国际综合布线标准
1.1
目的
这个标准确定了一个可以支持多品种多厂家的商业建筑的综合布线系统，同时也提供了为
商业服务的电信产品的设计方向。
即
使对随后安装的电信产品不甚了解，
该标准可帮您对产品
进行设
计和安装。在建筑建造和改造过程中进行布线系统的安装比建筑落成后实施要大大节省
人
力物力财力。
这个标准确定了各种各样布线系统配置的相关元
器件的性能和技术标准。
为达
到一个多功能的布线系统，已对大
多数电信业务的性能要求进行了审核。业务的多样化及新业
务的不断出现会对所需性能作
某些限制。用户为了了解这些限制应知道所需业务的标准。
1. 2
相关的标准
这个标
准是一系列关于建筑布线中电信产品和业务的技术标准之一。
本文连同相关的标准
满足了电信行业发展企业结构的需要。
为电信服务的商业建筑标准
(EIA/TIA-569)
(Ref
B1.3)
和住宅及小型
商业区综合布线标准
(EIA/TIA-570)(Ref
B1.2)
。
1. 3
标准的说明
标准分为强制性和建议性两种。所谓强制性是指要求是必须的
，而建议性要求意味着也许
可能或希望。（这两种概念将在本文中交替出现）。
强制性标准通常适于保护、生产、管理，
兼容
：它强调了绝对的最小限度可接受的要求，建议性或希望性的标准通常针对最终产品。在
某种程度上在统计范围内确保全部产品同使用的设施设备相适应体现了这些准则。另一方面，
建议性准则是用来在产品的制造中提高生产率，无论是强制性的要求还是建议性的都是为同一
标准的技术规范。建议性的标准是为了达到一个目的，就是未来的设计要努力达到特殊的兼容
性或实施的先进性。
在本文中。
图表中的注释是标准的一个正式的部分，
是用来提供有益的建
< br>议。
其他文件的引用除了特殊说明外都指的是标准的最新修定本。
该标准是现行使用的，文
中所涉及的标准都是服从修订本的，而
且通过在网络的工作过程及终端设备的布线技术中得到
了验证。

水平布线
4.1
概述
水平布线是综合布线结构的一部分
，它从工作区的信息插口一直到管理区，内有工作区的
管理区，水平电缆的终端利跳线架
。
注：用水一词是因该布线系统非常常典型，都是沿大楼的<
/p>
地板和顶棚布线的。
完成水平布线的设
计后，
就要考虑以下的日常业务和系统
（所列并不完全〕
。
（
1
）语音通信业务
（
2
）室内交换设备
< br>
（
3
）数据通信
（
4
）
局域网
为了满足当今电信
的需求水平布线应便于维护和改进适应新的设备和业务变化。水平布线需要有大量的用于大楼
的专用电缆。当大楼落成后水平布线：：主于布线困难得多。为了适应变化，对时间、效率嗷<
/p>
术的要求很高。另参）水平布线会干扰工作人员的工作，所以水平缆线的类型和设计的选择
对
于大楼布线的设计来说就相当重要了。为避免和减少因需求变化带来水平布线的变动，
应考虑
水平布线应用的广泛性。
同时
还要考虑水平布线离电气设备多远会造成高强度的电磁干扰。大
楼内的机械设备如发电机
和变压器以及工作区的复印设备都属于这类电气设备。

拓扑
水平布线如图附
4.1
所示是星型拓朴结构每个工作区的信息插座都要和管理区相连。
附
4.1
水平布线的
拓朴和距离
水平布线是同一类型电缆的不同形式的转接点。
注
1
：为形成
母线
和
环状
拓扑，设备间的布线被认为是主干布线的一部分，在<
/p>
5.2.3
中将讨论相邻管理区
的直接连
接。
注
2
：
些网络和业务在水平布线的信息插座处需要电子器件
（如，
阻抗匹配器件〕
。
这些电子器件不能作为水
平布线的一部分安装。如果需要，它们只能倭接在插座外部，起到水
平线的作用。
4.3
水平距离
图附
4.1
中与媒体间最大的水平距离为
90m
< br>。电缆长度等于设备媒体终端到工作
区插座的电缆长度。
注：从插座到工作区允许有另外
3m
的
距离。跳接箱的跳线和插接线的长
度限制在第
12
章的说明内。

