Used Bytes Per Cell
Rx Specifies the number of payload bytes to be expected in the cells received by the new
connection.
Remaining bytes are assumed to be padding bytes and are therefore discarded.
Tx Specifies the number of payload bytes to be inserted in the cells before transmitting it.
After the specified number of payload is collected, the remaining bytes in the cell are
filled with padding, and the cell is immediately transmitted toward the network.
This parameter enables the user to reduce the delay caused by the cell filling in
applications that cannot tolerate long delays.
The following fields are disabled if AAL1 Type is not DBCES.
