Assume that the cost of communications equipment and facilities is as follows:
8-channel TDM at $$\$ 500$$
28800 modem at $$\$ 400$$
leased line city A to city B $$\$1000/month$$
If twelve 2400 bps terminals are located in city A and the computer is located in city $B$, draw a schematic of the multiplexing network required to permit the terminals to access the computer, assuming each terminal can be directly connected to the multiplexer. What is the cost of this network for one year of operation?
