Mediant 500L Gateway & E-SBC
Parameter Description

To configure the device to support several ISDNIBehavior
features, enter a su
mmation 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

[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.
 [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 specification (default
behavior).
Note: When using the ini file to configure the device to support
several ISDNGeneralCCBehavior features, add the individual
feature values. For example, to support both [16] and [32]
features, set ISDNGeneralCCBehavior = 48 (i.e., 16 + 32).
