Abrégé

A RolP expansion device (210) can be used to expand the amount of available radio ports (310) at a RolP gateway. The RolP expansion device (210) includes a microcontroller (340) for relaying audio and signaling information between the USB bus of a host device (e.g., a RolP gateway device or computer) and a plurality of radio ports (310). According to some embodiments, the RolP expansion device (210) may include serial (330) and/or general-purpose input/output (GPIO) ports (320) to provide additional functionality.
