Help decoding an FTAM capture from a synchronous line, using LAPB encapsulation

FTAM
X.25
LAPb
retag add tags

I have several captures (.cap files) performed with our own physical device. In the past (versions of 2007!) Wireshark could decode LAPB/X.25/FTAM on this file. I'm using the same capture file from then, but can not figure out how to force Wireshark to do the decode.

Any ideas? I could send copies of the .cap file and also printouts from Wireshark with the decode.

Thanks in advance for any help.

Can you place a capture file on a public file share and update the question with a link to it.

Please find a sample capture file for this case at https://drive.google.com/file/d/1_oJ3...

A printout from a very old Wireshark shows how it decoded some of the frames, here: https://drive.google.com/file/d/11lTy...

This is what I am looking for... being able to decode as it did in the past.

Thanks for any help!
