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 | 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 appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999. 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 | Specifies whether to add a hop count to messages, if one is not already present, and decrement any existing hop counts. Values:
|
Maximum congestion level | Change | The maximum congestion level recognized by the remote exchange. When an exchange is overloaded it can attach an Automatic Congestion Level parameter to Release Messages at the end of a call. This parameter tells the calling exchange to reduce the calls to the overloaded exchange, and contains a congestion level which indicates how congested the overloaded exchange is. However, not all exchanges support changing their behavior to handle the varying degrees of congestions. For example, an exchange may only have two modes - uncongested and congested. This switch sends Automatic Congestion Level parameters only for levels that the remote exchange will recognize. Values:
|
CLLI | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999. 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 | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999.
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:
|
Local CLLI code override value | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999 and 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 | Specifies whether the MetaSwitch NE should play the error tones or announcements if the call fails (for example if the called party does not exist). Values:
|
Request remote echo cancellation devices | Change | Specifies whether the MetaSwitch NE should request echo cancellation resources from the remote destination rather than supplying its own. Values:
|
Confusion messages | Change | If the MetaSwitch NE is unable to recognize an ISUP message, it may discard the message. If this happens, this field determines whether the NE sends a Confusion message (ISUP message of type CFN) back to the sending exchange. If the sending exchange receives a Confusion message, it may try to resend a simpler message. The GR-246 specification requires that this behavior is configurable, but you are recommended to leave this field as the default; unrecognized messages should be very rare. Values:
|
Direct IXC connection | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999.
Specifies whether the remote exchange is a directly connected Inter-Exchange Carrier (IXC). This setting affects which parameters are sent in IAMs to the remote exchange. Values:
|
Peer network type | Change | The type of the network at the remote destination. This field is used only for ISUP tandem calls. If a call is rejected by a remote exchange, the rejection message will include a location value. If the calling remote exchange is not on the same network as the MetaSwitch, the MetaSwitch will change the location value from "local network" to "remote network" before passing the rejection back to the calling exchange. Values:
|
Maximum simultaneous continuity tests | Change | This field does not appear if the parent ISUP Local Signaling Destination's ISUP variant is set to UK. 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. The default is zero, which means that there is no limit to the number of simultaneous tests. |
Exchange performs LNP lookup | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999.
Specifies whether the remote exchange normally performs Local Number Portability (LNP) lookups for calls before routing them to the NE. Values:
|
International exchange | Change | Specifies whether the link to this remote destination is an international link. Values:
|
USI parameter coding type | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999. Specifies the coding of the USI parameter for voice calls at the originating or interworking exchange. Values:
|
Charge number and outgoing line information | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999. 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:
|
Jurisdiction information parameter | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999. Specifies whether the Jurisdiction parameter is allowed in an outgoing IAM to this remote exchange. Values:
|
Redirecting number parameter | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999.
Specifies whether the Redirecting Number parameter will be sent to this remote exchange if the call has been redirected. The Redirecting Number parameter, which exists only if a call has been redirected (for example by call forwarding), contains the number of the party that initiated the last redirection of the call. The Redirecting Number is often used by voicemail systems to decide which mailbox to direct a call to. This field is often used in conjunction with the Redirection Information parameter and the Original Called Number parameter. Values:
|
Redirection information parameter | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999.
Specifies whether the Redirection Information parameter will be sent to the remote exchange if the call has been redirected. The Redirection Information parameter is included in the IAM message only if a call has been redirected (for example by call forwarding), and contains the reason for the current redirection, the reason for the first redirection, and the number of redirections. The Redirection Information parameter is sent to the called party, and is typically used by voicemail systems to decide which greeting to play to the caller. This field is often set in conjunction with the Original Called Number parameter. Values:
|
Original called number parameter | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999.
