产品描述
本系列设备提供1个成帧E1接口和1个V.35接口,能够实现成帧E1到V.35之间的接口转换、用户可利用数据通道速率为N*64Kbps(N=0-32)。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;
◆ 可以在本端强制让对端设备的速率跟随本端(成帧时有效);
◆ 硬件实现31个时隙中任意几个时隙的选择(成帧时有效);
◆ 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;
