Hi all,

I'm implementing an SMSC and have run into a (possible) documentation problem.

In the MO-Forward-Message-Ack, where user error included, the programmer's manual indicates two parameters:

- SM delivery failure cause, defined as an enumerated plus up to 200 diagnostic info bytes.

- Diagnostic Info, used only if the previous is present and composed of up to 200 diagnostic info bytes.

Checking the ASN.1 for GSM 29.002, apparently those parameters are the same (there is a diagnostic info embedded into SM delivery failure cause and nothing else).

Is this an error on the manual? Should I use both parameters or just the SM delivery failure cause?

Thanks in advance and best regards.
