+This experimental patch splits one E1 card into three virtual cards,
+
+TS 1,2,3,4,5 is card 0
+TS 6,7,8,9,10 is card 1
+TS 11,12,13,14 is card 2
+
+This allows you to run one L2 TEI handler on each of the virtual cards,
+which is required if you want to run multiple BTS on a single E1 link.
+
+Thanks to Andreas Eversberg for this patch.
