MSDH to idRU Connections 4.5.4
NOTE: In order to interconnect MSDH and idRUs, matching SFPs must be installed in elements on either
side of the link.
To connect idRUs to the MSDH
Recommendation for connections
x For more orderly connections and intuitive identification, it is recommended to connect idRU CPRI cables
to the higher numbered CPRI ports in the MSDH – i.e. Ports 16 and down to the available ports.
x The first ports are used for connecting to another MSDH – in case of Master Slave topology, and to
MTDI equipment.
Below is an example of a basic configuration consisting of two MTDIs and a number of remotes. In this
configuration, up to 14 remotes can be connected on Ports 3 to 16.
