SCCP Options
The SCCP Options are those configuration values that govern the overall SCCP functionality . There is a single instance of this resource, which contains each of the individual options that can be retrieved and set.
The SCCP Options resources can only be updated. The SCCP Options cannot be created or deleted.
Select the page. The page displays the elements on the SCCP Options View and
Edit pages.
Table 5-23 SCCP Options Elements
| Element | Description | Data Input Field |
|---|---|---|
| Allow Msg During Rsmbly Err | It specifies whether message will be allowed or discarded during reassembly failure. If alwMsgDuringRsmblyErr is True then message will be forwarded to upper layer for further processing. If alwMsgDuringRsmblyErr is false then message will be discarded and an XUDTS will be generated (provided return on error is set in the XUDT message). | Default - False |
| Class 1 Message Sequencing | Enables or disables Class 1 message sequencing. When set to Enabled, Class 1 messages are guaranteed to be sequenced, but the messages are not load shared. When set to Disabled, Class 1 message sequencing is not guaranteed, but the messages might be load shared (if appropriate configuration exists). | |
| Default fallback | Default fallback option. This parameter specifies the action that is taken if the last translation doesn't match when performing GTT using a FLOBR-specific GTT mode. When set to false, GTT fails and the MSU is discarded. When set to true, GTT is performed based on the last matched entry. | Default - False |
| Default GTT mode | Default GTT mode. The system default value of the GTT mode hierarchy used by the DSR when performing GTT.i | Default - Cd |
| XUDT Segmentation feature | It specifies whether the XUDT Segmentation feature is enabled. If isSegXUDTfeatureEnable is true then the feature is enabled. | Default - False |
| MTP Routed GTT | System-wide option for MTP Routed GTT, used to define GTT behavior on MTP Routed MSUs. | Default - Off |
| MTP Routed GTT fallback | System-wide option for MTP Routed GTT fallback, used to define error handling in case of failure for MTP routed MSUs. | Default - Mtproute |
| Reassembly timer duration for ANSI | Reassembly timer duration for ANSI domain. Time period after recieving the first segment, while waiting to recieve all the remaining segments related to same ANSI XUDT segmented message. | Default - 5000 , [Minimum,Maximum] - [5000,20000] |
| Reassembly timer duration for ITU | Reassembly timer duration for ITU domain. Time period after recieving the first segment, while waiting to recieve all the remaining segments related to same ITU XUDT segmented message. | Default - 10000 , [Minimum,Maximum] - [10000,20000] |
| Length of Segmented MSU | Length of Segmented MSU. | Default - 200 , [Minimum,Maximum] - [200,272] |
| Transaction-based GTT loadsharing is enabled for UDTS and Class0 UDT messages | When set to Udt, transaction-based GTT loadsharing is enabled for UDTS and Class0 UDT messages. When set to Xudt, transaction-based GTT loadsharing is enabled for XUDTS and Class0 XUDT messages. When set to Both, transaction-based GTT loadsharing is enabled for UDTS, XUDTS, Class0 UDT and Class0 XUDT messages. When set to None, transaction-based GTT loadsharing is disabled for UDTS, XUDTS, Class0 UDT and Class0 XUDT messages. To update this parameter, the Transaction Based GTT Loadsharing feature must be enabled (using the GTT Feature Control (/vstp/featureadminstates)). | |
| Transaction-based GTT loadsharing is enabled for UDTS and Class1 UDT messages | When set to Udt, transaction-based GTT loadsharing is enabled for UDTS and Class1 UDT messages. When set to Xudt, transaction-based GTT loadsharing is enabled for XUDTS and Class1 XUDT messages. When set to Both, transaction-based GTT loadsharing is enabled for UDTS, XUDTS, Class1 UDT and XUDT messages. When set to None, transaction-based GTT loadsharing is disabled for UDTS, XUDTS, Class1 UDT and Class1 XUDT messages. To update this parameter, the Transaction Based GTT Loadsharing feature must be enabled (using the GTT Feature Control (/vstp/featureadminstates)). | |
| Transaction parameter for incoming UDT(S) messages | Defines the transaction parameter for incoming UDT(S) messages. Messages with this parameter are routed to the same load-shared remote Point Code within a MAPGROUP or MRNGROUP. When set to Mtp, transaction-based GTT loadsharing is performed using the MTP algorithm. When set to Tcap, transaction-based GTT loadsharing is performed using the TCAP algorithm. When set to Sccp, transaction-based GTT loadsharing is performed using the SCCP algorithm. When set to Enhmtp, transaction-based GTT loadsharing is performed using the ENHMTP algorithm. To update this parameter, the Transaction Based GTT Loadsharing feature must be enabled (using the GTT Feature Control (/vstp/featureadminstates)). | |
| Transaction parameter for incoming XUDT(S) messages | Defines the transaction parameter for incoming XUDT(S) messages. Messages with this parameter are routed to the same load-shared remote Point Code within a MAPGROUP or MRNGROUP. When set to Mtp, transaction-based GTT loadsharing is performed using the MTP algorithm. When set to Sccp, transaction-based GTT loadsharing is performed using the SCCP algorithm. When set to Enhmtp, transaction-based GTT loadsharing is performed using the ENHMTP algorithm. To update this parameter, the Transaction Based GTT Loadsharing feature must be enabled (using the GTT Feature Control (/vstp/featureadminstates)). | |
| Velocity of Travelling | Defines the velocity of travelling. | Default - NA , [Minimum,Maximum] - [1,700] |
| SMS Delivery | SMS Proxy Delivery Functionality Status | . [Range = On, Off; Default = Off;] |
| SMS Origination | SMS Proxy Origin Functionality Status. | [Range = On, Off; Default = Off;] |
| SMS Termination | SMS Proxy Terminate Functionality Status. | Range = On, Off; Default = Off |
| Allowed First Segment Length | Specifies the allowed length of the first XUDT segment. | Allowed Value: Maximum:272 Minimum:0
Default: 0 |
| TCAP Error Discard | TCAP Error Discard.
If it is turned Off, MSU will be processed. While if it is turned on, MSU will be discarded. |
Range = On, Off
Default = Off |
