Service Logic Host Route

The Service Logic Host Route object is a child of the Service Logic Host Routes object.

A Service Logic Host Route (SLHR) is used to determine the local and remote access points to be used for a specific type of TCAP query, and represents how outgoing messages should be addressed by including pointers to the subsystem number (SSN) and Application Context of outgoing messages.


Parameter

Access

Description
Service Logic Host Route index Create A numeric value that identifies this SLHR among all other SLHRs on the NE. This field is optional; if you do not supply a value, the EMS assigns one.
Service Logic Host Route name Change Unique user-friendly name identifying the Service Logic Host Route. Specify a name of up to 64 characters. If a name is not specified, the EMS displays a default.
SSN ID Change Inactive The SCCP subsystem number associated with the host route. Range: 34 - 254. This SLHR can access any SCCP that has a Local SCCP Access Point object with this SSN value.
Translation type Change inactive The SCCP translation type associated with this host route. This determines how requests associated with this host route are routed for Global Title Translation. Each SCCP that this SLHR can access should have an SCCP GT Translator child object with this translation type. Some applications have standard translation type values, although these may need to be overridden in specific networks. These standard translation type values are specified in ANSI T1.112.3, Annex A. Range: 0 - 255
Include protocol version in outgoing transactions Change inactive Specifies whether the protocol version field should be included in the dialogue portion of outgoing TCAP transactions initiated by this exchange. Values:
  • True
  • False (default)
Ignore protocol version in incoming transactions Change inactive Specifies whether the protocol version field in received TCAP packets should be ignored. If this field is set to False, any protocol version information in the dialogue portion of a received transaction initiating TCAP message must match at least one of the protocol versions specified in the Supported TCAP Protocol Versions field. Values:
  • True
  • False (default)
Supported TCAP protocol versions Change inactive The TCAP protocol versions supported on this SLHR. The use of this is twofold.
  • If the Include protocol version in outgoing transations field is set to True, it is the value included in outgoing transaction initiating requests for this host route.
  • If the Ignore protocol version in incoming transactions field is set to False, it is used for checking the protocol version in received TCAP messages.
At least one of the possible versions must be specified when Include protocol version in outgoing transations is True or Ignore protocol version in incoming transactions is False. Values:
  • ANSI 1996
  • ANSI 2000
Application Context Change inactive The application context associated with this Service Logic Host Route entry. Select from the drop-down list. If no application context is specified, the Include application context in outgoing transactions field must be set to False.
Include application context in outgoing transactions Change inactive Specifies whether the configured application context information should be included in the dialogue portion of outgoing TCAP transactions initiated by this exchange. It can be set to True only if a valid application context is configured. Values:
  • True
  • False (default)
Ignore application context in incoming transactions Change inactive Specifies whether the application context field in received TCAP packets should be ignored. If this field is set to False, any application context information in the dialogue portion of a received transaction initiating TCAP message must match the configured application context information. Values:
  • True
  • False (default)
Incoming query routes Change inactive Specifies whether this SLHR can be used for incoming TCAP queries. Values:
  • All routes permitted (default)
    Allow incoming TCAP queries from any remote access point.
  • Specified routes only
    Allow incoming TCAP queries only if the remote and local access points match an incoming Query Route object that is a child of this SLHR. If you intend to use this SLHR for CNAM query handling (as specified in the Global Caller ID Services object), you must use this value.
  • No routes permitted
    Do not allow any incoming TCAP queries from remote access points to use this SLHR.
Origin of last unauthorized Query message Read only This field does not appear if Incoming query routes is set to All routes permitted. The point code from which the last unauthorized incoming TCAP query was received. (This query will have been rejected because it did not match a Query Route for this SLHR, or because the SLHR does not accept any incoming queries.)
Outgoing query routes Change inactive Specifies whether this SLHR can be used for outgoing TCAP queries. Values:
  • All routes permitted (default)
    Allow outgoing TCAP queries originating from any local access point.
  • Specified routes only
    Allow outgoing TCAP queries only if the local access point matches an outgoing Query Route object that is a child of this SLHR.
  • No routes permitted
    Do not allow any outgoing TCAP queries to use this SLHR.
In use by Read only Indicates which applications are using this Service Logic Host Route. A Service Logic Host Route entry can be disabled only when no applications are using it. This field is set to zero or more of the following values:
  • AIN
  • AIN-based LNP lookup
  • AIN-based Toll Free lookup
  • Automatic Callback / Automatic Recall
  • Calling Name Delivery
  • Message Waiting Indicator
  • Completion of calls to busy subscribers
  • Off-Hook Delay Routing application
  • Generic Specific Digit String service
  • Off-Hook Delay Subscriber application
  • Termination Attempt application
  • CNAM Query Handling service
Note that for an application to be considered as using a Service Logic Host Route, the application must have been activated and have an active reference to the SLHR.
References count Read only The total number of applications that refer to this record. If one or more applications refer to this record, it cannot be deleted.
Import - number of objects imported Read only The total number of objects (including child objects) read from the import file so far in the current or most recent import operation.
Import - status Read only The status of the current or most recent import operation, if any. Values:
  • None
  • In progress
  • Succeeded
  • Failed
Import - mode Change Whether the imported information is to replace existing EMS objects or to add new ones. This field provides additional checking on the import operation if required. Values:
  • Do not overwrite
    The imported information is to add new objects. If the file contains objects that already exist in the EMS, the import operation will fail and will not overwrite them.
  • Do not create
    The imported information is to update existing objects. If the file contains objects that do not already exist in the EMS, the import operation will fail and will not create them.
  • Overwrite or create
    No checking. The import operation will create or update objects as required.
Import - file Change The name of the text file (in the EMS User's home directory on the EMS Server) from which configuration information for this object will be imported. The maximum length of the filename is 32 characters.
Import - log correlator Read only If the import status is Failed, this field contains a correlator for the log message that contains details of the failure. Click on the 'go to log' button next to this field to jump to this message in the EMS log viewer window.
Import - correlator metaswitch Read only If the import status is Failed, this field contains the name of the EMS Server or MetaSwitch Network Element that generated the failure log. You may need this information to find the log in the EMS log viewer window.
Requested status Read only Specifies whether an administrator has attempted to activate the Service Logic Host Route. Values:
  • Active
    The object has been activated.
  • Inactive
    The object has not been activated or has been deactivated.
  • Disabled
    The object has been disabled.
Actual status Read only Specifies the current status of the Service Logic Host Route. Values:
  • Active
    The object is active.
  • Activating
    Activation is in progress.
  • Deactivating
    Deactivation is in progress.
  • Inactive
    The object is inactive.
  • Disabled
    The object has been disabled.
  • Activation Failed
    The object is inactive because an activation attempt has failed.
