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.
