G4 Internal Switch 13: D channel layer 3 (Attachment IE in S: SETUP)
No. FUNCTION COMMENTS
7 Condition for fallback from G4 to
G3
0: Refer to the CPS code setting
1: Fallback in response to any CPS
code
0: Fallback occurs when a CPS code is the
same as the CPS code settings specified
by G4 internal switches 17, 18, 1A, 1B, and
1C.
If you wish to enable fallback when any CPS
code is detected, set this bit to “1”.
This switch is effective in coping with fallback
problems where the CPS code does not
match those specified in the ITU-T
recommendation.
G4 Internal Switch 14: D channel layer 3 (Selection IE in S: SETUP)
No. FUNCTION COMMENTS
0 ISDN G3 information transfer
capability
0: 3.1 kHz audio
1: Speech
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.
1-2 Not used Do not change these settings.

Bit 4 3 Setting
0 0 Any
channel
0 1 B1 channel
1 0 B2 channel
1 1 Not used
Any channel: When this is informed to the
exchanger, the exchanger will select either B1
or B2.
5 Called ID mapping
0: Called party number
1: Keypad facility
0: Called ID is mapped to the called party
number.
1: Called ID is mapped to the keypad facility.
Note that the subaddress in not mapped.
On the 5ESS network (USA), set it to 1.
6 Numbering plan for the called party
number
0: Unknown
1: E.164
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.
7 Subaddress coding type
0: IA5 (NSAP)
1: BCD (ISO8348)
This is normally kept at 0. However, some
networks require this bit to be at 1.
