A modem and associated method with both an RS-232 interface and a USB interface connects to a host. The modem detects which of the two interfaces is connected to the host and determines an appropriate data path. For connections to the USB interface, data is routed through a USB processor and over a serial link to the modem processor responsible for modem communications and the transfer of modem data to the POTS. The serial link between the USB processor and the modem processor is used to transfer both modem data and processor communications. A plurality of control lines are used to indicate the type of data being transferred over the serial link. For RS-232 connections, the modem data is transferred to the modem processor. Thus, one modem device may be used for either USB or RS-232 connections.

A speaker-phone assembly includes a speaker assembly, a microphone and an outer shell. The speaker assembly includes an upper lid, a bottom cup, and a speaker. A gasket may be positioned between the lid and cup, a C-shaped gasket may be positioned around the rim of the speaker to isolate the speaker from the lid. A plurality of brackets including gaskets extend from the cup and are received by posts extending from an interior portion of the outer shell to isolate the speaker assembly from the outer shell. A microphone stand having an inner region connected to an outer region by at least one web portion isolates the microphone. The microphone is positioned upright and in a plane substantially perpendicular to a plane which includes a rim of the speaker.
