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.

DS33X162系列的半導(dǎo)體器件擴展了10/100/1000Mbps以太網(wǎng)LAN，按照GFP-F、HDLC、cHDLC或X.86 (LAPS)格式進行MAC幀壓縮，以PDH/TDM數(shù)據(jù)流進行傳輸。器件支持以Ethernet over PDH (EoPDH)標(biāo)準實現(xiàn)太網(wǎng)接入服務(wù)，包括eLAN、eLINE和VLAN。這些多端口器件支持動態(tài)鏈路集合的VCAT/LCAS。串行鏈路支持雙向同步互連，在xDSL、T1/E1/J1、T3/E3或V.35/光纖之間實現(xiàn)高達52Mbps傳輸速率。

器件以全速傳輸能力實現(xiàn)數(shù)據(jù)包的保存和轉(zhuǎn)發(fā)，并具有以太網(wǎng)傳輸調(diào)理和橋接功能。分類、優(yōu)先級隊列、包裝、和打包等功能的可編程能力為多種以太網(wǎng)服務(wù)提供了極大的靈活性。通過管理以太網(wǎng)服務(wù)的外部處理器可以提取和插入OAM流。

DS33Z41和DS33W11的語音端口可以很方便的連接外部codec，用于集成語音和數(shù)據(jù)服務(wù)應(yīng)用。
