产品描述
本系列设备提供1个非成帧E1接口和1个V.35接口，能够实现非成帧E1到V.35之间的接口转换、用户可利用数据通道速率为2.048Mbps。设备内置环路测试功能，为工程开通和日常维护提供便利。
功能特点
◆ 基于自主知识产权的集成电路
◆ 同时支持自适应的120Ω/平衡和75Ω/不平衡两种阻抗，不用再作设置
◆ 系统经过严格的测试和实用验证，完全符合ITU-T V.35、G.703、G.704等建议；
◆ 提供3种环回功能：E1本端自环（ANA），V.35自环（DIG），令对端V.35自环（REM）；
◆ 有伪随机码测试功能，便于线路开通即可以当一个的2M误码仪来用
◆ V.35接口支持热插拔；支持和DTE或DCE设备互连
◆ V.35工作时钟可支持内时钟、外时钟、线路时钟；
◆ 可选AC 220V，DC -48V、DC +24V，直流电源无正负极之分；
