MIB Object Name
Description
mdmStatRetrainReqReceived
The number of retrain requested received by
the modem from the remote modem for this
call.
mdmStatRRNReqSent
The number of rate renegotiation requests
initiated by this modem. The RRN request
is initiated because of changes in the line
quality (good or bad). Renegotiation is done
typically to make a quick change in speed
(up or down.)
mdmStatRRNReqReceived
The number of rate renegotiation requests
initiated by the remote modem. The RRN
request is initiated because of changes in
the line quality (good or bad).
Renegotiation is done typically to make a
quick change in speed (up or down.)
mdmStatRoundTripDelay
Round trip delay, in milliseconds, for this
call.
mdmStatFarEndEchoFreq
The far end echo frequency offset. This
object along with the object
mdmStatRoundTripDelay, gives the echo
characteristics of the call.
mdmStatFarEndEchoLevel
Far end echo level in decibels (db). The
number represents the negative decibels.
mdmStatChanFreqOffset
Channel frequency offset in Hertz.
mdmStatOscFreqOffset
Oscillator frequency offset in Parts Per
Million (PPM).
mdmStatSNR
Signal to noise ratio expressed in decibels
(db). (0 db to -80 db) An SNR of 0 db is the
worst quality, while -80 db is the best.
Typical values should be -32 db to -38 db.
