San Jose-based DSP Group Inc has extended its chip set for digital telephone answering devices with the D6005, which stores phone messages in solid-state memory rather than on audio tape. DSP says the new storage method increases the reliability of the machines. The D6005 consists of a signal processor to perform speech compression and storage, an ASIC circuit to handle the memory and host interface, a Codec for analogue-to-digital and digital-to-analogue signal conversions and from one to 16 audio-grade dynamic memory chips for message storage. DSP Group says a number of high-volume answering machine manufacturers in Japan and the Far East such as Sanyo Electric Co in Japan and PhoneMate Inc in the US use custom versions of DSP’s D6000 family of Xchip sets. The D6005 can address up to or 26 minutes of storage time and DSP claims this is the largest storage capacity available. The set also offers standard feature such as immediate access to any message in the queue, message repetition, pause and playback, selective message erase and a secret mailbox where access is via a passcode and a directory facility, enabling messages to be left for specific persons. No prices.
