Sounds like a weekly EAS test. The FCC requires cablcos, just like broadcasters, to transmit a weekly test on all cable channels except local stations that request that their channels not be interrupted. It should only last about 1 minute tops and if the system malfunctions, it should automatically shutdown after 3 minutes. If it doesn't, then they have a problem. Call your cableco to tell them.
