- Scope
- This standard specifies measurement methods for end-to-end protection switching equipment related to digital wireless relay systems. The measurement methods for N+1 switching configurations given in this standard are also applicable to N+2 switching configurations, as well as 1+1, dual-channel and hot standby configurations. The channel priority test described in Chapter 5 is only applicable to N+1 and N+2 switching configurations. In configurations where the protection switching equipment and the wireless terminal equipment are physically separable, the interfaces at the input and output ports of the switching equipment should be measured in accordance with YD/T 828.25.
