10-NetAn original local area network invented by a company called Fox Research, Dayton, OH. 10-Net is a baseband, Ethernet CSMA/CD peer-to-peer LAN running on one twisted pair at one megabit per second. It is easy to install and has many advantages. It's also slow. Very slow. And it's no longer being made. See Ethernet.

最初的局域网是由一个叫Fox Research, Dayton, OH的公司创建的。10-Net是一个基带，以太网CSMA/CD对等局域网，在一股双绞线上以1Mbps的速度传输的。这种网络易于安装，有很多优点。但是传输速度很慢，非常慢。已经不再使用了。参见Ethernet。

10/100An Ethernet/Fast Ethernet designation, referring to having both 10Mbps and 100 Mbps on the same port.

一种以太网/快速以太网的代称。指在同一端口上同时具有10Mbps和100Mbps传输速率。

100 Base TSee 100Base-T. T stands for Twisted pair.

参见100Base-T。T代表双绞线。

100 Test LineA Nortel Networks' switching term. The 100 test line, also known as a quiet or balanced termination, is used for noise and loss measurements. The S100 provides a quiet termination for noise measurements only. In this 100 family, there are the T100, S100 and N100 tests. The N100, a more recent version of the test, also includes a milliwatt test (i.e., a 102 test line) and therefore can be used for far-to-near loss measurements. The T100 is used when the equipment at the terminating office is unknown. When the T100 test line is performed, a two-second time-out is introduced to detect the presence or absence of a milliwatt tone. If the T100 test detects the milliwatt tone, it executes the N100 version of the test; otherwise, the S100 version is initiated. If the version of the distant office test line is known, then that version of the test line can be performed directly, and thus the two-second delay per trunk of the T100 test line test is eliminated.

The 101 test line is used to establish two-way communications between the test position and any trunk incoming to the system. The connection to the 101 test line is established through the switching network.

The 102 test line, also known as the milliwatt line, applies a 1004 Hz test tone towards the originating office to facilitate simple one-way or automatic transmission loss measurements. The test tone is applied for a timed duration of nine seconds during which answer (off-hook) signal is provided. Then an on-hook signal followed by a quiet termination is transmitted to the originating end until the connection is released by the originating end.

The T103 is used for the overall testing of supervisory and signaling features on inter- toll trunks. The test is performed to the far end to check overall supervisory and signaling features of the trunk. If the test fails or if a false tone signal is detected, the test is abandoned and the condition indicated.

The T104 test, used for two-way transmission loss measurements, far-to-near noise measurements and near-to-far noise checks is normally used in testing toll trunks.

When a 105 test line at a far-end office is called and seized, timing functions are initiated and an off-hook supervisory signal and test progress tone are returned to the originating office. If the responder is idle, the test line is connected to the responder and test progress tone is removed. Transmission tests are then initiated.

The T108 test provides far-end loop-around terminations to which a near-end echo suppression measuring set is connected for the purpose of testing echo suppressors.

北电网络交换术语。100测试线，又称为静态终端或平衡终端。用于噪声和损耗测量。S100仅为噪声测量提供一个静态终端。在100系列中，有T100，S100和N100测试。其中，N100是最新的测试方案，同样包括毫瓦测试（即102测试线）并且能够完成由远到近损耗测量。T100用于终端局设备未知的时候。当完成T100测试线连接后，引入一个2秒超时参数以检测线路是否存在毫瓦信号音。若T100测试线检测到毫瓦信号音，那么线路将执行N100测试方案。否则，将启动S100方案。若远端局测试线方案已知，那么将直接执行该方案测试线。T100测试线的每根中继线2秒延时测试将被取消。

T101测试线用于建立测试位置和任何系统入中继之间的双向通信。与101测试线的连接是通过交换网络来建立的。

T102测试线，又称毫瓦线，向发端局提供一个1004HZ测试音以完成简单单向或自动传输损耗测量。在线路提供应答（摘机）信号期间，T102测试线将提供一个为时9秒的测试音。然后线路向发起端传输一个伴有静态终端的挂机信号直到始发端中断连接。

T103测试线用于长途局间中继线上所有监控和信令功能测试。该测试线在远端完成测试，以检测中继线上所有监控功能和信令功能。如果测试失败或者是检测到错误的单音信号，那么线路将放弃测试并显示当前状态。

T104测试线。用于双向传输损耗测量，由远至近噪声测量以及通常用于测试长途中继线的由远至近的噪声。

当远端站的T105测试线发起呼叫并被扑捉到时，定时功能启动，摘机监控信号及测试过程音返回始发局。如果应答器空闲，那么测试线将与应答器连接，测试过程音将消失，然后传输测试将启动。

T108测试提供远端环路终端，该终端与近端回声抑制器测量装置相连接用于测试回声抑制。
