Default Hardware design questions

Hi all,
I have 2 questions about hardware design.

1. I'm designing a one in two or more output circuit. Just to verify - the input whould be terminated to 120 ohms and each output should have the biasing network?

2. Using the 75176 IC's, the output of each IC "R" (receive data) outputs will need to 'simulate' a collision merging all of the data streams, (for the discovery mode). My intention is to connect a 100ohm resistor to each output merging into a single bus-would this be an good approach? Or would a multi input AND gate work?

Thank you in advance, any assistance or recommendations would be appreciated.
