I took a look at the debian sources in
https://salsa.debian.org/pkg-voip-team/dahdi-linux/

Apparently the 'dahdi-linux' package contains a copy of
the oslec module, which it puts in a local drivers/staging/echo
directory.

It has done so since at least 2015 when the package moved
from subversion to git.
