Result Description
Last Connection
V.92, V.90, V.34, or V.32, depending on the type of connection negoti-
ated.
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.
Receive Frame Count
Number of LAPM frames received by the client during this call. Count
wraps around at 65535.
Receive Frame Error Count
Number of frames received in error by the client.
Retrain by Local Modem
Number of retrains or rate renegotiations requested by the modem.
Retrain by Remote Modem
Number of retrains or rate renegotiations requested by the remote
modem.
Call Termination Cause
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.
Robbed-Bit Signaling
For PCM connection only, a hexadecimal 6-bit pattern of T1 frames with
robbed-bit signaling.
Digital Loss (dB)
For PCM connection only, the downstream digital loss.
