blob: bb94d342fcc8f1b9a84bdec259d264504379f4df [file] [log] [blame]
Harald Welte72914972009-08-10 23:36:53 +0200[diff] [blame]1This experimental patch splits one E1 card into three virtual cards,
2
3TS 1,2,3,4,5 is card 0
4TS 6,7,8,9,10 is card 1
5TS 11,12,13,14 is card 2
6
7This allows you to run one L2 TEI handler on each of the virtual cards,
8which is required if you want to run multiple BTS on a single E1 link.

10Thanks to Andreas Eversberg for this patch.
