1. A device comprising:
- a digital signal processor comprising;
a plurality of serial ports, a plurality of general purpose input-output ports, and a stream processing operating system to manage operation of signal processing by the digital signal processor;
an audio portion to receive audio data comprising one or more audio codecs; and
a modem portion to receive communications data comprising;
one or more modem codecs, and a data access arrangement coupled with at least one of the plurality of the general input-output ports, and coupled with one or more of the modem codecs, the data access arrangement to transmit ringing information from a signaling portion of the communications data to the digital signal processor via the at least one of the plurality of general input-output ports, and to transmit a non-signaling portion of the communications data to the one or more modem codecs.
