You can just comment out/remove that condition from the source code. It should
allow chan_ss7 to continue without any bad side effects.

Faulting the link is required by the ss7 specifications when the other end is
not sending SLTA. But apparently there are some systems that do not obey this,
or maybe the other end turned it off.

The reason for the fail-on-SLTA is something to do with detecting link
failures early enough to enable quick switchover to another line to keep a
99.999% uptime, or something like that. You probably don't even have another
redundant link, so you can safely ignore that part of the spec.
