The DS33X162 family of semiconductor devices extend 10/100/1000Mbps Ethernet LAN segments by encapsulating MAC frames in GFP-F, HDLC, cHDLC, or X.86 (LAPS) for transmission over PDH/TDM data streams. The devices support the Ethernet over PDH (EoPDH) standards for the delivery of Ethernet Access Services, including eLAN, eLINE, and VLAN. The multiport devices support VCAT/LCAS for dynamic link aggregation. The serial links support bidirectional synchronous interconnect up to 52Mbps over xDSL, T1/E1/J1, T3/E3, or V.35/Optical.

The devices perform store-and-forward of frames with Ethernet traffic conditioning and bridging functions at wire speed. The programmability of classification, priority queuing, encapsulation, and bundling allows great flexibility in providing various Ethernet services. OAM flows can be extracted and inserted by an external processor to manage the Ethernet service.

The voice ports of the DS33W41 and DS33W11 easily connect to external codecs for integrated voice and data service applications.

Product Detail

The DS33X162 demo kit (DK) is an easy-to-use evaluation board for the DS33X162 Ethernet-over-PDH device. The demo kit contains an option for either T3/E3 or T1/E1 serial links. All serial links are complete with line interface, transformers, and network connections. Maxim's ChipView software is provided with the demo kit, giving point-and-click access to configuration and status registers from a Windows®-based_PC.

On-board LEDs indicate receive loss-of-signal, queue overflow, Ethernet link, Tx/Rx, and interrupt status.
