Answer
Hi, Alex

I think it may be possible, but this is no easy feat to do.

first, data in a cable modem is via ATM transmission standard, see ITU recommendations J.222.0 to J.222.3 for a clear definition on the standard used.

For the equipment you would probably need an Add/Drop multiplexer, or an E1 decoder, not unless you can dump and read an STM frame format.

in general YES" it is possible to do a data stream or data packet dump, but it is far more complicated than what you probably imagined.

regards.
