Installation
51
Run the E1 cables from the modem shelf to the allocated positions on the DDF/Backhaul. In
partial equipped installations it may be appropriate to run sufficient 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.
Impedance Switch settings
Set the switches below the E1 out BNC connector to 120 ohm as shown below
E1 Shelf Interface Connections To RJ45
