
[67108864] NS ACCEPT ANY CAUSE = Accept any Q.850
cause from ISDN.
Note: This value is applicable only to Euro ISDN.

[1073741824] NS QSI ENCODE INTEGER = If this bit is set,
INTEGER ASN.1 type is used in operator coding (compliant to
new ECMA standards); otherwise, OBJECT IDENTIFIER ASN.1
type is used.
Note: This value is applicable only to QSIG.

[2147483648] NS 5ESS NATIONAL = Use the National mode of
AT&T 5ESS for B-channel maintenance.
Note: To configure the device to support several ISDNIBehavior
features, enter a summation of the individual feature values. For
example, to support both [512] and [2048] features, set
ISDNIBehavior = 2560 (i.e., 512 + 2048).
Same as the description for parameter ISDNIBehavior, but for a
specific trunk ID.
Bit-field used to determine several general CC behavior options.
To select the options, click the arrow button, and then for each
required option, select 1 to enable. The default is 0 (i.e., disable).

[2] = data calls with interworking indication use 64 kbps B-
channels (physical only).

[8] REVERSE CHAN ALLOC ALGO = Channel ID allocation
algorithm.

[16] = The device clears down the call if it receives a NOTIFY
message specifying 'User-Suspended'. A NOTIFY (User-
Suspended) message is used by some networks (e.g., in Italy or
Denmark) to indicate that the remote user has cleared the call,
especially in the case of a long distance voice call.

[32] CHAN ID 16 ALLOWED = Applies only to ETSI E1 lines
(30B+D). Enables handling the differences between the newer
QSIG standard (ETS 300-172) and other ETSI-based standards
(ETS 300-102 and ETS 300-403) in the conversion of B-channel
ID values into timeslot values:
1) In 'regular ETSI' standards, the timeslot is identical to the B-
channel ID value, and the range for both is 1 to 15 and 17 to 31.
The D-channel is identified as channel-id #16 and carried into
the timeslot #16.
2) In newer QSIG standards, the channel-id range is 1 to 30, but
the timeslot range is still 1 to 15 and 17 to 31. The D-channel is
not identified as channel-id #16, but is still carried into the
timeslot #16.
When this bit is set, the channel ID #16 is considered as a valid
B-channel ID, but timeslot values are converted to reflect the
range 1 to 15 and 17 to 31. This is the new QSIG mode of
operation. When this bit is not set (default), the channel_id #16
is not allowed, as for all ETSI-like standards.

[64] USE T1 PRI = PRI interface type is forced to T1.

[128] USE E1 PRI = PRI interface type is forced to E1.

[256] START WITH B CHAN OOS = B-channels start in the
Out-Of-Service state (OOS).

[512] CHAN ALLOC LOWEST = CC allocates B-channels
