We have a T1 line between two sites. Our main office and warehouse. When the line is down and I ping to the router which is an Adtran on the other site, we normally get the answer "Request timed out," but now we get the answer "TTL expired in transit." What does it mean?
they been down for more than 2 hours and ISP says that line seems to be fine but they dont see any traffic on it. Ive rebooted both Adtran devices. Ping did state request timed out till ISP tech started doing some testing.
