ISP Information:
A method of constructing transistors which produces microchips that run with relatively low power consumption compared to other methods. Most of the chips found in a modern PC are built using CMOS technology. ISP Glossary:
CMOS - (partially munged in processing) when a specific single strand has to be located. They're all identical, and not identified. [TELECOM Digest Editor's Note: You are reading the report of a television talking head to his/its viewers. The not-too-intelligent talking head is explaining to his even-less-intelligent viewers what has happened. They don't know anything about rings or specific strands of fiber. All the viewers know is their 911 service has gone out and he is trying to explain why, albiet with a sort of dramatic flair for details. PAT]Just as a point of clarification -- not all fiber is installed inrings. And we are not necessarily talking about SONET when you speakof feeding a PSAP. It is more than 99.9% of the time a single tailcircuit.The fair city in which I toil was, until recently, served by a singlefeed into the PSAP. The serving CO was on multiple rings, but thefeed to the PSAP was a single cable. Over the summer the city spentseveral weeks and a many thousands of dollars to lay in a diverse pathfrom an alternate wire center (CO).The city had known about the problem for at least 5 years, andpossibly more, but as we had a backup facility that was also manned 24hours a day, it wasn't a real priority. It wasn't until they built anew facility at one of the locations and consolidated that the problembecame critical. We still have a backup facility, but that facilityis no longer manned around the clock. They have to shift the calltakers from the primary to the backup and that takes about 30 minutes-- once transportation arrives. As there was little chance of theprimary facility going down, because of backup power and redundantequipment, it suddenly pointed out the biggest single point-of-failurewas the lack of a diverse feed.Now, if they can just get enough people to man the call stations ...Rodgers Platt
