CLI: calling line identity
CPS: calls persecond
ACD: Average
Call Duration measures the average length of time a call remains connected.
PDD: Post
Dial Delay measures the amount of time after the user dials a phone number till the time the user hears a ring-back tone.
LRN: Location
Routing Number,a unique 10-digit telephone number assigned to each switch. The LRN approach made it possible to introduce LNP without radically changing the Public Switched Telephone Network.
A Location Routing Number (or LRN) is a unique number that uses the format of a telephone number, but actually represents an entire telephone switch through which multiple telephone numbers are routed. The assignment of a local routing number to telephone numbers allows for local number portability.
它是存储在服务控制中心的数据库中的10进制数字,为本地电话局识别连接到的端口。
在美国,定位寻址号(LRN)是存储在被称为服务控制中心(SCP)的数据库中的10进制数字,它为本地电话局识别连接到的端口。LRN这种技术旨在实现本地号码可移植。使用LRN,当一个电话号码被呼叫时,本地电话局会搜索寻址数据库,通常是SCP,查找与署名用户相关的LRN。
ANI: Automatic number identification. 自动识别呼叫者电话号码
CLI: Calling Line Identification in Europe like ANI.
Caller ID (caller identification, CID), also called calling line identification (CLID), calling number delivery (CND), calling number identification (CNID) or calling line identification presentation (CLIP).Caller ID allows the person being called to see the number (and sometimes the name) of the person calling them, when they have the correct equipment to receive the callerid information. Caller id is often an added value (i.e extra cost) service from your telco. You can usually withhold sending of the caller id on outgoing calls by dialling a special code before the number.
Caller ID (caller identification ,CID), 也被叫做Calling line identification (CLID)或者 calling caller ID(CNID), 它是一种电话服务,在模拟电话、电子电话系统、和符合VoIP(Voice over Internet Protocol)等的应用中经常见到。它可以在通话时把自己电话号码传给接电话的人,显示的时间段是电话响铃,也就是通话建立,但是还没有被接电话的人拿起电话的那段时间。也就是来电显示。
有的时候,Caller ID还包含姓名信息。当然,这个涉及到隐私问题,需要本人同意才可。Caller ID可能会产生一些问题,比如存在Caller ID欺骗的可能性。
DID: means Direct Inward Dialing. It is a number (or a range of numbers) which can be used to receive calls. Voxbone's DID product name is VoxDID and refers to geographic or national telephone numbers.
DDI: Same as DID. In the USA people use the term DID (Direct Inward Dialing) whereas in Europe people use the term DDI (Direc Dial-In).
What is CPC and what does it stand for?
CPC stands for Calling Party Category. It identifies the call origin and enables you to benefit from a differentiated price structure, especially for toll-free numbers. ordinary or cellular or payphone
DNIS: DNIS stands for Dialed Number Identification Service and can allow you to route the call based on the dialed number.
ring back
回铃音是电话系统中当一个主叫拨通一个号码听到的断续的声音,而此时线路的远端将收到一个响铃的信号。它可以由被叫用户或主叫用户的服务交换产生,而不是由被叫设备产生。回铃音也被称作是audible, audible ringing tone, ringback tone以及ringtone。
  回铃音的出现并不一定意味着远端设备已被触发。比如说,如果线路和远端电话线都处于正常的工作状态,但是被叫用户并没有连着电话机或其它设备,主叫用户是仍然可以听到回铃音的。而没有出现回铃音则一般代表远端线路还没被连上。
  当延迟自动呼叫系统呼叫远端设备时,有时也用术语回铃音来指代主叫收到的响铃信号。
象移动的彩铃,别人打你电话在接通之前听到的声音。电信(包括固定电话)和联通都有相似业务。
A ringback tone (or ringing tone) is an audible indication that is heard on the telephone line by the caller while the phone they are calling is being rung. It is normally a repeated tone, designed to assure the calling party that the called party's line is ringing, although the ring-back tone may be out of sync with the ringing signal.(http://en.wikipedia.org/wiki/Ringback_tone)
LEC: 本地交换电信局.本地交换局是LEC的本地电话总局。从家庭或商务终端连接到本地交换局。本地交换局还连接到其他的交换电信局,或者是内部交换电信局,例如长途交换电信局AT&T,MCI和Sprint。http://www.elecfans.com/baike/tongxingjishu/jichuzhishi/20100306180308.html
LEC(本地交换电信公司)在特定的授权的服务区域(基本是业务垄断)运作,该区域称为LATA(本地接入和传输区域)。LATA的边界定义了本地业务终止和长途业务开始的界线。一个LATA具有一个或多个电话区号。LEC可以是现任电信公司和竞争性接入提供商之一。本地电信公司通常在同一LATA中具有若干交换局(称为中心局或CO)。IXC(长途电信公司)是在任何在LEC之间提供业务的长途电信业务提供商,如美国的AT&T、MCI或US Sprint。 IXC要求LEC提供IXC入网点(接口)。IXC所使用的通信设备有光缆、地面微波塔和卫星微波系统。大多数长途电话除了需要由长途通信公司的骨干网传输之外,在两端还要使用LEC连接(但长途通信量大的一些用户能直接连接他们的IXC入网点)。任何超出一个LATA区域的通信都被认为是长途通信,并且由长途电信局(IXC)处理。长途电信局包括AT&T、MCI和US Sprint等公司。法律要求LEC必须为IXC提供一个访问点(point-of-present,一种接口)。IxC拥有的通信设备包括光纤缆线、基于地面的微波塔和基于卫星的微波系统。
Local access and transport area (LATA) is a term used in U.S. telecommunications regulation. Generally, a LATA represents an area within which a divested Regional Bell Operating Company (RBOC) is permitted to offer exchange telecommunications and exchange access services. Under the terms of the MFJ, the RBOCs are generally prohibited from providing services that originate in one LATA and terminate in another.
CIC,Circuit Identification Code的缩写,在通信系统中的中文解释一般为“电路识别码”,在电信网络作互连互通时经常用到.
其中CIC的最低5位表示分配给话路的实际时隙号, 其余7位 表示起源点和目的点的PCM系统识别码。
ILEC: incumbent local exchange carrier 传统的本地固网交换运营商(CLEC未出现前就存在的).传统供应商指的是在引入电信竞争法前以垄断方式经营的公司。包括大型公司和小型公司。
