电信专⽤名词基础名词ISP：Internet Service Provider，互联⽹服务提供商。
即向⼴⼤⽤户综合提供互联⽹接⼊业务、信息业务、和增值业务的电信运营商。
ICP：Internet Content Provider，互联⽹内容提供商，向⼴⼤⽤户综合提供互联⽹信息业务和增值业务的电信运营商。
宽带：将⽹络接⼊速度为64Kbps(最⼤下载速度为8KB/S)及其以下的⽹络接⼊⽅式称为“窄带”，相对于宽带⽽⾔窄带的缺点是接⼊速度慢。
对于⾼于2Mb/s的通信业务，如帧中继业务、视频点播、ATM业务、TV会议等称为宽带通信业务。
ATM：异步传输模式PSTN：Public Switched Telephone Network，公共交换电话线。
DSL：Digital Subscriber Line，数字⽤户线路，以铜质电话线为传输介质的传输技术组合，包括HDSL、SDSL、VDSL、ADSL和RADSL 等。
ADSL：Asymmetric Digital Subscriber Line，⾮对称数字⽤户线路，上⾏和下⾏带宽不对称。
ADSL技术采⽤频分复⽤技术把普通的电话线分成电话、上⾏和下⾏三个相对独⽴的信道，从⽽避免相互之间的⼲扰。
只需在电话线两端加装ADSL设备即可。
拨号上⽹：最早的上⽹⽅式，只需要⼀台电脑，⼀个外置或内置的modem和⼀根电话线，再向ISP提供商申请⾃⼰的账号，拥有⾃⼰的⽤户名和密码后，通过拨打ISP的接⼊号连接到internet。
⽬前国内拨号上⽹的⽤户基本都是使⽤基于PPPoE协议的ADSL。
PPPoE：Point-to-Point Protocol Over Ethernet，以太⽹上的点对点协议，是将点对点协议（PPP）封装在以太⽹（Ethernet）框架中的⼀种⽹络隧道协议。
由于协议中集成PPP协议，所以实现出传统以太⽹不能提供的⾝份验证、加密以及压缩等功能，也可⽤于缆线调制解调器（cable modem）和数字⽤户线路（DSL）等以以太⽹协议向⽤户提供接⼊服务的协议体系。

电信术语(1)
电信术语(1)序号中文英文术语解释缩写来源1 光时域反射法（OTDR），向后散射法OPTICAL TIME DOMAIN REFLECTOMETRY，BACKSCATTERING TECHNIQUE 靠光脉冲传输通过光纤，测量返回输入端的散射光与反射光的合成光功率的时间函数，从而测得光纤特性的一种方法。
注：这种方法在估算均匀光纤的衰减系数，检查光纤的光学连续性，确定故障点位置以及其他局部损耗是很有用的。
OTDR GB/T 14733.12-932 开放系统互连（参考模型） OPEN SYSTEMS INTERCONNECTION (REFERENCE MODEL) 电信网与由电信网提供的电信业务之间和各种关系用七个规约层加以编排的体系结构。
OSI GB/T 14733.11-933 工作频率(OWF) (FOT) optimum working frequency 在给定时间，经常是一个月的90%的规定期间，被工作MUF超过的频率。
OWF GB/T 14733.9-934 OSI/网管论坛 OSI/Network Management Forum 由AT&T、BT、MCI、NTT、北方电信、DEC等公司组成，在OSI RM（七层模型）上开发有关规程。
Forum (论坛)在此指由民间团体和公司组成的组织，对某一行业发表具有一定性的建议。
OSI/NMF5 在线服务提供者 Online Service Provider 只向其客户提供客户所需信息内容的公司。
OSP6 地线复合光缆 (又称光纤架空地线) Optical Power Grounded Waveguide 电力传输线路中地线中含有供通信用的光纤单元。
该种光缆做到两全，即地线的电性能和机械性能不因设置了光纤而受到损害，光纤单元也要适当地受到保护而不致损伤。
有铅骨架型、不锈钢管型以及海底光缆型等几种。
OPGW7 操作系统功能或协调功能 Operations System Function or Mediation Function 电信管理网（TMN）中的一种实体。
