3.3 Installing External Combiner
Note: The external combiner is ordered separately and supports up to four service inputs. The GX remote unit supports 3
services, requiring that the unused combiner input be terminated.
The 4x1 external combiner (AK-GX-FILT-COMB) combines the input signals of the four GX supported bands (e.g.
ESMR/CELL, PCS, LTE700 and EAWS) and transmits them through a single output port to the broadband service antenna.
3.3.1 Unpacking and Inspection
1. Open the shipping carton and carefully unpack each unit from the protective packing material.
2. Check your package contents to verify that the items in the packing list are included and that there are no signs of external
damage. If there is any damage, call your Corning Optical Communications service representative.
