ABSTRACT:
A combination modem including at least one line connector that is configured for coupling to a transmission medium, analog modem logic that is capable of performing analog modem communications via the transmission medium, digital modem logic that is capable of performing digital modem communications via the transmission medium, a bus interface that enables communication with a computer via an expansion bus of the computer, and processing logic. In this manner a single modem expansion card supports both analog and digital modem technologies using only one slot of an expansion bus of the computer. The analog modem logic may support 56K technologies, such as K56Flex™, V.90, etc., or any combination thereof. The digital modem logic may be according to any type of xDSL, such as ADSL, or U-ADSL, etc. The modem may operate as an analog modem, a digital modem, or as both at the same time with or without a POTS splitter. A single digital signal processor (DSP) located on the modem card may be used to support either the analog or the digital modem communications at any given time or both at the same time. The modem card may be configured as a PCI card for plugging into a PCI bus of the computer.
