是要配合機房沒錯,要換小烏龜,是什麼型號要換什麼型號
1.用一段時間的,叫它換線不是更好

2.要換,應該要有原因吧,自己也可以先檢查看看小烏龜內數據,是什麼照成
Signal to Noise (SNR):
　5db or below =bad, no sync/intermittent sync
　8db-13db = average - and no sync issues
　14db-22db = very good
　23db-28db = excellent
　29db-35db = rare, can throw a rock at co/remote

Line attenuation
　teens = rare, great copper lines, close to C.O./Remote
　20-30 = excellent
　30-40 = very good
　40-60 = average
　60-65 = poor
　65 and above will have issues

合勤科技-600...如何查看他的數據呢?
