**The BCM6348 combines a G.992.1/G.992.2/G.992.3/G.992.5/ T1.413 ADSL

transceiver and AFE with a high-performance MIPS32 CPU, two 10/100-Mbps Ethernet interfaces, USB (host/device) transceiver, expansion bus interface supporting PCI, mini-PCI, CardBus, and PCMCIA into a single, high-performance chip.**

The embedded ADSL transceiver and AFE implement G992.5 (ADSL2+), G.dmt, T1.413, and G.Lite ADSL, along with G.997.1, G.994.1, I.432 TC layer, dual- latency framing, NTR, and embedded operations channels for remote management of the CPE.
The embedded MIPS32 CPU, with Broadcom-supplied software, controls the ADSL modem, performs high-performance bridging and routing between the ADSL WAN interface and various LAN interfaces, and allows for custom application development with industry-standard EJTAG/Ethernet tool chains and development environments.
A full-featured ATM SAR supports complete traffic shaping, management, and QoS for multiple VCs. The embedded USB (host/device) transceiver, two 10/100-Mbps Ethernet MACs, and one PHY (with auto-MDIX) provide connectivity to PC hosts as well as optional 10/100/1000-Mbps Ethernet switches.
