Chipmaker Infineon Technologies has enhanced the Linux-based software suite it provides with half-a-dozen broadband customer premises equipment (CPE) reference designs. The “Spinacer” suite adds an IMS-based (IP multimedia subsystem) device framework for FMC (fixed-mobile convergence), an optional TR-69 auto-provisioning extension, and support for Infineon VoIP chips with HD (high-definition) sound, the… company said.

Infineon supplies the Spinacer suite with various reference designs, including the recently launched flagship ADSL2+ Residential Gateway (RG) design, as well as ADSL2+ Router, VoIP-Router/ATA, WLAN-Router, and IP-Phone designs. Based on a Linux 2.4 kernel, Spinacer is said to offer the “smallest memory footprint in the industry.”

Infineon said Spinacer's new IMS/FMC capabilities were developed by Comneon, its wholly owned phone chip subsidiary recently in the news for shipping one of the first working single-core Linux phones.

Infineon describes IMS as “an IP-based service platform that enables simple upgrades for new services,” and says the capability will ease the way toward carrier services that interact with a wide variety of devices, including mobile phones, MP3 players, and PDAs. Additional touted features include end-to-end QoS (quality of service) for time-critical applications, and the standardization of presence services such as “buddy-lists” among PCs and various devices.

Additionally, Spinacer is now available with a TR-69 auto-provisioning extension. TR-69 is a DSL Forum specification for remote management aimed at enabling “plug-and-play” CPE that requires no user involvement to configure or maintain.

Finally, Infineon said Spinacer has gained support for HD sound telephony features in some of its VoIP semiconductors. In contrast to “narrowband” telephony limited to the 300Hz to 3.4kHz audio spectrum, HD VoIP supports a wider 50 Hz to 7.0 kHz spectrum, enabling even Isaac Hayes and Tiny Tim to sound themselves.

Christian Wolff, GM of Infineon's wireline access group, stated, “The Infineon SPINACER software with our chip and system reference design solutions [gives] broadband CPE manufacturers a range of added value features.”

Pricing and availability were not disclosed. More details about Spinacer can be found here.
