The OCT8304 is a 1023 channel full-duplex Features packetization engine for Voice over IP and Voice over AAL2 applications. The design provides * 1000/4000+ voice packetization/aggregation capacity standalone high-density G.711 packetization * Less than 250 sec of latency while enabling integration of off-the-shelf DSPs * Less than 2.5 watts of device power where flexible compression or other requirements * Simultaneous support of IPv4, IPv6, and AAL2 may be added. By combining the OCT8304 with * Full AAL5 support including: Classical IP, LANE (V1/V2), MPOA other Octasic voice processing devices, such as the OCT7102 ADPCM device, or the OCT6100 Series of echo cancellation devices, complete Voice over Packet solutions can be created. * Support for MII (Ethernet), UTOPIA, and POS-PHY network interfaces * 2 network ports * 4096 timeslot H.100/H.110 compliant TDM interface The OCT8304 is highly flexible to allow a single * Support for BLES architecture to address a diversity of require- * Dynamic voice trunking ments. By simultaneously supporting IPv4, IPv6, * Direct interworking with Octasic high-density ADPCM (OCT7102) and echo cancellation (OCT6100 Series) devices and AAL2 at a full 155 Mbps bandwidth, a single board design can be deployed that addresses today's and tomorrow's connectivity demands. Some of the network protocols supported include: Ethernet p/Q, MPLS, and a complete AAL5 implementation (supporting Classical IP, LAN Emulation (V1/V2), and MPOA). To minimize * Silence suppression * Read and write cache for fast accesses * 3.3 V and 2.5V power supply * Packaged in a 608 EPBGA * Full evaluation kit and device API available development efforts, all of these capabilities are accessed through a common, connection oriented API, providing a consistent image for software development.

Octasic provides a developer's kit including: a PCI/H.100 evaluation board, example On the network side of the device, there are 2 schematics, the ORCAD library element, an ports. The primary port is configurable for MII operating system independent API, a remote (Ethernet), UTOPIA, or POS-PHY. The secondary probe tool and example code to exercise the port supports UTOPIA and can be used to device.
