xpp: pri: fix RS1 init in E1 CAS mode
Force some reserved bits to really be 1 in E1 mode (otherwise terrorists will win). (Closes issue DAHLIN-264) Signed-off-by: Oron Peled <oron.peled@xorcom.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/branches/2.5@10353 a0bf4364-ded3-4de4-8d8a-66a801d63aff