Specifies whether the switch should include the Original Called Number parameter if a call has been redirected. The Original Called Number parameter contains the number of the number that was originally called, and is sent in Initial Address Messages (IAMs) to the called exchange. This parameter is often used in conjunction with the Redirecting Number parameter and the Redirection Information parameter. Values:
|
Access transport parameter | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999.
Specifies whether the Access Transport parameter will be included in messages to the remote exchange. The Access Transport parameter is generated only by originating and terminating exchanges (the exchanges on the access side), and contains information that is relevant only to the users or their connection to the network. Access Transport parameters are passed through the switch without alteration. Values:
|
Generic address parameter | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999.
Specifies whether the Generic Address parameter is allowed in an outgoing IAM to this remote exchange. Values:
|
Generic name parameter | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999.
Specifies whether the Generic Name parameter (containing the calling name) is allowed in an outgoing IAM to this remote exchange. Values:
|
Party information parameter | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999.
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:
|
Redirect capability parameter | Change | This field appears only if the parent ISUP Local Signaling Destination's ISUP variant is set to ANSI 1999. Specifies whether the softswitch should send the Redirect Capability parameter to the remote exchange when sending an Initial Address Message (IAM). The Redirect capability parameter is sent to the called party to indicate whether the remote exchange is allowed to redirect the call by releasing the circuit, and when it can do so (depending on the call state). If the parameter is not sent, the remote exchange is free to choose whether to redirect the call. Values:
|
CIP parameter | Change | Specifies whether the Carrier Identification Parameter (CIP) should be included on Initial Address Messages (IAMs) to the remote exchange. The CIP contains the 4 digit code identifying the carrier chosen for the call by the calling party.
If the call originated from this switch, a carrier is associated with the call if the FGD carrier requirement attribute is set during Number Validation to indicate that a carrier is required for the call. If the call originated from another switch, the CIP and TNS parameters will be provided by the originating switch.
In addition, the CIP parameter can be sent based on the carrier for the call, rather than for all calls to the remote exchange. This configuration option is not currently customer-accessible, so please contact your Support Engineer if you need this feature.
The CIP is related to the Carrier Selection Information (CSI) parameter, which indicates how the carrier was chosen (pre-subscribed or casual dialed). By default the CSI parameter is not sent. If you require the CSI parameter to be sent in IAMs, please contact your Support Engineer because this configuration option is currently not customer-accessible. Values:
|
Incoming ACC processing | Change | Specifies whether the softswitch should pay any attention to incoming messages containing the Automatic Congestion Level (ACC) parameter. ACC is a process that allows an overloaded exchange to attach an Automatic Congestion Level parameter to Release Messages at the end of a call, which tells the calling exchange to reduce the calls to the overloaded exchange. The current congestion level of the remote exchange is shown by the Congestion status field on this object. Values:
|
TNS parameter | Change | Specifies whether the softswitch should accept incoming IAMs if they contain the Transit Network Selection (TNS) parameter. This is used to indicate which carrier should be used to carry the call, and is typically removed just before the call is passed to the carrier's network. Note that this is not the same as the CIP parameter, which indicates which carrier the caller choose; the two carriers may not be the same. Note also that, unlike most of the other fields on this object, this field applies to incoming IAMs and not to outgoing IAMs. Values:
|
Congestion status | Read only | The current level of congestion in the ISUP stack of the remote exchange. Values:
|
Availability status | Read only | The status of the ISUP stack in the remote exchange. Values:
|
ACC congestion status | Read only | ACC congestion status. Values:
|
Deactivation mode | Change | Specifies how child objects should be deactivated when deactivating this object. Values:
|

|
Diagnostics - API trace - enabled | Change | Specifies whether API tracing is enabled for this object. Values:
|
Diagnostics - API trace - trace tag | Change | An optional text string inserted into API tracing and PD logging for this object. (This string can include accented / international characters as defined in ISO 8859-1.) If you want to filter on this tag in the craft interface, do not include spaces or any of the characters ^ \ $ * + ? | ( ) , . ' ' " [ ] { }. |
