ATI11 Command Results
Table 3-8:
V.92, V.90, V.34, or V.32, depending on the type of connection negoti-
ated.
Initial upstream rate.
Initial downstream rate.
Current or final upstream rate.
Current or final downstream rate.
LAPM, MNP *, or none, depending on V.42 negotiation.
LAPM, MNP, or none, depending on V.42 negotiation.
Signal to noise ratio with implied negative. Higher values indicated better
conditions.
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.
Near echo levels only.
Far echo levels only.
Number of LAPM frames sent upstream during this call. Count wraps
around at 65535.
Number of REJ frames received at the analog client modem.
Number of LAPM frames received by the client during this call. Count
wraps around at 65535.
Number of frames received in error by the client.
Number of retrains or rate renegotiations requested by the modem.
Number of retrains or rate renegotiations requested by the remote
modem.
Reason for call ending. Only valid after call ends. Result codes are as fol-
lows: • 0 = local modem command: ATH, DTR drop. • 1 = remote modem:
cleardown, loss of signal. • 2 = no answer, busy, etc. • 3 = training failure
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.
