I have a max 4000 with 4 E1. In Main Edit Menu there are: 00-000 System 10-000 Net/E1 20-000 Net/E1 .. in 10-000 I can activate two lines, but in 20-000 i read \"Message #131 - Interface not available on unit\". So my costumer can use only 2 E1 instead of 4 E1. Software version is 6.1.3. ++ Ascend Users Mailing List ++ To unsubscribe: send unsubscribe to ascend-users-request at bungi.com Archives: http://www.nexial.com/mailinglists/
