If you lose 1 way, you have ever the second. If you have less of 8 BTS, you can stay with 1+0. 21st October 2007 at 21:35 #49418 Abdullah kHANGuest What is odu and idu? 23rd October 2007 at 18:41 #49419 patrick.frGuest OutDoor Unit InDoor Unit Author Posts Viewing 4 posts - 1 through 4 (of 4 total) The forum ‘Telecom Design’ is closed to new topics and replies.
