%E n
%L
Line Quality Monitor
n = 0, 1, or 2
2
Controls whether or not the modem will automatically monitor the line quality and request
a retrain ( %E1 ) or fall back to a lower speed when line quality is insufficient and fall
forward to a faster speed when line quality is sufficient ( %E2 ).
%E0 Disables line quality monitor and auto-retrain.
%E1 Enables line quality monitor and auto-retrain.
%E2 Enables line quality monitor and fallback/fall forward.
Line Signal Level
None
None
% L Returns a value that indicates the received signal level in dBm. This value is a direct
indication (DAA-dependent) of the receive level at the MDP, not at the telephone line
connector. Examples: 009 = -9 dBm, 043 = -43 dBm, and so on.

Description:
%Q Line Signal Quality
None
None
% Q reports line signal quality (DAA-dependent) as a three-digit number. Returns the
higher order byte of the EQM value. Based on the EQM value, retrain or fallback/fall
forward may be initiated if enabled by %E1 or %E2 .

PCM Code Selection
n = 0 or 1
0
Specifies the PCM code type for 56K modulation. Note, however, that the modem
automatically selects the code type if the server sends the proper ID.
%U0 Selects μ-Law coding—used in North America and Japan.
%U1 Selects A-Law coding—used outside North America and Japan.
Note: See also the +MS= command.
Maximum MNP Block Size
Note: For use with MT5600BA and MT5600BR only.
n= 0, 1, 2, or 3
1
\A0 64-character maximum block size.
\A1 128-character maximum block size.
\A2 192-character maximum block size.
\A3 256-character maximum block size.
Transmit Break
n = 0–9 in 100 ms units
3
In non-error-correction mode only, sends a break signal of the specified length to a remote
modem. Works in conjunction with the \K command.