接地方法
除了其他们关标准
有更严格的规定外，接地方法必须符合
NEC
要求。
接地系统一般是商业
建筑楼内保护专用信号或通信布线系统不受干扰的一个完整部
分。为了保护强电环境中的
人员和设备接地系统必须减少对通信布线系统的电磁干扰的影响和
由它所带来的电磁干扰
的影响。
错误的接地装置会产生感应电压破坏其通信电路。
在符合电
气标准的同时还必须遵守设备厂家的接地规程和要求。
专用数据和通信网的接地标准要
优于国
内和当地的标准。
在设计系统时要考虑以下因素
（
1)
确保
安装遵守正确的操作规范。
(2)
保证每一个设备室有一适当的接地口。
(3)
保证接地装置适用于跳接跳
线架，接插件机架，电话和数据设备以及维修和测量设备
。

主干布线
5.1
概述
主十布线的作用是提供管理区之间
,
设备之间和综合布线系统结构中如靠入口设备的相互连
接
(
如图
1.1).
主
干布线由设备间有人口设备所需的传输媒体中间和主跳线箱，
机械终端组成通信
设备的相互连接
.
计算机、设备间、分界点也许
分布在不同建筑内，主干布线就是建筑物间的传
输媒体。
很显然
，对于一个永久性的综合布线系统预先安装全部主干线是不可能也是不经济的。有
效地安
装主干线一般希望分一倒七个设计阶段，每个阶段要
3~10
年
。在每个阶段不能安装其他
的布线，保证适应业务需求的增长和变化。每个阶段的长短依
使用单位的稳定性和变化而定。
在每个设计阶段开始之前，需要现划一下该阶段所需的最大规
模的主于布线总最，对每个
管理区、设备间和不同类型的服务，应该估计一下在设计阶段
大规模连接的总量。为铜或光纤媒
体进行充分的主干布线以便直接或通过辅助的电子设备
满足大量的接连。
在设计线路和支持主
干电缆结构时应注意避开发动机和变压器等产生的电磁干扰的地方。
5.2
拓朴
5.2.1
星型拓扑
主干布线要使用如图
5.1
所示的常用的分层星型拓
扑。
除了在
5.2.3
中所注的
外）
,
在每一管理区
里都有到一主跳接或内跳接再到主跳接的布线
.
在主干布线中仅有两种常用
的跳接
.
< br>两个管理区间的相
互连接要通过三个以下的跳接箱
,
单一的跳接必须达到主跳接
.
一个单
独的主干布线的跳接箱
(
主交叉连接
)
可能满足交叉连接的需要。主干布线的跳接可
在机柜、
设备室或入楼设备内。
注
1<
/p>
：由于该拓扑的兼容性和稳定性能满足不同的使用要求，它已经作为符合标准的拓扑被
采用，对于两种标准的跳接箱的限定是为了限制老系统的信号衰减和加强管理。
注
2
：星型拓扑适用于传输媒体的专
用单元，像专用光纤，双绞线对或同轴电缆。根据现场
和设备室的实际特点，连在不同设
备终端的传输媒体是一段距离中同一电缆的部分。在这个距离
中也可以使用专用电缆。图
14.1
是主干布线的实例
.
注
3:
桥接配线不属下王丁布线。
5.2.2
非星型结构的调整
环型网，总线或树状网络的非星型结构的系统可通过应用作正确的相
互连接，电了器件或跳接箱和机柜中的转接器如图附
5.1
所示
的拓扑来调整。图
5.2
、图
5.3<

、
图
5.4
说明
了怎样用星型拓扑来调整总线，环型和树状结构。
5.2.3
两个管理区间的直接连接
如果希望对
总线、树型或环型网络结构有所要求，就允许两个
管理区的直接连接，它是对
5.2.1
中的基本星型号拓扑连接的补充。
<
/p>
为了适应
IEEE802.3
的应
用，当
50

