Study on Video Transmission QoS of ISDN in Coal Mine

孤立例外是赢取了在一些住宅顾客的ISDN（综合业务数字网络）。

The lone exception has been ISDN ( Integrated Services Digital Network ) that has won over some residential customers .

在宽带综合业务数字网络（B-ISDN）中，ATM作为B-ISDN的核心技术，在通讯系统中占据了重要地位。

ATM technology is kernel in Broadband Integrated Services Digital Network ( B-ISDN ) and has taken up important place in the communications .

ATM网络正是支持这种综合业务数字网络的关键技术之一，已被国际电信联盟作为一项典型传输技术加以推广。

ATM is just one of the key technologies that support the Integrated Service Digital Network ( ISDN ), which is adopted as a typical technique by the International Telecommunication Union ( ITU ) and is spread .

ISDN即综合业务数字网络，在现有的交换机和基于V5接口的接入网设备上提供了大量的ISDN用户，很多商业用户和PBX还在使用ISDN接口，在下一代网络中实现ISDN业务势在必行。

ISDN is Integrate Service Digital Network . There are many ISDN users in current switch and access network equipment . Many business users and PBX are using ISDN interface today . It is necessary to realize ISDN service in NGN .
