LAN Port
The LAN port (Ethernet interface) on the MC+1-3 central control module allows the integration of the OpenCom 510 into a company LAN (Local Area Network) with the use of a 10-Mbit hub or switch. In such a configuration, the OpenCom 510 can, for example, act as an IP router for establishing Internet connections.
The Ethernet interface supports transmission rates of 10 Mbits/s and 100 Mbits/s in half duplex or full duplex mode. The transmission rate and mode are selected automatically (Auto Sensing function).
A LAN cable (twisted-pair in accordance with 10BaseT or 100BaseTX) must not be longer than 100 m. Safe operation with 100 Mbits/s requires the use of category 5 cables and sockets. Use a shielded Ethernet cable (STP cable, Shielded Twisted Pair cable).
5.5.1 DSL Port
External DSL modems can be connected via the LAN port. This requires the use of an external switch or hub which connects the output of the DSL modem (NTBBA) to the LAN port of the OpenCom 510. The router will then convert the PPPoE protocol to the TCP/IP protocol of the LAN.
