DS33W11/DS33X82 pdf

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.
