This structure contains the configuration structure for Layer 3 of an ISDN
common channel signaling trunk.
- AlertMode
- Contains the configuration parameters for outgoing alert messages. See SL_ISDN_ALERT_MODE for a description.
- fBChanServiceMessagesEnabled
-
- TRUE
- Specifies that an ISDN signaling process is required to send a B-Channel
service message before a signaling channel is enabled or disabled in non-facility
associated signaling configuration (NFAS) mode.
- FALSE
- Specifies that an ISDN signaling process is not required to send a B-Channel
service message before a signaling channel is enabled or disabled in non-facility
associated signaling configuration (NFAS) mode.
- fDChanServiceMessagesEnabled
-
- TRUE
- Specifies that an ISDN signaling process is required to use D-Channel
service messages before the signaling channel is used for other traffic in
non-facility associated signaling configuration (NFAS) mode. This allows the
system to control the primary and backup signaling channels.
- FALSE
- Specifies that an ISDN signaling process is not required to use D-Channel
service messages before the signaling channel is used for other traffic in
non-facility associated signaling configuration (NFAS) mode.
- fSendRestartOnChannelEnable
-
- TRUE
- Defines that an ISDN signaling process should send the RESTART message
to the network when the channels are enabled by the Blueworx Voice Response system manager.
(See ITU-T Recommendation Q.931, 1988 section 5.5.)
- FALSE
- Defines that an ISDN signaling process should not send the RESTART message
to the network when the channels are enabled by the Blueworx Voice Response system manager.
(See ITU-T Recommendation Q.931, 1988 section 5.5.)
- fUseT309
-
- TRUE
- Defines that timer T309 should be used (see ITU-T Recommendation Q.931).

3 Actions Resulting from a Malfunctioning Data Link of Bellcore TR-NWT-001268 ISDN Primary Rate Interface Call Control Switching and signalingGeneric
Requirements for Class II Equipment.
- FALSE
- Defines that timer T309 should be not be used (see ITU-T Recommendation
Q.931).
- iNfasGroupTrunkIds
- Contains a one-indexed array of NFAS trunk IDs (such that array element
1 corresponds to the ID of trunk 1)
- iNfasPrimarySignallingTrunk
- Specifies the primary trunk for this non-facility associated signaling
configuration (NFAS) group.
- iNfasBackupSignallingTrunk
- Specifies the backup trunk for this non-facility associated signaling
configuration (NFAS) group.
- iMaintenanceMessageProtocolDiscriminator
- Specifies the protocol discriminator that the system is required to
use.
- TrunkId
- The trunk identifier for this trunk. This is the value that identifies
this trunk to the network in Channel Identification information element.
