sessionStatusTxStartDataRate
1.3.6.1.4.1.2637.2.2.101.1.39
The transmit DCE data rate for this session. In the
case of modem sessions, this will be the DCE rate
reported as a result of initial modem negotiation, and
may not track rate chanes during the call. For ISDN
sessions, this will be the actual data service rate of
the call. For Frame Relay sessions, this will be the
nominal speed of the Frame Relay Physical Interface,
even though multiple sessions may be sharing that
Physical Interface. For other sessions, this will be
the nominal speed of the physical interface. In no
case should this be interepreted as a
Quality-of-Service guarantee, or as the current line
utilization or effective bandwidth on the interface.
Note also that in the case of PPP multilink, this
specifies the rate of only this link in the bundle,
and not the aggregate rate of all links in the
bundle.
