The BCM6358 combines an ADSL2+ transceiver and AFE with a high-performance VIPER MIPS32 CPU, hardware ATM SAR, dual 10/100 Ethernet, dual USB 2.0 hosts and 1.1 device, multichannel 8/16-bit TDM/PCM bus, 16/32-bit parallel expansion bus supporting CardBus, PCMCIA, and mini-PCI into a single high-performance monolithic device.

   The ADSL2+ transceiver delivers up to 29 Mbps downstream and 3 Mbps upstream, enhanced QoS for IPTV video, dual-latency framing, and embedded operations channels for remote management of the CPE. Powered by the VIPER MIPS32 CPU and supplied software, the ADSL2+ modem performs wire speed bridging and routing between the WAN and the various LAN interfaces, and supports custom application development with industry-standard EJTAG debuggers, tool chains, and development environments.
