%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)
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:
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

Result code syntax is as follows:
DATE=MMDD (where MM is month number 01-12 & DD is day 01-31)
TIME=HHMM (where HH is hour 00-23 & MM is minute 00-59)
"Single Page Mode"
NMBR= number code or statement*
* The NUMBER CODE is normally either the subscriber's area code,
local exchange, and subscriber loop number, OR a code unique to
that individual subscriber. STATEMENTs are used for calls from
non Caller ID Areas and subscribers requesting no display.
NAME= listed subscriber name <this is an option not always supported>
"Multiple Page Mode"
MESG= formatted number string * **
* Here is an example string: 030A35303339363732343030
The string uses this code: CCLL#0#1#2#3#4#5#6#7#8#9
CC (03) is the code meaning this is "Multiple Page" Caller ID
LL is the hexadecimal length of the data in the string.
(in this case 0A hex - 10 decimal)
#n's are the ASCII digits dialed (in hexadecimal)
A neat trick to convert these to decimal is to note that
the first digit is always a number "3" and the second digit
is the decimal number dialed, so the formatted string:
030A35303339363732343030 converts directly to 5039672400
** At the time of this printing, conversion of "Multiple Page"
Caller ID string coversion is not supported in the modem,
so the data is displayed in the raw hexadecimal format.
Special Codes: Out of Area (No CID Data Available)
DATE = {current date}
TIME = {current time}
NMBR = O
MESG = 08014F
Private (CID Data Available, But BLOCKED)

-SDR? Reports the current Distinctive Ring Configuration.
-SDR=n Distinctive Ring Configuration (0-7, Default 0)
Each bit set high in this register enables the corresponding
Distinctive Ring detection and result code. All bits disabled
sets normal ring detection only. (Saved in NVRAM via &W)
Bit (Decimal Value)
0 (1) Enables Single rings and reports these as RING 1
2.0s on, 4.0s off (normal ring)
1 (2) Enables Double rings and reports these as RING 2
0.8s on, 0.4s off, 0.8s on, 0.4s off
2 (4) Enables Triple rings and reports these as RING 3
0.4s on, 0.2s off, 0.4s on, 0.2s off
0.8s on, 4.0s off
NOTES: The current code doesn't discriminate between short (0.4
second) and long (0.8 second) ring pulses. So two of the
Bellcore standard ring patterns (RING 3 & RING 4) will be
reported as RING3 (If RING 3 detections is active).

<automode> 0 (Disable) Limits the modem to the PREFERRED <mod>
protocol within the specified <maximum rate>
and <minimum rate> range.
1 (Enable - Default) Allows the modem to "fall back"
to other protols within the specified <maximum rate>
and <minimum rate> range for which standard automode
procedures exist using V8 or V32 Annex A.
Exampe: Failed V34 connection attempts can automode
to VFC or lesser protocols, but a Bell 103 connection
attempt cannot automode to V23.
<minimum rate> sets the lowest carrier rate that may be used.
(Default 300 bps)
<maximum rate> sets the maximum carrier rate that may be used.
(Default 33600 bps) Setting a non-zero value in the S37
command adjusts the +MS rate commands as well.

answer signal from the remote modem. If
both ANSam (V.34 support) and PNID (VFC)
are heard, the modem 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 modem to
attempt V.34 handshake due to not
detecting the PNID tone.)
S190 Minimum "GOOD" EQM (see %Q) Time (10-255 seconds) (20 default)
V32,V32B,VFC,& V34 connections are affected. S190 sets the minimum

S191 EQM Automatic Rate Adaption Bias (0-255, Zero Bias 128, Default 128)
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)

Higher symbol rates have a better signal to noise ratio on a
given line than the lower rates. But the higher rates require
more bandwidth than the lower ones. When making a connection
the highest symbol rate that will run over the available
bandwidth is used.

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)
