COMMENTS
In tx mode, this determines the information
transfer capability informed in the [SETUP]
message.
In rx mode, this determines the information
transfer capability that the machine can use to
receive a call.
Set this bit to 1 if the ISDN does not support 3.1
kHz audio. This bit is only used in the USA and
the UK.
Do not change the factory settings.
Any channel: When this is informed to the
exchanger, the exchanger will select either B1 or
B2.
0: Called ID is mapped to the called party
number.
1: Called ID is mapped to the keypad facility.
E.164: This may be used in Sweden if an AXE10
exchanger is fitted with old software, and in
Australia.
Unknown: This is the normal setting.
This is normally kept at 0. However, some
networks require this bit to be at 1.
COMMENTS
This bit depends on user requirements. If it is at 1,
communication will be halted if the other terminal
has not input the subaddress.
Do not change the factory settings
Global call reference means 'call reference value
= 0'. This bit determines how to deal with such an
incoming call if received from the network.
Keep this bit at 1 in Germany (1TR6), also in
countries where the global call reference is used.
Do not change the factory settings.
