Parameter
Web: General Call Control Behavior
EMS: General CC Behavior
CLI: isdn-bits-cc-behavior
[ISDNGeneralCCBehavior]
Version 6.8
67. Configuration Parameters Reference
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.
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 starting from the lowest available B-channel id.

[1024] CHAN ALLOC HIGHEST = CC allocates B-
channels starting from the highest available B-channel id.

[16384] CC_TRANSPARENT_UUI bit: The UUI-protocol
implementation of CC is disabled allowing the application
to freely send UUI elements in any primitive, regardless
of the UUI-protocol requirements (UUI Implicit Service 1).
This allows more flexible application control on the UUI.
When this bit is not set (default behavior), CC implements
the UUI-protocol as specified in the ETS 300-403
standards for Implicit Service 1.

[65536] GTD5 TBCT = CC implements the VERIZON-
GTD-5 Switch variant of the TBCT Supplementary
Service, as specified in FSD 01-02-40AG Feature
Specification Document from Verizon. Otherwise, TBCT
is implemented as specified in GR-2865-CORE
