The ISDN dissector doesn't know anything about either of those.  Neither 
of those are ISDN (B-ISDN maybe, but not classic ISDN), so it's not 
clear that they *should* know about them.

Should the eyesdn Wiretap module return a link-layer type of 
WTAP_ENCAP_PER_PACKET for eyesdn files, and supply link-layer types of 
WTAP_ENCAP_ISDN for channels 0 through 30, WTAP_ENCAP_ATM with a 
pseudo-header indicating that the frame is an ATM cell for channel 128, 
and something appropriate (which might have to be added) for channel 129?
