DS26401

八路T1 / E1 / J1成帧器

www.maxim-ic.com

概述

该DS26401是一个八进制，软件可选的T1， E1

或J1成帧器。它是由8成帧器/格式化

和一个系统（背板）接口。每个成帧器有

可以映射到任何DS0一个HDLC控制器

或FDL （ T1 ） / SA （ E1 ）位。该DS26401还包括一个

全功能的BERT装置，它可与任何用于

的8个T1 / E1端口，和一个内部时钟适配器

用于创建同步，高频有用

背板时机。该DS26401是通过控制

可以为被配置成一个8位的并行端口

非复用Intel或Motorola操作。

DS26401

八路T1 / E1 / J1成帧器

www.maxim-ic.com

概述

该DS26401是一个八进制，软件可选的T1， E1

或J1成帧器。它是由8成帧器/格式化

和一个系统（背板）接口。每个成帧器有

可以映射到任何DS0一个HDLC控制器

或FDL （ T1 ） / SA （ E1 ）位。该DS26401还包括一个

全功能的BERT装置，它可与任何用于

的8个T1 / E1端口，和一个内部时钟适配器

用于创建同步，高频有用

背板时机。该DS26401是通过控制

可以为被配置成一个8位的并行端口

非复用Intel或Motorola操作。
