1.1.2 Integrating the EOC350-TS and EOC350-TA with an STB
In this application, the EOC350-TS and EOC350-TA have the following media types.
• Ethernet. The EOC350-TS receives an Internet feed via an IP gateway and encodes Ethernet
frames on to the coaxial cable connected to the OUT socket. The EOC350-TA decodes the
Ethernet frames for Ethernet devices such as the PC and STB (Set Top Box).
• Coaxial. The EOC350-TS encodes Ethernet frames on to the coaxial cable connected to the OUT
socket. The EOC350-TA decodes the signal from its IN socket for Ethernet devices.

Note: After power up, the Link/Act LED on the EOC350-TS will light up if at least one End
Point (EP) is detected on the Ethernet over Coax (EoC) network. (An EOC350-TA is
called an EP in the Web Configurator.) A dimmed Link/Act LED shows no EP
attached to the EoC network.
Note: The minimum attenuation between an EOC350-TS and the EOC350-TA is 15dB.
Each EOC350-TA is usually connected to the coaxial cable via a cable tap that
contributes more than 20dB attenuation. If you intend to connect the EOC350-TS
and EOC350-TA directly for test purpose, please add an attenuator that exceeds
15dB to the coaxial cable.
1.2 EOC350-TS
The EOC350-TS is an Ethernet over Coax Termination System. The EOC350-TS combines TV and
Ethernet media on to a coaxial cable for distribution to EOC350-TAs.
