Permit Mismatch
This option allows the EIA interface to operate at a rate different than that agreed to in the data
module handshake. (The data module handshake is always the highest compatible rate as
determined by the reported speed option of each data module.) Permit Mismatch eliminates the
need to change the DTE/DLC speed every time a call is placed to/from an endpoint operating at
a different speed. When this option is enabled, the DLC reports the highest optioned speed and
all the lower speeds (or the previously selected autoadjust speed) during the handshake
process.

usage of this type transmission results in loss of data. Whenever this option is
enabled, the DTE must match the highest speed selected for the associated DLC
port.
This option is intended to be used by a DTE device operating locally at a higher baud rate than
that of its far-end connection but transmitting relatively low amounts of data (for example, a user
typing at a terminal). Also, this option can be selected whether or not Keyboard Dialing is
selected.

The Low speed setting is not reported as an available speed when the Permit
