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 (–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
Level (–dBm)
Upstream transmit signal power.
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.
