50-Pin Telco-to-RJ45
Octopus Cables
The 10BASE-T ‘octopus’ cable breaks out the AT-TS12T or AT-TS24T 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
Allied Telesyn offers a harmonica adapter, Model AT-ADAPT-2. The
harmonica-style adapter shown in Figure 58 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. Make sure that the
pin-out of the adapter you use complies with the 10BASE-T wiring
specification. Refer to Table 8 for the pin-out of the Telco connector for the
AT-TS12T if you order a 10BASE-T harmonica adapter from a wiring
vendor other than ATI.
