ABSTRACT:
An integrated I/O interface for a communication terminal, connectable with an external analog communication device and with an external digital communication device, includes an I/O interface subsystem having analog and digital arrays, a first connector for connecting the I/O interface subsystem to a digital processor for the terminal, and a second connector for connecting the I/O interface subsystem to both the analog communication device and the digital communication device. The digital array and the analog array including a CODEC are mounted on a platform carrier on the I/O interface subsystem board. The second connector is a single connector having pins for transmitting the analog signals, pins for the digital signals, a pin indicating whether the analog or digital mode is selected, and a pin indicating which external communication device is selected. The second connector also has common EMI and EMP protective filter circuits incorporated therein to protect the I/O interface subsystem.
