Arrangement and method relating to communications systems |
摘要 |
A communications switching system includes a switching network and a number of access units. The switching network includes a number of multiplexing arrangements and a number of switching arrangements. In order to provide redundancy in the system, a number of multiplexing and switching arrangements are built together to form a number of combined multiplexing and switching arrangements, and a common protection switching arrangement is arranged to provide protection switching both between access units and multiplexing switching arrangements and between access units and accessing networks.
