50-Pin Telco-to-RJ45
Octopus Cables
The 10BASE-T ‘octopus’ cable breaks out the AT-3612T or AT-3624T Hub
50-pin Telco connector to individual RJ45 connectors. This is an ideal method
for connecting into a patch panel in the wiring closet. Patch panels allow for
easy configuration and reconfiguration of house wiring requirements.
When you purchase an octopus cable, ensure that it is wired for 10BASE-T
and that Level 3 UTP is used. This will help maintain 10 megabit data
integrity throughout the wiring system. “Silver Satin” flat cable is out of
specification and should not be used.

Harmonica
ATI offers a harmonica adapter, Model AT-ADAPT-2. The harmonica-style
adapter shown in Figure 51 allows direct conversion from the 50-pin Telco
connector to RJ45 receptacles. There are many different standards for the pin-
out of the harmonica adapter. Ensure that the pin-out of the adapter you use
complies with the 10BASE-T wiring specification. Refer to Table B for the pin-
out of the Telco connector for the AT-3612T if you order a 10BASE-T
harmonica adapter from a wiring vendor other than ATI.
