Note: This encryption "Y" cable connects a Polycom VSX 7000 or 8000 or a Polycom HDX 7000 or 8000 with a VHDCI68 female interface to an RS-366 device with a DB25 female interface and a KIV-7M Red device with a VHDCI68 female interface. The "Y" cable legs exit the Common backshell and are jointly covered for the first three inches for extra strain relief. Most applications require a PVC jacket. Stonewall also offers a plenum rated jacket and a Low Smoke Zero Halogen (LSZH) jacket. See Jacket Types sidebar for more information.
