hey guys have a quick question. today i had an issue connecting a t1 to a cisco as5400 i was getting a timer expire error. doing some research my gear T310 timer was set to 10000ms and the as5400 side was set to 30000ms. doing some searching around i can't seem to find what the true industry standard is for the T310 timer. i'm getting mixed results with 10000ms and 30000ms. of course the Q.931 document is not freely available so it's hard to find out what the true recomended timer setting is. anyone have any thoughts. what are the pbx's you guys have installed set to.
