Compact modem system suitable for a notebook or other small computer

摘要

By the connection of a first subcard (26) to a main modem board (10), the modem system is customized to use an external data access arrangement (DAA) (32), while the connection of a second subcard (36) instead of the first customizes the modem system to use a built-in DAA (24). The subcards connect to the main modem board through a single interface connector (18). The first subcard includes a MiniDin connector (28) for connection to the external DAA, while the second subcard includes an RJ11 connector for direct connection to a telephone line. This mechanical arrangement results in a small, compact modem system suitable for use in a small computer.
