and received.
Possible choice: Interleave Only/Fast Only
* Interleave mode is used when transmission error correction is necessary due to a less
than ideal telephone line.
* Fast mode will result in faster transmission rate.
Rate Mode This specifies what form of transmission rate adaptation is configured on this port.
fixed – Connect over the fixed speed given by ‘Tx Rate’ field, the connection gets fail if
it can not reach the lengths and qualities of lines
adaptAtStartup – Connect over the range of speed given by ‘Tx Rate’ field, the
connection gets retrain due to varying qualities of lines.
adaptAtRuntime – Connect over the range of speed given by ‘Tx Rate’ field, the
connection is auto rearrange seamlessly due to varying qualities of lines.
