Is your apartment a large Multiple Dwelling Unit (Dozen + units), townhome/duplex or split-level large house? I am trying to determine where the cable would enter the dwelling & if Cable TV
taps, amplifiers & Line Extenders might be on site. I still suspect Network Distibution, "bad tap port", Line Extender, Loose hard line fitting, "scored" center conductor, etc...
Most 750mhz Cable systems have a Forward Data Carrier=FDC (Downstream) & a Return Data Carrier=RDC (Upstream). Those are the specific frequencies that the Field/Service Tech should be reading with their Signal Level Meter (SLM
). In the Cox Phoenix system, I would read FDC 75.500 MHz & document the signal level. Next I would read the RDC 16.000 MHz & document the signal level. There are 4 main spots to check SLM
's. Input cable to Set-Top Box/Analog Cable in or Modem input, output of each Splitter port/Ground Block, input to Splitter/Ground Block & Tap port(s) in Ped or Pole.
If any of those frequencies were out of range, then I would troubleshoot from each Cable Outlet & the HSI Data Jack. I would replace all Jumper Cables, Cat5 Cables, Wallplates/barrel splices, Splitter(s)/Ground Block, "house-wrap" Coaxial Cable runs, Overhead or Underground Drop Cable & all Cable Fittings.
A good Service/Field Tech has updated system maps & can verify acceptable system levels for each LE, AMP & Node. These CATV
Blueprint system maps show every piece of the Network Distribution for the entire CATV
system. Of course, they are broken down in Map Grids. I believe these may now be on a hard drive, which may be on the Field Techs' laptop. Don't quote me on this, though, I left Cox 3+ years ago. In retrospect, I should have stayed. However, the long work hours & fixed work schedule made it impossible for me to Get IT
certified (A+, Network+ & CCNA).
As for the "T3 TIMEOUTS", I would need to know your specific Brand, Make & Model of the Cable Modem. Typically a modem "timeout" occurs when the Modem is unable to establish connectivity with the FDC & RDC.
Sorry to be so long, but you should have all the info possible. You are getting shafted!
I would say switch to DSL, but there is the distance issue & cost! For similar Broadband speed, it would be very expensive. The base DSL price is reasonable, but the taxes are outrages! You can thank Uncle Sam, States & Local for that one. Besides, you must have Basic or Local Calling Plan Landline to have DSL. Make sure to factor in that cost. I don't have a Landline, just SprintPCS. I had a Landline with Qwest for 6 months & never used it! Didn't stop the telemarketers from leaving me messages, though.
