This does not appear to be an SS7 issue. Check your cables and connections, particularly for loose contacts or potential shorts (e.g. where the jumper cable on the Krone block is making poor contact or the cable hasn't been stripped cleanly and is touching another pair or the frame itself, or where stranded cable has been punched into a Krone block instead of solid core cable). Sangoma cards can give signal strength readings. For info on how to get this, check: http://wiki.sangoma.com/Wanpipemon-T1-E1-physical-Line-alarms It can also be load/interrupt related it you have multiple cards, but unlikely with just one A101, unless an old motherboard and the card is sharing IRQs unhappily with too many other devices.
