Assume that the requirements of Question 6 are modified, resulting in all twelve terminals being located beyond cabling distance of the multiplexer. Assume the following cost of communications equipment and facilities:
$$
\begin{array}{ll}
8 \text { position rotary } & \$ 50 / \text { month } \\
\text { telephone lines at } & \$ 30 / \text { month } \\
2400 \text { bps modems at } & \$ 30
\end{array}
$$
Draw a revised schematic of the multiplexing network.What is the cost of this network for one year of operation?
