BIT SWITCHES
SM 2-5 A265/A267
Bit Switch 12 (Dch. Layer 3)
No. FUNCTION COMMENTS
0-7
Not used Do not change the factory settings.
Bit Switch 13: D channel layer 3 (Attachment IE in S: SETUP)
No. FUNCTION COMMENTS
0-1
Not used Do not change the factory settings.
2
Attachment of calling ID
0:
No
1:
Yes
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.
3
Attachment of the Lower
Layer Capabilities
0:
No
1:
Yes
This bit determines whether Lower Layer
Capabilities are informed in the [SETUP] signal.
Keep this bit at 0 in most cases.
4
Attachment of the Higher
Layer Capabilities
0:
Yes
1:
No
This bit determines whether Higher Layer
Capabilities are informed in the [SETUP] signal.
Keep this bit at 0 in most cases.
5
Attachment of channel
information element (L3
CONN)
0:
No
1:
Yes
This is normally fixed at 0.
6
Attachment of the Higher
Layer Capabilities for ISDN
G3
0:
Refer to bit 4
1:
Not attached
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.
7
Not used Do not change the factory setting.
