DS33X161

Ethernet Over PDH Mapping Devices

Industry's First Carrier Ethernet Devices to Support Up to 16 T1/E1s or 8 DS3s with Over 400Mbps Throughput


Please check latest availability status for a specific part variant.

Description

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.
