This attribute specifies the bandwidth this End Point will request
when setting up a transfer connection which the transport in the
forward (from the originating to the terminating End Point)
direction.
A conservative value would be the sum of the committed
information rates (CIRs) of all individual Frame Relay DLCIs
multiplexed on the transport connection.
For ATM connections, the value is converted to an equivalent Peak
Cell Rate (PCR01) for all cells with Cell Loss Priority (CLP), CLP
= 0 and CLP = 1.
Note that the conversion to an equivalent cell rate for ATM
connections may result in some wasted bandwidth depending on the
average frame size to cell ratio.
