bellcore

基本解释

The Bellcore GR-253 standard for SONET networks defines the bytes over which a particular parity error is calculated.
符合Bellcore GR - 253 SONET网络标准定义了一个特定的奇偶校验错误计算的字节。
To fix this, Bellcore had to invent a low-tech, low-functionality, high-complexity protocol called Analog Display Services Interface (ADSI).
为了解决这个问题，贝尔发明了一种低技术、低功能、高复杂性的协议，称为模拟显示服务接口（ADSI）。
A copy of the Bellcore specification can be made available if you are interested. This Standard has been in effect for over20 years with excellent results.
如果感兴趣，我们可以提供此标准的复印件。此标准实施已经20年多年了，成果卓著。
