setting) S191 EQM Automatic Rate Adaption Bias (0-255, Zero Bias 128, Default 129) This adjustment affects V32,V32B,VFC,& V34 operation. The bias offset is summed with the EQM(%Q) reading to determine the carrier rate to select during initial TRAIN and RE-TRAINS (Rate Renegotiation (Fall Back/Forward) & %Q reading are NOT affected by the S191 setting) -Positive bias (values above 128) tends to DECREASE the initial carrier rate for a given connection. -Negative bias (values below 128) tends to INCREASE the initial carrier rate for a given connection.

SCn=n Telephone Signal Cadence Settings (Defaults change with country code) Each register "pair" holds the value for each setting. To set a value, divide the setting by 256. The integer value goes in the second (high byte) register, while the remainder (low byte) goes in the first. (A setting of 516 for the Phase 1 Minimum BUSY ON Time period would convert to 2 with a of remainder 4, and could be set by sending AT SC0=4 SC1=2 to the modem.) Settings are in 1/100ths of a second. Entries are listed as follows Minimum ON Time (2 bytes), Maximum ON Time (2 bytes), Min. OFF Time (2 bytes), Max. OFF Time (2 bytes), Number of valid singal cycles to occur before the signal is accepted as valid (1 byte). Some countries codes specify a two PHASE cadence pattern (On-Off in one pattern followed by a different On-Off pattern) for some singals, and in such cases, the "PHASE 2" entries would have NON-ZERO values (the US country code setting only supports single PHASE cadence patterns or patterns that just repeat the same On-Off pattern over and over.) (Listed default values are for the United States values) SC(0-8) PHASE 1 BUSY Minimum ON Time = 42 ( SC0=42 SC1=0 ) Maximum ON Time = 58 ( SC2=58 SC3=0 ) Minimum OFF Time = 42 ( SC4=42 SC5=0 ) Maximum OFF Time = 58 ( SC6=58 SC7=0 ) Number of Cycles = 4 ( SC8=4 ) (In the US SC0=22 & SC4=22 allows CONGESTION ("FAST" BUSY signals to be detected as a BUSY signal.)
