T1 (RJ45) interface connections to 303-1111-900 shelf interface panel
Run the T1 cables from the modem shelf to the allocated positions on the DDF/Backhaul. 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 T1 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 RJ45 Connectors. Terminate as detailed below.
Connect the T1 ports on the DDF to the T1 RJ45 adapter fitted to the slot 5 connector on the
shelf interface panel. Ensure that the respective T1 ports have been configured on the
DDF/Backhaul. The Primary T1 should connect to port 5 and the Secondary T1 to port 6. The
first Modem Shelf in the rack distributes the secondary T1 quarters to the other modem
shelves in the CT and expansion Rack if used.
