TR6442i Continued…

I got one positive response to my post about the Telecast 6442 recently which motivated me to maybe post some of my in-field observations.

  • The 6442, when not linked, will loop the four-wire input to the four-wire output. This can have significant influences on the “side-tone” of the circuit to which the 6442 is connected. If the 6442 is a member of the Camera Conference and suddenly lost its link, maybe do to a fiber-technician cleaning ends, power-loss or whatever, there would suddenly be massive amounts of “loop-back” of the voices on the conference.
  • The 6442 uses an RJ-45 connector wired as USOC. This is really an unsupported standard, though it can be found in the Telex Product line. A 568B wired cable will not work in a Telex environment.
  • The “right” way to connect a four-wire signal in terms of direction can be a bit of a mystery since the MTX and STA switch positions can reverse the Input/Output function of the pins of the RJ-45.

Again, any thoughts or comments to support or debunk my thoughts are welcomed.

    RTS “Telex” does support 568B cabling with the newer Adam M frame , it has a dual format back card for the AIO-16 and AIO-16A analog cards supporting both USOC and 568B , this dual format implementation is also available on the new KP-Series key panels to allow easy connection to both old and new systems.

      Shawn, thank you for taking the time to reply with your clarification. Hearing from a source of accurate knowledge is always helpful. Can you describe the distinction between the AIO-16 and AIO-16A? I am unfamiliar with the A-version.

  2. Shawn says:

    Andrew the new AIO-16A analog card is designed using a FPGA mix engine in stead of the historical ASIC developed by Telex years ago. It is much more energy efficient and draws about 45% less power than the old version card. This allows users to increase the number of digital cards installed in a frame such as the MADI, RVON and OMNEO cards.
