Original channel probe MTA option

Miscellaneous mapping table MTA options:  (0 or 1)
RESTRICTED.

The  MTA option controls whether things  like    mapping table probes, when performed by the  conversion channel and any additional    channels, or the process channel or  hold channel,  use the original channel as the input channel name, or use the current source channel as the input channel name. For instance, this distinction can make a difference when applying both conversion and character set conversions to the same message. Conversions happen before character set conversion. So this option affects which channel name should appear in the channel-name clause of the     mapping probe, the original channel, or the current source channel (which will be the conversion channel at that point). The default is 0, meaning to use the current input channel name.
