FileSequenceNumber

Validations ASN.1 Parent Types

A unique reference which identifies each TAP Data Interchange sent by one PMN to another, specific, PMN.

The sequence commences at 1 and is incremented by one for each subsequent TAP Data Interchange sent by the Sender PMN to a particular Recipient PMN.

Separate sequence numbering must be used for Test Data and Chargeable Data.  Having reached the maximum value (99999) the number must recycle to 1.

Note that in the case of retransmission for any reason this number is not incremented.

Note that where the file sequence number is being reused with a file already received and successfully processed and the content of the two files is different, then the received file is to be considered as ‘invalid reused sequence number’ and rejected using the RAP process.  Where the content of the two files is the same then the file is to be considered as a ‘copy’ of the original file and should be ignored (i.e. not rejected).
