Please log in for more thread options Long story..short version. Just before I started with my current employer, they moved office locations. They hired a local contractor to install the electrical and low voltage cabling (voice and data). When I saw the patch panel terminations, I got nervous. Each cable in the patch panel has the jacket of the cable peeled back the full legnth of the panel and the indivdual pairs are bound tightly together. pictures http://geocities.yahoo.com/bhokey/misc/DSC03790.JPG http://geocities.yahoo.com/bhokey/misc/DSC03791.JPG http://geocities.yahoo.com/bhokey/misc/DSC03792.JPG Are network seems notorious slow to me. We have 2 bonded T1's to the internet and all 70 users here access a web based app to do almost all their work. Ping times are alway below 100ms and when I check our internet utilization we occassional max out but not for longer than 10 seconds at a time maybe once or twice a day. The Cisco switchess dont see any CRC's and all the machine NICS and ports on the switch are forced to 100/full. Could the patch panel termination be casuing this slow down. | |||||||||||||||||||||||||||||||||||||

Actually...God isnt the only one who knows....I know....and found out the hard way. We have a standardized cublice structure of about 5-7 workstations in a cubicle area. He set up 2-3 cubicles (15-21 machines) on a single circuit. Its a joke. The problem is that it has been almost a year since we moved to this building....(I identifed the potential cabling issues 2nd day I was there) and management has yet to act on it. I am almost sure it is too late. BTW. I have access to a Fluke DSP 4000 to certify cable and an Optiview II and every one I tested passed fine. | |||||||||||||||||||||||||||||||||||||

Actually, stripping back the sheath is common in telecom work. If the wiring is fairly dense, the sheath takes up a lot of space. On some of the systems I've worked on there were 224 pairs terminated on a panel. You simply don't have room for sheaths in that sort of install. | |||||||||||||||||||||||||||||||||||||
