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:


You cannot delete an ISUP Remote Signaling Destination or change its Destination field if it has one or more Proxied ISUP Circuit Group child objects. You will need to delete these child objects before you can delete or change the parent object.


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. This list does not include internal destinations on the Signaling Gateway referenced by the parent ISUP Local Signaling Destination. 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.
Cluster member address Change Inactive This field is visible only if the Destination field specifies a destination whose type is Cluster. It specifies the final byte of the destination's point code, identifying an individual member within the cluster.
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
CLLI Change Inactive CLLITM: Common Language(C) Location ID. This is a string of 11 alphanumeric digits assigned by TelcordiaTM, specifying the exact location of the remote exchange. If necessary, you can override this value on a particular ISUP Media Channel to the remote exchange. The CLLI is used to provide diagnostics information in circuit validation tests. If you do not know the CLLI of the remote exchange, you can set this field to any alphanumeric string.
Override local CLLI code Change Inactive Specifies whether to override the default local CLLI (specified on the ISUP Local Signaling Destination) with a different value to be presented on messages to this remote destination. If necessary, you can also override this value on a particular ISUP Media Channel to the remote exchange (rather than on the exchange as a whole). Values:
  • True
  • False (default)
Local CLLI code override value Change Inactive This field appears only if Override local CLLI code is set to True. The CLLI to be presented to this remote destination. Specify a string of 11 alphanumeric digits as assigned by Telcordia.
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
Direct IXC connection Change Inactive Specifies whether the remote exchange is a directly connected IXC. Values:
  • True
  • False (default)
You are recommended to leave this parameter with its default setting.
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 Specifies the maximum number of circuits across all circuit groups to the remote signaling destinatination that a continuity test will be run on at any given time. Specify a value. The default is zero, which means that there is no limit to the number of simultaneous tests.
Exchange performs LNP lookup Change Inactive Specifies whether the remote exchange normally performs Local Number Portability (LNP) lookups for calls before routing them to the NE. Values:
  • True (default)
    The remote exchange is in the same local porting area as the NE, and can perform its own LNP lookups.
  • False
    The remote exchange is outside the NE's local porting area (so has no LNP information for it), or is in the local area but does not have LNP lookup capability.
If the NE's Config Set type is LNP lookup, the NE can perform its own LNP lookup if the remote exchange has not already done this, so will continue to route the call even if the remote exchange has not done so as expected. However, setting this field to True allows the NE to log this event for diagnostic purposes.
USI parameter coding type Change Inactive Specifies the coding of the USI parameter for voice calls at the originating or interworking exchange. Values:
  • Speech (default)
  • 3.1kHz Audio
Charge number and outgoing line information Change Inactive Specifies whether the Charge Number and the Outgoing Line Information parameters are allowed as a pair in an outgoing IAM to this remote exchange. Values:
  • True
  • False (default)
Jurisdiction information parameter Change Inactive Specifies whether the Jurisdiction parameter is allowed in an outgoing IAM to this remote exchange. Values:
  • True
  • False (default)
Redirecting number parameter Change Inactive Specifies whether the Redirecting Number parameter is allowed in an outgoing IAM to this remote exchange. Values:
  • True
  • False (default)
This parameter must be set according to the capabilities of the remote exchange. However, if it is left as False, some Call Services interactions (in particular Message Center) may not work correctly.
Redirection information parameter Change Inactive Specifies whether the Redirection Info Parameter is allowed in an outgoing IAM to this remote exchange. Values:
  • True
  • False (default)
Original called number parameter Change Inactive Specifies whether the Original Called Number parameter is allowed in an outgoing IAM to this remote exchange. Values:
  • True
  • False (default)
This parameter must be set according to the capabilities of the remote exchange. However, if it is left as False, some Call Services interactions (in particular Message Center) may not work correctly.
Access transport parameter Change Inactive Specifies whether the Access Transport parameter is allowed in any outgoing message to this remote exchange. Values:
  • True
  • False (default)
Generic address parameter Change Inactive Specifies whether the Generic Address parameter is allowed in an outgoing IAM to this remote exchange. Values:
  • True (default)
  • False
Generic name parameter Change Inactive Specifies whether the Generic Name parameter (containing the calling name) is allowed in an outgoing IAM to this remote exchange. Values:
  • True (default)
  • False
Party information parameter Change Inactive Specifies whether the Party Information parameter (containing the calling name) is allowed in an outgoing IAM to this remote exchange. This parameter is typically used only in Canada. Values:
  • True
  • False (default)
