ABSTRACT:
A multiline modem system provides to a computer connection a plurality of lephone lines for transmitting and receiving digital computer data at throughput rates that exceed those of single line modem systems. The system determines the number of available telephone lines, sequences through a series of telephone re-dials, and acknowledges all connections. When the last connection is verified, the system is on-line and data transfer can begin. The system described uses state-of-the-art components and meets FCC Part 68 requirements for connection to the switched telephone network.
