DS33Z11

以太网映射器

www.maxim-ic.com

概述

该DS33Z11扩展了10/100以太网LAN

段在HDLC或封装的MAC帧

X.86 （ LAPS ）传输通过PDH / TDM数据

流。串行链路支持bidirectional-

同步互连起来，以在xDSL ，

T1 / E1 / J1 ， T3 / E3 ， V.35 /光端机， OC - 1 / EC - 1 ，或

SONET / SDH支路。

该设备进行存储转发的数据包

以全线速传输能力。内置

承诺信息速率（ CIR ）控制器

提供部分带宽分配到行

速度，增量为512kbps 。该DS33Z11可以

用廉价的外部处理器进行操作，

EEPROM或在独立的硬件模式。

特点
