
[134217728] NS_BRI_DL_ALWAYS_UP (0x08000000) = By
default, the BRI D-channel goes down if there are no active
calls. If this option is configured, the BRI D-channel is always
up and synchronized.

[536870912] = Alcatel coding for redirect number and display
name is accepted by the device.
Note: This option is applicable only to QSIG (and relevant for
specific Alcatel PBXs such as OXE).

[1073741824] 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 option is applicable only to QSIG.

[2147483648] 5ESS National Mode For Bch Maintenance =
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 the
parameter ISDNIBehavior is set to 2560 (i.e., 512 + 2048).

When configuring through the Web interface, to select the
options click the arrow button and then for each required
option select 1 to enable.

For BRI terminal endpoint identifier (TEI) configuration, instead
of using the ISDNIBehavior parameter, use the following
parameters: BriTEIConfigP2P_x, BriTEIConfigP2MP_x,
BriTEIAssignTrigger_x, and BriTEIRemoveTrigger_x.
[ISDNIBehavior_x] Same as the description for parameter ISDNIBehavior, but for a
specific trunk ID.
General Call Control Behavior
configure voip > interface e1-
t1|bri > isdn-bits-cc-behavior
[ISDNGeneralCCBehavior]
Bit-field for determining 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:

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.

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.
