let's see ( putting on my thinking cap )
the DLCI field of the frame relay header is 10 bits, meaning a maximum of
1023 DLCI numbers.
did not find anything on the frame relay forum site www.frforum.com, but
according to Darren Spohn's Data Network Design ( out of print but a third
edition is being written ):
DLCI 0 = in channel signaling ( lmi-type ansi )
DLCI 1-15 are reserved
DLCI 1008-1022 are reserved ( I always thought it was 1005-1022. wonder
where I got that from )
DLCI 1023 = in channel layer management ( lmi-type cisco )
that leaves 16-1007 as possible DLCI's for production - or 992 total.
interesting.

As I recall the theoretical limit on the number of DLCIs is 999. This from a
Mark Miller book. The book is at work so I can't check it right now. Not
sure of vendor specific limits either.
