DS33X81 pdf,DS33X81 datasheet

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.
Applications
Bonded Transparent LAN Service
LAN Extension
Ethernet Delivery Over T1/E1/J1, T3/E3,
OC-1/EC-1, G.SHDSL, or HDSL2/4

DS33X162系列的半导体器件扩展了10/100/1000Mbps以太网LAN，按照GFP-F、HDLC、cHDLC或X.86 (LAPS)格式进行MAC帧压缩，以PDH/TDM数据流进行传输。器件支持以Ethernet over PDH (EoPDH)标准实现太网接入服务，包括eLAN、eLINE和VLAN。这些多端口器件支持动态链路集合的VCAT/LCAS。串行链路支持双向同步互连，在xDSL、T1/E1/J1、T3/E3或V.35/光纤之间实现高达52Mbps传输速率。

器件以全速传输能力实现数据包的保存和转发，并具有以太网传输调理和桥接功能。分类、优先级队列、包装、和打包等功能的可编程能力为多种以太网服务提供了极大的灵活性。通过管理以太网服务的外部处理器可以提取和插入OAM流。

DS33Z41和DS33W11的语音端口可以很方便的连接外部codec，用于集成语音和数据服务应用。
