SM
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.
Refer to Appendix C for more details.
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.
On the 5ESS network (USA), set it to 1.
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.
This bit depends on user requirements. If it is at 1,
communication will be halted if the other terminal has
not input the subaddress.
Refer to Appendix C for more details.
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 France and Germany (1TR6), also in
countries where the global call reference is used.
Do not change the factory settings.
