产品描述
本成帧E1光猫提供1个E1接口和1个光接口,能够实现E1到光之间的接口转换、速率转换和E1时隙提取功能。成帧模式下,用户可利用数据通道速率为n*64k任意时隙可以设置。
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 G.703、G.704等建议;
◆ 硬件实现31个时隙中任意几个时隙的选择(成帧时有效);
◆ 提供3种环回功能:光口本端自环(ANA),E1本端自环(DIG),命令对端E1向本端环回;
◆ 提供伪随机码测试功能(PATT),相当于内置误码仪,便于线路开通测试;
◆ 可选AC 220V,DC -48V、DC +24V,直流电源无正负极之分;
