当上盖 14和下盖 15安装后， 其箱体内部应该具有良好的密封性， 通 常是气密， 这可以有效保护系统内部的部件。 本发明在下盖 15 与上盖 14 的结合面上开有沟槽， 该沟槽内设有密封条， 当上盖 14与下盖 15安装在 一起时， 该密封条将上盖 14与下盖 15的结合面处密封， 从而达到箱体内 部良好的密封性。

常见的用户板 16包括： ADSL单板、 ADSL2+单板、 VDSL单板、 VDSL2 单板、 普通老式电话业务（POTS , Plain Old Telephone Service )单板、 以太 网单板、 DSL与 POTS合一的单板等等。 从而本发明的系统所支持的功能 主要包括：

R2、 虚拟局域网 （ VLAN, Virtual Local Area Network )、 地址解析协议 ( ARP, Address Resolution Protocol ), 因特网组管理协议 ( IGMP, Internet Group Management Protocol )、 生成树协议 ( STP, Spanning Tree Protocol )、 多生 成树协议（MSTP, Multiple Spanning Tree Protocol ), 链路聚集（ tmnking )、 简单网络管理协议（SNMP, Simple Network Management Protocol )等多种 协议；
系统支持在线升级、 动态数据配置等功能。 另外， 在箱体上可以设计把手 11 , 从而使得该综合接入系统可以用手 提着安装和搬运。
综上所述， 本发明的系统具有无风扇、 全封闭、 一体化的特点。 由于 无噪音， 因此可以安装在居民楼道等地方而对居民的居住环境没有任何影 响； 由于无风扇， 因此设备硬件损坏的概率将大大降低； 由于是一体化的 全封闭设计， 因此可以单独安装在电线杆、 下水道、 墙壁上等多种复杂的 环境中； 由于是一体化的结构， 因此设备安装人员可以直接提着设备到需 要的地方安装， 维护人员在设备故障时直接用新的设备将老设备简单的更 换下来即可， 从而对维护人员的技术要求较低， 故障也能在很短的时间内 排除。
在上述全封闭式综合接入系统的基础上， 本发明还提供了一种全封闭 式综合接入系统的降功耗方法， 釆取用户不工作时对应的用户处理硬件部 分不工作的方法， 进一步降低系统内部的功耗和发热量。 如图 4所示， 本 发明的方法主要包括以下步骤：
步骤 401 , 系统控制板 17对用户板 16上的业务量进行检测。
步骤 402, 在检测的业务量低于预设的下限值（如 20% )时， 系统控制 板 17进入低频工作状态 （如工作频率为正常工作频率的 50% ), 随后在检 测的业务量增大到预设的上限值 (如 30% )时， 系统控制板 17恢复到正常 的工作频率。
进一步的， 在检测到窄带用户板不工作时， 系统控制板 17只保留检测 窄带用户摘机的模块工作， 将其他与窄带用户相关的模块关闭。 该其他与 窄带用户相关的模块包括： 模拟数字转换模块、 从时分交换到包交换的转 换模块、 铃流模块； 那么相应的， 在将其他与窄带用户相关的模块关闭之 后， 如果系统控制板 17检测到有电话接入， 则重新开启铃流模块； 如果系 统控制板 17检测到用户摘机， 则重新开启模拟数字转换模块； 如果系统控 制板 17检测到电话接通， 则重新开启从时分交换到包交换的转换模块。 进一步的， 在检测到宽带用户板不工作时， 系统控制板 17只保留检测 宽带用户是否建链的模块工作， 将其他与宽带用户相关的模块关闭。 该其 他与宽带用户相关的模块包括： 包处理和包交换模块； 那么相应的， 在将 其他与宽带用户相关的模块关闭之后， 如果系统控制板 17检测到有用户建 链， 则重新开启该包处理和包交换模块。
由此可以看出， 通过本发明的降功耗方法， 能够有效降低系统内部发 热部件的发热量， 更有利于控制系统内部温度， 且使得设备硬件损坏的概 率大大降低。
