b) E1 Cabling (Switch Link)
From the site survey, confirm the location of the Digital Distribution Frame (DDF) if a DDF is
to be used or the Switch if the E1 feeds are fed directs to the equipment. The length of E1
feeds should not exceed 250 metres.
Note: This must be a SELV port of an EN 60950 approved product.
Run the E1 cables from the AC shelf to the allocated positions on the DDF. 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 hole on the most convenient 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.
a. Type 43 to 25wayD-type adaptors to the backplane sockets and terminate all cables with
Type 43 connectors (75ohm ) and fit according to the figure below .
