ISUP Remote Signaling Destination

The ISUP Remote Signaling Destination objects are children of the ISUP Local Signaling Destination object.

There is an ISUP Remote Signaling Destination object for each adjacent exchange. This object contains configuration parameters and status information for the ISUP signaling stack within the adjacent exchange.

Note that you must configure a Signaling Destination object for the adjacent exchange before you can configure the ISUP Remote Signaling Destination object.

For initial configuration of an ISUP Remote Signaling Destination, you need to do the following:


Parameter

Access

Description
ISUP Remote Signaling Destination index Read only The EMS's identifier for this ISUP Remote Signaling Destination object. This is used to identify the object when using the EMS's configuration export / import function.
Destination Change Inactive The Signaling Destination corresponding to the remote exchange, or to the cluster containing the remote exchange. Select from the displayed list of configured Signaling Destinations. If there is no Signaling Destination with a matching point code, or if you attempt to set a default MTP3 destination (point code 0-0-0), this field will display Reference not valid.
Network number Change Inactive A numeric identifier for the remote network, which will appear in transit billing records for outgoing calls to this remote exchange. Specify a different number for each remote network, so that all remote exchanges on the same network have the same network number.
Active hop counting Change Inactive Specifies whether to add a hop count to messages. Values:
  • False (default)
  • True
Maximum congestion level Change Inactive Maximum congestion level recognized by the remote exchange. Values:
  • Level 1
  • Level 2
  • Level 3 (default)
  • Uncongested
Error handling mode Change Inactive Specifies the error handling mode used by the remote exchange. Values:
  • No tones required (default)
  • Tones always required
  • Tones if interworking
Request remote echo cancellation devices Change inactive Specifies whether the MetaSwitch NE should request echo cancellation resources from the remote destination rather than supplying its own. Values:
  • True (default)
    Request echo cancellation resources from the remote destination.
  • False
    The NE will supply its own echo cancellation resources. This value is typically used when the NE is acting as a tandem switch and the remote destination is an end office, if echo cancellation resources at the end office are scarce or of lower quality.
Confusion messages Change Inactive Specifies whether the local exchange generates a confusion message when an unrecognized message is received from the remote exchange. Values:
  • True (default)
  • False
Peer network type Change Inactive Specifies the type of the network to which the remote exchange belongs. Values:
  • Same network (default)
  • Local network
  • Private network
  • Transit network
  • International network
You are recommended to leave this parameter with its default setting.
Maximum simultaneous continuity tests Change This field only applies in North America. You should leave this field with the default value, zero.
Incoming ACC processing Change Inactive Specifies whether incoming ACC processing is enabled. Values:
  • True (default)
  • False
TNS parameter Change Inactive Specifies whether the Transit Network Selection parameter may be received on an incoming call from this remote destination. Values:
  • True
  • False (default)
Congestion status Read only The current level of congestion in the ISUP stack of the remote exchange. Values:
  • Uncongested
  • Level 1
  • Level 2
  • Level 3
Availability status Read only The status of the ISUP stack in the remote exchange. Values:
  • Available
  • Unavailable
  • Unavailable - busy
  • Unavailable - failed
ACC congestion status Read only ACC congestion status. Values:
  • Level 1
  • Level 2
  • Level 3
  • Uncongested
Deactivation mode Change Specifies how child objects should be deactivated when deactivating this object. Values:
  • Normal (default)
    Shut down child objects normally before deactivating the object.
  • Quiesce
    Deactivating the ISUP Remote Signaling Destination object in quiesce mode will wait for all existing child objects using the object to be completed before deactivation. No new child objects using this object will be accepted during this deactivation period.
  • Abort
    Deactivate the object and all its child objects immediately. (This may result in errors at remote systems.)
Alarm state Read only Specifies whether any alarms are currently raised for this object. Values:
  • Clear
    No alarms are currently raised.
  • Attention Required
    Attention Required - the object is not operating normally, and needs operator intervention.
Alarm log correlator - Attention Required Read only Identifier of the log message for the event that caused the last Attention Required alarm state for this object. This field is reset when the Attention Required alarm events field is reset to zero.
Attention Required alarm events Read only / Reset Number of times (since this field was reset) that this object's alarm state has gone to Attention Required.
Alarm log correlator - Attend To Dependent Read only Identifier of the log message for the event that caused the last Attend To Dependent alarm state for this object. This field is reset when the Attend To Dependent alarm events field is reset to zero.
Attend To Dependent alarm events Read only / Reset Number of times (since this field was reset) that this object's alarm state has gone to Attend To Dependent.
Alarm state changed timestamp Read only Time at which the Alarm state last changed.
Alarm events reset timestamp Read only Time at which the Attention Required alarm events field was last reset to zero.
Media Channel and Circuit Group Attention Required alarms Read only The total number of Media Channels and Circuit Groups (and their child objects) associated with this ISUP Remote Signaling Destination that are in Attention Required state.
Media Channel and Circuit Group Attention Required alarm events Read only / Reset The total number of times that the alarm state for a Media Channel or Circuit Group child object has gone to Attention Required.
Media Channel and Circuit Group Attend To Dependent alarms Read only The total number of Media Channels and Circuit Groups (and their child objects) associated with this ISUP Remote Signaling Destination that are in Attend To Dependent state.
Media Channel and Circuit Group Attend To Dependent alarm events Read only / Reset The total number of times that the alarm state for a Media Channel or Circuit Group child object has gone to Attend To Dependent.
Summary child alarm state Read only Summarizes the alarm status for all children of this object. Values:
  • Clear
    No alarms are currently raised.
  • Attention Required
    Attention Required - one or more child objects are not operating normally, and need operator intervention.
  • Attend To Dependent
    Attention Required elsewhere - another object on which one or more child objects depend is not operating normally.
Diagnostics - log level Change Specifies the level of logs recorded for this object. Logs with a priority equal to or greater than the priority specified are recorded. Set to Default level to use the system-wide default level. Values:
  • Level 10 (diagnostics)
  • Level 20 (verbose statistics)
  • Level 30 (verbose operational)
  • Level 40 (statistics)
  • Level 50 (audit)
  • Level 60 (operational)
  • Level 70 (unexpected)
