传送和接收 PRI/T1 以及模拟端口的增益设置

增益设置受密码控制,只能由合格的安装人员使用,并且不能提供给最终用户。默认增益设置 0dB 确保符合 FCC 第 68 条 68.308(b)(5) 部分和 TIA/EIA-IS-968 的 4.5.2.5 部分。“通过传输增强用于连接独立注册的设备的端口或其它网络连接端口”。不合格人员调整增益设置可能违反 FCC 规则。在下列情况下,合格人员才能调整这些级别以上的增益设置:

1.进行测量,以确保发送到每个相连网络接口的线路的功率级别不会超过 FCC 第 68 条第 68.308(b) 部分和 TIA/EIA-IS-968 4.5 部分中对特定接口类型指定的最大级别。
2.增益调整不同于默认值时,应当采取措施,以确保终端设备的连接由合格的安装人员控制。
