2.23 vSTP XUDT UDT Conversion Feature

In the network world, certain nodes package messages in XUDT format to facilitate segmentation of long SCCP messages into multiple parts, even if the data is not segmented and there are no further messages in the sequence. When these XUDT messages passes from another networks the receiving network may not be able to support the XUDT format. Therefore the XUDT(S) messages are required to be converted to UDT(S) messages.

vSTP supports the conversion of XUDT (S) messages to UDT (S) format and vice versa for both MTP3 and SCCP routed SCCP messages.

The feature allows the conversion of the following messages:

• A UDT(S) message to an XUDT(S) message
• An XUDT(S) message to a UDT(S) message

The XUDT(S) to UDT(S) conversion and vice versa is applicable to segmented and non-segmented UDT(S) and XUDT(S) messages. It is supported for messages destined for both ITU and ANSI domains. The feature is applied to both MTP3 routed SCCP messages and SCCP routed SCCP messages. q XUDT<->UDT Conversion feature shall be applied to SCMG Messages too.
