LAN Port

The LAN port is an 8-pin modular connector that provides a 10baseT ethernet LAN interface. This LAN interface is used for SNMP and TELNET control.

DS3 Interface

The DS3 network interface is a full-duplex circuit provided by two BNC coaxial cable connections. The receive data from the network is connected to the RX (In) connector while the transmit data from the T3SU 300 is connected to the TX (Out) connector.
