Important Notes:
1.
If you are looking to connect at a bit rate of 256 kbps it is better to use
MP2 Stereo
than
MP2 J-Stereo
because 128 kbps per channel is
adequate for high quality MP2 Stereo connections.
2.
The connection wizard is the safest way to configure connections. This is
because in the main connection menu via [Menu] > [Configuration] >
[ISDN/IP/X.21], all connection bit rates are displayed for selection.
Whereas in the connection wizard only relevant algorithm and sample
rate settings are available in order to optimize the quality of connections.
