COMMENTS
Do not change the factory settings.
Normally, this bit should be at 0, because most
networks add the calling ID to the SETUP signal
to the receiver.
However, some networks may require the
machine to add this ID. Only in this case should
this bit be at 1.
This bit determines whether Lower Layer
Capabilities are informed in the [SETUP] signal.
Keep this bit at 0 in most cases.
This bit determines whether Higher Layer
Capabilities are informed in the [SETUP] signal.
Keep this bit at 0 in most cases.
This is normally fixed at 0.
This bit determines whether Higher Layer
Capabilities are informed in the [SETUP] signal
for ISDN G3 transmission. This switch is effective
in coping with communication problems with
some types of T/A and PBX which do not respond
to Higher Layer Capability "G3."
When this bit is set to 0, the setting depends on
the setting of bit 4.
Do not change the factory settings.
