Appendix A AT Commands The following table describes each of the results listed for the ATI 11 command. ATI11 Command Results Result Description Last Connection V.90, V.34, or V.32, depending on the type of connection negotiated. Initial Transmit Carrier Initial upstream rate. Rate Initial Receive Carrier Rate Initial downstream rate. Final Transmit Carrier Rate Current or final upstream rate. Final Receive Carrier Rate Current or final downstream rate. Protocol Negotiation Result LAPM, MNP *, or none, depending on V.42 negotiation. Data Compression Result LAPM, MNP, or none, depending on V.42 negotiation. Estimated Signal/Noise Signal to noise ratio with implied negative. Higher Ratio values indicated better conditions. Receive Signal Power Level (-dBm) 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. Transmit Signal Power Upstream transmit signal power. Level (-dBm) Round Trip Delay (ms) Round trip delay in milliseconds. Near Echo Level (-dBm) Near echo levels only. Far Echo Level (-dBm) Far echo levels only. Transmit Frame Count Number of LAPM frames sent upstream during this call. Count wraps around at 65535. Transmit Frame Error Count Number of REJ frames received at the analog client modem. 33

Appendix A
AT Commands
33
The following table describes each of the results listed for the
ATI 11
command.
ATI11 Command Results
Result
Description
Last Connection
V.90, V.34, or V.32, depending on the type of
connection negotiated.
Initial Transmit Carrier
Rate
Initial upstream rate.
Initial Receive Carrier
Rate
Initial downstream rate.
Final Transmit Carrier
Rate
Current or final upstream rate.
Final Receive Carrier Rate Current or final downstream rate.
Protocol Negotiation
Result
LAPM, MNP *, or none, depending on V.42
negotiation.
Data Compression Result
LAPM, MNP, or none, depending on V.42
negotiation.
Estimated Signal/Noise
Ratio
Signal to noise ratio with implied negative. Higher
values indicated better conditions.
Receive Signal Power
Level (µdBm)
The received signal power, although labeled with
units of µdBm, is only a relative measure for
comparing calls to/from different locations. This
value is valid only during a call.
Transmit Signal Power
Level (µdBm)
Upstream transmit signal power.
Round Trip Delay (ms)
Round trip delay in milliseconds.
Near Echo Level (µdBm)
Near echo levels only.
Far Echo Level (µdBm)
Far echo levels only.
Transmit Frame Count
Number of LAPM frames sent upstream during
this call. Count wraps around at 65535.
Transmit Frame Error
Count
Number of REJ frames received at the analog
client modem.
