hi all, i am doing some testing with fr, i have 2 2610 connecting to 2 hssi port on a ascend stdx8000 fr box by way of v.35 cables, from the ascend i connect to a Larscom T45 csu/dsu device i am running DS3 here, the larsom is connected to the ascend box by a 50 pin x-over cable , from the larscom i go to a csico 7200(DS3 connection), i can ping between 2 cisco 2610 but cannot reach the 7200, i even enable larscom on the cisco (dsu 2), the map will become active for about 20 sec on the ascend and it will drop, have anybody done this on thier network, i am thinking the ascend does not work w/ the larscom, cisco's are DTE and ascend is DCE on this test thanks, Fil __________________________________________________ Do You Yahoo!?
