L<value>—Speaker Volume
Use this command to set the speaker volume setting when the speaker is on.
Result codes:
• OK if <value> = 0—3.
ERROR if <value> ≠ 0—3.
•
Table 11. L<value> Commands
Command
L0 Low volume.
L1 Low volume.
L2 Medium volume (default).
L3 High volume.
The received signal power, although labeled with units of –dBm, is only a
relative measure for comparing calls to/from different locations. This value
is valid only during a call.
Upstream transmit signal power.
Round trip delay in milliseconds.
Echo levels are valid for V.34 only.
Echo levels are valid for V.34 only.
Number of LAPM frames sent upstream during this call. Count wraps
around at 65535.
Number of LAPM frames received by the client during this call. Count wraps
around at 65535.
Number of retrains or rate renegotiations requested by the modem.
Number of retrains or rate renegotiations requested by remote modem.
Number of rate renegotiations requested by the local modem.
Number of rate renegotiations requested by the remote modem.
Reason for call ending. Only valid after call ends. Result codes:
• 0 = local modem command: ATH, DTR drop.
• 1 = remote modem: cleardown, loss of signal.
• 2 = no answer, busy, etc.
• 3 = training failure V.92, V.90, or V.34.
• 4 = protocol failure if required by \N4, for example.
For PCM connection only, a hexadecimal 6-bit pattern of T1 frames with
robbed-bit signaling.
For PCM connection only, the downstream digital loss.
Shows the last S pointer when the modem is expected to go to PCM mode.
