Shelf Interface Panel 303-1111-900
75 Ohm Shelf Interface Connections
Run the E1 co-axial cables from the modem shelf to the allocated positions on the
DDF/Backhaul. (Two cables per shelf in normal working, four cables per shelf in protected
mode). In partial equipped installations it may be appropriate to run enough cables to cater for
a complete rack of equipment. This reduces the need to disturb original installation when
adding additional equipment.
Feed the E1 cables through the top left hand side of the rack, and down the front of the rack.
Identify and label each cable at both ends as well as the DDF/Backhaul positions.
Terminate all cables with BNC co-axial connectors.
Connect the E1 ports on the DDF to E1IN Slot 5 and E1OUT Slot 5 BNC connectors on shelf
interface connections located on the modem shelf interface panel.
Ensure that the respective E1 ports have been configured on the DDF/Backhaul
Tie in cables as necessary using suitable cable ties, trim, leaving no sharp edges.
For 75ohm working the switches below the E1 out BNC connector should be set as shown
below
