Parameter Description
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 feat
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-
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
