ethernet 10M in bus cofiguration

[nba83]

hi
i am designing a bus with 4 node on it(nodes are connected to a shared medium wiring) , i want to use 10M ethernet because it support ethenet bus, i am using Rtl8201 phy layer which support 10M ethernet. when i connect TX+,TX- of the nodes together i 'm not able to transmit anything, because they are not linked. are physical layer chips suitable for ethernet 10M bus configuration? how can i do that? what is the wiring for reaching bus configuration with any 10/100M physical layer chip?
tnx in advanced for any help

There's no defined standard for a twisted pair ethernet bus. Old 10BASE2 coax cable ethernet uses a bus topology.

is it possible to have a bus topology with a phy layer chip which is compliant with ieee802.3 standard? i want to put the phy chips(rtl8201) on the same cable, the speed is not important , only shared medium is important for me.

RTL8201 still supports a legacy 10 MBit interface. You have to design a respective MAU circuit. In case of doubt refer to the example designs for 10 MBit network controllers, e.g. RTL8019.
