The following list of equipment is required to set up a protected radio link:
• Four MDR / Orion Digital Indoor Units
• Four MDR / Orion RF Units
• Two MDR / Orion Protection Kit 1U panels (Supplied with protection kit)
• Four / Eight DIU interface loom cables (Supplied with protection kit)
• Tributary channel interface cables to connect to the user network
• Two DIU auxiliary communications cables (Supplied with protection kit)
• Standard tools and cabling required to set up a MDR / Orion radio link
Illustrations of the Protection Kits can be seen in Figure 12
and Figure 13. Note from
the drawings that the Orion Protection Kit offers the ability to protect eight E1/T1
tributary channels. Thus, the latter could be used with either the MDR or Orion radios.
Follow the steps below at each site to interconnect and set up the protected radio
systems:
• Install each DIU-RFU system as described in the MDR / Orion User Manual
• Install the four / eight tributary channel Protection Kit panel in the rack mount
• Connect tributary paths A and B on the Protection Kit panel to the two installed
Digital Indoor Units using the provided DB-25 interface cables
• Link the two Digital Indoor Unit auxiliary ports of the Digital Indoor Units through
the DIU auxiliary communications cable
• Switch on the two units and configure the radios as explained in Section J.4.2
• Connect the tributary interface of the Protection Kit panel to the user network
through the preferred interface (DB-25 / RJ48)
NOTE Be sure to acquire the correction protection kit that matches the Digital Indoor
Unit type you intend to use.