选择
媒体
由这个标准限定的主下布线能满足不同用尸的衍求。
根据应用特点，
需要选
择传输媒体。要考虑
以下因素
:
(1)
业务的灵活性
(2)
主于布线的使用寿命
(3)
地区范围和用户量
商业大楼的用户刺
信息业务的需求各不们同。
对于主于布线设计的全
面考虑是从其
可预见性到不可
预见性
.
无论可能与否我们首先要满足不同的业务需求，
将相近的
< br>业务如话音、显示、终端、局域网和其
他的网络连成一
起且很有益的每一部分的不同业务种类
要进行划分并做好计划。
当不可舢见时考虑改动主干布线是最坏的打算不可预见性越大就越需
要要求主于布线的灵活性。
每条可识别电缆都有其特点和
作用，一种类型的电缆也许不能满足
同一地区所有有用户的需要。在主干布线中使用多种
媒体是必要的，这时不同的媒体就要使用同
种设备结构才能用于主跳线箱、终端和大楼间
的入楼设备等。
5.5
主干布线的距离
5.5.1
管理区到主跳接箱
管理区的机械终端
到主跳楼箱的最大距离如图
5.5
所示
.
通常将
主跳接箱放在场地的中部附近使电缆的距离最小
,
安装超过了距离局限就要被划分成几个区
域、
每个区域曲满足距离要求的主干布线来支持。
注
1:
在每个区域间的相互连接如果超出了这个标准范
围
,
通常要租用设备或借鉴应用广泛
的
新技术来解决。
注
2:
某
些特殊的系统超过了这个最大距离不能正常运行
,
为了支持这样
的系统在主干布线
的传输媒体中加入中继器是必要的
.
5.5.2
主跳接箱到人楼设备
当有关分界点的
位置的常规标准允许时，
入楼设备到跳接箱的
距离应包括在总距
离中
（见
9.3
）
.
所用媒体的长度和规格要作记录并满足业务提供者的要求
（见
附录（
C
）。
注
1:
当
T
C
到
IC
的距离小于最大距离时，
IC
到
MC
的光纤
距离可相应增加。但
TC
到
MC
的
总距离不能超过
2000m(6560ft
).
注
2:
当
T
C
到
IC
的距离小于最大距离时
,IC
到
MC
的
UTP
电缆的距离可相应增加
,
但
TC
到
MC
的总距离不超过
800m.
5.5.3
跳接箱到电信设备
直接与主跳接箱或中间跳接箱连接
的设备应使用小于
30m
长的转接电缆。
5.6
接地方法
接地应符合
MC
的标准和实施要求除非有其他更严格的要求。
接地系统通常是专用信号的
一个主要部分或是它们所保护的综合布线系统
的一个主要部分。为了保
护人员和设备免遭高压
的危害，接地系统应减少刘布线系统的电磁干扰的影响或由布线系统带来的电磁
干扰的影响，
不正确的接地会产生感应电压而干扰其他通信
电路。
当符合电气标准时
,
我们要遵守设备厂家的接地说时和要求。专用数据和通信网的接地要求
可能比美
国内的有关要求高：
当设计接地系统时，要考虑下列因素
:
（
1
）保证安装符合正确的操什规程。
(2)
保证管理区、设备室和人楼设备有正确的接地入口
.
(3)
保证接地适用于跳接箱
,
插接
架
,
电话和数
据设备以及维修和测试设备。

概述
管理区是为与布线系统州关的大楼设备而设置的一个空间。<

每座大楼至少要有一个管理区或设备
室（第八章）．数量不限。下
而是管理区的三种应用：

．
1
水平／主干连接
管理区内有部分主干布线和部分水平布线的机械终端，为无源（交叉
连接〕或有源或用于
两个系统连接的设备提供设施（空间、电力、接地等）。
7
．

．
2
主干布线系统的相互连接
管理区内有
上干布线系统不同邢分的中间跳接箱和主跳接箱，
为无源或有源设备或两系统的互连或主
干布线的更多部分提供设施（空间、电力、接地等〕。
7
．

．
3
入楼设备
管理区设有分界点和大楼间
的人楼设备，为用于分界点相互连接的有源或无
源设备、楼间人楼设备或
通信有线系统提供设施。

概述
设备至是用来将建筑内的通信系统和邵分布线系统的机械终端放置在一起。
< br>它与管埋区的区别在
于
装有设

概述
入楼设备构成了通柱大楼的通信业
务，
包括到大楼墙而直到人口处的输入点并有与坐落在寸范围
内的其他大楼栩连的主干电缆。

内部建筑的人楼设备
中间入楼设备起
到了连接内部主于布线和中部中于布线的作用。它
为符合标准的金属电缆提供电气
保护。

网络接地点
网络接地点是本地通信部
门的通信设备和用户终端的通信系统布线及设备之间
的连接点（
RefB1.38
）
9.3.1
物理接地点
通信部门提供业务的接地
方式是标准中记录的转接装置或在目录中提到的
或工业标准中规定的方
< br>
为了系统的安装，确定准确的接地点要同业务提供者或厂商协商。
9
．

接地点的位置
在单一用户的大楼中，
接地点在保护装置的
12
英寸范围内或元保护装
置的地方它们一般在通信部门设备到大楼的
12
英寸范
围内，在多用户大楼中通信部门要为接地点限
定起码的几个点的屡人法规。否
则，大楼的房主可自行规定接地点的位置可以设置一个单独的接地
点也可以在每个用户的办公地点设一
个分界
点。
这样从布线到用户办公地点就会超过
12
< br>英寸。
在
